Toxicity of selected acaricides on Tetranychus urticae Koch (Tetranychidae: Acari) and Orius insidiosus Say (Hemiptera: Anthocoridae) life stages and predation studies with Orius insidiosus
… and residual toxicity of these acaricides to O. insidiosus; 3) the functional response of O. insidiosus to mobile and egg stages of TSSM, in laboratory and greenhouse studies; 4) the abundance of O. insidiosus relative to TSSM densities in peanut. Direct toxicity of three acaricides to TSSM was …

Bionomics of the anthocorid, Orius insidiosus (Say) in Virginia apple orchards
The anthocorid, Orius insidiosus (Say) is a common polyphagous predator in Virginia apple orchards, particularly in orchards under reduced pesticide programs. The purpose of this research was to contribute to the basic knowledge of the biology and ecology of O. insidiosus in Virginia orchards and …

The behavioral, ecological, and chemical association of Orius insidiosus (Say) with corn silks
The relationship between Orius insidiosus (Say) and corn silk was investigated and an attempt was made to determine the possibility of using O. insidiosus as an augmentative biological control agent against the European corn borer, Ostrinia nubilalis (Hubner) and corn earworm, Heliothis zea …

Ovicidal activity of methomyl on eggs of pest and beneficial insects and mites associated with apples in Virginia
… were highly susceptible to methomyl. Eggs of Orius insidiosus were moderately susceptible. Chrysopa spp. eggs appeared to be unaffected by the material. LC₅₀ values for methomyl on eggs of Platynota spp. L. pomonella, O. insidiosus, Chrysopa spp., and S. punctum were generated. LC₅₀ values for …

Enhancing biotic mortality of the potato leafhopper, Empoasca fabae
… study. Adult Coleomegilla maculata and Orius insidiosus consumed more E. fabae nymphs than adults. In contrast, similar numbers of adult and nymphal E. fabae were consumed by Nabis roseipennis and Chrysoperla carnea.;Adults and nymphs of E. fabae and adults of predatory species were …

Predator-prey interactions involving the soybean aphid (Hemiptera: Aphididae) in Missouri
… The dominant predatory insects observed were O. insidiosus (39.5%) and coccinellids (37.4%). Predators had a significant impact on soybean aphid establishment and population growth; populations exposed to predators never reached economic threshold while populations in cages which excluded …

Leptothrips mali (Fitch): a potentially important predator in Virginia apple orchards
… (Leptothrips mali, Haplothrips subtilissimus, Orius insidiosus, Stethorus punctum, Dereacoris nebulosus, Chrysopa spp.) were monitored during 1977-78 under 3 reduced pesticide programs. The pesticide program with phosalone and Dikarᴿ as its principal components allowed the largest number of …
