Integrated management of Culicoides sp. of domesticated animals

The comparative efficacy of two herbal pesticides containing azadirachtin (10,000 and 1500 ppm) and two biopesticides containing Bacillus thuringiensis var. israelensis and Bacillus sphericus were evaluated for the control of Culicoides larvae. The LC50 values of the above four products were 18.57 ppm, 23.44 ppm, 8433 ppm (0.84%) and 9840 ppm (0.98%), respectively. The herbal products containing azadirachtin proved oviposition deterrent and ovicidal against Culicoides midges. A filler trial was conducted on the utility of guppy fishes (Poecillia reticulata) as larvivorus against Culicoides larvae within 24 hours.
