Tuta absoluta (Meyrick) is one of the serious pests of tomatoes. This study was conducted to evaluate the effects of some chemical and biological insecticides on T. absoluta. The insecticides tested were diazinon, dichlorvos, chlorantraniliprole, deltamethrin, acetamiprid, imidacloprid, spinosad, abamectin, indoxacarb, Bacillus thuringiensis Berliner, Beauveria bassiana (Balsamo) Vuillemin, and Metarhizium anisopliae (Metschnikoff) Sorokin. Sublethal effects for the most effective insecticides tested, namely, abamectin, spinosad, chlorantraniliprole, and indoxacarb were assessed, and life table parameters were calculated. Chlorantraniliprole had the highest lethal effect on T. absoluta followed by spinosad, abamectin, and indoxacarb. On the other hand, imidacloprid was not considerably effective on T. absoluta eggs. Metarhizium anisopliae was 11 and 518 times more effective on the eggs and newly hatched larvae than B. bassiana and B. thuringiensis, respectively. Chlorantraniliprole, spinosad, abamectin, and indoxacarb affected life table parameters of T. absoluta significantly (α = 0.05). Spinosad had the highest sublethal effect on T. absoluta followed by abamectin, chlorantraniliprole, and indoxacarb. The results revealed that chlorantraniliprole, spinosad, abamectin, and indoxacarb had considerable lethal and sublethal effects on T. absoluta, and if they perform similarly in commercial greenhouses and fields, they would be suitable candidates to be considered in IPM programs for this pest.
番茄潜叶蛾（Tuta absoluta (Meyrick)）是番茄的主要害虫之一。本研究旨在评估一些化学和生物杀虫剂对番茄潜叶蛾的影响。所测试的杀虫剂有二嗪农、敌敌畏、氯虫苯甲酰胺、溴氰菊酯、啶虫脒、吡虫啉、多杀霉素、阿维菌素、茚虫威、苏云金芽孢杆菌（Berliner）、球孢白僵菌（Balsamo）Vuillemin和绿僵菌（Metschnikoff）Sorokin。对测试的最有效杀虫剂，即阿维菌素、多杀霉素、氯虫苯甲酰胺和茚虫威的亚致死效应进行了评估，并计算了生命表参数。氯虫苯甲酰胺对番茄潜叶蛾的致死效应最高，其次是多杀霉素、阿维菌素和茚虫威。另一方面，吡虫啉对番茄潜叶蛾卵的效果不太显著。绿僵菌对卵和新孵化幼虫的效果分别比球孢白僵菌和苏云金芽孢杆菌高11倍和518倍。氯虫苯甲酰胺、多杀霉素、阿维菌素和茚虫威显著影响番茄潜叶蛾的生命表参数（α = 0.05）。多杀霉素对番茄潜叶蛾的亚致死效应最高，其次是阿维菌素、氯虫苯甲酰胺和茚虫威。结果表明，氯虫苯甲酰胺、多杀霉素、阿维菌素和茚虫威对番茄潜叶蛾有显著的致死和亚致死效应，如果它们在商业温室和田间表现相似，将是综合虫害管理计划中针对该害虫的合适候选药剂。
