Abstract Flower plantings in agricultural landscapes can contribute to sustainable crop production by enhancing pollination and biological control services. However, selecting plant species that promote multiple ecosystem services is challenging, since plants that favor pollinators may not equally foster natural enemies, and potential trade‐offs, such ...

RAPD PCR Confirms Absence of Genetic Variation Between Insecticide Resistant Variants of the Green Peach Aphid, \u3ci\u3eMyzus Persicae\u3c/i\u3e (Homoptera: Aphididae) [PDF]
Previous allozyme analysis has revealed an apparent absence of enzyme variability in the green peach aphid, Myzus persicae (Sulzer). We are interested in determining the genetic relatedness of individual M persicae clones carrying different numbers of ...

Regional Susceptibilities of Rhopalosiphum padi (Hemiptera: Aphididae) to Ten Insecticides
Rhopalosiphum padi (L.) (Hemiptera: Aphididae) is one of the most significant cereal pests worldwide. Control of R. padi has relied heavily on chemical insecticides. We sampled 12 populations of R.

Maize varieties producing insecticidal proteins from Bacillus thuringiensis (Bt) have become an important component of integrated pest management worldwide. For regulatory approval of such plants, risks to the environment need to be assessed. To make such assessments less expensive and time‐consuming, conclusions drawn from data collected in one region

Abundance of Coccinellids and Their Potential Prey in Field-Crop and Grass Habitats in Eastern South Dakota [PDF]
A rich fauna of coccinellids occurs in eastern South Dakota, but the abundance of some species has declined in association with the establishment of an exotic lady beetle, Coccinella septempunctata (L.) (Coleoptera: Coccinellidae), in the mid-1980s.

Dual role of benzoxazinoids in plant response to combined drought stress and aphid feeding
Benzoxazinoids enhance wheat's defence against aphids and drought stress by triggering callose accumulation, and MYB transcription factors regulate wheat stress response. Abstract Plants produce specialized metabolites like benzoxazinoids (BXDs) to survive adverse environmental conditions and deter herbivory, while insects have evolved mechanisms to ...
