Abstract

: Heliothis armigera is an economically important, polyphagous pest. It feeds on wide range of crops such as tobacco, tomato, cauliflower, peas, maize, brinjal, groundnut, soya bean, cotton etc. It affects the quantitative and qualitative fruit production in more than 157 plant species. Damage is caused by larval stages. Larva bores deeply in the fruit and causes severe damage. The pest Heliothis armigera feeding on five tomato varieties (Pant Bahar, Ratna, Arka Saurabh, Pusa Gaurav and Arka Abha) was analyzed for different growth parameters such as adult emergence, sex ratio and longevity. In the present study, maximum adult emergence (74.33%) was recorded in Pusa Gaurav, followed by Pant Bahar (72.65%) while minimum emergence (62.62%) was noticed in Arka Saurabh tomato variety. The maximum longevity of male Heliothis armigera was recorded on tomato variety Pant Bahar (24.33 days), followed by Pusa Gaurav (19.50 days), Ratna (20.30 days) and Arka Abha (22.65 days) while minimum in Arka Saurabh (18.55 days). The maximum female longevity (31.67 days) was recorded on Pant Bahar while minimum on Arka Saurabh (22.93 days). Observation recorded on tomato varieties indicated that sex ratio was maximum on Pant Bahar (1:1.85) which was at par with Arka Abha (1:1.46), Ratna (1:1.29), Pusa Gaurav (1:1.06) and Arka Saurabh (1:0.98) respectively.

番茄上棉铃虫取食行为对生长发育参数的影响

寄生蜂是一种经济上重要的多食性害虫。它以烟草、番茄、花椰菜、豌豆、玉米、茄子、花生、大豆、棉花等作物为食。它影响超过157种植物的数量和质量的果实生产。损害是由幼虫阶段造成的。幼虫深深钻入果实，造成严重损害。以5个番茄品种(Pant Bahar、Ratna、Arka Saurabh、Pusa Gaurav和Arka Abha)为食，对其成虫羽化、性别比和寿命等生长参数进行了分析。在本研究中，Pusa Gaurav品种成虫羽化率最高(74.33%)，Pant Bahar品种次之(72.65%)，Arka Saurabh品种羽化率最低(62.62%)。雄棉铃虫寿命最长的品种是番茄品种“潘特巴哈尔”(24.33 d)，其次是“普萨高拉夫”(19.50 d)、“拉特纳”(20.30 d)和“阿卡阿布哈”(22.65 d)，最小的品种是“阿卡索拉布”(18.55 d)。雌性寿命最长的是潘特巴哈尔岛(31.67 d)，最短的是阿卡索拉布岛(22.93 d)。番茄品种的性别比最高的品种是潘特巴哈尔(1:1.85)，与阿卡阿卜哈(1:1.46)、拉特纳(1:1.29)、普萨高拉夫(1:1.06)和阿卡索拉布(1:0.98)相当。
