Abstract
Ethyl (E,Z)-2,4-decadienoate (pear ester) is a kairomonal attractant for both male and female codling moth, Cydia pomonella (L.), in apple, pear and walnut. Studies were conducted in the western Untied States to evaluate the potential attractiveness of this kairomone for eight lepidopteran pests of these three crops, as well as, in cherry, peach/nectarine, apricot, plum, almond, pistachio, grape, kiwi, and citrus. The pear ester was loaded (10.0 mg) into gray halobutyl septa and insects were monitored with diamond- or delta-shaped sticky traps. Lures were not attractive to peach twig borer, Anarsia lineatella (Zeller); oriental fruit moth, Cydia molesta (Busck); omnivorous leafroller, Platynota stultana Walshingham; navel orangeworm, Amyelois transitella (Walker); apple fruitworm, Lacanobia subjuncta (Grote & Robinson); pandemis leafroller, Pandemis pyrusana (Kearfott); obliquebanded leafroller, Choristoneura rosaceana (Harris); and western tentiform leafminer, Phyllonorycter mespiella (Huebner). Additional studies with C. molesta populations attacking apple and pear would be useful.
