| Abstract: | The prey consumption and preying ability ofCybocephalus micans Reittei,C. nigriceps nigriceps (J. Sahlberg), andC. binotatus Grouvelle, while fed on several armoured scales, were studied. Larvae and adults ofC. micans andC. n. nigriceps required small amounts of prey (developmental stages ofAonidiella aurantii Maskell]) in order to complete their development, survive and reproduce. Adults were almost incapable of feeding on female diaspidid scales, and when supplied with females only, their survival was low and reproduction stopped. Adults of the imported speciesC. binotatus were able to feed and survive on females ofA. aurantii much better than was the local species. Under the same conditions of temperature and relative humidity, adult survival ofC. n. nigriceps under starvation was always longer than that ofC. micans |
