Essential oil of Siparuna guianensis as an alternative tool for improved lepidopteran control and resistance management practices

Abstract Although the cultivation of transgenic plants expressing toxins of Bacillus thuringiensis (Bt) represents a successful pest management strategy, the rapid evolution of resistance to Bt plants in several lepidopteran pests has threatened the sustainability of this practice. By exhibiting a f...
