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
