With this project we aim to develop new approaches in biological pest control with generalist predators that can contribute to the reduction of pesticide use in greenhouses. Ornamental crops in Dutch greenhouses experience increasing problems with "old" established and "new" invasive thrips species. The most noxious species is western flower thrips Frankliniella occidentalis, which is also an efficient vector of plant viruses. Current new invasive species are Thrips setosus and Echinothrips americanus. Biological control of these thrips species is often not successful, mainly because potential natural enemies did not establish well in crops. This can be caused by the lack of suitable oviposition sites, food sources or a possibly mismatch between habitat preferences of the predators and pests. In this project we will evaluate the potential of new species of anthocorid predatory bugs as biological control agents of old and new thrips species that occur in Dutch greenhouse ornamental crops and develop tools to optimize their control efficacy. Studies include population dynamical greenhouse trials, spatial dynamics of predators, habitat preferences and manipulation, mixed diet effects, intraguild predation and predator-mediated food web interactions. The project is focusing on both the fundamental aspects of biological control and on finding practical biological control solutions for growers.

- An MSc degree in Biology, Plant Sciences or a related discipline.
- Proven interest in insect ecology and biological pest control.
- Interest in fundamental research.
- Experience with experimental research on insects.
- Excellent research skills.
- Experience with statistical data analysis.
- Ability to work independently.
- bility to work in a multidisciplinary team.
- Proficient in English, written and spoken.
- Organizational and communication skills.
ConditionsWe offer a full-time position (38 hours), initially for 1 year after which a go/no go decision will be taken on extension with another three years. Gross salary per month € 2266,- in the first year rising to € 2897,- per month in the fourth year, for a fulltime appointment. The candidate will be based at the Business Unit Greenhouse Horticulture in Bleiswijk and partly at the Laboratory of Entomology in Wageningen.
