How insect herbivores alter plant physiology is often unknown, so not surprisingly the interaction of plant resistance with insect injury is similarly uncertain. The recent discovery of a new virulent population of Russian wheat aphid, Diuraphis noxia (Mordvilko), induces responses from resistant wheat that indicates the aphid has found a way to circumvent resistant genes. The avirulent aphid population compared with the new virulent aphid population may give insight into how this insect alters the physiology of a plant. The impact aphid feeding has on physiological responses of resistant (Prairie Red) and susceptible (TAM 107) wheat was documented through the following photosynthetic responses: carbon exchange measurements, carbon assimilation (A-Ci) curves, chlorophyll fluorescence kinetic measurements, invertase activity measurements, and glucose concentrations. Results for these methods will be presented at the meeting.
From Ivan Ayala, Asistant Research, Colombian Oil Palm Research Centre, November 25, 2005 I am a plant Physiologuist research and at the moment I am working in some experiments with relation pest-plant, one with a coleoptera:Chrysomelidae and other with an Acary, I have large experience with gas exnchange, clorphyl fluorescence and enzimaty screning. I wish if is possible to have a PDF file of this paper, (I think that this work has been published). And begin a contact with you
