Dr Seehausen, a research scientist in risk analysis and invasion ecology based at CABI’s Swiss centre in Delémont, said a biological control agent – the parasitoid Ganaspis cf. brasiliensis – could soon be released to manage the invasive pest in Europe.
The use of DNA to detect a stinkbug invasion proposes a revolutionary advancement in agricultural pest surveillance following the success recorded on a piloted experiment conducted on farms in the USA. These interlopers attack all manner of produce, ranging from fruits to leafy vegetables. However, the adoption of DNA techniques in detecting its early invasion may help to bring its assault to a halt, as opposed to the use of pheromone traps which may only be effective after the pest’s population are pronounced.
The soft-fruit pest Drosophila suzukii, or spotted-wing drosophila (SWD), is particularly difficult to control because of its short generation time and its very broad host range, including many wild and ornamental plants. The pest has been causing damage to fruit crop in Europe as well as North America where damages costing $500million were reported in the USA. The pest arrived in Europe from Asia in 2008, presumably in the larval stage of infested fruit. The fruit fly attacks by depositing its eggs in ripe and healthy fruit where the larvae quickly hatch destroying the fruit.
