Abstract

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