The study focuses on the biological activity of Euphorbia guyoniana (Euphorbiaceae) extract, on larvae L5 and adults of Schistocerca gregaria. The Larvaes L5 and adults of S. gregaria made in presence of cabbage leaves sprayed with the extract of the leaves of E. guyoniana lost respectively 26,93 % and 33,09% of their initial weight. Meanwhile, the larvae L5 fed on leaves of cabbage leaf extract of E. guyoniana could not do their fledging Moreover, larval mortality of 100% was noted after the…

Bioactive triterpene derivatives from latex of two Euphorbia species.
Analysis of the antifeedant and toxic effects of 23 semisynthetic terpenoid derivatives obtained through chemical modifications of the major components of Euphorbia resinifera and E. officinarum shows that Sf9 cells were more sensitive to the active compounds than CHO cells, and that the C-3 hydroxyl is not essential for the IGR effect.
