Abstract

Tea industry in India hit a record loss of tea production in 2009-11 due to widespread attack of tea defoliators, looper caterpillar pests of geometrid moths (Lepidoptera) in major tea growing eco-belt of Assam and West Bengal states. This geometrid pest complex has at least four sister species, two each of Biston and Hyposidra ; and a mixed brood of Ectropis sp. The former one was reported as a pest of tea in India since 1911, and later one reported from China and introduced to India; but Hyposidra is a novel tea pest globally, reported recently and that too first from northeast India. Through this article, we attempt to portray the severity of looper outbreak and raised two key questions; viz ., present looper outbreak as an indication of climate change in north-east India? and habitat loss may be the fundamental reason for the primary invasion of looper?

印度东北部茶叶农业生态系统的环形毛虫入侵:气候变化和栖息地丧失可能是原因?

由于在阿萨姆邦和西孟加拉邦的主要茶叶种植生态带，茶叶剥叶虫和鳞翅目害虫(鳞翅目)的广泛袭击，印度的茶叶产业在2009-11年遭受了创纪录的茶叶产量损失。这种几何形状的害虫复合体至少有四个姊妹种，Biston和Hyposidra各两个;前一种自1911年以来在印度被报道为茶叶害虫，后一种从中国报道并传入印度;但最近有报道称，茶蚜是一种全球范围内的新型害虫，而且首次出现在印度东北部。通过本文，我们试图描绘环虫爆发的严重性，并提出两个关键问题;也就是说，目前的钩虫疫情是印度东北部气候变化的迹象?栖息地的丧失可能是环虫初次入侵的根本原因。
