Abstract

A distribution study of stored-product and other insects in unswept, empty farm granaries was conducted in Manitoba in 1981, in Saskatchewan in 1982, and in Alberta in 1984.

Thirteen species of stored-product insects were found in Manitoba and Saskatchewan and 12 in Alberta, indicating uniform geographical distribution among the number of pest species throughout the prairies. The most common was Tribolium audax Halstead, followed by Cryptolestes ferrugineus (Stephens) and Tenebrio molitor L. Nine fungus-feeding species were found in Manitoba, 12 in Saskatchewan, and 12 in Alberta. The most common fungus feeders were Lathridius minutus (L.), Corticarina cavicollis Mann., Cryptophagus varus W.&C., and Corticaria serrata (Paykull). Five non-stored product species of insects that were scavengers, predators, or were sheltering in the granaries were found in Manitoba, 31 in Saskatchewan, and 10 in Alberta.

The distribution of six stored-product species, two fungus-feeding species, and one scavenger did not show a uniform abundance in the three prairie provinces, either in their distribution on farms or in granaries.

Résumé

On a étudié la distribution des insects des produits entreposées et des autres insects dans des cellules vides non-balayés des fermiers.

On a trouvé 13 espèces d’insects ravageurs des grains dans le Manitoba et la Saskatchewan mais 12 espèces dans l’Alberta indiquent une distribution uniforme des espèces. Les espèces les plus communs furent Tribolium audax Halstead, Cryptolestes ferrugineus (Stephens), et Tenebrio molitor L. On a trouvé 9 espèces fongivores dans le Manitoba, 12 dans la Saskatchewan et 12 dans l’Alberta. Les fongivores les plus communes furent Lathridius minutus (L.), Corticarina cavicollis Mann, Cryptophagus varus W.&C., et Corticaria serrata (Paykull). Des espèces qui mangent des débris, ou qui sont prédateurs, ou qui cherchent l’abri on a trouvé 5 dans le Manitoba, 31 dans la Saskatchewan et 10 dans l’Alberta.

La distribution et abondance de six espèces de ravageurs et deux espèces fongivores n’était pas uniforme ni au niveau provincial, ni dans les fermes, ni dans les cellules.
