Insect Pest Resistance: Novel Approach for Detection, and Effective Resistance Management Strategies

Please join us in welcoming Dr. Renata Bažok, Faculty of Agriculture, from the University of Zagreb in Croatia in this exciting guest lecture at NC State. 

Lecture Overview:

The production of the most important arable (maize and potato) and perennial crops (apple) in Croatia are endangered by many insect pests, of which the most important are the western corn rootworm (Diabrotica virgifera virgifera LeConte) (WCR), Colorado potato beetle (Leptinotarsa decemlineata Say) (CPB) and Codling moth (Cydia pomonella L.) (CM). These three pests have shown resistance to insecticides and/or to management strategies. Therefore there is a need for effective resistance monitoring programs that are capable of early detection of resistance and allow the implementation of insect resistance management (IRM) strategies in a timely manner.

Resistance is usually detected through bioassays, biochemical or molecular methods. The need for validated methods of resistance detection in agricultural pests is an imperative. It has been shown that metric properties of insects established by geometric morphometric techniques (i.e., shape analysis) are the first physical characters to change in an organism as they are under the influence of both environmental and genetic factors what makes morphometrics an ideal technique to detect and monitor resistant variants.

Croatian Science Foundation is funding the project entitled MONPERES in which the novel approach for the detection of pest resistance is investigated. The first results proving that morphometric traits could be used for the detection of WCR resistance will be discussed and the plans for future research will be presented.
