Article Synopsis
- - Researchers investigated a high-throughput method to assess how different winter wheat varieties respond to harmful aphids, Sitobion avenae and Rhopalosiphum padi, focusing on both antixenosis (host preference) and antibiosis (impact on aphid survival).
- - The study found significant variations in aphid behavior, with some wheat varieties attracting four times more aphids than others, and established that phloem feeding patterns correlated with resistance traits; traditional methods using detached leaves proved ineffective for accurate results.
- - The findings emphasize that direct observation of aphid settlement on seedlings is a more effective approach for screening, allowing for faster identification of wheat varieties with potential genetic resistance against aphid pests.
Wheat is an economically, socially, and nutritionally important crop, however, aphid infestation can often reduce wheat yield through feeding and virus transmission. Through field phenotyping, we investigated aphid resistance in ancestral wheat Triticum monococcum (L.).

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 naturally susceptible varieties Triticum aestivum (L.) variety Solstice and T.
