Скачать или смотреть BioControl: Multivoltine midge laying eggs on Acacia cyclops

"In 2003, a multivoltine midge (Dasineura dielsi) that induces galls on the ovary of its host , was introduced from Australia for the biological control of Acacia cyclops in South Africa. It spread extremely rapidly and now colonizes virtually all mature Acacia cyclops in the region. By inducing the gall it stops the flower from forming and hence drastically reduces the seeds produced. Extensive studies are undertaken prior to the release of biological control agents in South Africa and all indications are that D. dielsi will be of no significance on any species other than A. cyclops."
