Combating vine weevil successfully

The black vine weevil, Otiorhynchus sulcatus, is a pest in many ornamental crops (e.g. rhododendron, cyclamen and azalea), as well as in strawberries and other fruit crops in both temperate and sub-tropical regions.

Biological solutions
The larvae and pupae of the black vine weevil (Otiorhynchus sulcatus) can be controlled with beneficial nematodes. Depending on the soil temperature, Larvanem (Heterorhabiditis bacteriophora) or Entonem (Steinernema feltiae) can be used in tree nursery crops (yew, thuja, rhododendron), berry cultivation, strawberries, ornamental crops and various pot plants, etc.

After application, the parasitic nematodes actively hunt for the larvae and penetrate them. The nematodes then feed on the contents of the larvae, releasing certain bacteria from their intestinal tract. These bacteria convert tissue from the host into substances that are easy for the nematodes to absorb. The larvae die within a few days. The population development of the nematodes within the host population is dependent on the number (dosage) applied and the size of the host population. In this regard, it is important that Larvanem and Entonem be applied on uncovered, moist soil.
