Pea Weevil

Pea weevil (Bruchus pisorum) is a major pest of field peas. It is now established in all major field pea growing areas of south eastern Australia. Infested seed reduces the weight and quality of the grain and may cause rejection by millers and exporters. Importantly, control can only be achieved by preventing egg laying.

Infestation begins in the paddock when beetles lay eggs on the developing pea pods during or immediately after flowering. It is only when the next generation of beetles emerge from the harvested seed that the damage is seen. The problem of control of pea weevil must be tackled in the paddock. It is quite a different problem to that caused by other storage pests.
