Responses of Carpophilus hemipterus larvae and adults to selected secondary metabolites of maize
1990
Dowd, Patrick F.
Selected secondary metabolites produced by maize (Zea mays L.) were tested for effects on larvae and adults of the dried-fruit beetle [Carpophilus hemipterus (L.)] in no-choice and choice assays. Feeding by adults and larvae was significantly reduced by ferulic acid and 6-methoxy-2-benzoxazolinone (MBOA) in no-choice assays. In choice assays, larvae and adults generally preferred diets with trans-cinnamic acid, quercetin, rutin, and thymol, but were repelled by diets with either ferulic acid or MBOA.
