Abstract

Tumblers used to remove debris-feeding insects, predators of the leafcutter bee, excess leaf pieces, debris, and plant foliar molds from cells of the alfalfa leafcutter bee were compared. A hand-cranked tumbler removed significantly more material than did five motor-driven tumblers. It also removed more debris as the initial sample weight increased.

Résumé

Nous avons comparé le contenu des godets utilisés pour enlever les insectes détritivores, prédateurs de la découpeuse de la luzerne, les restes de feuilles, les débris et les moisissures foliaires des alvéoles de cette espèce d'abeille. Un godet déplacé à la main enlevait significativement plus de matière que cinq godets actionnés par un moteur. Il prélevait aussi plus de débris quand le poids de l'échantillon initial augmentait.
