Abstract: The present investigation was carried out with the aim of estimation of Citronella oil from the Lemon grass and to check the insecticidal effects of citronella as essential oil on the Gram pod borer (H. armigera) as a antifeedants or repellants. The one test with control and second test with 1% Citronella oil was carried out in Laboratory condition with 40 Larva per test. Among those in control condition in normal feeding the 4 Larva (10%) were dead up to 5 days due to some infection. But up to 90% population was be survived. In second test pods treated with Citronella oil used as feeding material. In that test up to 100% population were killed due to the antifeeding and repellent property of the Citronella within 5 days. The mortality percentages at first to 5th days were recorded. Upon that data it was concluded that in future citronella oil is the best way to control the insect population of gram pod borers.
