AB:  A steam distillate from the freshly cut young bark of coconut palm Cocos nucifera was analyzed by gas chromatography, combined gas chromatography-electroantennographic detection (GC-EAD) and GC-MS to detect host attractants for the curculionid weevil Rhynchophorus ferrugineus, one of the major coconut pests in Sri Lanka. A twin FID peak consisting of a minor and a major component was shown to possess electrophysiological (EAG) activity. The minor peak was identified as gamma-nonanoic lactone 1, while the major peak was identified as 4-hydroxy-3-methoxystyrene 2. In an EAG assay the synthetic racemic nonanoic lactone 1 did not elicit a considerable response in the antenna of R. ferrugineus, whereas the laboratory synthesized 2 showed activity. In a laboratory bioassay using a Y-type olfactometer, synthetic 1 and 2 elicited moderate attractant properties to R. ferrugineus, whereas a 1:1 mixture of the compounds showed increased attraction over that of the individual compoun!

AB:  Production of 4-methyl-5-nonanol, and 4-methyl-5-nonanone by two sympatric Asian palm weevils, Rhynchophorus ferrugineus (Oliv.) and R. vulneratus (Panz.) suggested that enantiospecificity of either compound could impart species specificity of pheromone communication. Weevil-produced, racemic 4-methyl-5-nonanol and 4-methyl-5-nonanole and their stereoselectively synthesized optical isomers were subjected to gas chromatographic-electroantennographic detection (GC-EAD) and GC-mass spectrometry (MS) on a chiral Cyclodex-B column. Only the S,S stereoisomer of 4-methyl-5-nonanol was EAD active and was produced by both R. ferrugineus and R. vulneratus. Production and EAD activity of (S)-4-methyl-5-nonanone exceeded that of its antipode in both weevils. In field experiments in Java, (4S, 5S-)4-methyl-5-nonanol and the stereoisomeric mixture were equally attractive. The 4R,5R stereoisomer was inactive. The corresponding ketone enantiomers neither enhanced nor reduced attraction t!
o (4S,5S)-4-methyl-5-nonanol. Lack of apparent differences between R. ferrugineus and R. vulneratus pheromones suggests that synonomy of both weevils should be considered unless other pre- or postzygotic reproductive isolating mechanisms are disclosed in future studies.

AB:  Protocols for pheromone-based mass-trapping of the Asian palm weevil, Rhynchophorus ferrugineus, are presented. The aggregation pheromone, ferrugineol (4-methyl-5-nonanol) released at 3 mg per 24 h was numerically, but not statistically, superior to lower doses, and this rate is recommended for operational trapping programmes. Trap captures were maximized by placing traps at ground level or 2 m high. Vane traps were superior to bucket traps. Insecticide-free traps containing funnels to prevent weevil escape were equally as effective as traps using insecticide to retain weevils. Synergism between ferrugineol and host palm volatiles was demonstrated and necessitates the inclusion of palm material in traps for maximum trapping efficacy. Both the Asian palm weevil and coconut rhinoceros beetle, Oryctes rhinoceros, were captured in the same traps without interference between their respective pheromones. These results have led in part to pheromone-based mass-trapping of the Asi!
an palm weevil throughout the Middle East where the weevil is a serious introduced pest of date palms.

AB:  Insect pest occurrence on the red oil palm (Elaeis guineensis, which is now grown to a limited extent in India) was surveyed in government owned plantations on 2 estates in Kerala, established in 1971-84. The oil palm is attacked by 2 beetle species (Oryctes rhinoceros, Rhynchophorus ferrugineus) and one moth (Dasychira mendosa [Olene mendosa]), for which details of damage and biology are given. A grasshopper (Orthacris sp.) and a termite species (Heterotermes malabaricus) also attacked the oil palms. Other pests were rodents and crows. The attack by these pests adversely affects seed production. Suitable control measures are described for the 2 beetle species, and for the rodents and crows. It is suggested that strict quarantine regulations should also be enforced against any inadvertent introduction of insects from its native home or other countries.

AB:  The red palm weevil, Rhynchophorus ferrugineus, invaded the Gulf states in the mid-1980s, where it is now causing severe damage to date palms. This polyphagous insect is widely found in southern Asia and Melanesia where it is a well-known problem for the damage it causes to coconuts grown in plantations. In this region, the weevil is sympatric with four other Asian Rhynchophorus species but the taxonomic status of some of these is unclear and some may be conspecific with the red palm weevil. Current tactics to manage the weevil in the Gulf and Asia are largely based on insecticide applications although there are now deep concerns about environmental pollution. Much research has been conducted on other techniques, notably pheromone traps. However, there is now a strong emphasis on the development of integrated pest management (IPM) based on pheromone traps and biological control rather than insecticides. The biogeography, basis of population outbreaks and current managemen!
t tactics for the red palm weevil and related species are reviewed, and the potential of biological control to underpin the development of an IPM programme is assessed.

