Population biology of and the impact of Araneae, on the blackmargined aphid and the yellow pecan aphid (Homoptera:Aphididae) in Texas
(1986)
Field studies were conducted at College Station, Texas in 1984-1986 to examine the population biology of the yellow pecan aphid complex. Populations of blackmargined aphids (M. caryella) were highly variable among pecan ...
The influence of fertilization, phloem restriction, irrigation, microbes, and ethephon on pecan shuck disorders in Texas
(1985)
Shuck disorders are a common production problem of Texas pecan producers. The shuck disorders observed in this study were not caused by stem end blight or shuck dieback. The principal shuck disorders studied were called ...
Characterization and identification of two distinct strains of Watermelon Mosaic Virus-2 affecting cucurbits in Texas
(1985)
Two unrelated viruses, Watermelon Mosaic Virus-1 (WMV-1) and Watermelon Mosaic Virus-2 (WMV-2), cause the major virus diseases of cucurbits in Texas. WMV-1, with a host range restricted to cucurbits, was reported in Texas ...
In-season pecan nut loss in Texas
(1982)
The pecan, Carya illinoensis (Wang.) K. Koch, was subjected to a life table analysis in order to assess the impact of pests and pathogens in various sites and treatment regimes in Texas. Nut clusters were initially tagged ...
Efficacy of the natural enemies of the greenbug, Schizaphis graminum (Rondani), in Texas High Plains grain sorghum
(1984)
The efficacy of greenbug, Schizaphis graminum (Rondani), natural enemies was determined in grain sorghum using mechanical exclusion techniques and paired comparison experimental approaches. Indirect methods of evaluation ...
Isozyme analysis of Sporisorium reilianum populations from sorghum fields in Texas
(1986)
Isozyme analysis was used to assess the genetic variability of Sporisorium reilianum from three field populations in Texas from 1982 through 1984. An effective horizontal starch gel electrophoresis technique was developed. ...
Zonate leaf spot of Sorghum bicolor (L.) Moench, resistance screening and factors influencing Gloeocercospora sorghi propagule germination
(1986)
Zonate leaf spot of sorghum occurs throughout the wet sorghum growing regions of the world (10, 20, 100). The causal fungus, Gloeocercospora sorghi Bain and Edgerton, produces both conidia and sclerotia. The conidia are ...
An assessment of plant resistance to the sorghum midge, Contarinia sorghicola, in selected lines of Sorghum bicolor
(1980)
During a 4-year period, plant resistance in sorghum to Contarinia sorghicola was studied. Experiments were conducted (1) to determine the relative level of resistance to the sorghum midge possessed by selected lines ...
Influence of cotton cultivars on boll weevil (Coleoptera: Curculionidae) behavior and pheromone production
(1986)
Research was conducted to quantify volatile compounds emanating from the flower buds of seven cotton (Gossypium hirsutum L. ) cultivars at two planting location, to determine the influence of the volatiles on boll weevil ...
Developing economic thresholds for rice stink bug management in Texas using dynamic programming
(1988)
Updating of the treatment recommendations used by Texas rice producers' for the management of the rice stink bug (RSB) is the objective of this study. Present treatment recommendations used in Texas and throughout the ...
