Temperature-Dependent Biology and Population Performances of the Coffee Berry Borer (Ferrari) (Coleoptera: Curculionidae: Scolytinae) on Artificial Diet.

At different observation intervals of 1, 5, and 10 days during a trial period of 30 days, the mortality rates of were 100, 95, and 55%, and the fecundity rates were 0.55, 8.45, and 19.35 eggs/female, respectively. At temperatures of 18, 21, 24, and 27 °C, the development time of the immature stage of was significantly shortened with increasing temperature. Furthermore, the lower developmental threshold () and thermal summation () of the immature stage were 8.91 °C and 485.44 degree-days, respectively. The greatest longevity of female and male adults reached 115.77 and 26.50 days, respectively, at 18 °C. The highest fecundity was 29.00 eggs/female at 24 °C. The population parameters of were analyzed on the basis of the age-stage, two-sex life table theory. According to the data, the parameters were significantly affected by temperature. The highest net reproductive rate () was 13.32 eggs/individual at 24 °C. The highest intrinsic rate of increase () and finite rate of increase () were calculated as 0.0401 and 1.0409 day, respectively, at a temperature of 27 °C. The shortest mean generation time () was 51.34 days at 27 °C. Overall, we provide a discussion on comprehensive biological information regarding , thus providing basic knowledge for further research on this pest.
