“…Field testing of candidate pheromones. Experiments 1-9 were conducted in Yunan in plantations of Arabica coffee with low to moderate CWSB densities (dϭproportions of infested plants) [Nestlé Experimental and Demonstration (E&D) Farm (30 km west of Jinghong; dϽ0.005), Dahaishan (55 km southwest of Mengla; dϾ0.050), Paliang (30 km southwest of Menglian; dϭ0.020), Dakaihe (25 km south of Simao; dϭ0.030), and Jinping (50 km east of Puer; dϭ0.040)], using Lindgren 4-funnel traps (Phero Tech Inc., Delta, British Columbia, V4G 1E9) and sticky delta traps (Gray et al, 1984). A small insecticidal Diclorvos cube (Green Cross, Division of Ciba Geigy Canada Ltd., Mississauga, Ontario, L4Z 2Z1) placed in the receptacle of funnel traps assured rapid death of captured beetles.…”

This study investigated pheromone communication and mating behaviour of the coffee white stem borer (CWSB), Xylotrechus quadripes (Coleoptera: Cerambycidae), in South Yunan, China. Coupled gas chromatographic-electroantennographic detection (GC-EAD) and GC-mass spectrometric (MS) analyses of volatiles released by male and female CWSB identified 2-hydroxy-3-decanone and 2,3-decanedione as male-specific candidate pheromones. Further GC-EAD and GC-MS analyses confirmed that only (S)-2-hydroxy-3-decanone is produced by male CWSB and elicits antennal responses by male and female CWSB. In field experiments, 2-hydroxy-3-decanone as a trap bait afforded capture of one female CWSB, and in laboratory experiments it weakly attracted female but not male CWSB. Complex mating behaviour in CWSB includes: 1) attraction of potential mates by both sexes; 2) repeated landings (with ever decreasing distance) of a female next to a male; 3) males dashing to a nearby female; 4) rejection of mating attempts by females; 5) post-mating female guarding by males; and 6) size-dependent mating success of males. Considering this complex mating behaviour, lack of direct flight towards pheromone sources, mating near pheromone-baited traps, and only moderate attractiveness of (synthetic) pheromone, pheromone-based trapping of females does not seem to be a viable strategy for managing CWSB populations in China.

“…Sticky 2-L milk-carton Delta traps (Gray et al 1984) were suspended from trees 2 m above ground and baited with a grey rubber septum (West Co., Lionville, Pennsylvania) impregnated with pheromone components in 10-100 pL of hexane (HPLC grade). Field experiments were conducted from 1994 to 1996, using single rows of mature (>40 cm diameter at breast height) ornamental cherry trees spaced >15 m apart along the boulevards of suburban streets in New Westminster and Vancouver, British Columbia.…”

The Canadian Entomologist 131: 85 -92 (1999) (E)-9-Dodecenyl acetate (E9-12:OAc) and (2,-9-dodecenyl acetate (Z9-12:OAc) are major components of the sex pheromone of the cherry bark tortrix (CBT), Enarmonia formosana (Scopoli), in British Columbia. The compounds were identified in extracts of female pheromone glands by coupled gas chromatographicelectroantennographic detection (GC-EAD) and coupled GCmass spectrometry.In field experiments, traps baited with E9-12:OAc or 29-12:OAc singly were unattractive to male CBT, but in combination at ratios of 50:50 or 40:60 captured numerous males. Increasing quantities of this two-component pheromone blend resulted in increasing captures of male CBT. This binary blend at a 10-mg dose caught more CBT males that did caged virgin CBT females. Eight other EAD-active acetates identified in extracts of pheromone glands failed to enhance attractiveness of the pheromone blend. These compounds may serve to reduce cross-attraction of heterospecific male moths or may play a role in courtship behaviour. Formulations of synthetic pheromone are being evaluated for management of the CBT using mass trapping or disorientation of male CBT moths. McNair, C., G. Gries et R. Gries. 1999.

Cages were placed in the middle of self-made sticky delta traps (Gray et al 1984) suspended from palms 1.5 m above ground at 27 m intervals. Captured males were recorded every 15 min from 17:30-23:00 hr.…”

Darna bradleyi Holloway, D. trima Moore, Setothosea asigna van Eecke and Setora nitens Walker are sympatric and coseasonal limacodid moths in plantations of oil palm, Elaeis guineensis Jacq. (Arecales: Palmae), in Borneo, southeast Asia. We tested the hypothesis that these four species maintain reproductive isolation through specificity in diel periods of communication, microlocation for communication and/or communication signal (pheromone). Studying diel periodicity of calling behavior by female moths and response by male moths to traps baited with virgin females or synthetic pheromone, we determined that sexual communication of D. bradleyi and D. trima took place from 17:30 to 18:45 hr and that of S. asigna and S. nitens from 18:45 to 20:00 hr and from 18:30 to 19:30 hr, respectively. Over 80% of male S. asigna and S. nitens were captured in pheromone-baited traps suspended \ 5 m high, whereas male D. bradleyi and D. trima were captured mostly in traps B 5 m high. Synthetic pheromone baits attracted male moths in a species-specific manner. Moreover, baits containing both S. asigna and S. nitens pheromones failed to attract any male moths, indicating that female S. asigna and S. nitens, with overlapping communication periods, use bifunctional pheromone components that attract conspecific males while repelling heterospecifics. Similarly, addition of D. bradleyi pheromone to S. asigna or S. nitens pheromone reduced attraction of male S. asigna and S. nitens. The failure of D. bradleyi and D. trima, which overlap in time and microlocation for communication, to evolve bifunctional pheromones may be attributed to the recent occurrence of sympatry between D. bradleyi and D. trima in Borneo, apparently too recent for bifunctional pheromones to have evolved. We conclude that D. bradleyi, D. trima, S. asigna and S. nitens utilize any or all of diel periodicity, intra and interspecific effects of communication signal and/or microlocation for signaling, allowing these limacodids to co-inhabit the same habitat and remain reproductively isolated.
