Abstract:The effects of the insecticides carbaryl, aminocarb, and fenitrothion on spruce budworm, ChoTistoneura fumiferana (Clemens), food consumption were evaluated in no-choice and choice laboratory assays. Four concentrations of the chemicals (:$LC.,,) incorporated into diet and fed to six instars for 72 h. In no-choice assays, larvae exposed to levels ∼10 ppm carbaryl, ∼0.5 ppm aminocarb, and ∼2 ppm fenitrothion consumed significantly less food than those fed untreated control diet. Larvae consumed significantly less treated diet in choice assays containing levels ∼20 ppm carbaryl and ∼l ppm aminocarb. Spruce budworm did not feed lesson diet treated with fenitrothion in choice tests, but overall consumption was reduced.
