      More Details Abstract Fulltext PDF

      Funambulus pennanti, the northern palm squirrel preferred wheat in its different forms out of ten cereals and oil seeds offered. It is revealed that the squirrels are selective feeders since out of eleven forms, i.e., whole, cracked, roasted and flour, wheat was found to be most palatable in seven trials followed by bajra (three trials) and jowar once. The addition of vegetable oils, salt and sugar does not enhance the bait acceptance. However, they preferred sugar in comparison to salt, and arachis and sesame oils. Wheat in its whole form is, therefore, recommended for use as a poison base for the control ofF. pennanti. In the absence of wheat, cracked bajra can also be used, which is the next preferred bait. The calorific requirement ofF. pennanti ranges from 16·18 to 34·98 k cal/100 g body weight/day when the bait is provided in single food choice.

      Warfarin was evaluated in laboratory against Indian gerbil,Tatera indica and desert gerbil,Meriones hurrianae. Chronic LD50 for the two species was found to be 4 × 19·1 and 4 × l5·9mg/kg respectively. Feeding for 14 days on 0·025% warfarin treated bait provided complete kill in the gerbils but the poisoned bait was less palatable than the plain bait. A period of 18 and 19 days feeding on 0·025% waifarin bait was found suitable to detect resistance to warfarin amongT. indica andM. hurrianae respectively.

      Brodifacoum, chlorophacinone and coumatetralyl treated pearl millet (Pennisetum typhoides) grains were tested in a desert scrub grassland to evaluate the comparative field efficacy of these three anticoagulant rodenticides. Baits were placed for 10 consecutive days in bait stations in 18 plots of one hectare each in a randomized block design. Per cent reduction in rodent population was calculated by pre and post-treatment active burrow counts, census baiting and live trapping. Results revealed that brodifacoum is significantly more effective than other two anticoagulants. However, analysis of variance revealed significant difference in the estimation of per cent reduction in the rodent population calculated by three methods, the possible reasons for which are also discussed.
