A Laboratory based study on the Larvicidal effects of Aquatain, a Monomolecular Film and Mousticide? [Trypsin Modulating Oostatic Factor [TMOF-Bti] formulation for the control of Aedes albopictus (Skuse) and Culex quinquefasciatus Say in Pakistan

摘要

Experiments were performed to test the efficacy of Mousticide., a combination of two natural substances Trypsin-modulating oostatic factor [TOMF] Bacillus thuringiensis israelensis [Bti] and Aquatain, against larval late third early four of Aedes albopictus and Culex quinquefasciatus under laboratory conditions. The results of the study have established the effectiveness of the products tested. The aquatain has maximum mortality trend of Aedes albopictus and Culex quinquefasciatus by different treatments (0.017 ml, 0.035 ml, 0.070 ml and 0.14 ml) at their maximum concentration (0.14 ml) after 1 hour was (20% and 17% respectively) and after 12 hours (100%). The TMOF -Bti has maximum mortality trend of Aedes albopictus and Culex quinquefasciatus by different treatments (10 mg, 25 mg, 40 mg and 100 mg) at their maximum concentration (100 mg) after 1 hour was (10% and 12% respectively) and after 24 hours (100%). All the concentrations of Aquatain and TMOF-Bti caused high mortality (95-96%) within 12 hour of treatment and 100% mortality until 24 hours after treatment. Our results have further revealed that Aquatain is more effective as compared to TMOF -Bti in controlling larval stages of test mosquitoes.
