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 enemies from lesser calamints area of origin in Europe that could be introduced in New Zealand as biological control agents.
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.
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.
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 functioning of degraded soils.
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 current crop protection practices and identify the most effective, safe and innovative options to integrate into GIZs programmes in 14 countries.
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.
