| dc.description.abstract | Six different concentrations of NSP (2, 4, 6, 8, 10 and 12%), nine different doses from stock solution of NSAE (0.2, 0.4, 0.6, 0.8, 1.0, 1.5, 2.0, 2.5 and 3.0 ml) and six different doses from NSO (0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 ml) were tested under laboratory condition to determine the effective dose with repellent effect against R. rattus. Results revealed antifeedant/ secondary repellent effect with the all doses and there was non-significance difference in antifeedant index (AI) among doses, therefore for the further studies, two dose each of NSAE ( 0.2ml and 2ml) and NSO (0.1ml and 0.6 ml) were selected. Testing of existence of primary effect revealed that rats avoided all the treated baits four first one to four hours after exposure. After that rats developed habituation to primary/olfactory repellent effect and started eating treated baits but consumption of treated baits remained low. Rats were not habituated for secondary repellent effect with the effective doses of NSAE (2 ml) and NSO (0.6ml) upto experiment period of 30 days. Six formulation (F1 to F6) were prepared using effective doses of NSAE and NSO and were tested under simulated storage conditions and in grain stores. Result revealed potential of F3 and F4 as repellent in preventing rodent damage for considerably long time as compared to other formulations tested. For using antifertility property of neem, seven different formulations (F7 to F13) were prepared using neem seed alcoholic hexane extract (NSAHE). As consumption of F11 was maximum, therefore antifertility effect was recorded in rats fed on F11 as well as in rats given oral dose of NSAHW. Results revealed potential of neem seed alcoholic hexane extract and its F11 formulation in reducing reproductive potential of rats. However there is need to further increase the acceptance of F11 based bait. | en_US |
