Trap captures of male larch casebearer moths C. laricella (H b.) in response to the primary female pheromone (Z)-5d ecen -l-o l strongly decreased on addition of either the cor­ responding acetate analogue (a previously reported in­ hibitor) or the longer-chain homologue (Z)-5-dodeeen-lol. Various other m onoenic acetates or alcohols tested did not affect captures. Comparison with results on ot...

Abstract The present study was based on the idea of a pheromone trap barrier with alternating dispensers releasing different mixtures that affect males and females differently. We tested possibility increasing catch efficacy barriers by altering mixture low levels cis-Verbenol (cV, targeting males, BM), high cV (targeting females, BF) intermediate (SL). In addition, we were interested in loweri...

Pheromone-baited traps are often used in ecological studies of the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae). However, differences in trap captures may be confounded by trap design, trap location relative to a windbreak, and changes in local weather. The objectives of this experiment were, first, to examine differences in 0. nubilalis adult (moth) captures among ...
