Enhancing the resilience of Bt Cowpea [Vigna unguiculata (l.) Walp] for insect resistance management

Bett, Bosibori Bwari (2016) Enhancing the resilience of Bt Cowpea [Vigna unguiculata (l.) Walp] for insect resistance management. PhD thesis, Queensland University of Technology.


Cowpea is an important food security crop in many countries but its production is constrained by the legume pod borer which can cause yield losses of up to 50%. In this thesis, a molecular approach was used to generate genetically modified cowpea plants which were resistant to this insect pest. Several candidate genes were initially identified and the insecticidal activity of their expressed proteins against the pod borer was tested in insect bioassays. The most promising gene was then used to generate GM cowpea plants, some of which were shown to be resistant to pod borer in insect feeding trials.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
