Abstract The tarnished plant bug Lygus lineolaris (Palisot de Beauvois) is a key pest of apples in eastern Canada and, currently, chemical control is the only way to manage this pest. Hyaliodes vitripennis (Say) is a univoltine indigenous predacious mirid and an integral part of biological control programs for apples in certain regions of Quebec. In worst‐case laboratory conditions, thiamethoxam, thiacloprid and acetamiprid were exceptionally toxic to this predacious mirid. The adults were more susceptible than the nymphs. However, the residual toxicity of these neonicotinoids to L lineolaris in orchards was very short‐lived. Because of the short residual toxicity, neonicotinoids should be applied when L lineolaris is at maximum abundance and well before eggs of H vitripennis hatch in late June.
