Research Project: ORIGIN, DEVELOPMENT AND POPULATION GENETICS OF STABLE FLIES AFFECTING PASTURED AND CONFINED LIVESTOCK

Location: Agroecosystem Management Research

Project Number: 5440-32000-008-00
Project Type: Appropriated

Start Date: Feb 01, 2005
End Date: Jan 31, 2010

Objective:
To gain a better understanding of stable fly population dynamics by elucidating their genetic structure throughout North America. To identify and characterize stable fly larval developmental sites and correlate larval production with adult population dynamics in relation to season, climatic variables and cultural practices. To determine the relative contributions of overwintering and migration to early season, colonizing, stable fly populations.

Approach:
Methodologies to achieve the objectives include: Development of genetic markers and application of population genetic analyses to understand the structure of stable fly populations and the roles of migration and genetic drift in maintaining the observed structure. Surveys will be conducted to identify stable fly larval developmental sites. The production and phenology of developmental sites will be determined. Production will be correlated with adult populations to identify primary contributors to pest fly populations. Surveys will be conducted to identify stable fly overwintering habitats. Overwintering habitats will be characterized. Artificial overwintering habitats will be developed to study the environmental limits of overwintering stable flies.
