摘要

Anthonomus rubi is one of the key pests in organic strawberry production. The adult female is able to reduce the yield of strawberries up to 60% by cutting of the flower stalks after laying the eggs in the unopened flower buds. These damaged buds ceased to develop and either fall to the ground or remain dangling from the partially severed stalk. While strawberry cultivars with a higher number of flower buds tend to compensate these losses, cultivars with a smaller number of flower buds, like Malwina,don’t. So that the strawberry blossom weevil can cause severe yield losses and an economical disaster for the grower. One control possibility in the first year to reduce the amount of damaged flower buds is covering the plants with fleece or net. But as several one year field trials in 2010 and 2011 showed, a careful control management is necessary to reduce the damages and increase the yield amount of first class fruits significantly at the same time. Therefore one important key is the timing of covering the plants before the weevil enters the field. The other key is to provide a less stressful climate for the strawberry plants and developing fruits under covering conditions. Otherwise the yield of the first class fruits could be significantly negatively affected. Additionally the amount of the second class fruits could significantly increase as also the amount of the decomposed fruits.
