Entomologists update definitions to tackle resistance to biotech crops and pesticides | AgroTimes

Resistance to pesticides has now been recorded in nearly a thousand pest species, including more than 500 insects, 218 weeds, and 190 fungi that attack plants. The recorded cases of resistance in insects, mites and other arthropods, which include resistance to multiple pesticides per species, more than doubled from 5,141 in 1990 to 11,254 in 2013. A first step in tackling this growing global problem is establishing a common vocabulary, because the current jumble of terms fosters confusion among scientists in academia, industry and government.
