Abstract Indoxacarb is a novel oxadiazine pro‐insecticide that has no toxic effects on the adults, fecundity and eclosion of Amblyseius fallacis (Garman), a predacious phytoseiid, or Agistemus fleschneri Summers, a predacious stigmaeid. It is toxic to Hyaliodes vitripennis (Say), a predacious mirid that has been reported from several Quebec orchards where IPM programs are used. The LC 50 for this mirid is about one‐half of the recommended dose (0.054 g AI litre −1 ) of indoxacarb for apple orchards. Following an application, the intoxicated mirids remained motionless as their prolegs and posterior had paralyzed. Twenty‐four hours later, they appeared smaller, shrunken and severely desiccated.
