Research Project: ASSESSING INTERPLANT MOVEMENT OF EUROPEAN CORN BORERS

Location: Corn Insects and Crop Genetics Research

2010 Annual Report


1a.Objectives (from AD-416)
The purpose of this project is to assess the effects of resistance alleles on the frequency, timing, and survival of European corn borer (ECB) larvae after interplant movement.


1b.Approach (from AD-416)
The studies will entail measuring ECB larval movement and survival when larvae are able to move and feed among various combinations of Bacillus thuringiensis (Bt) and nonBt corn plants or various combinations of artificial diet formulated with or without Bt. None of the research conducted under this collaboration involve field release of any insect materials identified in this science plan.


3.Progress Report

Progress was made to determine how first- and second-generation European corn borer injury to blended [growing Bacillus thuringiensis (Bt)-corn and non-Bt-corn plants side-by-side] refuge plants will compare to injury on plants in separate, pure stand non-Bt-corn refuge plantings. Progress was also made comparing the efficacy of growing.
1)pyramided Bt-corn (corn with more than one type of insect toxin in their tissues) next to blended refuge, to.
2)pyramided plants in pure stand plantings. The corn was planted into small replicated plots. The experiment was completed and the report was provided to the cooperator. The ADODR monitored the progress of the project by frequent interactions with the cooperator in the field and via phone calls and email.
