Abstract

One or more insects were captured during 1 week in probe traps placed in granaries holding wheat, barley, or oats in 51% (n = 116) of grain bulks in the fall of 1986, 88% (n = 111) in the summer of 1987, and 85% (n = 106) in the fall of 1987. Fungivorous insects were the most common and predominant group at all sampling times. Granivorous species were the rusty grain beetle, Cryptolestes ferrugineus (Stephens), and the red flour beetle, Tribolium castaneum (Herbst). Grain in galvanized steel and wooden granaries was usually infested with insects to the same extent; granaries with or without aeration systems usually contained the same number of species; small bulks of grain often were infested less frequently than large bulks; the presence of livestock feed on farms did not result in greater insect incidence; and insecticide use in granaries did not prevent re-infestation of grain and insecticide use increased from 24% in 1986 to 31% in the fall of 1987. The kinds of insects detected in grain stored with various farming practices, and co-occurrence with other arthropods in the grain provides baseline information on potentially changing patterns of infestation.

Résumé

Dans 51% des masses de céréales à l’automne 1986 (n = 116), 88% à l’été 1987 (n = 111), et 85% à l’automne 1987 (n = 106), un insecte ou plus a été pris pendant 1 semaine aux pièges de sondage, mis aux greniers contenant du blé, de l’orge or de l’avoine. Les insectes fongivores ont été parmi le groupe le plus commun et le plus important à chaque échantillonnage. Les espèces granivores étaient le cucujide roux, Cryptolestes ferrugineus (Stephens), et le tribolium rouge de la farine, Tribolium castaneum (Herbst). Les céréales entreposées aux greniers d’acier galvanisé ou du bois ont été infestées par les insectes au même degré; les greniers avec ou sans systèmes d’aération ont contenu normalement le même nombre d’espèces; à comparer aux grandes masses, les petites masses de céréales ont été moins souvent infestées; la présence du fourrage de bétail aux fermes n’a pas produit une plus grande incidence d’insectes; et les insecticides utilisés aux greniers n’ont pas empêché une réinfestation des céréales et l’utilisation d’insecticides a augmenté à partir du 24% en 1986 jusqu’au 31% à l’automne de 1987. Les genres d’insectes découverts aux céréales entreposées sous les conditions d’exploitations agricoles variées et l’occurrence des insectes avec d’autres Arthropodes trouvés aux céréales fournissent des renseignements de base concernant les modèles de changements possibles d’infestation.
