| Abstract |
The effectiveness of treating cowpea seeds with petroleum ether, chloroform and acetone extracts of tooth-pick seed extracts against Callosobruchus maculates (F.) was determined. LC50 and LC95 levels were also estimated. Results showed that C. maculates (F.) adults was more sensitive to chloroform extract than other extracts.
Petroleum ether, chloroform and acetone extracts at 7000 ppm concentration gave 92, 100 and 70% kill, respectively after 3 days from treatment All extracts at LC50 and LC95 gave (85.9 and 97.1), (100 and 100) and (98.1 and 100) % inhibition in F-progeny up to 45 days from treatment.
When used LC50 and LC95 for petroleum ether chloroform and acetone extracts of the number of eggs laid were (26 ± 9.7 and 22+7), (12 ± 5.6 and 4 ± 1) and (19.5 ± 7.6 and 17 ± 7) respectively compared with untreated are 101.7 ± 23.
LC95 for all extracts lead to complete protection of cowpea seeds up to 30 days from treatment.
The same concentrations had a determined reduction on germination of cowpea seeds after 75 days from treatment compared with non-treatment seeds
