Abstract

Tomato is an important vegetable crop and cultivated all over the world. The production of tomato is reducing due to the attack of various insect pests such as Liriomyza trifolii. L. trifolii is a very destructive pest and can cause severe economic losses of tomato, Lycopersicon esculentum. Botanicals, Azadirachta indica, and Euclyptus camaldulensis were checked during 2017 under laboratory conditions to check them alone and combine toxicity against second instar larvae of tomato Liriomyza trifolii. Significant differences (P<0.001) were recorded. Highly significant mortality 11.40±0.533c was recorded by the combine treatment of A. indica + E. camaldulensis at 10% concentration followed by A. indica 7.90±1.302ac at 10% concentration. The study concluded both plant extracts (Azadirachta indica and Euclyptus camaldulensis) could be used as effective management strategy to control insect pests especially Liriomyza trifolii in laboratory as well as field conditions.
