Fleury, D., Bostanian, N.J., Mauffette, Y. and Vincent, C. (2007) Residual toxicity of two insecticides on three field populations of Lygus lineolaris (Hemiptera: Miridae) collected along the St Lawrence valley in eastern Canada. Pest Management Science, 63(5):495-499. (Scopus )

Résumé

Insecticides are still the single main pest control method employed today by most growers to mitigate damage done by the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae). In eastern Canada, the complex agricultural ecosystem, which may be described as a mosaic of farmlands dispersed among natural habitats (forest, prairies), allows tarnished plant bug adults to fly and move from sprayed to non-sprayed areas. In 2004 (late August to early September), three populations of L. lineolaris were collected from three mixed vegetation strips adjacent to orchards and vineyards along the St Lawrence valley: the Niagara Peninsula (Ontario), Dunham (Quebec) and La Pocatie?re (Quebec). Assays were done in the laboratory by confining adults in glass vials coated with dried residues. The estimated LC50 values for the three populations varied from 11.2 to 16.8 × 10 -5 g L-1 for azinphos-methyl and from 0.8 to 1.4 × 10-5 g L-1 for cypermethrin. In contrast to the Mississippi delta, no tolerance to insecticides was found in the populations collected. Possible explanations for this non-tolerance to insecticides includes a very low selection pressure as a result of the reduced number of insecticide treatments done in the context of the diversified agricultural landscapes encountered in eastern Canada which allow movements of adults from treated to non-treated areas. © 2007 Society of Chemical Industry.
