After that, the pupal lasts about 6 days. The weevil is not a strong flyer, less so than Sitophilus zeamais, and spread to new locations is by adults and larvae on and inside consignments of grain.

The weevil is considered a very destructive pest of stored grain, rice, maize, barley and wheat. In larger parties, fumigation with phosphoresced hydrogen is the solution. Most of the bugs and larvae flowed off into the sink. Two larvae can develop in one wheat kernel, but only one larva of the granary weevil … The rice weevil cannot survive the winter in warehouses with temperatures below 10 ° C. 3 weeks at 0 ° C kill eggs, larvae and adult beetles.
