1. Costs of Lygus Herbivory on Cotton Associated with Farmer Decision-Making: An Ecoinformatics Approach

Author:

Gossypium hirsutum; Lygus hesperus; abscission; buds; commercial farms; cotton; data collection; decision making; defoliants; farmers; farmers' attitudes; herbivores; observational studies; pest management; plant growth; plant growth substances
Abstract:
... Because the farmer is typically excluded from the experimental research setting, experimental research may face challenges in evaluating pest management tactics whose costs and benefits hinge on farmer decision-making. In these cases an ecoinformatics approach, in which observational data collected from the commercial farming setting are “mined” to quantify both biological variables and farmer beh ...

2. Plant responses to insect herbivore damage are modulated by phosphorus nutrition

Author:
Forbes, Andrew A.; Rosenheim, Jay A.

Entomologia experimentalis et applicata 2011 v.139 no.3 pp. 242-249
ISSN:
0013-8703
Subject:
Gossypium hirsutum; Lygus hesperus; Lygus lineolaris; abscission; flower buds; flowering; lint cotton; lint yield; nutrition; phosphorus; phytophagous insects; plant response; surveys
Abstract:
... Interactions between plants and their herbivores are often multidimensional, complicating interpretation of herbivore-impact studies. A previous study, directed toward understanding variation in incidences of flower bud abscission among cotton plants attacked by Lygus plant bugs, revealed an unanticipated correlation between levels of phosphorus nutrition and the propensity of plants to abscise de ...

3. Estimating the Impact of Lygus hesperus on Cotton: The Insect, Plant, and Human Observer as Sources of Variability

Author:
Rosenheim, J.A.; Steinmann, K.; Langellotto, G.A.; Zink, A.G.
Source:
Environmental entomology 2006 v.35 no.5 pp. 1141-1153
ISSN:

Subject:
Lygus hesperus; host plants; Gossypium hirsutum; cotton; feeding behavior; crop damage; plant response; abscission; sampling; population density; California
Abstract:
... Unexplained variation in the relationship between herbivore densities and the short-term appearance of crop damage is sometimes observed in pest management. Here we used a field survey of commercial cotton fields and a linked questionnaire for cooperating pest control advisors to document the existence of such unexplained variation in the impact of the western tarnished plant bug, Lygus hesperus, ...

4. Cotton square damage by the plant bug, Lygus hesperus (Hemiptera: Heteroptera: Miridae), and abscission rates

Author:
Leigh, T.F.; Kerby, T.A.; Wynholds, P.F.
Source:
Journal of economic entomology 1988 v.81 no.5 pp. 1328-1337
ISSN:

Subject:
Gossypium hirsutum; plant damage; Lygus hesperus; population density; field experimentation; abscission; California
Abstract:
... Numbers of Lygus herperus Knight per 50 net sweeps and numbers of abscised and lygus bug damaged squares per cotton plant terminal were counted weekly. Square abscission and square damage showed a high positive correlation with L. hesperus numbers (r = 0.92, n = 7, for week of count and r = 0.69, n = 63 for June through July) and with square age (r = 0.96, n = 20); fruit set on first and second sy ...
