.In this review, the mosquito vector borne diseases (VBD) majorly malaria, dengue, filariasis, chikungunya, Japanese encephalitis, Zika were presented to comprehend global disease incidence as control of these transmitting vectors are challengeable globally nowadays. It has been found that malaria affects nearly 500 million people and lymphatic filariasis about 100 worldwide every year. About 2...

Two microbial mosquito larvicides, Bacillus thuringiensis ssp. israelensis (Bti) and Bacillus sphaericus (Bsph), have been shown to be highly effective in controlling mosquito larvae and have been used in larvicidal programs for many years. In exploring other modes of action of these agents, we studied the ovipositional response of Bsph susceptible and resistant Culex quinquefasciatus to aqueou...

Two stable infections of Wolbachia pipientis, wMelPop and wMel, now established in Aedes aegypti, are being used in a biocontrol program to suppress the transmission of dengue. Any effects of Wolbachia infection on insecticide resistance of mosquitoes may undermine the success of this program. Bioassays of Ae. aegypti were conducted to test for differences in response to insecticides between Wo...

In Bacillus thuringiensis subsp. israelensis all of the insecticidal toxins are encoded on a single, large plasmid, pBtoxis. Sequencing of this plasmid revealed 125 potential coding sequences, many of which have predicted functions in gene regulation and physiological processes, such as germination. As a first step in understanding the possible role of pBtoxis in its host bacterium, a survey of...

Three cell lines (A.t. GRIP-1, 2, and 3) were established from Aedes triseriatus (Say) embryonated eggs or neonate larvae and their morphology, growth, karyotype, and isozyme pattern were studied. The isozyme alleles observed in the 3 cell lines also were found in adults of the original mosquito colony. Each cell line differed in enzymatic, morphological, and karyotypical patterns. La Crosse en...
