Toxicity of Mexican native plant extracts against larvae of Aedes aegypti (Diptera: Culicidae)
Objective: To evaluate five indigenous Mexican plants [Hippocratea excelsa, Hippocratea celastroides, Argemone mexicana (A. mexicana), Tagetes lucida, and Pseudosmodingium perniciosum (P. perniciosum)] toxicity against the fourth instar larvae of the dengue primary vector, Aedes aegypti (A. aegypti)...

Extracts from seeds of A. mexicana (hexane washing with methanol and acetone) and stem-bark of P. perniciosum (hexane) showed highest toxicity to Ae. aegypti larvae at 48 h post-exposure (LC50 values were 80, 50, and 20 μg/mL, respectively), thus making them potential candidates as biolarvicides.
