Abstract
The biology of the imago of Sitona limosus Rossi in the northern part of Israel was studied. The weevils cclose in earthen cells, prepared by the larvae toward pupation, during April and May. They remain in the cells, in a preactivity diapause, during the dry summer. They emerge early in the rainy season, in November and December, ready to feed. Their hosts are bean, vetch, and pea, which at that time are in the early stages of development. Being incapable of flight, the weevils must move to a host, or starve. Oviposition starts about four days after the beginning of feeding and continues throughout the life of the female, until March and April. In the laboratory, females laid up to 4328 eggs (average 1955.2). Separation from males after fertilization did not impede oviposition.
