Treating wheat grains treated with chloroform, Acetone and petroleum ether extracts of tooth-pick seed extracts against Sitophilus granarius L. was determined and LC50 and L(.gs levels were estimated. Results showed that S. granarius adults was more sensitive to chloroform extract than other extracts. Chloroform, acetone and pet-ether extracts at 10000 ppm concentration which gave 96, 90 and 92% kill respectively after 3 days from treabnent. All extracts at LCso and L(.gs gave complete inhibition in F1 progeny up to 60 days from treabnent. When using of LC50 and LC95of chloroform and ~ of pet¬ether extracts gave complete inhibition eggs laid, also LC95for pet¬ether extracts, while LC50 for pet-ether and LC50 and LC95for acetone extracts gave significantly reduced in numbers of deposited reaching to eggs 0.83, 2.33 and 0.33 to both extracts, respectively. LC95for all extracts lead to complete protection of wheat grains up to 60 days from treatment, and the same concentrations had a detrimental significant reduction on germination of wheat grains after 105 days from treabnent compared with non-treated seeds.
