Abstract

Each of three insecticides—lindane, carbaryl, chlorpyrifos—was tested by topical application on the western pine beetle, Dendroctonus brevicomis LeConte, and two native coleopterous predators, Enoclerus lecontei (Wolc.) and Temnochila chlorodia (Mann.), to assess comparative toxicity. Lindane was more toxic to the predators than to western pine beetle, while carbaryl was relatively non-toxic to E. lecontei when compared with either T. chlorodia or western pine beetle. Chlorpyrifos was equally toxic to all three species. Results of topical application serve to estimate relative effects of insecticides on predacious associates in the western pine beetle community.

Résumé

Les insecticides lindane, carbaryl et chlorpyrifos ont tous 3 été testés par application locale contre le dendroctone occidental du pin, Dendroctonus brevicomis LeConte, et 2 coléoptères indigènes prédateurs, Enoclerus lecontei (Wolc.) et Temnochila chlorodia (Mann.), afin d'en évaluer la toxicité comparée. Le lindane était plus toxique pour les prédateurs que pour le dendroctone, alors que le carbaryl était relativement non toxique pour E. lecontei comparé à T. chlorodia et le dendroctone. Le chlorpyrifos était également toxique pour les 3 espèces. Les résultats des applications locales servent à évaluer les effets relatifs des insecticides sur les prédateurs associés à la communauté du dendroctone occidental du pin.
