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:
... The boll distribution characteristics of upland cotton (Gossypium hirsutum L.) cultivars are related to cotton maturity and can interact with environment and management practices to determine yield and fiber quality. The boll distributions of six cotton cultivars under four irrigation levels were compared in 2011 and 2012 on the Texas High Plains. In 2011, a year of severe drought and heat, all cu ...

Abstract:
... The verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), has emerged as a threat to cotton in South Texas, causing boll damage similar to boll-feeding stink bugs (Hemiptera: Pentatomidae). Verde plant bugs were released into caged cotton for a one-week period to characterize the effects of insect density and bloom period of infestation on cotton damage and yield. When plants were in ...

4. Single and Multiple In-Season Measurements as Indicators of At-Harvest Cotton Boll Damage Caused by Verde Plant Bug (Hemiptera: Miridae)

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 ...

Abstract:
... The southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae), is cosmopolitan in distribution and feeds on a multitude of food and fiber crops. It induces abscission of bolls of cotton, Gossypium hirsutum L., and reduces seed cotton yield, gin-turnout, and fiber quality. Also, the bug vectors bacterial and fungal pathogens causing necrosis of the locule and rotting the bolls. Con ...

Abstract:
... The verde plant bug, Creontiades signatus (Distant), has been present in south Texas for several years but has more recently been documented as an economic threat to cultivated cotton, (Gossypium hirsutum L. Our studies over 2 yr (2009 and 2010) and two locations (Weslaco and Corpus Christi, TX) investigated feeding-injury of the verde plant bug to a range of cotton boll age classes defined by bol ...
