Live wood eating termites are responsible for considerable damage to young and mature teas throughout North-East India. Termite infestation leads not only to economic loss but also to the failure of several years of effort to grow tea plants. This study reveals the efficacy of various non-chemical approaches to control the termite problem in Assam tea plantation. Two multiplication field trials consisted of twelve non-chemical treatments were conducted following randomized block design (RBD) with three replications. The trials revealed that Metarhizium anisopliae , Beauveria bassiana , Heterorhabditis indica and Ipomea carnea were effective in controlling the termites in tea compared to the check (thiamethoxam, a commonly used chemical pesticide against termites in conventional tea estates) as well as to control (untreated- water spray for both organic and conventional tea estates). Along with these non-chemical treatments, an integrated management package for termite control is discussed.

印度东北部茶园食木白蚁的非化学综合管理包

吃活木头的白蚁对整个印度东北部的年轻和成熟茶造成相当大的破坏。白蚁侵扰不仅会导致经济损失，还会导致多年种植茶树的努力失败。这项研究揭示了各种非化学方法在控制阿萨姆茶园白蚁问题方面的功效。按照随机区组设计 (RBD) 进行了两次繁殖田间试验，包括 12 种非化学处理，重复三次。试验表明，绿僵菌、球孢白僵菌、籼型异形线虫和红豆角与对照（噻虫嗪、一种常用的化学杀虫剂，用于对抗传统茶园中的白蚁）以及控制（有机和传统茶园的未经处理的水喷洒）。除了这些非化学处理外，还讨论了用于白蚁控制的综合管理包。
