<p>Numerous species of insect pest have been found causing serious damage to citrus plants in Turkey. Chrysomphalus<br />aonidum (L.) (Diaspididae), and Coccus hesperidum L. (Coccidae) from Hemiptera among them are potential insect<br />pest, which cause huge economic losses to citrus. The current study investigated life table parameters of both pests,<br />which included net production rate (R ), intrinsic rate of increase (r ), mean generation time (T ), doubling time (T ), total 0 m 0 2<br />production rate (GRR) and finite rate of increment (&lambda;). Results showed that net production rate (R ) of both C. aonidum 0<br />and C. hesperidum were 74.001 and 185.295 female/female/offspring, respectively. The intrinsic rate of increase (r ) for m<br />the pests was calculated as 0.052 and 0.047 female/female/day, respectively. Similarly, the mean generation time (T ) 0<br />was recorded 82.030 days for C. aonidum and 110.985 days for C. hesperidum. The doubling time (T ), gross 2<br />reproduction rate (GRR), and finite rate of increase (&lambda;) were recorded 13.320 days, 142.555 eggs/female and 1.054<br />egg/female/day respectively for C. aonidum whereas, in case of C. hesperidum, the aforementioned values were<br />calculated as 14.732 days, 579.047 eggs/female and 1.048 eggs/female/day, respectively.</p>
