Development of multi‐component non‐sex pheromone blends to monitor both sexes of <i>Cydia pomonella</i> (Lepidoptera: Tortricidae)

Nineteen host plant volatiles (HPVs) were screened for attractivity to adult codling moth Cydia pomonella (L.) as a fourth component of core blends (3K) including (E,Z)-2,4-ethyl decadienoate, (E)-4,8-dimethyl-1,3,7-nonatriene and acetic acid. Each new quaternary combination was compared with previously reported attractive bisexual lure (4K), consisting the 3K blend plus 6-ethenyl-2,2,6-trimethyloxan-3-ol (pyranoid linalool oxide, pyrLOX). All evaluations conducted in apple, Malus domestica (Borkhausen). Several compounds found significantly lower total and/or female catches when added blend, (Z)-3-hexenol, (E)-2-hexanal hexyl butanoate (female moths), (Z)-3-hexenyl acetate moths). Other did not increase or decrease catches, methyl salicylate, (E)-β-ocimene, limonene, β-caryophyllene, butyl hexanoate, farnesol, terpineol, terpinen-4-ol α-pinene. A few increased β-pinene (male (Z)-jasmone (E)-β-farnesene β-myrcene (E,E)-α-farnesene (male, female, In addition, each these five performed similarly 4K females, Further studies should expand results through tests other range ratios loading amounts. Field trials also be replicated within all crops across major geographical production regions.
