Medial prefrontal cortex and Pavlovian conditioning: Trace versus delay conditioning
Autor: Helen Skaggs, Joselyn McLaughlin, John C. Churchwell, Donnie A. Powell
Publikováno v: Behavioral Neuroscience. 116:37-47
Pavlovian eyeblink (EB) conditioning was studied in both trace and delay paradigms in rabbits (Oryctolagus cuniculus) with either medial prefrontal cortex (mPFC) lesions or sham lesions. mPFC lesions of prelimbic cortex (Brodmann's Area 32) retarded

Control of the Green Peach Aphid on Potatoes with Soil Systemic Insecticides: Preplant Broadcast and Planting Time Furrow Applications, 1973–77212
Autor: Donnie M. Powell
Publikováno v: Journal of Economic Entomology. 73:839-843
Systemic insecticides were evaluated as preplant broadcast and planting time furrow applications for control of Myzus persicae (Sulzer) on ‘Russet Burbank’ potatoes. Aldicarb and thiofanox were equally effective for control of aphids with both ap

Area control of the green peach aphid on peach and the reduction of potato leaf roll virus
Autor: W. T. Mondor, Donnie M. Powell
Publikováno v: American Potato Journal. 53:123-139
Peach trees in a 500-mile2 (1295 sq. K) area were sprayed during April and May each year from 1966 to 1969 to control the wingless fundatrix form ofMyzus persicae (Sulzer) after the overwintering eggs had hatched and before subsequent generations of

Reevaluation of the Scab Gnat 1 as a Causative Agent of Deep-pitted Scab of Potatoes 2
Autor: Donnie M. Powell, H. H. Toba, Lee Fox, George Tamaki, H. R. Moffitt
Publikováno v: Environmental Entomology. 5:59-62
Biological and ecological studies showed that the potato scab gnat, Pnyxia scabiei (Hopkins), long considered the causative agent of deep-pitted scab, is primarily a fungus-feeding gnat. It does not feed on healthy tissue of potato tubers and is not

Attempt to Suppress Curly Top and Beet Western Yellows by Control of the Beet Leafhopper and the Green Peach Aphid with Insecticide-Treated Sugarbeet Seed1234
Autor: Donnie M. Powell, G. T. Hagel, B. J. Landis
Publikováno v: Journal of Economic Entomology. 63:493-496
Effective doses of phorate and disulfoton were phytotoxic to seedling sugarbeet plants when they were used to treat the seed, particularly under moisture stress, and doses that were low enough so plant stands were not reduced appreciably did not cont

Endosulfan, Oxydemetonmethyl, and Endrin in Control of the Green Peach Aphid and Suppression of Leaf Roll in Potatoes in Eastern Washington12
Autor: Donnie M. Powell
Publikováno v: Journal of Economic Entomology. 59:1354-1357
Endosulfan, oxydemetonmethyl, and endrin applied in sprays at 1 lb per acre to Russet Burbank potatoes were equally effective in the control of the green peach aphid, Myzus persicae (Sulzer). The incidence of leaf roll in growing plants was reduced s

Control of the Green Peach Aphid and Suppression of Leaf Roll on Potatoes by Systemic Soil Insecticides and Multiple Foliar Sprays123
Autor: Donnie M. Powell, T. W. Mondor
Publikováno v: Journal of Economic Entomology. 66:170-177
Systemic insecticides were applied to the soil on each side of potato seed pieces at planting time and/or were sidedressed into the soil when 75% of the plants emerged, and multiple foliar sprays were applied to obtain seasonal control of Myzus persi

A Comparison of Two Sampling Methods for Estimating Population Trends of Thrips and Mites on Potatoes1
Autor: B. J. Landis, Donnie M. Powell
Publikováno v: Journal of Economic Entomology. 58:1141-1144
A new method for evaluating control of onion thrips, Thrips tabaci Lindeman, and two-spotted spider mites, Tetranychus telarius (L.) (= T. urticae (Koch) ), on potatoes was developed in 1962–63 at Yakima, Washington. The organisms were jarred from
