International meeting updates on biological control of invasive pests and weeds

International meeting updates on biological control of invasive pests and weeds

An annual quadripartite meeting of international scientists presented the opportunity for leading experts to update on the classical biological control of invasive pests and weeds including a workshop on eriphyid mites.

The meeting, held at the Edmund Mach Foundation in San Michele all’Adige, Italy, brought together scientists from CABI UK and Switzerland, the Biotechnology and Biological Control Agency (BBCA), Rome, Italy, the United States Department of Agriculture (USDA)  Agricultural Research Service (ARS), European Biological Control Laboratory (EBCL), Montpellier, France and CSIRO, also in Montpellier, who are all involved in the research and development of classical biological control of invasive pests and weeds.

The scientists updated on current and ongoing projects and ran workshops with inputs from the wider European biological control community. There were also invited special guests from the Edmund Mach Foundation, University of Belgrade, Serbia and the University of Bari Aldo Moro, Italy.

The workshops and discussions included:

Eriophyid mites

Eriophyid mites are gaining popularity in weed biological control in recent years. However, several challenges still exist in understanding their basic biology, dispersal and host-finding behaviour to name a few. Professor Radmila Petanović and Dr Biljana Vidović (University of Belgrade) and Prof Enrico de Lillo (University of Bari Aldo Moro) ran a workshop offering solutions to overcome these challenges.

Chemical ecology

Chemical ecology is becoming increasingly important in biological control to elucidate the host-finding and host-choice behaviour of potential agents and to explain ambiguous host specificity testing results. The workshop was run by Dr Gaylord Desurmont (EBCL) who described ongoing work with biocontrol agents for both pests and weeds.

Access and Benefit Sharing (Nagoya Protocol)

The Nagoya Protocol aims to provide a legal framework for the Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization (ABS). This workshop, run by Dr Philip Weyl (CABI), gave an overview of the issues arising for classical biological control through the Nagoya Protocol and the steps CABI has taken to find pragmatic solutions. We emphasized the growing importance to exercise due diligence when it comes to ABS to guarantee that classical biological control remains a viable tool for invasive species management.

New joint projects (BBCA)

Finally, Dr Massimo Cristofaro proposed to the group to collaborate on a common project in order to secure larger grants and suggested the biological control of tree of heaven (Ailanthus integrifolia), which is a target for biological control in the US, but is also becoming increasingly invasive in Europe.  

Dr Hariet Hinz, CABI’s Switzerland Country Director, said, “All in all this was a very informative and useful meeting, including the opportunity to intensify our personal links. We discussed common challenges and explored opportunities for collaborative projects.”

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 Europe’s forests. >>

Biological control of lesser calamint

Lesser calamint is an aromatic perennial herb that has been introduced to New Zealand from Europe. Currently present on the east coast of the North Island, lesser calamint is considered an emerging weed; it is affecting desirable pasture species and having negative economic impacts. CABI is conducting field surveys and searching for natural... >>

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... >>

Integrated weed management in Europe

Weeds are ubiquitous and cause substantial yield losses across all arable and horticultural land. The goal of this European-wide project is to optimise the efficacy, applicability and use of environmentally friendly weed control measures that can replace or complement current chemical control methods. >>

Restoring grasslands of the Qinghai-Tibet Plateau

Halting and reversing land degradation is one of the biggest challenges to meeting the targets set by the Sustainable Development Goals. This project aims to assess the effects of grassland degradation on soil functions on the Qinghai-Tibet plateau and determine whether manipulation of plant functional diversity can accelerate the restoration of... >>

GIZ Crop Protection Baseline Study

Pests and diseases often limit how much smallholder famers can produce. They affect crops both pre and post-harvest by reducing their value or making them unsafe for human consumption. Farmers try to reduce losses through a range of techniques, some of which have human or environmental health impacts. This project aims to understand and report on... >>

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... >>
