Australia: Descubren nuevo método con avispas parasitoides para combatir la mosca de la fruta
That’s according to a two-year project, led by Agriculture Victoria, which has demonstrated that populations of parasitoid wasps can be established in Victoria, at least for the duration of a season.
As populations of Queensland fruit fly (QFly) continue to escalate in Victoria, this will be welcome news for growers in the region, where parasitoid wasps, a natural enemy of QFly have been largely absent.
The research
The project focused on two parasitoid wasp species which both already exist in Australia and prey exclusively on fruit flies – Fopius arisanus and Diachasmimorpha kraussii.
Just a few millimetres long and looking like tiny, winged ants with long antennae, they have an acute sense of smell. They attack QFly by laying eggs either directly into the QFly’s eggs or into developing larvae.
