The soybean aphid, Aphis glycines Matsumura, has become the single most important
arthropod pest of soybeans in North America. Native to Asia, this invasive species was first …

Coccinellids and aphids interact in a wide range of agricultural and forest habitats and the
value of coccinellid predation for aphid suppression in these systems varies from a minor …

Invasive pest species may strongly affect biotic interactions in agro-ecosystems. The ability
of generalist predators to prey on new invasive pests may result in drastic changes in the …

Coccinellidae function in complex food webs as predators, as consumers of non-prey foods,
and as prey or hosts of natural enemies. Dietary breadth and its implications remain largely …

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

Third and fourth instar Harmoniaaxyridis Pallas larvae feed directly on corn seedlings;
therefore they may be at risk if the seedlings are chemically treated. Neonicotinoids are …

The importance of natural enemies as the foundation of integrated pest management (IPM)
is widely accepted, but few studies conduct the manipulative field experiments necessary to …

Intraguild predation (IGP) occurs when one predator species attacks another predator
species with which it competes for a shared prey species. Despite the apparent …

The harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae) has rapidly spread in
several continents over the past 30 years and is considered an invasive alien species. The …

Characterization of predator-prey interactions is challenging as researchers have to rely on
indirect methods that can be costly, biased and too imprecise to elucidate the complexity of …
