Hey guys!

I was asked to find information about Bradybatus creutzeri Grem. (Maple weevil-seed eater), biology, control measures, etc., and I don't have much information at hand, especially in Russian. Can anyone tell you what books you can look at? There was this species in the Fauna of the USSR/Russia?

Thanks!

It exists not only in the Crimea, but now also in our North-West, and has been known since the 1980s from the work of Bulygin and Firsov. Damages the winglets of silver maple Acer saccharinum L. as this species bears fruit in summer early in June. I think you should try to catch it during the summer. I'll have to have a consultation at the department.

Young beetles come out from the end of July to September, gnawing round holes in the fruit shell. additionally, they feed on maple pedicels, causing the flowers to wither. They overwinter in the forest floor. Damages preim maples. in forest-steppe and steppe zones, often destroying up to 50% of the seed crop. Control measures are not developed, possibly spraying. systemic insecticides, collecting and destroying infected fruits before the beetles come out of them.
