Influence of Inter-Observer Variation on Insect Scouting Observations and Management Decisions

Autor: Harley G. Raney, Kevin A. Shufran

Publikováno v: Journal of Economic Entomology. 82:180-185

Accuracy of integrated pest management (IPM) scouting observations was assessed by quantifying inter-observer variation and determining its influence on insect management decisions. During 1984 and 1985, the senior author assumed the role of a scout

Autor: R. D. Eikenbary, Harley G. Raney, Floyd Bridgwater, Robert D. Morrison

Publikováno v: Environmental Entomology. 2:859-862

Laboratory populations that served as host for Aphelinus asychis (Walker) were composed of different combinations of the greenbug, Schizaphis graminum (Rondani); the corn leaf aphid, Rhopalosiphum maidis (Fitch); and the yellow sugarcane aphid Sipha

INVESTIGATIONS ON FLIGHT HABITS OF THE PECAN WEEVIL, CURCULIO CARYAE (COLEOPTERA: CURCULIONIDAE)

Autor: R. D. Eikenbary, Harley G. Raney

Publikováno v: The Canadian Entomologist. 100:1091-1095

Research over a 2-year period indicated that female pecan weevils, Curculio caryae Horn, tended to fly higher than males. Male pecan weevils were observed to be clumsy flyers and crawled to the pecan tree more often than females. Significant differen

Intratree Dispersal of the Pecan Weevil 12

Autor: Harley G. Raney, R. D. ElKenbary

Publikováno v: Environmental Entomology. 2:927-930

A study was conducted on the intratree dispersal of Curculio carvae (Horn) in 4 pecan trees about 35 ft high. For 4 consecutive days in August, 66 pecan weevils were released at each of 3 height levels (top = 35 ft, middle = 20 ft, and lowest limbs =

Autor: Harley G. Raney, Kennth J. Starks, Robert D. Morrison, Leon W. Coles, R. D. Eikenbary

Publikováno v: Annals of the Entomological Society of America. 64:169-176

Laboratory studies of Aphelinus asychis (Walker), an imported, internal parasite of aphids, conducted at 5 controlled temperatures showed the preference of the parasite for the aphid species in descending order to be: greenbug, Schizaphis graminum (R

Population Trends of Insect Predators of the Elm Leaf Beetle

Autor: Harley G. Raney, R. D. Eikenbary

Publikováno v: Journal of Economic Entomology. 61:1336-1339

Pyrrhalta luteola (Muller) is one of the more injurious insects attacking Siberian elm trees, Ulmus pumila L., in Oklahoma. The damage is due to the frequent defoliation of trees by P. luteola larvae and adults. Twelve species of insects were found t

Publikováno v: Annals of the Entomological Society of America. 64:864-870

Little research has been published on the importance of spiders as predators in pines in the United States. The objectives of this study were to determine spider populations and their diurnal trends on plantation pines in Oklahoma, to determine relat
