Phenolic acetogenins secreted by rhododendron lace bug,Stephanitis rhododendri Horvath (Hemiptera: Tingidae)


Nymphs of the rhododendron lace bug produce from specialized setae a liquid secretion from which a number of related acetogenins have been identified. Two (2,6-dihydroxyphenyl)-1,3-diketones are the principal components and are accompanied by the corresponding chromones as well as by chromones bearing an additional phenolic oxygen.
