    , USA, in 1997 and 1998. Weed management systems that allowed more weed escapes typically had higher insect population densities. However, systems with fewer weeds seemingly were preferred by potato leafhoppers. Bean leaf beetles and potato leafhoppers showed preferences for certain soyabean varieties, but these effects were attributed to soyabean plant heightplant heightSubject Category: Properties

    . These findings indicate that although the transgenic soyabean varieties did not strongly affect insect populations, weed management systems can affect insect populations in soyabean. However, this impact is likely related more to weed suppression effectiveness than to a direct effect of the herbicides on the insects.
