A comparative study on the intrinsic rates of increase of Cyrtobagous singularis and C. salviniae on the water weed Salvinia molesta



A comparative study on the intrinsic rates of increase of Cyrtobagous singularis and C. salviniae on the water weed Salvinia molesta



Entomologia Experimentalis et Applicata 423: 231-237



The intrinsic rates of increase (rm) of Cyrtobagous salviniae from Brazil and C. singularis from Trinidad were determined in the laboratory at 23, 27 and 31 degrees C on nitrogen-rich plants of the aquatic weed Salvinia molesta. Variation in oviposition and immature survivorship accounted for most of the differences between species in rm values (exponential growth of a stable-age population in a non-limiting environment).
