| dc.description.abstract | Wecreated a detailed model of the Maruca vitrata (F.) and cowpea [Vigna unguiculata
(L.) Walp] system to study the possible evolution of resistance by the insect to transgenic insecticidal
cowpea, which is under development. We focused on population dynamics and genetics in a region
of west Africa. We simulated single-toxin and pyramided (two-toxin) cowpea and emphasized
conservative, worst-case scenarios in our analysis. The results indicate that as long as a pyramided,
transgenic cowpea can be developed, seed saving by farmers and reliance on natural refuge are not
major problems for resistance management. Furthermore, it is possible that one or both toxins in the
pyramid may not need to be high dose for evolution to be delayed signiÞcantly ( 20 yr or 80
generations for resistance to become a concern if transgenic cowpea is deployed in areas where M.
vitrata is endemic). If efforts are made to deploy transgenic cowpea only into the regions where M.
vitrata is not endemic, then there is little to no concern with resistance emerging in the M. vitrata
population. |
