1. Compensation of Lygus hesperus Induced Preflower Fruit Loss in Cotton

Author:
Barman Apurba K.; Parajulee Megha N.

Journal of economic entomology 2013 v.106 no.3 pp. 1209-1217
ISSN:

Subject:
Gossypium hirsutum; Lygus hesperus; bolls; cotton; fiber quality; fruit set; insecticides; insects; irrigation; lint yield; plant damage; rearing; Texas
Abstract:
... A 3-yr field study quantified the compensatory ability of cotton (Gossypium hirsutum L.) to preflower fruit damage by Lygus hesperus Knight in the Texas High Plains under limited irrigation. Experiments were designed to achieve varying levels of preflower fruit loss by augmenting Lygus bug populations using nymphal bugs reared in a laboratory colony. Treatments included 1) three bugs per plant (3P ...

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

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 ...

3. Among-Sampler Variation in Sweep Net Samples of Adult Lygus hesperus (Hemiptera: Miridae) in Cotton

Author:
Spurgeon, D.W.; Cooper, W.R.

Journal of economic entomology 2011 v.104 no.2 pp. 685-692

Subject:
sampling; insect pests; Gossypium hirsutum; insect surveys; plant-insect relations; plant pests; Gossypium barbadense; population density; Lygus hesperus; imagos
Abstract:
... The sweep net is a standard sampling method for adults of the western tarnished plant bug, Lygus hesperus Knight (Hemiptera: Miridae), in cotton (Gossypium spp.). However, factors that influence the relationship between true population levels and population estimates obtained using the sweep net are poorly documented. Improved understanding of these factors is needed for the development and applic ...

cotton; survival rate; Salsola tragus; longevity; artificial diets; Gossypium hirsutum; fruiting; Medicago sativa; instars; weed hosts; Phaseolus vulgaris; alfalfa; green beans; Amaranthus palmeri; population growth; Lygus hesperus; bolls; adults; Texas
Abstract:
... Laboratory studies were conducted to obtain basic biological information of Lygus hesperus Knight (Hemiptera: Miridae) on alfalfa (Medicago sativa L.), pigweed (Amaranthus palmeri S. Wats.), Russian thistle (Salsola iberica Sennen and Pau), green bean (Phaseolus vulgaris L.), artificial diet, and cotton (Gossypium hirsutum L.) square and cotton boll at 27°C. The nymphal developmental duration was ...

Abstract:
... The effects of plant water stress on beneficial and pest insects infesting Deltapine-50 short-staple cotton, Gossypium hirsutum L., and Pima S-7 long-staple cotton, Gossypium barbadense L., were studied in 1993 and 1994 in large replicated field plots in central Arizona. Seasonal densities of eggs, nymphs, or adults of the sweetpotato whitefly, Bemisia tabaci (Gennadius), were reduced 45-69% and 2 ...

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

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 ...
