Toxicity of Field-Aged Permethrin-Loaded Attracticides on Choristoneura rosaceana (HARRIS) and Pandemis pyrusana Kearfott (Lepidoptera: Tortricidae) Adult Males and Females Chilean J. Agric. Res.
Curkovic,Tomislav; Brunner,Jay F; J. Brown,John.
Lethal and sub lethal effects were evaluated in the laboratory on Choristoneura rosaceana (Harris) and Pandemis pyrusana Kearfott males exposed to an attracticide loaded with permethrin and aged in the field. The effect of pairing conspecific females with previously intoxicated males was also evaluated. In both species a significantly greater mortality of male moths (≥ 95%) was observed 24 h after exposure to t he attracticide formulation. Likewise, high levels of knock down (≥ 75%) were observed in males of both species 1 h after attracticide exposure. In females, knock down was ≥ 2.5% and mortality ≥ 3.3% after pairing with intoxicated males. Leg autotomy in males was at least 73% in C. rosaceana and ≥...