Adult longevity, biotic potential (fecundity), fertility and egg mortality rate, larval and pupal duration (and associated mortality rates) and duration of the complete cycle were measured, as well as rearing performance (both in mass rearing and in individual rearing conditions). The range of host palm species was studied in the introduction area (Almunecar, Granada). The results showed a slight reduction in the mean values of adult longevity and biotic potential and a slight increase in the mean values of the different growth phases. The main host plant in Almunecar was Phoenix canariensis (Palmaceae). Adults of R. ferrugineus showed a marked reluctance to move in their new occupancy area. Some hypotheses that may explain this phenomenon are outlined.

AB:  R. ferrugineus were collected from diseased coconut trees at Kayamkulam, India, and their midguts investigated. The midgut of R. ferrugineus larvae were divided into the anterior saccular midgut, anterior tubular midgut, posterior saccular midgut and posterior tubular midgut. The pH of the anterior saccular midgut contents was 5.0-5.4. The effect of extracts of the midgut epithelium on the maintenance of gut pH in final-instar larvae was studied in vitro. Ligated tubes of the anterior saccular midgut, filled with pH indicator-buffer solutions at pH 4 or 7, were incubated with a midgut epithelial extract at 37°C. The pH of the contents of the midgut preparations returned to the normal range (5.0-5.4) following incubation with the epithelial extract, as indicated by a colour change. The effect was both dose- and time-dependent. No change in colour was observed in controls incubated with insect saline for 60 min. It is suggested that the midgut epithelial factor regulating g!
ut lumen pH could be a hormone.

AB:  This evaluation of pesticides was carried out in two assays, the first with 7-day-old larvae and the second with 1-month-old larvae of Rhynchophorus ferrugineus. In both cases, the insecticides were incorporated into the semi-artificial diet which is used to rear this species in the laboratory. The insecticides tested were a natural extract of neem tree seeds (azadirachtin at 3 cc/l) and EXP60720 A (fipronil at 1500, 0.4, 0.2, 0.1, 0.05 and 0.01 ppm). Efficacy values were obtained using the equation of Abbott 15 days after treatment. It showed that for the younger larvae, the mortality reached 100% at doses greater than 0.1 ppm of fipronil. On the other hand, the mortality caused by azadirachtin was less than 50%. Mortality of 100% was only reached for 1-month-old larvae with doses of fipronil exceeding 0.2 ppm.

AB:  On the basis of laboratory and field observations and a thorough bibliographic revision, a comparative examination is undertaken on biological and biogeographic features of different curculionid beetles of the Rhynchophorinae subfamily (Coleoptera) that could potentially become pests in Spain and other European Union states, notably the most southerly ones. A series of basic data on that taxonomic group are given, together with comments on preparation techniques. For each species, a brief description of adult, egg, larva and pupa is given. Lists of host plant species, areas of original geographic distribution and areas where species have been introduced are also given. It is concluded that, as potential pests, the two most threatening species are Rhynchophorus ferrugineus and R. palmarum. By contrast, Dynamis borassi, R. quadrangulus and Metamasius cinnamominus are thought to be of little economic importance. The rest of the examined species represent intermediate potenti!
al risks, although it is important to point out that R. phoenicis, R. vulneratus and R. bilineatus cause extensive damage to their host palms in Subsaharian Africa, Asia and Papua New Guinea, respectively. As an illustration of the Rhynchophorine life cycle, a detailed description is given of the life cycle of Rhynchophorus palmarum, studied in French Guiana.

AB:  In recent years, ornamental palm seedlings in Changhua area of Taiwan were predominantly attacked by weevil pests. The species of weevil pests, host seedlings, and ecology have been studied. Results showed that there were three palm weevil species: red palm weevil (Rhynchophorus ferrugineus), small weevil (Diocalandra frumenti) and asiatic palm weevil (Rhabdoscelus lineaticollis) attacked palm plants. The red palm weevil is the dominant pest, which breed on seedlings of Phoenix sylvestris, P. canariensis and Bismarckia nobillis. The distribution of this weevil included Tienwei, Yungching, Pitou, Chutang, and Chichou. Small weevil attacked Mascarena verchaffeltii, Roystonea regia and P. loureiri in in Chichou and Tienwei. Asiatic palm weevil attacked in M. verchaffeltii, occurred in Chichou and Tienwei. Asiatic palm weevil attacked in M. verchaffeltii, occurred in Tienwei. Durations of the egg, larval, pupal and adult stages for small weevil were ca. 6-10, 35-40, 10-16 and!
 15-22 days, respectively. The behaviours of these weevil pests are also described.

