Abstract
Studied the the effect of three concentrations of Al-nbar province isolation BtAN in concentrations (101 x7.35, 102 x7.35, 105 x7.35) and the al-Sulaymaniyah province isolation BtSU in concentrations (101 x5.6, 102 x5.6, 105 x5.6) ml / CFU and Baghdad province isolation BtBA in concentrations (101 x3.56, 102 x3.56, 105 x3.56) ml / CFU were studied and compared with universall standard isolation Bacillus thuringiensis israelensis in concentrations (101 x4.85, 102 x4.85, 105 x4.85) ml / CFU on fourth instar larvae of the mosquito Culex pipiens pipiens and the ratio of mortality was100% for all concentrations of standard Bti isolation while the mortality ratio was 65% in concentration 105 x7.35 ml / CFU in isolation of Anbar BtAN in addition mortality ratio in isolation of Sulaymaniyah was 50% in concentration 105 x5.6 ml / CFU while isolation BtBA did not give any rate of mortality.
