Antifeedant and repellent effects of neotropical Solanum extracts on drywood termites (Cryptotermes brevis, Isoptera: Kalotermitidae)

Abstract: Antifeedant and repellent effects of two different extracts from native Solanum species Solanum bistellatum and Solanum sisymbrifolium on Cryptotermes brevis were evaluated. The extracts obtained, particularly the dichloromethane extracts and the enriched fraction of sugar esters from S. sisymbrifolium and S. bistellaltum, showed antifeedant and repellent action against the termite. The antifeedant effect of dichloromethane extract from S. sisymbrifolium at the concentration of 25.00mg/mL reached 100%, while the repellent action of the dichloromethane extracts and that of the enriched fraction of sugar esters at the concentration of 1.00mg/mL was higher than 90%. In case of S. bistellatum, the antifeedant effect of the dichloromethane extract and the enriched fraction of sugar esters at the concentration of 25.00mg/mL was 43.29% and 57.46%, respectively. The repellent action of the dichloromethane extracts and of the enriched fraction of sugar esters at a concentration level of 2.50mg/mL was higher than 92%.
