T. Paul ; P. Darby ; C. Green ; C. Hodgson ; J. Rossiter | 1996Electrical penetration graphs (EPG's) were used to locate resistance to Phorodon humuli (Schrank) (Homoptera, Aphididae) in hops (Humulus lupulus, Cannabinaceae). Aphids on those hops showing resistance had a much reduced E2 pattern (uptake of p[...]

E. Bernays ; D. Funk | 2000Uroleucon ambrosiae collected from the eastern and the southwestern United States were studied in relation to host-plant probing. In the field, eastern aphids are highly specific on Ambrosia trifida, while southwestern aphids feed on Ambrosia tr[...]

H. Lei ; J. Vanlenteren ; R. Xu | 2001A combination of biological control and host-plant resistance is needed to control greenhouse whitefly, Trialeurodes vaporariorum (Westwood). The high level of susceptibility of several host plants to whitefly, based on their performance on thes[...]

E. Prado ; W. Tjallingii | 1994Aphid salivation in sieve elements and phloem sap ingestion were linked to waveforms in the Electrical Penetration Graph (EPG). Non-viruliferous Rhopalosiphum padi (L.) (Hemiptera, Aphididae) on barley yellow dwarf virus (BYDV) infected wheat co[...]

A. Givovich ; H. Niemeyer | 1995Feeding behaviour of five species of cereal aphids in wheat seedlings differing in hydroxamic acid (Hx) levels, was monitored via electrical penetration graphs (EPG). Aphid species could be grouped as sensitive to the feeding deterrent effect of[...]

J. Klingler ; G. Powell ; G. Thompson ; R. Isaacs | 1998The feeding behaviour, excretion rate, and life history traits of the cotton-melon aphid, Aphis gossypii (Glover) (Homoptera, Aphididae), were measured on a resistant melon, Cucumis melon L., breeding line, AR 5. The site of resistance detection[...]

A. Mayoral ; W. Tjallingii ; P. Castanera | 1996The feeding behaviour of Diuraphis noxia (Kurdjumov) (Homoptera: Aphididae) was electronically monitored on five cereal species (Triticum aestivum L., T. turgidum L., Secale cereale L. and x Triticosecale Wittmack) containing different hydroxami[...]

W. Vangiessen ; D. Jackson | 1998Historically, a bottleneck in the analysis of electronically monitored insect feeding behavior (EMIF) of homopterans has been the conversion of raw waveform data into a format that is easy to analyze. Here we present an efficient method for the [...]
