Pheromone Components

Biosynthesis of the major sex pheromone components of the obliquebanded leafroller, (Z)- and (E)-11-tetradecenyl acetates, is shown to proceed by Δ11 desaturation of myristate as in the related redbanded leafroller. A comparison between the amounts of deuterium label incorporated into the pheromone components from labelled myristic, palmitic and stearic acids gave a higher level of incorporation for the shorter chain acids, suggesting that Δ11 desaturation is a faster process than 2 carbon chain-shortening by β-oxidation.

The Mean

Effects of constant temperatures of 10, 15, 20, 25, 30 and 35°C on the preoviposition period and the effects of a constant 25°C on oviposition, fecundity, and longevity of the redbanded leafroller, Argyrotaenia velutinana (Walker), and the tufted apple bud moth, Platynota idaeusalis (Walker), were investigated. Oviposition did not occur at 35°C for either species and only the redbanded leafroller oviposited at 10°C. The threshold for oviposition for RBLR was calculated to be 8.7°C with 29.4 DD necessary for oviposition, while the oviposition threshold for TABM was calculated to be 10.5°C with 33.5 DD needed for oviposition. The mean oviposition periods for the two species did not differ; however, tufted apple bud moth longevity was significantly greater at 25°C. Fecundity was greater for the tufted apple bud moth (301 eggs/female) than for the redbanded leafroller (221 eggs/female).
