Description

Main research question/goal
What is the behaviour of the gall mite Cecidophyopsis malpighianus? How and where does it breed? When does it migrate? Where does it take shelter? These answers may help to develop an adequate and sustainable control method (IPM or integrated pest management) for C. malpighianus. Gall and rust mites are minute mites, some of which can cause large-scale crop damage. On pruned Laurus nobilis, a typical Flemish floriculture crop with high added value, C. malpighianus causes severe bud malformation. To date, no information about the biology and control of C. malpighianus has been published in either scientific or specialized literature.

Research approach
We first gather knowledge about the mites' life cycle, population dynamic, intra-plant distribution and the migration in the field. The life cycle, the migration and the population dynamics is studied in the laboratory and under field conditions. We use different monitoring techniques to make these observations. The eriophyid mites are extracted from the plant material using a specialized isolation technique. The measurements are then evaluated qualitatively and quantitatively using dissection- and light microscopy.

Relevance/Valorisation
Based on the data obtained, we describe the phenology of C. malpighianus. This description may lead to a control programme that fits into the existing warning system for pests and diseases in nursery stock (PCS) and the European directive concerning IPM 2014. The knowledge and experience gained in this study can also be used in other phenological mite studies. For example, several gall and rust mites are now causing problems in agriculture and horticulture.
