FIELD ASSESSMENT OF BACILLUS THURINGIENSIS SEROTYPE H - 14 (BACTIMOS W.P.) , ABATE AND FUEL OIL AGAINST ANOPHELES AND CULEX IN SOUTH OF IRAN

Abstract

The Optimum dosage for field application bactimos (W.P.) was determined as 0.04g/m , when efficacy of four concentration of 0.01 , 0.02 , 0.04 and 0.08 gim2 were compared in 1 x I m2 artificial breeding sites. This dosage caused 69.8%, 55.6% and 43.6% anopheline and 83%, 47.8% and 29.7% culicine larval mortality, in 24.48% and 72 hrs post treatment, respectively. Abate and fuel oil were significantly more effective than hactimos (W.P) as they caused 100% , 99.7% and 87.2% anopheline and 100% , 93.5% and 87% culicine lavrval mortality , in 24 hr post treatment , respectivelly. In natural breeding sites Abate, fuel oil and Bactimos (W.P.) caused 100%, 98% and 69% anopheline and 99.9%, 99% and 79.3% culicine larval mortality, in 24 hr post treatment, respectively. The wettable powder formulation of Bactimos was not regarded as a suitable formulation for anopheline control in Southern Iran.
