Abstract Tomato is one of the most popular vegetables grown in South Asian countries, including India. Introduction of any invasive species to a new environment has always resulted in serious ecological and economical threats globally. One such widely effected invasive pest in tomato cultivation is Tuta absoluta, which was reported infesting tomato fields in India in 2014 for the first time. In order to reduce the over reliance on chemical pesticides, the effectiveness of an integrated pest management (IPM) package including microbial pesticides (Bacillus thuringiensis var kurstaki, Beauveria bassiana), neem products and a chemical pesticide, chlorantraniliprole had been evaluated. Multi-location trials were conducted for two seasons in 2018 and 2019. The findings revealed that the effect of the IPM package in reducing T. absoluta infestation was quite promising in all the experimental trials. The performance of the IPM package was on par with the Farmers' practice (calendar based application of chemical pesticides) in reducing T. absoluta infestation, without any compromise in the marketable yield. The excessive spraying of chemical pesticides in the Farmers’ practice led to an increase in the protection cost at all the experimental sites, which was nearly two times higher than that of the IPM package. Hence, the IPM package can be considered as effective and economical in managing invasive T. absoluta on tomato in South India.

针对入侵的南美番茄潜叶虫 Tuta absoluta 在南印度的综合虫害管理策略的开发和验证

摘要 番茄是包括印度在内的南亚国家最受欢迎的蔬菜之一。将任何入侵物种引入新环境总是会在全球范围内导致严重的生态和经济威胁。番茄栽培中一种如此广泛影响的入侵性害虫是 Tuta absoluta，据报道它于 2014 年首次在印度的番茄田中侵染。为了减少对化学杀虫剂的过度依赖，对包括微生物杀虫剂（苏云金芽孢杆菌、白僵菌）、印楝产品和化学杀虫剂氯虫苯甲酰胺在内的综合害虫管理 (IPM) 包的有效性进行了评估。在 2018 年和 2019 年进行了两个季节的多地点试验。结果显示 IPM 包在降低 T 方面的效果。absoluta infestation 在所有实验中都非常有希望。IPM 包的性能在减少 T. absoluta 侵染方面与农民的做法（化学杀虫剂的日历应用）相当，而不会影响可销售的产量。农户在实践中过度喷洒化学农药导致所有试验点的防护成本增加，比IPM包高出近两倍。因此，IPM 包可以被认为是在印度南部管理番茄上侵入性 T. absoluta 的有效且经济的方法。在可销售的收益上没有任何妥协。农户在实践中过度喷洒化学农药导致所有试验点的防护成本增加，比IPM包高出近两倍。因此，IPM 包可以被认为是在印度南部管理番茄上侵入性 T. absoluta 的有效且经济的方法。在可销售的收益上没有任何妥协。农户在实践中过度喷洒化学农药导致所有试验点的防护成本增加，比IPM包高出近两倍。因此，IPM 包可以被认为是在印度南部管理番茄上侵入性 T. absoluta 的有效且经济的方法。
