Biological control against the invasive Comstock mealybug in the Swiss orchards
A new invasive pest of particular concern to Switzerland’s orchard industry is the Comstock mealybug, Pseudococcus comstocki. Originating from Asia, the Comstock mealybug was first detected in 2016 in fruit crops of the Swiss canton of Valais. Following its detection, the mealybug has caused significant local economic damage to apricot, pear and apple production, especially during 2018 and 2019. Chemical control is one way of helping to fight the pest but it has produced mixed, and often, insufficient results. Biological control is another method and this project, therefore, aims to develop a sustainable and environmentally friendly, biological control method for the Comstock mealybug.
Proactive biocontrol of Spotted Lanternfly
The spotted lanternfly is an Asian polyphagous pest that feeds on more than 70 plants by sucking the sap out of from leaves, stems and trunks. It was found in Pennsylvania in 2014 and has since expanded its geographical distribution. The damage caused by the pest, its sugary excrement and sooty mold has been devastating for the Pennsylvania wine industry – reportedly causing a 90% grape loss.
Evaluation of fungal pathogens for biocontrol of cat’s claw creeper
Cat’s claw creeper is a vigorous vine native to tropical Central America and northern South America. Introduced into Australia for ornamental purposes, this troublesome liana escaped cultivation and is now regarded as a significant environmental weed.
Managing the invasive threat to Europe’s forests
Over the last few decades, European trees and forests have experienced dramatic losses caused by introduced non-native invasive pests and pathogens. As part of an international project, CABI is developing cost-effective and environmentally friendly tools for the prevention, detection and control of the invasive threats to Europes forests.
