Insect-resistant GM crops study

Plain text source: 
A recent study by American ecologists has found that GM insect-resistant crops containing a gene from a soil bacterium, Bacillus thuringiensis (Bt), which allows them to produce an insect toxin, are still effective 15 years after they were first commercialised... According to the study, hardly any resistant pests have been found, and the resistance management strategy practised has proven successful... The management strategies are based on two key elements: first, the plants need to produce enough Bt protein to kill pests with low levels of resistance (high dose); second, refuge areas must be planted near Bt crops...
