Acanthoscelides obtectus, the bean weevil, is a species of beetle. The species was described in 1831 by Thomas Say.
Bean weevils feed on vetches, beans and other leguminous plants. They are generally considered a pest species for this reason.
Originating in Central America they have been inadvertently spread around the world in grain shipments.
Bean weevils are small beetles, ranging in size from 2 to 5 mm.
Bean weevils develop and feed upon leguminous plants. Adult bean weevils hibernate inside the seeds or seed pods of these plants.
Adults emerge from hibernation in April to mate. Female bean weevils lay eggs onto seed pods, or into them by chewing holes, in groups of 2 to 20 eggs. A single female can lay up to 200 eggs but 40 is average fecundity.
Egg development can take 30 to 45 days before a 1st instar larvae merges. After approximately 3 days the larvae then moults and becomes a second instar larvae which then begin to consume the seed, with the larval stage lasting 3 to ​3 1⁄2 weeks in total.
The larvae then pupates inside the seed, taking 9 to 29 days. The life cycle of a single generation takes from 100 to 110 days.
The bean weevil is a significant pest in some parts of the world, especially in areas such as Australia where it is non-native.
It damages crops both in situ and when stored in warehouses, and can potentially reduce crop yields by 60% as the larvae develop at the expense of the seeds.
