The attraction range of YATLORf pheromone traps to adults of four species of Agriotes (A. brevis, A. sordidus, A. litigiosus, and A. ustulatus) was studied to provide additional information about the most harmful Agriotes species in Europe. Male click beetles were marked and released at different distances from a pheromone trap. The recapture rate was calculated and analyzed using analysis of variance. The recapture rate was significantly affected by distance, species, and wind direction. The recapture rate decreased as distance increased. The majority of beetles were caught from short distances (up to 10 m) within the first five days. A. brevis, a mainly crawling species, showed the lowest recapture rate. The wind direction affected the recovery rate, with a significantly lower number of beetles moving downwind from the release points. Maximum sampling ranges and effective sampling areas were calculated. The obtained estimations were low (53 to 86 m and 509 to 2602 m2, respectively) for all the considered Agriotes species, suggesting that they were unsuitable for use as mass trapping instruments to disrupt mating. However, it seems possible to use the traps not only as monitoring tools, but also as attract-and-kill strategies for most beetle populations.

Frankliniella occidentalis  (Pergande) (Thysanoptera: Thripidae) adult male has sternal glands whose role is to produce pheromones. It is known that there are two major components in the headspace volatiles of thrips adult male that are not present in the headspace volatiles of adult female. Those components, (R)-lavandulyl acetate and neryl (S)-2-methylbutanoate were synthesized for the first time in Romania by "Raluca Ripan" Institute for Research in Chemistry (Cluj-Napoca). We have tested a blend of those in the greenhouse cucumber ( Cucumis sativum ) crops of University of Agricultural Sciences and Veterinary Medicine. Period study lasted in 4 weeks. Blue sticky traps were coated with insect glue on both surfaces and a rubber septum which contained the blend was attached in the center of a side of a trap. Two traps with pheromone lure and one trap without pheromone lure were hung up to a 20 cm distance from the tip of the plant. Both female and males were trapped. We observed a higher percentage of males on pheromone trap. Our data revealed that the total number of western flower thrips caught on pheromone traps ranged between 1537 and 1941 as compared with the total number of thrips caught on control trap (1333). According to our results we conclude that pheromone traps could be effective tools for F. occidentalis mass trapping and for the use in integrated pest management strategies.

Sex Pheromone Traps

Cocoa pod borer (CPB), Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae) is a major pest of cocoa. Detection of the pest infestation using sex pheromone traps in the early growth and development of cocoa pods is important for an early warning system programme. In order to prevent the pest infestation the young pods were wrapped with plastic bags. A research to study the CPB incidence was conducted at cocoa plantations in Banjarharjo and Banjaroya villages, District of Kalibawang; Hargotirto and Hargowilis villages, District of Kokap; and Pagerharjo village, District of Samigaluh, Yogyakarta. The experiments design used RCBD with four treatments (sex pheromone trap, combination of sex pheromone trap and pod wrapping, pod wrapping, and control) and five replications. As many as 6 units/ha pheromone traps were installed with a distance of 40 m in between. Results showed that one month prior to the trap installation in the experimental plots there were ripen cocoa pods as many as 9-13%, which were mostly infested by CPB. During the time period of introducting research on August to Desember 2016 there was not rambutan fruits as the CPB host, hence the CPB resource was from infested cocoa pods. The CPB moth trapped as many as 0−7 (1.13 ± 0.14) moths/6 traps/12 observations. The seed damage due to CPB larvae in the pheromone trap treatments (23.98%) was relatively similar with the control (20.25%). Seed damage rate in combination treatment of pheromone trap and pod wrapping (0.59%) was relatively the same with the pod wrapping (0.20%). The pheromone trap was more usefull for monitoring tool rather than for control, meanwhile pod wrapping was an effective control measure of CPB. IntisariPenggerek Buah Kakao (PBK), Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae) merupakan salah satu hama utama kakao. Deteksi serangan hama PBK dengan perangkap feromon seks pada awal pertumbuhan dan perkembangan buah kakao penting dilakukan sebagai sistem peringatan dini. Dalam upaya pencegahan serangan hama tersebut dilakukan pembrongsongan buah muda. Penelitian dilakukan di kebun kakao rakyat di Desa Banjarharjo dan Banjaroya, Kecamatan Kalibawang, Desa Hargotirto dan Hargowilis, Kecamatan Kokap, serta kebun PT Pagilaran di Desa Pagerharjo, Kecamatan Samigaluh, Yogyakarta. Percobaan dengan empat perlakuan (perangkap feromon, kombinasi perangkap feromon dan brongsong, brongsong, kontrol) dan lima ulangan menggunakan rancangan RCBD. Perangkap feromon sebanyak 6 unit/ha dipasang dengan jarak antar perangkap sekitar 40 m. Hasil percobaan menunjukkan bahwa satu bulan sebelum pemasangan perangkap terdapat buah tua sebanyak 9−13 % dan umumnya terserang PBK. Selama kajian berlangsung tidak terdapat buah rambutan sebagai inang PBK sehingga sumber PBK diduga hanya dari buah kakao yang terserang. Ngengat PBK yang tertangkap yaitu sebanyak 0−7 (1,13±0,14) ekor/6 perangkap/12 pengamatan. Intensitas kerusakan biji akibat ulat PBK pada perlakuan perangkap feromon (23,98%) relatif sama dengan kontrol (20,25%). Kerusakan biji kakao pada perlakuan kombinasi perangkap feromon dan pembrongsongan (0,59%) relatif sama dengan pembrongsongan saja (0,20%). Perangkap feromon lebih berfungsi sebagai alat monitoring daripada alat pengendalian PBK, sedangkan pembrongsongan buah merupakan teknologi pengendalian PBK yang efektif.

