Antifeedant and repellent effects of two different extracts from native Solanum species, S. bistellatum and S. sisymbrifolium on Cryptotermes brevis were evaluated. The extracts obtained, particularly the dichloromethane extracts and the enriched fraction of sugar esters from both species, showed antifeedant and repellent activity against the termite. The antifeedant effect of dichloromethane extract from S. sisymbrifolium at the concentration of 25mg/mL reached 100%, while the repellent action of the dichloromethane extracts and the dichloromethane-acetone extract for sugar esters (enriched fraction of sugar esters) at 1mg/mL was greater than 90%. In the case of S. bistellatum, the antifeedant effect of the dichloromethane extract and dichloromethane-acetone extract for sugar esters at the concentration of 25.00mg/mL was 43% and 57%, respectively. The repellent action of the dichloromethane extracts and of the enriched fraction of sugar esters at a concentration level of 2.5mg/mL was greater than 92%.
