Damage caused by black vine weevil and its larvae

The black vine weevil is one of the most important pests in gardens and roof gardens. Its larvae feed especially on the roots of plants, which can cause wilting and eventual death. The adult beetles feed primarily on the leaf edges of the affected plants, resulting in the typical and unsightly "bay feeding".

Application of nematop® weevil-stop

Simply place the trap near the infested plants. Make sure that the grooves point downwards. The nocturnal beetles hide during the day and crawl under the trap. There they come into contact with the nematode gel. The nematodes now penetrate into the beetles and fight them.

Control adult black vine weevils with nematodes.

nematop® weevil-Stop is a trap for the control of adult black vine weevils. It consists of a wooden board with grooves, in the grooves is a gel with nematodes. The beetles are nocturnal and crawl into the grooves when they are looking for a protected place for the day. During their stay, the nematodes penetrate the beetles, where they secrete a bacterium that kills the beetles. After about two weeks, the number of black vine weevils is reduced by 80-100%.

How do nematodes work?

Nematodes are about 0.5 mm long, of which there are over 20,000 different species worldwide. The species Steinernema carpocapsae specializes in controlling adult black vine weevils and is particularly effective. As soon as the beetle comes into contact with the gel, the nematodes penetrate it and secrete a bacterium with which they live in symbiosis. The bacterium kills the beetle and the nematodes multiply inside it until it is consumed. The nematodes then move on to infest the next pest. This process repeats until all black vine weevils are controlled.
