Predator Fauna Associated with Oleander Aphids on Four Milkweed Species and the Effect of Those Host Plants on the Development and Fecundity ofCycloneda mundaandHarmonia axyridis

Autor: Kenneth V. Yeargan, Sarah M. Colvin

Publikováno v: Journal of the Kansas Entomological Society. 87:280-298

The oleander aphid, Aphis nerii Boyer de Fonscolombe, feeds on members of the Apocynaceae family, including several Asclepias species and Cynanchum laeve. Milkweeds alongside and within agricultural crops provide opportunities for natural enemies to

Autor: Sarah M. Colvin, Kenneth V. Yeargan

Publikováno v: Journal of the Kansas Entomological Society. 86:193-205

The oleander aphid, Aphis nerii Boyer de Fonscolombe, feeds on members of the Apocynaceae family. In Kentucky, A. nerii colonizes several Asclepias species and Cynanchum laeve. The prevalence of milkweeds and A. nerii in Kentucky ecosystems allow nat

Seasonal Phenology and Natural Enemies of the Squash Bug (Hemiptera: Coreidae) in Kentucky

Autor: Kimberly B. Decker, Kenneth V. Yeargan

Publikováno v: Environmental Entomology. 37:670-678

The squash bug, Anasa tristis (De Geer), is a major indigenous pest of Cucurbita species across the United States and a vector of cucurbit yellow vine disease. The seasonal phenology of the squash bug in central Kentucky and its natural enemies were

Selection and Evaluation of a Companion Plant to Indirectly Augment Densities of Coleomegilla maculata (Coleoptera: Coccinellidae) in Sweet Corn

Autor: Michael P. Seagraves, Kenneth V. Yeargan

Publikováno v: Environmental Entomology. 35:1334-1341

Coleomegilla maculata (DeGeer), which is a frequent predator of Helicoverpa zea (Boddie) eggs on sweet corn, prefers to oviposit on plants that have glandular trichomes. These plants provide C. maculata eggs a refuge from cannibalism and other predat

DIEL ACTIVITY PATTERNS AND MICROSPATIAL DISTRIBUTION OF THE HARVESTMAN PHALANGIUM OPILIO (OPILIONES, PHALANGIIDAE) IN SOYBEANS

Autor: Kenneth V. Yeargan, Cora M. Allard

Publikováno v: Journal of Arachnology. 33:745-752

Phalangium opilio L. is a polyphagous predator frequently found in agricultural habitats. Although the potential importance of P. opilio's feeding on pests has been recognized, little is known about its activity patterns or its within-plant distribut

Oviposition Behavior ofColeomegilla maculata(Coleoptera: Coccinellidae): Diel Periodicity and Choice of Host Plants

Autor: Kenneth V. Yeargan, Amanda C. Staley

Publikováno v: Environmental Entomology. 34:440-445

Previous research has shown that more Coleomegilla maculata (DeGeer) eggs occur on plants with glandular trichomes than on plants without such trichomes. Those studies also revealed that C. maculata eggs suffer greater predation (mostly cannibalism)
