Abstract

Wild codling moth, Cydia pomonella (L.), females were trapped from May through September in the upper (Yakima) and lower (White Swan) Yakima River Basin, WA, using 10 bait traps and 4 and 19 blacklight traps, respectively, for 2 and 5 years in abandoned apple orchards. The average spermatophore count per female at Yakima was 1.08; at White Swan it was 1.76. The spermatophore count was similar in both first (0.97 and 1.79) and second (1.00 and 1.70) generations at both locations. Regression analysis of field data and laboratory tests showed that cool temperatures reduced the number of spermatophores, which reflect reduced mating. There was a high correlation between the number of small spermatophores and females with multiple spermatophores. Usually females with a large spermatophore mated only once. Females usually mated on the 1st day following emergence. Once mated, even females with small spermatophores seldom mated again on subsequent days.

Résumé

Des femelles sauvages du carpocapse de la pomme, Cydia pomonella (L.) ont été piégées de mai à septembre dans le haut (Yakima) et le base (White Swan) du bassin de la rivière Yakima, Etat de Washington, à l’aide de 10 pièges appâtés, et de 4 ou 19 pièges à "lumière noire", respectivement, pendant 2 ou 5 ans dans des pommeraies abandonnés. Le nombre de spermatophores par femelle à Yakima était de 1,08 et de1,76 à White Swan. Dans les deux sites, ce nombre était similaire en première (0,97 et 1,79) et en seconde génération (1,00 et 1,70). L’analyse de régression des donnés du terrain et des lests de laboratoire ont montré que les basses températures réduisent le nombre de spermatophores, indiquant une baisse de l’incidence d’accouplement. On a observé une forte corrélation entre le nombre de petits spermatophores et l’incidence des femelles avec plusieurs spermatophores. Normalement, les femelles avec un gros spermatophore ne s’accouplaient qu’une seule fois. Les femelles s’accouplaient généralement le jour suivant l’émergence. Une fois accouplées même les femelles avec petits spermatophores s ’accouplaient rarement les jours subséquents.