AB:  Studies in the Indian sub-continent on utilising insect pheromones for control are summarized. The pheromones of more than 20 insect pests have been identified and the behaviourally active components of 14 fully optimised. In addition, four components of the pheromone of Opisina arenosella were identified using insects from Sri Lanka. Putative pheromone components of Maruca vitrata, Leucinodes orbonalis, Hellula undalis, Xylotrechus quadripes and Rhynchophorus ferrugineus have been identified. The female sex pheromone of Aproaerema modicella has been identified and found to be highly attractive to male moths at very low doses. However, despite extensive investigation, the optimised pheromone of Helicoverpa armigera remains of uncertain value for use in population surveillance and control. A controlled-release formulation suitable for protecting a wide range of lepidopteran pheromones was developed and evaluated in large scale trials on cotton and rice pests in Pakistan an!
d India, respectively. In Pakistan, season-long control of the cotton pests, Pectinophora gossypiella, Earias insulana and E. vittella, was achieved by mating disruption, with a saving of up to 5 insecticide applications. In India, season-long control of Scirpophaga incertulas, on rice, was as effective as the insecticide regimes currently used by smallholders.

AB:  Rhynchophorus ferrugineus was first discovered in north-eastern Egypt in 1992 and has now become established as a primary pest of date palm in Egypt. Sizeable cavities are created in stem tissue by larval tunnelling, in which multiple generations may be completed. Even in advanced stages of infestation visible signs of stress are few and infestations are usually located by detection of exit holes. Experiments were carried out to examine the use of pheromone/food traps to determine seasonal variation of the abundance of adult R. ferrugineus and the effectiveness of traps for monitoring populations. Pheromone/food traps were strapped to date palms 3 m above ground to prevent vandalism and to be above off-shoots. Many more adults were captured during the warmer summer months than during the cooler winter months. The threshold for R. ferrugineus was found to be in the range 12-14°C with very low number of weevils being captured in December and January, the only months in whic!
h the average daily temperature fell below 14°C. Captures rates were highest in the months of April, May and June, which corresponds to the onset of warmer weather in Egypt. The higher capture rates during this period were probably due to the emergence of broods whose development was slowed by the cooler winter months. Twice as many female as male weevils were caught.

AB:  The curculionid Rhynchophorus ferrugineus is a devastating pest of coconut in Tamil Nadu, India. The insects remain right inside the trunk, feeding on the central tissue and the growing part resulting in the death of the tree. Any treatments with insecticides in the later stages of attack cannot save the palm. Experiments conducted with different natural phagostimulants showed that sugarcane molasses and toddy (alcohol extracted from coconut) attract the curculionids in large numbers. These substances can therefore be included as a component in integrated pest management as a bait to monitor the dynamics of the population. Further experiments with systemic insecticides showed that monocrotophos applied in the early stages of attack was efficient in controlling the pest.

AB:  The production of 4-methyl-5-nonanol and 4-methyl-5-nonanone by the sympatric curculionids Rhynchophorus ferrugineus and R. vulneratus suggested that enantiospecificity of either compound could impart species specificity of pheromone communication. Weevil-produced, racemic 4-methyl-5-nonanol and 4-methyl-5-nonanone and their stereoselectively synthesized optical isomers were subjected to GC-EAD and GC-MS on a chiral Cyclodex-B column. Only the S,S stereoisomer of 4-methyl-5-nonanol was EAD active and was produced by both R. ferrugineus and R. vulneratus. Production and EAD activity of (S)-4-methyl-5-nonanone exceeded that of its antipode in both curculionids. In field experiments in coconut plantations in Java, (4S,5S)-4-methyl-5-nonanol and the stereoisomeric mixture were equally attractive. The 4R,5R stereoisomer was inactive. The corresponding ketone enantiomers neither enhanced nor reduced attraction to (4S,5S)-4-methyl-5-nonanol. Lack of apparent differences between !
R. ferrugineus and R. vulneratus pheromones suggested that synonomy of both curculionids should be considered unless other pre- or postzygotic reproductive isolating mechanisms are disclosed in future studies.

