Abstract
In mosquito control programs, plants secondary metabolites may have the potential to be used as eggs, larvae, and adult, and also prevent insecticide resistance and pollution of the ecosystem. Therefore, the aim of the present study was to validate the effect of naringenin on ovicidal, repellent and insect growth regulating (IGR) properties, and enzymological parameters against Aedesa egypti and Culex quinquefasciatus. Naringenin was investigated for its ovicidal, repellent and IGR properties, and its effect on glutathione s-transferase (GSH), acetylcholinesterase (AChE) and cyclic AMP (cAMP) levels in third instar larvae of Ae. aegypti and Cx. quinquefasciatus. The treatment of naringenin at different concentrations (2, 4, 6, 8 and 10 ppm) produced egg hatchability of 49.2, 18.4, 10.6, 0 and 0 per cent in Ae. Aegypti, while 53.6, 24.22, 9.81, 1.67 and 0 per cent in Cx. quinquefasciatus. The biting protection was 89.1, 95.2 and 98.82, whereas 87.83, 93.20 and 97.23 at 0.5, 1 and 1.5 mg/cm2 concentrations of naringenin for 2 hours in Ae. Aegypti and Cx. quinquefasciatus, respectively. The larvae emergence was notably declined in naringenin treated mosquitoes than control. Further, the GST activity was significantly declined in naringenine treated larva, pupa, male and female adult of selected mosquitoes when compared to control. The AChE activity was significantly declined while cAMP level was notably increased in naringenine treated Ae. aegypti and Cx. quinquefasciatus when compared to control. These findings collectively suggest that naringenin possess all the criteria of insecticides, making it a good candidate for controlling mosquito proliferation.
