Antimetabolic effect of phytohemagglutinin to the grain aphid Sitobion avenae fabricius.
The insecticidal activity of plant lectins against a wide range of insect species have been intensively studied. Understanding the mechanism of the toxicity of lectins is one of the studied aspects. In the present research, the first step was determine the effect of phytohemagglutinin (PHA) on the development, fecundity and mortality of grain aphid. Next, the effect of PHA lectin on the activit...
متن کاملExpression of Potential Resistance Genes to the English Grain Aphid, Sitobion avenae, in Wheat, Triticum aestivum
The English grain aphid, Sitobion avenae (F.) (Homoptera: Aphididae), is a dominant and destructive pest in wheat, Triticum estivum L. (Poales: Poaceae), production regions in China and other grain-growing areas worldwide. Patterns of gene expression of the S. avenae-resistant synthetic wheat line 98-10-35, the S. avenae-susceptible line1376, and their hybrid population, and the differences in ...
متن کاملResistance of Wheat Accessions to the English Grain Aphid Sitobion avenae
The English grain aphid, Sitobion avenae, is a major pest species of wheat crops; however, certain varieties may have stronger resistance to infestation than others. Here, we investigated 3 classical resistance mechanisms (antixenosis, antibiosis, and tolerance) by 14 wheat varieties/lines to S. avenae under laboratory and field conditions. Under laboratory conditions, alatae given the choice b...
متن کاملUnravelling mycorrhiza-induced wheat susceptibility to the English grain aphid Sitobion avenae
Arbuscular mycorrhizal (AM) fungi are root symbionts that can increase or decrease aphid growth rates and reproduction, but the reason by which this happens is unknown. To investigate the underlying mechanisms of this interaction, we examined the effect of AM fungi on the English Grain aphid (Sitobion avenae) development, reproduction, attraction, settlement and feeding behaviour on two natural...
متن کاملLow temperature acclimated populations of the grain aphid Sitobion avenae retain ability to rapidly cold harden with enhanced fitness.
In contrast to previous studies of rapid cold-hardening (RCH), which have investigated the responses of insects maintained under 'summer conditions' (20 degrees to 25 degrees C), this study focuses on the ability of low-temperature acclimated insects to undergo RCH. When the grain aphid Sitobion avenae Fabricus was low-temperature acclimated by rearing for three generations at 10 degrees C, the...
