Expression 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 کاملThe functional response of Aphidius ervi (Haliday)(Hym.: Braconidae, Aphidiinae) to different densities of Sitobion avenae (Fabricius)(Hom.: Aphididae) on two wheat cultivars
The functional response of Aphidius ervi to different Sitobion avenae densities on two wheat cultivars (Sardary and Alvand) was examined in laboratory conditions. Experiments were carried out in test tubes on an F2 lab generation without wheat clusters and also on F2 and F5 generations in pots using wheat clusters. In the tubes, female wasps were exposed to aphid densities of 2, 4, 7, 14, 28, 3...
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...
متن کاملDeciphering the Mechanism of β-Aminobutyric Acid-Induced Resistance in Wheat to the Grain Aphid, Sitobion avenae
The non-protein amino acid β-aminobutyric acid (BABA) can induce plant resistance to a broad spectrum of biotic and abiotic stresses. However, BABA-induced plant resistance to insects is less well-studied, especially its underlying mechanism. In this research, we applied BABA to wheat seedlings and tested its effects on Sitobion avenae (F.). When applied as a soil drench, BABA significantly red...