AB:  Pseudomonas aeruginosa was identified as a facultative pathogen of Rhynchophorus ferrugineus, a pest of coconuts. Intra-haemocoelic injection of the pathogen within larvae and pre-pupae was more effective at killing the insects (with a median lethal dose (LD50) of 9 X 102 to 2 X 103 bacteria/insect) than inoculation by force feeding (LD50 of 105 to 4 X 105 bacteria/insect) or by wading (to wet the abdomen) in a suspension of the pathogen (LD50 of 105 to 2 X 105 bacteria/insect). Injection of 3 X 103 bacteria/insect killed 69% of larvae; small larvae were more susceptible (LD50 of 9 X 102 bacteria/larva) than either larger larvae (LD50 of 103 bacteria/larva) or pre-pupae (LD50 of 2 X 103 bacteria/pre-pupa). The median time to death of the small larvae following injection of P. aeruginosa was about 6 days but that following force feeding or wading was about 8 days. A secondary invader, Serratia marcescens, had no effect on the pathogenicity of P. aeruginosa but hastened dea!

AB:  4-Methyl-5-nonanol is a male-produced aggregation pheromone of Rhynchophorus bilineatus. The pheromone was identified by coupled GC-EAD and coupled GC-MS analyses of male- and female-produced volatiles. Analyses by GC-EAD and GC-MS of insect-produced and stereoselectively synthesized isomers of 4-methyl-5-nonanol on a Cyclodex B column, which separated isomers with baseline resolution, revealed that only (4S,5S)-4-methyl-5-nonanol was EAD active and produced by the males. In field experiments in cocoa plantations in Papua New Guinea, (4S,5S)-4-methyl-5-nonanol and a racemic mixture of diastereoisomers of (4S,5S)-4-methyl-5-nonanol enhanced attraction to males and females in sugarcane-baited traps. (4S,5S)-4-Methyl-5-nonanol is also an aggregation pheromone of 2 other curculionids, R. ferrugineus and R. vulneratus. The stereoisomeric mixture of 4-methyl-5-nonanol is currently used to manage populations of R. bilineatus in Papua New Guinea.

AB:  The coconut pest Rhynchophorus ferrugineus shows short range attraction to coconut sap, whose volatile constituents consist mainly of short chain alcohols. In this study, electrophysiological responses of male and female antennae to four alcohols in coconut sap, viz. ethyl, n- propyl, n-butyl and n-pentyl alcohols were recorded. Pentanol, which constitutes a major portion of the coconut sap, elicited the greatest response in the antennae of both male and female R. ferrugineus (EAG/EAGmax = 0.85 SD, ± 0.16) and this response was significantly different from that of the control as well as those of the ethanol and n-butanol (EAG/EAGmax = 0.24 and 0.32 respectively). n-Propanol also had high EAG potency with EAG/EAGmax = 0.52, SD ± 0.15 which was not significantly different (P > 0.05 ANOVA, Scheffe's test) from that of n-pentanol. To compare the activities of the above alcohols with C6 to C10 n-alcohol, EAGs of hexanol up to decanol were also recorded under the similar condit!
ions. Results showed that the activity of pentanol was still the highest in the series, while that of hexanol (EAG/EAGmax = 0.83, SD ± 0.16) was not significantly different from it. Heptanol elicited moderate activity (EAG/EAGmax = 0.52, SD ± 0.15) which did not differ significantly from those of propanol, pentanol and hexanol. Other alcohols at the higher end of this series viz. octanol and nonanol had lesser EAG potencies (EAG/EAGmax = 0.35, SD ± 0.13 and 0.25, SD ± 0.09, resp.) which were not significantly different from that of the control (EAG/EAGmax = 0.16, SD ± 0.06). The lowest EAG response of EAG/EAGmax = 0.19 (SD ± 0.05) was shown by decanol and this response was also close to that of the control.

