- 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:
- ... Alfalfa (Medicago sativa L.) is a highly attractive plant host to Lygus spp. and is used as a trap crop in California organic strawberries to influence the dispersion and dispersal of these pests, particularly Lygus hesperus Knight. The abundance and distribution of Lygus spp. nymphs between two trap crops separated by 50 strawberry rows was analyzed in 2008 and 2010. Nymphs demonstrated a bimodal ...

- Abstract:

BACKGROUND: Chemical pesticides are predominantly used for managing various pests on strawberries in California. Biological control is limited to the release of predatory mites against spider mites. Predominant use of chemical pesticides does not provide complete and satisfactory control of certain pests and interferes with biological control. Microbial control is an unexplored area in Californ ...

- Abstract:
- ... Despite numerous studies examining feeding injury to cotton (Gossypium spp.) caused by different stages of Lygus hesperus Knight, no consistent trends are apparent. One explanation for inconsistencies among previous results is failure to account for important sources of biological variation. Because it was only recently recognized that feeding behavior and injury differed among adults of different ...

- Abstract:
- ... Understanding predator–prey interactions of the arthropod community in any given ecosystem is essential in pinpointing the biological control services provided by natural enemies. Hence, four prey-specific polymerase chain reaction (PCR) assays were developed to analyse the gut contents of the cotton predator community. The four targeted prey included a herbivore/pest, omnivore/pest, omnivore/bene ...

- Abstract:
- ... Despite being an important pest of fruit, vegetable and field crops in the western United States, many aspects of Lygus hesperus Knight (Hemiptera: Miridae) feeding behavior are poorly understood. Lygus hesperus use a cell-rupture feeding strategy. The insects lacerate and macerate host tissues by vigorous movements of the stylets and discharge of lytic salivary enzymes such as polygalacturonases, ...

- Abstract:
- ... Mirid plant bugs (Hemiptera: Miridae) are economically important insect pests of many crops worldwide. The western tarnished plant bug Lygus hesperus Knight is a pest of cotton, alfalfa, fruit and vegetable crops, and potentially of several emerging biofuel and natural product feedstocks in the western US. However, little is known about the underlying molecular genetics, biochemistry, or physiolog ...

- Abstract:
- ... The plant bugs Lygus hesperus, Lygus lineolaris, and Lygus elisus (Hemiptera: Miridae) are major pests of many agricultural crops in North America. Previous studies suggested that females release a sex pheromone attractive to males. Other studies showed that males and females contain microgram amounts of (E)-4-oxo-2-hexenal, hexyl butyrate, and (E)-2-hexenyl butyrate that are emitted as a defense ...

- Abstract:
- ... Management of the western tarnished plant bug, Lygus hesperus Knight, in cotton usually relies on population estimates obtained using the sweepnet. Recent studies indicated adult L. hesperus gender and physiological age influence feeding behavior, within-plant distribution, and injury to cotton. Whether these differences in behavior also influence capture by the sweepnet is not known. We evaluated ...

- Abstract:
- ... Lygus hesperus Knight (Hemiptera: Miridae) is a key agricultural pest in the western United States, but certain aspects of its temperature-dependent development are poorly defined. Accurate models describing the relationships between temperature and development of L. hesperus would facilitate the study of Lygus seasonal population dynamics and overwintering ecology. We used nonlinear biophysical m ...
