    Development of integrated rodent pest management module for commensal situations
    (Punjab Agricultural University, Ludhiana, 2022) Komalpreet Kaur; B.K. Babbar
    Rattus rattus is a predominant pest in commensal situations. There is a need to develop a rodent management module for commensal situations for long term solution to the problem. During present study, andrographolide based baits were tested against house rats under laboratory for their toxic and antifertility effects. However absence of toxic and minor antifertility effects of treated baits indicated need to increase the bioavailability of andrographolide in bait. Experiments were also conducted to study the efficacy of different management methods at selected locations for controlling rodent population either by single method/product or by integrating different rodent pest management methods. Testing of a repellent based formulation (RBF) revealed that single treatment with 5 packets (25g each) is effective to reduce upto 60-80% rodent population for 18-36 days in airtight/enclosed conditions. It was also observed that rats do not develop habituation against RBF. It can be successfully used in situations where rats develop trap and poison bait shyness. Cost of one packet of RBF is Rs 11/-.Double trapping for four days was found to be effective to reduce 45 to 80% rodent population in an area ranging from 135 to 200 sq.ft. for three months with six traps at a cost of Rs 300/- only. Rodent proofing provided 82.46-95.29% reduction in rodent activity during the observation period of 96 days after proofing. Integration of trapping with rodent proofing under conditions where complete rodent proofing is not possible, provided long term solution to the problem. Neem seed and andrograppholide based NSA bait was found to be effective as toxic and antifertility agent even under real commensal situations. Overall these results indicated that integration of rodent proofing with trappingranked 1st followed by rodent proofing, RBF, trapping and integration of trapping with RBF ranked 5th in managing rodent population under commensal situations
