Abstract:
Studies on the coriander aphid (H. coriandri) were conducted on the life table of C. zastrowi sillemi during the years 2020-21 at constant temperature of 25±1 °C. According to observations, the maximum ages of the egg, larva, pre-pupa, and pupa were 4, 13, 2, and 4 days, respectively. With a mean length of generation (Tc) of 42.68 days, the net reproductive rate (R0) of 68.05 was obtained. The population increased by 2.0784 times per week. The intrinsic rate of natural increase in numbers (rm) was 0.0989 females/female/day. The eggs, larvae, pre-pupae, pupae and adults each contributed 39.97, 47.76, 2.61, 3.84 and 5.81 percent when, it came to the stable age distribution. The life expectancy (ex) of newly deposited eggs was only 15.17 days.
