PROBING BEHAVIOUR AND ENZYMATIC DEFENCE OF THE GRAIN APHID AGAINST CEREAL PHENOLICS

ABSTRACT



Probing behaviour of the grain aphid, Sitobion avenae (F.) on sucrose-agarose gels containing o-dihydroxyphenolics was examined using the EPG (electrical penetration graphs) technique. The aphids on diets containing certain o-dihydroxyphenols differed in the mean number of probes and duration of first probe and stylet pathways.

Key words: cereal phenolics, grain aphid, Sitobion avenae, probing behaviour, EPG, polyphenol oxidase.
