Insecticidal activity of artemisia sieversiana Ehrh. plant extract against white grub (Scarabaeidae: Coleoptera)
June beetles larva, commonly known as white grub, feed on the roots of many herbaceous and woody plants. White grub is an important agricultural crop pest found in agro-climatic conditions of Gilgit Baltistan. Insecticidal activity of Artemisia sieversiana Ehrh. Plant crude extracts prepared in three different solvents (Acetone, Ethanol and P. ether) against white grub was studied in Laboratory. Bioassay for repellency and residual toxicity of crude extracts carried out with three serial doses (1%, 3% and 5%). The results showed that maximum repellency (98.30%) was observed at 5% extract in Ethanol after 3 hours exposure. Maximum mortality (97.00%) in white grub was recorded at 5% extract in acetone after 72 Hr of insect exposure. The results revealed that A. sieversiana Ehrh. Has dual properties repellency and residual toxicity and can be used for eco-friendly management of white grub replacing chemical insecticides.
