Abstract

An experiment was conducted to study the insect pest complex on cherry tomato under protected condition at Pasighat, Arunachal Pradesh, India during summer 2021-22. It was observed that major pests found to damage cherry tomatoes were Spodoptera litura (Fab.), Helicoverpa armigera (Hb.), and Liriomyza trifolii (Burgess). The peak activity S. litura, with 2.30 larvae per plant, was recorded from May 6th to 12th (19th SMW). The fruit borer also peaked during this period, with one larva per plant. The leaf miner infestation reached its highest at 21.98% in the second week of May. Correlation between weather parameters and larval population of S. Litura was found to be non significant. It was observed that tobacco cutworm is a potential pest on cherry tomato.
