The Content Of The Article:


The Frayed Black-weevil is about ten to twelve millimeters long and black in color. The nocturnal, flightless beetle attacks, for example, rhododendrons, strawberries and many potted plants. The beetle eats bay-shaped holes in the leaves. Its yellowish-white or brown larvae live in the ground and eat the roots of the plants. They cause the greater damage because the plants can die off.


In May and June at night read the beetles from the leaves. In wilting plants examine the potting soil for larvae. Predatory nematodes can be exposed as beneficials with the irrigation water against the larvae. Vouchers for the order of the nematodes are available in the garden shop. Natural enemies of the weevil are hedgehogs and shrews; they should be promoted in the garden.
