Studies on the Fecundity and Longevity of Cyrtobagous salviniae (Coleoptera:Curculionidae), an Effective Biocontrol Agent of Salvinia molesta in India
Cyrtobagous salviniae Calder and Sands (Coleoptera: Curculionidae), of Brazilian origin, is an effective biocontrol agent of the floating aquatic weed Salvinia molesta D.S. Mitchell in India. Laboratory studies on the fecundity and longevity of the weevils showed that the females lived for 231 days (average) and laid 290 eggs (average). Thc mean daily egg production per female was 1.08.
