Abstract
The susceptibility of fourth instar larvae of Culiseta longiareolata (Macq. ) to two standard strains of biocontrol bacteria was investigated under lab oratory conditions. Larvae were found to be more susceptible to Bacillus sp haericus (Bs-IPS88) than to Bacillus thuringiensis H14 (Bti-IPS82) at 25 +/ - 1 degrees C at concentrations ranging from 0.003 to 0.004 ppm at 2 and 3 days post-treatment. Statistical regression analysis revealed a significant mortality-concentration relationship for the two bacteria. Larval mortalit y increased significantly as temperature increased from 20 +/- 1 degrees C to 28 +/- 1 degrees C.
