Abstract
Although the pea weevil, Mylabris pisorum, is one of our oldest pests and one whose control has long been considered solved, the writer is unaware of any place it is being controlled. Our present controls are based on the assumption that the weevil in the seed is the important source of infestation. The writer has planted weevil infested peas under weevil tight cages and grown them to maturity without infestation occurring, which indicates that weevil planted in seed is not the source of infestation. By over wintering weevil in protected places out of doors, he has brought as high as 87 percent of them through the winter, thus showing that it is possible for a high percentage of weevil, escaping from the peas before being stored, may over winter out of doors and therefore may be important as the source of infestation.
