Abstract: The ethanolic crude extract from Solanum xanthocarpum was investigated for its molluscicidal activity against Biomphalaria glabrata, the snail vector of Schistosoma mansoni, and Indoplanorbis exustus, the snail vector of intestinal echinostomiasis and Schistosoma spindale, together with the larvicidal activity against the larvae of Aedes aegypti, mosquito vector of dengue hemorrhagic fever and Culex quinquefasciatus, the mosquito vector of urban bancroftian filariasis. The bioassays were carried out following the methods recommended by the World Health Organization. For molluscicidal activity, the LC50 against Bi. glabrata and I. exustus were reported at 163.85 and 198.00 mg/l while the LC90 were 219.33 and 236.80 mg/l, respectively. Regarding mosquito larvicidal activity, the LC50 against the larvae of Ae. aegypti and Cx. quinquefasciatus were 788.10 and 573.20 mg/l, while the LC 90 were 1,288.91 and 1,066.93 mg/l, respectively. These results suggest a preparation of ingredients from this plant may be used as a biological larvicide for these vectors in the field.
