Abstract

Crop failures are a frequent phenomenon of saskatoon berries, Amelanchier alnifolia Nutt., in Saskatchewan. The curculionid beetle Tachypterellus quadrigibbus Say is shown to have a pronounced effect on the relation and quality of fruit produced. Its feeding and reproductive habits on the berries are proposed as a major cause of crop failures.
