Aphids are among the most severe invertebrate pests of crops and cause high economic
losses. The control of aphids by natural enemies is an essential ecosystem service with high …

Landscape ecology has emphasized the key role of spatial heterogeneity as a driver of
ecological processes, which has led to a shift from a patch-matrix to a landscape mosaic …

Abstract Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), reached
damaging levels in 2003 and 2005 in soybean, Glycine max (L.) Merrill, in most northern US …

Aphids, because of their short generation time and low developmental threshold
temperatures, are an insect group expected to respond particularly strongly to environmental …

Agroecosystems contain complex networks of interacting organisms and these interaction
webs are structured by the relative timing of key biological and ecological events. Recent …

Abstract Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is the primary
pest of soybean, Glycine max L., in the north central region. After more than a decade of …

Parasite‐mediated selection can rapidly drive up resistance levels in host populations, but
fixation of resistance traits may be prevented by costs of resistance. Black bean aphids …

Parasitoid virulence and host resistance are complex interactions depending on metabolic
rate and cellular activity, which in aphids additionally implicate heritable secondary …

A climate directly affects the pests, but concomitantly also affects their host plants,
competitors, natural enemies and pest management strategies. As climate is an important …

Naturally occurring predators and parasitoids are known to reduce the abundance of pest
invertebrates in arable crops, yet current treatment thresholds do not account for such a …
