 en Laboratory Evaluation of Methanolic Extract of Atlantia monophylla check for this species in other resources (Family: Rutaceae) against Immature Stages of Mosquitoes and Non-target Organisms
N Sivagnaname & M Kalyanasundaram

Abstract

Methanolic extracts of the leaves of Atlantia monophylla check for this species in other resources (Rutaceae) were evaluated for mosquitocidal activity against immature stages of three mosquito species, Culex quinquefasciatus check for this species in other resources , Anopheles stephensi check for this species in other resources , and Aedes aegypti check for this species in other resources in the laboratory. Larvae of Cx. quinquefasciatus and pupae of An. stephensi were found more susceptible, with LC50 values of 0.14 mg/l and 0.05 mg/l, respectively. Insect growth regulating activity of this extract was more pronounced against Ae. aegypti, with EI50 value 0.002 mg/l. The extract was found safe to aquatic mosquito predators Gambusia affinis check for this species in other resources , Poecilia reticulata check for this species in other resources , and Diplonychus indicus check for this species in other resources , with the respective LC50 values of 23.4, 21.3, and 5.7 mg/l. The results indicate that the mosquitocidal effects of the extract of this plant were comparable to neem extract and certain synthetic chemical larvicides like fenthion, methoprene, etc.
