Pest Management in Tea Cultivation: Focusing on Helopeltis theivora (Tea Mosquito Bug) and Oligonychus coffeae (Red Spider Mite) in Northeast India

Abstract

Tea (Camellia sinensis) is the world's most popular non-alcoholic beverage, with India being one of the largest producers. In Northeast India, tea cultivation is highly susceptible to damage from insect pests and mites, leading to significant economic losses. Two of the most problematic pests for tea are the Tea Mosquito Bug (Helopeltis theivora) and the Red Spider Mite (Oligonychus coffeae). These pests feed on the tender parts of the tea plant, such as leaves, buds, and young shoots, resulting in decreased yield and quality. This review discusses the biology, damage, and management strategies for both pests, focusing on cultural, mechanical, and biological control methods. Integrated Pest Management (IPM) strategies including the use of natural predators, entomopathogens, and botanical treatments are highlighted as effective and sustainable approaches to mitigate pest-related losses.
