Dataset: Efficacy of Biopesticides in Management of Potato Tuber Moth, Phthorimaea operculella (Zeller), in Three Different Cultivars of Potato under Storage

Pest infestation causes heavy loss to farmers; both in fields and in stores. The study evaluated the efficacy of biopesticides in management of potato tuber moths (PTM) under storage condition. The potato cultivars Khumal Seto-1, Janak Dev and MS-42.3 and biopesticides <em>Bacillus thuringiensis</em>, <em>Acorus calamus</em>, <em>Azadirachta indica</em>, <em>Artemisia vulgaris</em> and a control were used. The cv. Janak Dev had the lowest infestation points per tuber (8.13), emergence of PTM adults (19.77%), physiological loss in weight (26.03%), decay loss (17.89%) and tuber damage score (2.74). The biopesticide <em>Acorus calamus</em> had the least infestation points per tuber (2.56), infested eyes per tuber (0.17), emergence of PTM adults (1%), tuber damage index (2.24), physiological loss in weight (12.11%), decay loss (4%) and tuber damage score (1.36). <em>Acorus calamus</em> had reduced larval mining by 88% and eventually had reduced decay loss by 93% as compared to control. The parameters relating to damage indicated that the cv. Janak Dev was least susceptible among the tested cultivars and <em>Acorus calamus</em> provided the best protection against damage caused by potato tuber moth.

虫害无论在田间还是仓储环节均会给农户造成严重经济损失。本研究评估了生物农药在仓储条件下防治马铃薯块茎蛾（Potato Tuber Moth，PTM）的效果。试验选用了Khumal Seto-1、Janak Dev和MS-42.3三个马铃薯品种，以及苏云金芽孢杆菌（Bacillus thuringiensis）、菖蒲（Acorus calamus）、印楝（Azadirachta indica）、普通蒿（Artemisia vulgaris）四种生物农药与空白对照。其中品种Janak Dev的单块茎侵染点数（8.13）、PTM成虫羽化率（19.77%）、重量生理损失率（26.03%）、腐烂损失率（17.89%）及块茎损伤评分（2.74）均为所有测试品种中最低。在所测试的生物农药中，菖蒲（Acorus calamus）表现最优，其单块茎侵染点数（2.56）、单块茎受侵染芽眼数（0.17）、PTM成虫羽化率（1%）、块茎损伤指数（2.24）、重量生理损失率（12.11%）、腐烂损失率（4%）及块茎损伤评分（1.36）均为最低。与空白对照相比，菖蒲（Acorus calamus）可使幼虫蛀食危害降低88%，最终将腐烂损失降低93%。综合各项损伤相关指标可知，在所测试的马铃薯品种中，Janak Dev的抗虫性最强，而菖蒲（Acorus calamus）对PTM造成的危害具备最优防控效果。
