Abstract
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 LC9s 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 LCso 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. LCss 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.
