The black vine weevil, Otiorhynchus sulcatus F. has been a pest of nursery and small fruit crops in Europe and in the Pacific Northwest and the Atlantic Northeast areas of North America for more than 100 years. The larval stages of these pests cause plants to die or reduce growth by eating the roots of these plants. This pest, alone, has been estimated to cost nursery and small fruit growers in the state of Oregon more than $3 million/year. For more than 100 years pest control researchers have been unable to provide workable solutions for control of this pest. This has been because it has been difficult if not nearly impossible for these researchers to have enough eggs, larvae or adult weevils to conduct proper tests with chemical, biological or chemical controls. This presentation describes a technique that produces over 2500 black vine weevil larvae, 500010,000 eggs and 300500 adult weevils for use in experiments on a weekly basis. This is the first continuous mass rearing method described for this pest.
