Abstract

Cypermethrin was more toxic to adults of the tarnished plant bug, Lygus lineolaris Palisot de Beauvois, in both laboratory and field studies, than other synthetic pyrethroid, organophosphorus, or chlorinated-hydrocarbon insecticides. The synthetic pyrethroids were more toxic than other groups of insecticides. Residues of cypermethrin were toxic to plant bugs for 7–10 days; other compounds were effective for shorter periods. In the field 1 application of cypermethrin effectively controlled tarnished plant bugs on peach.

Résumé

La cyperméthrine s'avère plus toxique pour les adultes de la punaise terne, Lygus lineolaris Palisot de Beauvois, dans les études en laboratoire et sur le terrain que d'autres insecticides à base de pyréthrines synthétiques, d'organophosphorés ou d'hydrocarbures chlorés. Les pyréthrines synthétiques sont plus toxiques que d'autres groupes d'insecticides. Les résidus de cyperméthrine restent toxiques pour les punaises pendant 7 à 10 jours, alors que d'autres composés sont efficaces moins longtemps. En plein champ, une seule application de cyperméthrine a donné de bons résultats contre la punaise terne du pêcher.
