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.

Biological control of the Spotted wing Drosophila – Drosophila suzukii

Drosophila suzukii Matsumura (Diptera: Drosophilidae), a fruit fly from East Asia, is now a serious economic pest of soft fruits and berries across Europe, the Americas and North Africa. In this project we are focusing on finding natural enemies (parasitoids) of the pest to introduce into Europe. This involves surveys for parasitoids where it originated and experiments in quarantine in Switzerland to investigate their taxonomy, performance and specificity.

Beneficial nematodes to control rootworms in European maize production

The western corn rootworm is a major invasive maize pest in North America and Europe. Control options become more and more limited as problematic pesticides are being phased out. 10 years of joint efforts in research and development by academic, legislative and commercial partners have led to a nematode-based biological control solution for this destructive maize pest. Mass-produced beneficial nematodes Heterorhabditis bacteriophora are now available as a commercial product.

Research, rearing and collection services on corn rootworms

The western corn rootworm is a destructive pest of maize. Most damage is caused by larvae feeding on the roots, which becomes apparent when plants lodge. Drawing on some 15 yearS experience as a research and development partner on corn rootworms, CABI has become a key service provider for field surveys, laboratory and field research on basic ecology and management of the pest, rearing including supplying eggs for research, and writing support.

Insects as a source of protein

Global demand for animal-sourced foods is accelerating. Fishmeal and crops such as soya are key ingredients in animal feeds but are not ecologically or economically sustainable. Insect protein presents a viable alternative. The PROTEINSECT project is exploring fly larva (maggots), which are nutritious and can be mass produced at low cost, as animal feed. It will develop and optimize maggot production systems, determine safety and quality criteria and evaluate the performance of protein extracts.
