Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

open access: yesEcological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

A controversy re-visited: Is the coccinellid Adalia bipunctata adversely affected by Bt toxins? [PDF]

open access: yes, 2012
Background: In 2008/2009, Schmidt and colleagues published a study reporting lethal effects of the microbial Bt toxins Cry1Ab and Cry3Bb on the coccinellid biological control organisms Adalia bipunctata. Based on this study, in concert with over 30 other
