In the US Southern Plains, locally-adapted annual winter crops support aphid pests and their parasitoids, but variable climatic conditions and host biology alter temporal interactions, and ultimately pest management recommendations. Native parasitoids are well adapted to finding and attacking aphids from fall planting through spring harvest in Oklahoma and Texas, but the impact of these parasitoids is often negligible north of Oklahoma. Furthermore, parasitoid impact is positively correlated with spatial and temporal vegetation-crop diversity. We report on the results of recent and ongoing research which examined how crop diversity influences aphid parasitism and discuss how future studies will investigate observed variation in parasitism throughout the US Southern Plains.
