Biology and ecology of Syagrus calcaratus (F.), a cotton pest in Burkina Faso (Coleoptera, Chrysomelidae). Since 1991, Syagrus calcaratus (F.) causes heavy damages to the cotton crop in Burkina Faso. In 1994, we have studied the biology of this pest in the field and during insectarium rearing. S. calcaratus has a single annual generation, from July to October. Quiescent adults bridge the dry season, hidden in the soil in shaded areas. From the beginning of the rains, adults start feeding on non destroyed cotton plants of the last year or on other wild or cultivated malvaceous host-plants. Cotton fields are invaded from July. Larval life lasts about two months. First damages on roots start in July and continue until September.Depuis 1991, Sy...
