The effects of a series of phenolic compounds in artificial diets on biotype B greenbugs (Schizaphis graminum) has been evaluated (Levin, 1976, Todd et al., 1971). Z-Caffeic acid (but not -caffeic acid) caused a drastic reduction in growth and inhibited reproduction. Less than 20% of the greenbugs survived on diets that contained vanillic, sinapic, gentisic, or femlic acids (Todd et al., 1971). [Pg.113]

Grindelane normal-labdanes 185 and 188 isolated from Grindelia, Chryso-thamnus, Solidago, and Haplopappus displayed significant antifeedant activity against the Colorado potato beetle (440) and the aphid Schizaphis graminum... [Pg.485]

The order Homoptera used to be considered as a suborder of Hemiptera, so it is appropriate to consider some sterol-related studies with a homopteran of the family Aphididae at this point. In a significant and thorough study, [ Cjsitosterol was converted to radiolabeled cholesterol in the aphid, Schizaphis graminum (22), and no sterol biosynthesis occurred in the aphid or its symbiotes. These results cast doubts on the validity of several previous reports suggesting sterol... [Pg.130]
