Accelerating the Morphogenetic Cycle of the Viral Vector Larvae for Faster Larvicidal Bioassays.

Any bioassay to test new chemically synthesized larvicides or phytolarvicides against and more harmful mosquito species, such as s and , which specifically transmit dengue, yellow fever, chikungunya viral fevers as well as Zika virus, or , a vector for malaria and philariasis, requires thousands of well-developed larvae, preferably at the fourth instar stage. The natural morphogenetic cycle of spp., in the field or in the laboratory, may extend to 19 days at room temperature (e.
