摘要: Laboratory and semifield bioassays were conducted to determine the life-stage activity of insecticides for controlling cranberry fruitworm, Acrobasis vaccinii Riley (Lepidoptera: Pyralidae), a key lepidopteran pest highbush blueberry, Vaccinium corymbosum L. The organophosphates azinphosmethyl phosmet, pyrethroid esfenvalerate, carbamate methomyl lethal all life stages. neonicotinoids thiacloprid acetamiprid demonstrated strong larvicidal ovicidal but somewhat weaker adulticides than conventional broad-spectrum compounds. Bacillus thuringiensis, indoxacarb, emamectin benzoate shown control A. vacinii primarily through their activity. Spinosad was toxic stages, including eggs laid on top residues those that treated topically, short lived. growth regulators pyriproxyfen novaluron had when limited Tebufenozide not directly eggs, activity, ovilarvicidal topically applied eggs. Azinphosmethyl, thiacloprid, egg parasitoid Trichogramma minutum Riley. In contrast pyriproxyfen, benzoate, methomyl, novaluron, spinosad did negatively affect survival T. within These results help inform ongoing development integrated strategies insect management in blueberry.
