The Asian ladybug is a formidable predator. If it has the advantage of feeding on aphids, it also feeds on the eggs and larvae of our European ladybugs. “It destroys biodiversity. It is replacing the species from us“, stated François Verheggen.
This specimen can also have consequences on certain crops, especially for the production of grapes. Indeed, the Asian ladybug loves grapes and often clings to them. “During harvest, if you are not careful, ladybugs can get carried away with the crushed grapes. Except that these ladybugs, which smell very bad, find themselves crushed in this way. We can therefore destroy the quality of a wine in this way“, he explains.
Finally, this imported species may also have impact on our homes. Thus, at the end of summer, the Asian lady beetle usually seeks to enter buildings to overwinter in groups of several hundred to several thousand individuals. They then clump together on the ceiling, in the corners of the walls, on the curtains, etc. Local ladybugs do not have this behavior.
