Abstract
Transgenic Bt maize is a potentially important tool against insect pest in the EU and other countries. Bt maize (e.g. MON 810, Bt 11) which carries the Bt gene is highly resistant to larval feeding of European corn borer, stalk borer, and Southwestern corn borer, depending on Bt toxin (δ toxin) production. Effective measures used to fight pests may often have positive side-effects in that they may also contribute to reducing mycotoxin concentrations. A systematic review has been used for the purposes of evaluating the studies on the reduction of aflatoxins in Bt maize. According to five studies, Bt maize has significantly lower concentrations of aflatoxins than non-Bt maize hybrids, only one study has shown no significant effect of Bt maize. Other studies have shown mixed results (four studies). The results of these studies were influenced by the year of sampling or by using maize breeding lines selected for resistance to aflatoxin accumulation.
Highlights
Maize (Zea mays L.), one of the main cereals, is as source of food, forage, and processed products for industry
This study focused on aflatoxins, a group of mycotoxins which are mainly produced by Aspergillus flavus and A. parasiticus (Ehrlich et al 2007)
The present review focuses on current information on Bt maize and the reduction of aflatoxins
