Control Effects against Mosquitoes Larva of Bacillus thuringiensis subsp. israelensis CAB199 isolate according to Different Formulations
Abstract
Among 18 Bacillus thuringiensis isolates with spherical parasporal inclusion from soils, B. thuringiensis subsp. israelensis CAB199 was selected. It was showing over 90% mortality against Aedes aegypti and Culex pipiens moletus. It was confirmed that this B. thuringiensis subsp. israelensis CAB199 isolate also had a insecticidal activity against Culex inatomii that was occurred in the marsh. Because most of mosquito larva were primarily situated or shifted from under- to surface water, we need to select long floating formulations on surface water for controlling mosquito larva. It was tested the pesticidal and control effects in the laboratory and wetland with two formulation types of B. thuringiensis subsp. israelensis, for example, wettable power (WP) and suspension concentrate type (SC). Laboratory test showed that SC formulation type was relatively faster and more effective against 3 tested mosquito species, C. pipiens, Aedes aegypti, and C. inatomii. Otherwise, the control efficacy of SC formulation type was more rapidly appeared against C. inatomii in the wetland.
