Abstract Sucking pests are major threat to cotton field crop which cause unbearable losses the yield. Aim of current study was record seasonal dynamics sucking insect including whitefly, jassid, thrips and their natural arthropod predators i.e. green lacewings spiders in plots. The effects surrounding crops on pests’ density predatory efficiency were also recorded. For sampling survey insects, ...

Pecan foliage is attacked by three species of aphids [Monellia caryella (Fitch), Melanocallis caryaefoliae (Davis), and Monelliopsis pecanis Bissell], resulting in damage that can reduce tree nut yield. In this study, we assayed the ovipositional response of the green lacewing Chrysoperla rufilabris (Burmeister) to M. caryella and M. caryaefoliae at high and low aphid densities and the developm...

A concern with Bt-transgenic insect-resistant plants is their potential to harm non-target organisms. Early studies reported that Cry1Ab-producing Bt maize and purified Cry1Ab harmed larvae of the green lacewing, Chrysoperla carnea. Although these effects could not be confirmed in subsequent studies, some authors still refer to them as evidence that Bt maize harms beneficial species. We provide...
