Extracts of female sex pheromone glands of the sand Salix carpenterworm moth, Holcocerus arenicola, a serious pest of desert thicket, were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Based on comparison of retention times and mass spectra of synthetic standards, four compounds were identifi ed as cis-7-tetradecen-1-ol (Z7 - 14:OH), cis-5-tetradecen-1-yl acetate (Z5 - 14:OAc), cis-7-tetradecen- 1-yl acetate (Z7 - 14:OAc), and cis-9-hexadecen-1-yl acetate (Z9 - 16:OAc) with the ratio of 24:39:100:43. Electroantennographic (EAG) analyses of these standard chemicals and their analogues showed that Z7 - 14:OAc elicited the largest male EAG response, followed by Z5 - 14:OAc and Z9 - 16:OAc. In fi eld trials, traps baited with either Z7 - 14:OAc or Z5 - 14:OAc captured males while Z7 - 14:OH-, Z9 - 16:OAc- or solvent-baited traps caught no males. Z7 - 14:OAc as a single component was signifi cantly more attractive than Z5 - 14:OAc alone. The combination of Z7 - 14:OAc and Z5 - 14:OAc showed an evidently synergistic effect and attracted much more males than the individual compounds in the field. Addition of Z7 - 14:OH to the blend of Z7 - 14:OAc and Z5 - 14:OAc enhanced slightly the trap catches. We conclude that the major components of the sex pheromone of H. arenicola are Z7 - 14:OAc and Z5 - 14:OAc. Currently, a triangle trap baited with the synthetic compounds Z7 - 14:OAc, Z5 - 14:OAc, and Z7 - 14:OH in a 1:0.4:0.25 ratio at 825 μg/trap dosage can be effectively used to monitor the H. arenicola population level and catch the males within the desert regions in China.

AbstractThe monoterpenes (±)-α-pinene, (1S)-(−)-β-pinene, (R)-(+)-limonene, and myrcene did not enhance the catch of red pine cone beetle, Conophthorus resinosae, in traps baited with the female sex pheromone, (±)-trans-pityol. Traps placed in the upper half of the tree’s crown caught significantly more beetles than those hung from the tree’s trunk 2 m above ground. No significant differences in trap catches were found among standard yellow Japanese beetle trap tops and those painted red, green, blue, white, black, or yellow.

We discovered that extracts of the female sex pheromone gland of the carpenterworm moth Isoceras sibirica Alpheraky, a pest of Asparagus offi cinalis Linn., contained (Z)-7- tetra decen-1-ol (Z7 - 14:OH), (Z)-9-tetradecen-1-ol (Z9 - 14:OH), (Z)-7-tetradecenyl acetate (Z7 - 14:Ac), (Z)-9-tetradecenyl acetate (Z9 - 14:Ac), and (Z)-9-hexadecadecenyl acetate (Z9 - 16:Ac). The average levels of the chemicals in a single sex pheromone gland of a calling moth were (0.71 ± 0.24) ng, (1.42 ± 0.44) ng, (4.36 ± 0.32) ng, (8.71 ± 0.26) ng, and (0.82 ± 0.38) ng, respectively. The electroantennography (EAG) analysis of these chemicals and their analogues demonstrated that Z9 - 14:Ac triggered signifi cantly the male EAG response. Traps with rubber septa lure impregnated with Z9 - 14:Ac (500 μg/septum), Z7 - 14:Ac (250 μg/septum), and Z9 - 16:Ac (50 μg/septum) were more effective in catching male moths than traps with other baits or virgin females. Addition of Z7 - 14:OH and Z9 - 14:OH to rubber septa did not enhance the effi ciency of the trap.

AbstractDelta and wing traps baited with synthetic female sex pheromone of Leucinodes orbonalis Guenée were found to catch and retain ten times more moths than either Spodoptera or uni-trap designs. Locally-produced water and funnel traps were as effective as delta traps, although ‘windows’ cut in the side panels of delta traps significantly increased trap catch from 0.4 to 2.3 moths per trap per night. Trap catch was found to be proportional to the radius of sticky disc traps in the range 5–20 cm radius, discs with a 2.5 cm radius caught no moths. Wing traps placed at crop height caught significantly more moths than traps placed 0.5 m above or below the crop canopy. Replicated integrated pest management (IPM) trials (3 × 0.5 ha per treatment) were conducted in farmers fields with young and mature eggplant crops. Farmers applied insecticides at least three times a week in all check and IPM plots. In addition pheromone traps were placed out at a density of 100 per ha and infested shoots removed weekly in the 0.5 ha IPM plots. Pheromone trap catches were reduced significantly from 2.0 to 0.4 moths per trap per night respectively in check and IPM plots in a young crop and 1.1 to 0.3 moths per trap per night in check and IPM plots respectively in a mature crop. Fruit damage was significantly reduced from an average of 41.8% and 51.2% in check plots of young and mature crops respectively to 22% and 26.4 respectively in the associated IPM plots. Significant differences in pheromone trap catches and fruit damage were attained four and two weeks respectively after IPM treatments began in the mature crop whereas in the immature crop significant differences were not observed for the first eight to nine weeks respectively. The relative impact of removing infested shoots and mass trapping on L. orbonalis larval populations was not established in these trials but in both cases there was an estimated increase of approximately 50% in marketable fruit obtained by the combination of control techniques compared to insecticide treatment alone.
