Uptake of the sex pheromone 3H-bombykol and related compounds by male and female Bombyx antennae

AbstractLoss rates of (Z)-8-dodecenyl acetate and related compounds from various dispensers were compared at 15, 20 and 29° C in the laboratory. Comparisons were also made of the performance of these dispensers in pheromone disruption trials against Cydia molesta (Busck) in peach orchards in Australia, in terms of the reduction of male captures at pheromone traps. Hollow-fibre and polymeric-laminate dispensers were superior to various polyethylene and silicone-rubber designs in providing a relatively constant release of pheromone in time, at rates readily modified by altering the dimensions of the dispensers.

AbstractMale and female laboratory reared spruce budworm moths, Choristoneura fumiferana (Clem.), were placed in cages in a conifer forest, and the surrounding air permeated by each of four blends of the E and Z isomers of the sex pheromone (11-tetradecenal) at two concentrations. Mating suppression of 53–83% was found for each blend tested. At one concentration the four suppressions were similar, while at the other only one was significantly different. Electroantennograms (EAGs) were obtained from male moths for each of six E:Z blends at four concentrations. EAGs were similar for most blends at a given concentration, but tended to be larger than at a blend of 0E:100Z.These results were discussed using a current hypothesis on the ability of males to detect sex pheromone in air containing pockets of different isomeric blends.

Mastrus Ridibundus

Insect aggregation pheromones are defined as chemical substances produced by members of one or both sexes that induce members of both sexes to form aggregations (Borden 1984). Aggregation pheromones are typically emitted by and attract adult insects. Interestingly, larvae of the codling moth, Cydia pomonella L. (Lepidoptera: Olethreutidae), seeking pupation sites will aggregate in response to pheromone produced by cocoon-spinning conspecific larvae (Duthie et al. 2003). Such aggregations may be part of a mating strategy in which protandrous males are arrested by sex pheromone emanating from mature female pupae, thus allowing mating to ensue as soon as a female moth ecloses (Duthie et al. 2003). The cocoon-derived pheromone also attracts the specialist prepupal parasitoid Mastrus ridibundus Gravenhorst (Hymenoptera: Ichneumonidae), which “eavesdrops” on pheromonal communication of cocoon-spinning larvae (Jumean et al. 2004).

AbstractThe cedar web-spinning sawfly, Cephalcia tannourinensis Chevin (Hymenoptera: Pamphiliidae), is a pest that has been causing serious damage to cedar (Cedrus libani) forests in Lebanon since 1990. The existence of a sex pheromone was shown in field experiments in a cedar forest in Lebanon and in laboratory tests in olfactometers with and without airflow. More males were caught in traps baited either with virgin females or with a hexane extract of the whole female body than in traps baited either with males alone or with mixed males and females. Male and female C. tannourinensis were active during the day. Mating and pheromone production were observed to occur during midday hours (1000–1400) in the field and under laboratory conditions. Olfactometer tests with extracts prepared from different body parts of the female indicated that the pheromone is produced in the abdominal region, and tests with different dilutions of female extract showed that the male response is dose-dependent.
