The aim of the present study is to evaluate the population of some plant oils using Eugenia caryophyllata, Elettaria cardamomum and Citrus sinensis against Coptotermes heimi (Wasmann) at Punjab University, New Campus Lahore, Pakistan. All plants were effectively toxic against C. heimi as 100 % mortality was observed at 62.5, 125 and 250 µl/ml doses within three to four days of exposure. All plant oils extracts proved to be highly repellent to the termites even in the low concentrations. These plant oils can be used for effective termite control being less expensive and biodegradable, hence environmentally suitable. Keywords: Termites, Plant extracts, Repellency |
