ABSTRACT
Mosquitoes are on focus worldwide because of its role as vectors for devastating parasites and pathogens causing a threat to millions of people worldwide. Vector-borne diseases in mosquitoes are transmitted by females. However, ineffectiveness of insecticides increases the resistance in mosquitoes. The administration of new vector control strategies against the mosquitoes needs the implementation of microbial insecticides. In this study was commenced to determine the mortality of larvae using gut bacteria as of Eyprepocnemis alacris alacris (Serville, 1838) conflict to larvae laboratory conditions to identify an effective bacteria. The results indicated the existence of larvicidal activity in 106 isolates and were found to appear strongly effective activity in three isolates against Cx. quinquefasciatus. Cent per cent mortality was observed from each of the secondary metabolites. The recorded values of LC50 were 6.66, 7.13 and 7.64ppm and LC90 has been 115.90, 205.73 and 242.59 ppm respectively. The sequencing and phylogenetic analysis confirmed that these 3 isolates were identified as Klebsiella pneumoniae, Enterobacter xiangfangensis and Ochrobactrum intermedium respectively. Our results showed high larvicidal potential effect against to these bacteria. Outcome of these work highlight the alternative use of synthetic chemical pesticides to control mosquitoes.
