“…Individual males were released into the tunnel between the second and fourth hours of the scotophase according to previously outlined procedures (Muggleston & Foster 1989). In all the experiments, the pheromone source was a red rubber septum (Thomas Scientific Inc., Philadelphia) on which had been absorbed the appropriate amounts of (E)-l 1-tetradecenyl acetate (El l-14:OAc; Sigma Chemical Company, St Louis, Missouri; >99% isomerically pure as determined by capillary gas chromatography) and (E,E)-9,ll-tetradecadienyl acetate (E,E-9,ll-14:OAc, gift from Shin Etsu Chemical Co. Ltd, Tokyo, Japan; approximately 94% isomerically pure) in a ratio of 100:5 (Bellas et al 1983) dissolved in 25 \x\ of n-pentane. When not in use, the pheromone sources were stored at -15°C.…”

optomotor anemotaxis (the use of visual images to steer a resultant track and ground speed with respect to the wind) and by a behavioural mechanism that governs the rhythmic counterturning. Keywords Lepidoptera; Tortricidae; optomotor anemotaxis; orientation; behaviour Abstract The flight tracks (plan view) of male Epiphyas postvittana flying in a sex pheromone plume in a wind tunnel were recorded. With increasing source dosages (10, 100, 300 µg), males steered a more upwind course, with corresponding track angles more upwind, and had smaller intertrack reversal distances (i.e., they showed less lateral movement). Although net ground speed tended to increase with increasing source dosage, the effect was not significant. Increased wind speed (from 20 to 40 cm sec -1 ) resulted in little change in the apparent track of the males, but males increased their airspeed and steered a course more upwind in response to the increased downwind push and crosswind drift. Flight altitudes (source suspended at 5, 12.5, and 20 cm above the floor of the tunnel), had little effect on most flight parameters, except for ground speed and airspeed, which increased with increasing altitude, and which in turn resulted in increases in intertrack reversal distances. Finally, males steered a more upwind course and had a higher net upwind velocity when flying over a ground pattern of longitudinal black and white stripes than over a ground pattern of lateral black and white stripes. Across all treatments, the frequencies of turning back and forth across the windline were similar. These results are consistent with those observed in several other species of moths, and suggest that the pheromone-mediated flight of male E. postvittana is shaped by Z98022

“…These include insect growth regulators, spinosyns and Bacillus thuringiensis (Bailey et al 1996) In Australia, light brown apple moth has been managed in citrus, grapes and other crop systems using mating disruption (Mo et al 2006). Light brown apple moth pheromone has two key components, both of which must be present for optimal control (Bellas et al 1983;Suckling and Clearwater 1990). Presently, mating disruption is being implemented in some infested areas of California.…”

“…These same chemicals have also been found in certain Australian tortricine species (Horak et al 1988). There are, however, other species of New Zealand (and Australian, e.g., Epiphyas postvittana; Bellas et al 1983) tortricines that use the ~ 11-tetradecenyl compounds found in the palearctic tortricines (Foster & Dugdale 1988).…”

The sex pheromones of two endemic New Zealand tortricid species were investigated. Females of the first species, Cnephasia jactatana, a pest of kiwifruit, were found to produce (Z)-IItetradecenyl acetate (Zll-14:0Ac) in their sex pheromone gland. When tested in the field, this compound on its own elicited significant catches of male C. jactatana. However, the addition of even very small amounts (0.3%) of the geometric isomer, (E)-II-tetradecenyl acetate (E 11-14:0Ac), to Z 11-14:0Ac virtually suppressed trap catches. The sex pheromone of the second species, Merophyas leucaniana, was found to consist of a mixture of Zll-14:0Ac, EII-14:0Ac, tetradecyl acetate, and (Z)-11-tetradecenol. This species is morphologically very similar to the congeneric species, M. divulsana, Received 21 September 1992; accepted 26 February 1993 the Australian lucerne leafroller. The sex pheromone of M. leucaniana is also very similar to that of the so-called "Z-type" of M. divulsana, which is now found in New Zealand. The pheromone components of C. jactatana and M. leucaniana are discussed in relation to those found in other tortricids.
