Abstract

Twenty species of predaceous mites were collected from apple foliage in Maine during a 2-year survey of commercial and abandoned orchards. Phytoseiids and stigmaeids comprised 97.3% of the total mites. The phytoseiid Amblyseius fallacis (Garman) was the predominant predaceous species in commercial orchards. Predaceous mites were collected in commercial orchards primarily in the latter part of the growing season following cessation of spraying. In abandoned orchards, the stigmaeid Agistemus fleschneri Summers was the most abundant predaceous mite, with the phytoseiids Phytoseius macropilis (Banks) and Typhlodromus pomi (Parrott) also frequently collected. In abandoned orchards, predaceous mites were collected throughout the season and were generally more abundant.

Résumé

Vingt espèces de mites prédatrices ont été relevées sur du feuillage de pommier au Maine, au cours d’une étude de 2 ans portant sur des vergers soit en production, soit abandonnés. Du total, 97.3% des mites inventoriées étaient des phytoseiides ou des stigmaeides. Dans les vergers en production, le phytoseiide Amblyseius fallacis (Garman) fut la principale espèce prédatrice relevée, et les mites prédatrices ont surtout été échantillonnées en fin de saison après l’arrêt des arrosages. Dans les vergers abandonnés, le stigmaeide Agistemus fleshneri Summers était l’espèce prédatrice la plus abondante, mais les phytoseiides Phytoseius macropilis (Banks) et Typhlodromus pomi (Parrott) étaient également abondants. Les mites prédatrices ont été relevées tout au long de la saison dans les vergers abandonnés, et elles y étaient généralement plus abondantes.
