Description

Main research question/goal

In Flemish ornamental horticulture, in ordinary gardens, in public green areas, and on strawberry and small fruit companies, more and more damage is being suffered because of the weevil Otiorhynchus sulcatus (family Curculionidae) and related weevil species. To date, there is still no optimal control method available. That is why problems with this beetle and other snout beetles have been dragging on for years. The main objective of SURVEY SNUITKEVERS is the inventory and monitoring of the vine weevil and related plant harmful weevils in the ornamental plant and tree nursery to map the diversity, the monitoring technique and the phenology of the common beetles in order to determine the best possible timing of control as well as an integrated control strategy.


Research approach

We make an inventory of the most dominant weevils in floriculture in Flanders. We are looking for ways to identify them morphologically. We determine the most suitable monitoring technique: is it pitfall traps, soil traps with attractant, attractive host plants (attractants), bottom adhesive strips, easily monitored shelters or a visual inspection of the crop? We map in detail the life cycle and phenology of the dominant weevils. We process the results in communication and in useful applications to the sector, including through the Pest Alert System.


Relevance/Valorisation

From the in-depth monitoring, we expect to obtain very valuable applications that will reduce the damage incidents in floriculture and landscaping. Determination of a better (best) observation technique as well as better knowledge of which is/are the most damaging (most important) snout beetle(s). The whole picture around the vine weevil and related species becomes clear: species diversity, phenology and knowledge of their host plants, attraction plants and natural enemies. The valorization process may already take place partly during the course of the project, namely the target group of growers. The results are given an almost immediate application in practice by disseminating the knowledge via the current Monitoring and Pest Alert System.
