Abstract
Cassida rubiginosa Muller (Coleoptera: Chrysomelidae) is a polyphagous pest and is commonly distributed across the world. This species is regarded as natural enemy of weeds by many researchers, while it is also pest of some cultivated plants. In this study, the biological parameters of C. rubiginosa fed on S. marianum and O. boissieri (Asteraceae) were investigated.Average periods of egg and 5 larval stages, pre-pupa, pupa and total development of C. rubiginosa fed on S. marianum and O. boissieri were 6.67, 7.71; 2.04, 2.19; 2.05, 2.45; 2.01, 2.74; 2.58, 3.26; 4.41, 4.88; 1.63, 2.12; 5.64, 5.35 and 26.99, 30.35 days, respectively. There were significant differences between all biological stages, except pupa stage between S. marianum and C. scolymus. Biological parameters were calculated as Intrinsic rate of increase: 0.018, 0.017; Net reproductive rate: 214.16, 357.71 and Mean generation time: 297.41, 337.19 for the populations which used S. marianum and O. boissieri as the host, respectively.
