Seasonal Distribution of Stink Bugs Relative to Landscape
| Problem: | Spatial and temporal patterns of stink bug populations in non-crop habitats and mechanisms influencing these patterns are poorly understood. Consequently, such data are difficult to interpret in a meaningful fashion. Relation of capture patterns in cotton and non-cotton habitats, both during and between cotton production seasons, to biogeographical features and meteorological factors would provide an improved framework for interpreting ecological management implications of these populations. |
| Objective: | Develop a geographic information system to examine seasonal changes in the spatial distribution of stink bugs relative to plant and environmental factors. |
| Approach: | Stink bugs will be sampled by sweep nets, KISS blower samplers, and by visual inspection in cotton, soybeans, sorghum, corn, other crops, and uncultivated vegetation. Plant type, plant growth stage, climatic factors, soil properties, and proximity to bodies of water will be classified from ground-based observations and aerial remote sensing imagery. |

Significant Impact:
|
These data will be incorporated into a geographic information system for use in a decision-support system for management of stink bugs in cotton and adjacent non-cotton habitats. |
