Assessing the Diversity of Insect Pests of BT and Non BT Cotton Fields from Nalgonda District, Telangana State, India: A Comparative Overview | Chapter 2 | Advanced Research in Biological Science Vol. 5

 The main aim of this phase was to highlight the current position of insect scourge fauna on cotton fields in Telangana's Nalgonda District that were of age with and outside BT. Transgenic Bt cotton that presented one or more insecticidal proteins of Bacillus thuringiensis (Bt) was planted on over 15 heap hectares in 11 countries in 2009 and has donated to a reduction of over 140 million kilograms of poison active additive between 1996 and 2008. As a very selective form of host plant resistance, Bt understand effectively controls any of key lepidopteran pests and has enhance a cornerstone in overall integrated plague management (IPM). Understanding by what method pest species impact understand output demands a thorough understanding of the bug biodiversity of the cotton environment. From July 2018 to January 2019, all the while the kharif cropping season, attempts were attended to evaluate the biodiversity of insect plague on Bt and non-Bt cotton environments. The results indicated that bug pests were recorded from three bug orders viz Hemiptera, Lepidoptera and Orthoptera. A total 4768 things insects on Bt cotton, 5232 things insects on Non-Bt understand fields were recorded by way of sweep net and hand picking. Insect pests were responded to the help of Guide on cotton plague, Regional Agricultural Research Station ANGRAU Warangal and literature. Twenty-two variety on Bt cotton, Thirty-one class on non-Bt cotton were recognized. The result indicates that significant distinctnesses found betwixt the Bt and non-Bt cotton fields. We decided that Bt cotton exerts obvious negative negative imapct on the abundance of bug pests. Various diversity indications were measured.