One of the most important pests of the stone fruit orchards is the oriental fruit moth (Grapholitha 1110/esta B.). Chemical control targeted against the young larvae is the most effective way of protection. so the ti ming of treatments has to be based on the observation of emergence. Emergence may be monitored with sex pheromone traps. It is already known from former publications, that the traps for oriental fruit moth are also effective in the case of the plum moth (Grapholitha f1111ebra11a Tr.), which external morphology is very similar to the oriental fruit moth. As the emergence of the oriental fruit moth in peach and apricot orchards has not been observed in detaib in Hungary, we started a s1Udy in this field. Our aim was to measure the selectivity of the sex pheromone traps. On the basis of examining more than 5000 males caught and the investigation of male genital ia. it could be established that the pheromone traps. Csalomon and Deltastop, for oriental fruit moth, caught the plum moth in the same ratio. The ratio of the oriental fruit moth and the plum moth trapped in the peach orchards was I: I . while in the apricot orchards the number of the caught plum moth males was seven times as many as that of the oriental fruit moths. Consequently, it can be established that data based on oriental fruit moth trap catches can not be used without additional investigations of genitalia for the prediction of larval hatch. The selectivity of the plum moth trap. used as a control. was acceptable in both orchards.

Batrachedra Amydraula

AbstractThe lesser date moth (LDM) Batrachedra amydraula is a significant pest of date palm fruits. Previously, detection and monitoring of the pest was inaccurate due to high costs of sampling with lifting machines. We report a practical system for detection and monitoring of LDM based on pheromone traps and relevant models. Dose–response experiments with LDM pheromone traps indicated a 1 mg lure is optimal for monitoring. Delta traps with adhesive covering their entire inner surface gave the highest captures while trap colour was unimportant. Sampling pheromone traps throughout the night indicated male flight began at 1:00–2:00 and reached a peak 2 h before sunrise. Monitoring traps exposed all year long in Israel revealed three generations with different abundance. Trapping transects in a date plantation indicated interference from a monitoring trap became minimal at distances >27 m away. Inter-trap distances closer than this may lower efficiency of monitoring and mass trapping in control programs. Our estimate of the circular effective attraction radius (EARc) of a 1 mg delta trap for LDM (3.43 m) shows this bait is among the most attractive compared with baits for other insects. We developed encounter-rate equations with the pheromone trap EARc to model the interplay between population levels, trap density and captures that are useful for detection of invasive LDM and its control by mass trapping. The integrated methodologies are applicable to many pest species.

The pheromone mass trapping programme for coconut black-headed caterpillar (BHC), Opisinaarenosella Walker under development at the south eastern dry zone of Karnataka calls for a proper monitoring system. Experiments conducted at Bidadi, Nelamangala, Nittur and Thyamagondlu near Bangalore, peninsular India to establish the emergence pattern of BHC indicated that nearly six emergence peaks of moths were recorded in 18 months. The duration of emergence and non-emergence periods of moths was approximately 41 days (SD= ±3.93) and 48 days (SD= ±4.35) respectively. The maximum number of days of moth and non-moth emergence was recorded during March, April and May. The studies on emergence pattern throughout the generation indicated that the moth emergence followed a normal curve. The moth emergence pattern of BHC in four coconut gardens at Nelamangala, Thyamagondlu, Nittur and Bidadi indicated the occurrence of spatially segregated moth emergence. The present studies provided thoughtful information on flight pattern of BHC in each generation and also throughout the year. Such basic results are helpful in designing pheromone based pest control strategies.

The research was carried out to determine the appropriate number of sex pheromone traps for monitoring the Spodoptera exigua moths in shallot crop which was grown in Yogyakarta Special Territory, Bantul Regency (Samas). This research was conducted in August until September 2016. Sex pheromone trap was arranged on shallot aged  3 weeks after planting. Sex pheromone trap with hexadecenat tetra asetat ingredients was placed on sticky yellow trap. This research  used RCBD experimental design with single factor experiment namely the number of trap i.e. 3, 5, 6, 8 units/2.000 m2 with sex pheromone, and  three traps without sex pheromone as control. Each treatment was repeated 5 times so  125 samples of experiments were obtained. Observation was made by counting the number of moths caught in sex pheromone trap. The result of observation was analysed  with analysis of variance (ANOVA) and DMRT α 5.0%. The results show that the appropriate number of trap to monitor the pest infestation was 3 units/2.000 m2.

Sex Pheromone Traps

The pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) is an important insect pest of the cotton crop worldwide. Sex-pheromone and light traps were used to monitor the adult P. gossypiella population in Bt cotton field for the years 2017-18 at southern Punjab, Pakistan. The sampling of infested bolls was done to record the damage level of P. gossypiella. The sex-pheromone traps captured approximately 2-3 times more adults than light traps in all locations during 2017-18. For sex-pheromone traps, temperature showed negative and strong relation (R2 = 0.63-0.80) with trap catches. Fewer bolls (7.0-9.0%) were infested in plots where sex-pheromone traps were installed compared to check plots (32-37%). Therefore, the pheromone trapping proved an effective and eco-friendly tool for the monitoring and management of P. gossypiella. Our findings enable forecasting of seasonal P. gossypiella population providing additional information for the development of an integrated pest management program for this pest.