LA:  English
AB:  Electroantennogram (EAG) response of male and female Rhynchophorus ferrugineus to sixteen terpenes were determined. The chemoreceptivity of R. ferrugineus was sensitive to the size and the position of the oxygen function, degree of unsaturation and the arrangement of olefinic bonds in the molecules. A significant (P <0.001, t-test) reduction of the EAGs of terpene alcohols was observed when hydroxyl groups were acetylated. Thus linalool and terpineol (EAGs 17.50 and 17.52, resp.) elicited EAGs of 11.24 and 12.36, resp., with the corresponding acetates. The antennal responsiveness of R. ferrugineus to terpene alcohols did not differ significantly from their corresponding carbonyl analogues. Terpenes bearing non-terminal OH/C=O had higher EAG potency significantly different (P <0.001) from those with terminal -OH/C=O. Combining these findings with the olefinic moieties of the molecule, the terpenes could be divided into two classes: terpenes with 3 unsaturations, 1-3 unsatu!
ration with non terminal -OH/C=O and cyclic structure with non-terminal -OH/C=O; and terpenes having isolated diene systems, terpenes with terminal OH/C=O and terpenes having both of the above characters. Comparison of EAG activities of the two classes indicated that the former category had greater EAG potency (class mean 18.6), significantly different (P <0.001, t-test) from the latter (class mean 14.9). However, even the most favoured structure elicited lesser EAG response than the natural host attractant, isolated from steam volatiles of coconut bark (EAG 31.49).

M. rumphii is not as good a source of sago starch as the more widely exploited smooth stemmed M. sagu. M. rumphii is felled at 12-15 yr old just before flowering and when the starch level is highest. The palm is felled so that it falls across vegetation above the water level, and a length of about 8-10 m is prepared for raising sago grubs by removing the cortex; the stump is also used. Oviposition occurs naturally. The life cycle, growth, harvesting, marketing, and cooking and nutritional value of the grubs is described.

Adults were tagged by inserting pieces of radioactive Iridium wire, 192Ir into the flight muscles. This did not affect the ability of adults to fly. In the field in Sri Lanka the initial activity of the isotopes at 1 m was reduced to 30-40% at 18 m. The half-thicknesses of fresh and dry coconut timber for radiation emitted by 192Ir were 88 and 100 mm, respectively, and 870 and 1060 mm for radiation from 131I. 192Ir was used for labelling because it has a greater half-life than 131I and pieces of wire could be inserted into the insects.

AB:  Integrated management of the insect pests of coconut, cashew, pepper and cocoa was reviewed in a paper presented at a workshop on insect pest management strategies in coffee, cardamom and tea cropping systems held in India in 1986. Treatment of breeding sites with insecticides and release of predators and pathogens such as the reduviid Platymeris laevicollis and the fungus Metarhizium anisopliae may be used for the control of the scarabaeid Oryctes rhinoceros on coconuts. The Baculovirus of O. rhinoceros is a successful microbial control agent which occurs naturally in Kerala. The xyloryctid Opisina arenosella, also on coconuts, is attacked by parasitoids such as the braconids Apanteles taragamae and Bracon hebetor, the bethylid Goniozus nephantidis, Elasmus nephantidis, the eulophid Trichospilus pupivora, the chalcidids Brachymeria nosatoi, B. nephantidis, B. lasus, B. hime attevae and Antrocephalus hakonensis and the ichneumonids Xanthopimpla punctata, X. nana nana and !
Xanthopimpla sp. and predators including the carabids Parena nigrolineata and Calleida splendidula, the reduviid Sphedanolestes aurescens and many spider species. The curculionid Rhynchophorus ferrugineus may be controlled by prophylactic treatment of wounds and integrated control incorporating cultural methods and the application of insecticides such as heptachlor and BHC [HCH] may be used against the scarabaeid Leucopholis coneophora. Control of the cerambycid Plocaederus ferrugineus on cashew trees may be achieved by the early application of HCH and the adoption of phytosanitary methods. The mirid Helopeltis antonii is controlled by 3 insecticide sprays, at the emergence of new flushes, panicles and fruit setting. The chrysomelid Longitarsus nigripennis may be controlled on pepper [Piper nigrum] by soil application of insecticides, cultural methods and spraying with endosulfan and quinalphos. On cocoa, spot applications of fenthion or monocrotophos (at 0.05%) and the releas!
e of the coccinellid predator Cryptolaemus montrouzieri can be used against Pseudococcus lilacinus [Planococcus lilacinus] and Pseudococcus citri [Planococcus citri].

In a section on diseases and pests, it is considered that only a very few diseases and pests of such palms are known and none of them appears to cause economic damage. In Sarawak, Rhynchophorus vulneratus (Panz.) (schach (F.)) and R. ferrugineus (Ol.) are the major pests recorded. Oryctes centaurus Sternb. has also been found attacking the palms. In East Sepik District of Papua New Guinea, larvae of a blue butterfly develop in the trunks. The larvae of the main pests, particularly Rhynchophorus spp., are also considered to be a delicacy in many areas and this may explain why such pests are kept at low levels.
