Trapping more bugs and thrips

With better insect traps an infestation can be detected earlier. Insects can be captured better and rendered harmless. As a result, less crop protection products are needed to fight the infestation. Earlier this year, the public-private collaboration ‘Visuele attractie van plagen’ (‘Visual Attraction of Pests’) started to achieve optimal monitoring and mass-trapping of pests.

The research focuses specifically on the hairy bugs and the Californian thrips. For the connection with trade, growers from the national committees (Eggplant and Alstroemeria) of LTO Glaskracht Nederland are on the guidance committee.



The tests currently focus on the conditions for researching thrips well and effectively. This takes place in a wind tunnel where temperature, humidity and wind speed can be set. Additionally, various lighting settings are possible. Light source, effect of the color of the capture pad, the role of the glue on the capture pad and the effect of UV are subjects that have been researched.

First results
The first phase of the research has already provided interesting information. Insects clearly observe differently with their compound eyes. If we can fully understand this, it will also be easier to capture them. In the coming period, the tests will be repeated with thrips. Thereafter the research will be continued with the hairy bugs.

Bugs wanted
For the rearing of the bug population, hairy bugs are needed from the trade. If growers have hairy bugs, we will be more than happy to come and collect them. Please contact us if you can deliver hairy bugs.

The research is conducted by Wageningen University & Research in collaboration with the Lincoln University of New Zealand and the Swedish Lund University. Financing takes place via LTO Glaskracht Nederland, Koppert BV and the Ministry of Economic Affairs through the Topsector Tuinbouw en Uitgangsmaterialen. The project is a good example of collaboration for a responsible greenhouse horticulture.
