Mortality and malformation effects of boric acid against larval stage of Aedes aegypti (Culicidae: Diptera)

Author(s): Somia Essa Sharawi
Abstract: Mosquitoes, the disquieting insect, can transmit pathogens more than any other insect, and they can cause fatal diseases to both humans and animals in their environment. With the increasing problem of pesticide resistance spreading in the field, substantial efforts are being made at the international level to develop environmental insecticides to reduce these mosquito populations or limit their potential to transmit disease. In this preliminary study, mortality and malformation effects of seven concentrations (700, 1000, 1200, 1500, 2000, 2500, and 3000 ppm) of boric acid were evaluated against the 4th larval stage of Aedes aegypti after 24 h of exposure. Our results showed that the lethal concentrations (LC50 and LC90) were 1312.49 and 2578.26, respectively. Also, the results showed malformation effects against treated larvae with boric acid compared to the control group. Boric acid is less toxic than synthesized insecticides, and in low concentrations, it causes mortality and malformation effects against larval stages of A. aegypti.
