Over the past few years, Monosteria unicostata, has become a major pest on the Willow and Popolar trees in Tehran. The use of synthetic pesticides is the most common method for controlling this pest. Because of the high capacity of fecundity and daily increasing Monosteria unicostata, studies for toxicity of newer pesticides are necessary.in this research, contact toxicity of new botanical pesticide (Liko®) based on palm oil and biodegradable polymers by concentration of 6000 ppm was examined against the Monosteria unicostata and compared with a conventional pesticide Diazinon 60% by concentration of 2000 ppm in the field condition. Efficacy (%) was estimated by Henderson-Tilton formula. Using Liko, after three days the population of nymph (95.22%), adult (98.19%), using Diazinon, after three days the population of nymph (94.35%), adult (97.61%) were decreased more than Therefore. it is time to focus green chemistry processes and commercialization of natural products as green pesticides on the way to the expansion and application of oils by highly developed formulation technologies.

Key words : botanical pesticide, Liko, date oil
