Treating wheat grains treated with chloroform, Acetone and petroleum ether extracts of tooth-pick seed extracts against Silvan/us granadus L. was determined and LC₅₀ and LC95, levels were estimated . Results showed that S. panadus 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 treatment All extracts at LC.₅₀ and LC% gave complete inhibition In Fl progeny up to 60 days from treatment. When using of LC_% and LC_9s of chloroform and Lc_% of pet-ether extracts gave complete Inhibition eggs laid, also LC_% for pet-ether extracts, while LC₅₀ for pet-ether and LC_so and LC.₉₅ for acetone extracts gave significantly reduced in numbers of deposited reaching to eggs 0.83, 2.33 and 0.33 to both extracts, respectively. LC_ss for 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 germinabon of wheat grains after 105 days from treatment compared with non-treated seeds.
