Title:   Geometric, movement and temporal considerations in mate finding in the corn rootworm (Diabrotica spp.) with emphasis on blended refuge
 

Abstract:

The corn rootworm (CRW) is a complex of three species that are very important pests of corn in the mid-western and eastern United States. They are also established in Europe, and their range is continuing to expand. The CRW is a relatively small, defenseless insect that causes damage to corn by destroying the roots of corn plants by their larval feeding. In addition to retarding growth, the damaged corn plants are also prone to lodging (i.e., falling over) which reduces yield by impeding harvest. Much of the corn planted now contains the soil bacterium, Bacillus thuringiensis (Bt), toxin which protects the corn from damage by the CRW. Extensive work is being done to determine ways to preserve the efficacy of the Bt-protected crop in preventing CRW damage. Should the CRW develop resistance, i.e., the ability to survive the Bt toxin, extensive economic damage will result in loss of corn production. There are a number of factors that impact mate finding in the CRW, and thus successful reproduction, including the geometry of refuge placement, ability of the insect to move, and temporal mating pattern.

This talk will explore the statistical dimensions of these phenomena, and reflect on the intense genetic selection pressure, gene flow, genetic "bottlenecking", and "island" biogeography as it relates to the development and establishment of genetically homogeneous resistant populations.

Biography:

A biostatistician in the DuPont Pioneer Hi-Bred Intl Company which is based in Johnston, Iowa, Dr. Stanley received his doctorate from Cornell University, where he studied the application of probabilistic modeling to integrated insect pest management. Over his career at DuPont, he has worked as a research entomologist, eco-toxicologist and statistician. Currently, he is a Senior Research Scientist in Trait Characterization & Development of the Agricultural Biotechnology Department working from home in Lodi, New York. He leads a small group of statisticians and modelers. He was a former Vice President of the DE Chapter of the ASA.
