Spatiotemporal distribution of insect populations in heterogeneous landscapes: Problems with sampling, analysis, and interpretation

Carlyle C. Brewster and Erin L. Holden. Virginia Tech, Department of Entomology, 216 Price Hall, Blacksburg, VA

As an informational science, Integrated Pest Management (IPM) requires a complete understanding of the interaction of the insect with its environment at different spatial scales such as the individual plant, field, and entire crop region. Whereas, it is relatively straightforward to interpret insect counts over small spatial scales on plants and in homogeneous fields, this is not easily done for polyphagous insects in large-scale heterogeneous landscapes. We use the satellite remote sensing imagery of the Imperial Valley, CA and the silverleaf (sweet potato) whitefly invasion of the crop system to discuss the difficulties associated with estimating and interpolating insect counts for an entire agricultural region.

Species 1: Homoptera Aleyrodidae (Whitefly)
