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

Author:

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 ...

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 ...

Abstract:
... Resistance levels in whitefly, Bemisia tabaci (Gennadius) collections from cotton and sunflower (up to four districts) for five neonicotinoids and two insect growth regulators (IGRs) were investigated for two consecutive years. Based on the LC₅₀s, all collections showed slight to moderate levels of resistance for the tested insecticides compared with the laboratory susceptible population. The data ...

Bemisia tabaci; cotton; cryptic species; cultivars; fecundity; females; gossypol; insect pests; integrated pest management; life history; pest control; population growth; survival rate
Abstract:
... Use of plant secondary metabolic compounds is an important method for insect pest control. In this study, the survival, development, and reproduction of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) MEAM1 cryptic species were compared over two consecutive generations on three cotton cultivars of different gossypol levels. Both cotton cultivar and generation significantly affected the fitness ...

Abstract:
... The abundance and distribution of insect herbivores is determined by, among other things, plant quality and natural enemies. These two factors vary temporally and spatially, subsequently affecting seasonal population dynamics. The relative influence of plant quality and natural enemies on the seasonal dynamics of Bemisia tabaci (Gennadius) was investigated in a three-year field study in cotton. Pl ...

Creontiades; Gossypium hirsutum; bolls; cotton; cultivars; insects; models; pest monitoring; plant damage; plant response; regression analysis; Texas
Abstract:
... The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot provided opportunity to assess if single in-season measurements had value in evaluating at-harvest damage to bolls and if multiple in-season measurements enhanced their combined use. One in-season v ...
