摘要:
Maximum captures of male oriental fruit moths (OFM),Grapholitha molesta(Busck), in sticky traps were obtained with a blend of 95% (Z)-8-dodecenyl acetate (DDA) and 5% (E)-8-DDAplus dodecyl alcohol; however, captures of male pecan bud moths (PBM),Gretchena bolliana(Slingerland), were unaffected by alterations in the amount (from 0 to 20%) of theE-isomer. The hours of maximum response of OFM (5–8 pm) to (Z)-8-DDA differed markedly from the hours of maximum response of PBM (10 pm-3 am) but were about the same as those of the lesser appleworm (LAW),Grapholitha prunivora(Walsh). Response to pheromone traps at 4 different heights indicated that captures ofPBMwere greatest when traps were 9 m above ground, but moreOFMandLAWresponded when they were 1 m above ground.Air-permeation trials with microencapsulated (Z)-8-DDA applied at rates of 2 and 8 g lure/acre, suppressed response of male OFM to traps baited with virgin females. On the basis of captures of released-marked males in the untreated orchard, suppression was 77–98% in the orchard treated with 8 g lure/acre for the 5 wk after treatment. The recapture rate of the released males by pheromone traps in the untreated orchard was quite high (69%).
