| dc.description.abstract | Neem extracts have strong Insecticidal, repellent and antifertility effect. Seven different doses of NSA extract (1.5, 3.0, 4.5, 6.0, 7.5, 9.0, 9.5 ml out of 25 ml stock) mixed in bait were tested against male bandicoot rat, Bandicota bengalensis in bi-choice feeding tests. Results revealed antifeedant effect with all treated baits and there was non-significant difference among treated baits. Therefore only three different doses (1.5, 7.0 and 9.0ml) were selected for further studies. Testing of existence of primary repellent effect revealed that rats avoided all the treated baits for first five hours after exposure. After that rats developed habituation for primary/olfactory repellent effect and started eating treated baits which might had caused gastrointestinal malaise in rats resulting in development of secondary repellent effect among rats. However rats were not habituated for secondary repellent effect with all the selected doses of NSA extract upto experimental period of 30 days. Therefore for field application, formulations F1 and F2 were developed using NSA extract (7.5-9.0ml). These formulations were tested under simulated field condition. Results revealed potential of F2 in preventing rodent damage for considerably long time as compared to F1. To use the antifertility property of neem seed, neem seed alcoholic hexane (NSAH) extract and its formulations as baits (F3 –F7) were developed and fed to rats. Consumption of F7 bait was maximum. Results revealed potential of NSAH extract and its F7 bait in reducing reproductive potential of rats. However there is a need to increase the acceptance and application rate of F7 bait under field conditions. | en_US |
