Abstract
Helopeltis theivora, also known as Tea Mosquito Bug (TMB), a serious pest of tea, cashew and cocoa. It causes even 100% yield loss if unnoticed. This pest has many alternate hosts from cash crops, vegetables and weeds also. Apart from main hosts, tea mosquito bug survive on a number of non-host plants which facilitate them to sustain throughout the year. Recent literature revealed that every year the host range of this pest is expanding from all over the country. Infestation of Tea Mosquito Bug, Helopeltis theivora was recorded on cotton during 2018. The expanding host range of TMB on economically important plants warrants extensive pest surveillance and intensive monitoring mechanism for designing effective pest management solutions.
