Abstract

The cabbage aphid, Brevicoryne brassica L. (Hem., Aphididae) is one of the most important pests of rape seed and most other crucifera in many parts of the world. In this study, demographic parameters including LIFE TABLE, REPRODUCTION and POPULATION GROWTH parameters of two populations of B. brassicae, collected from Shiraz and Gorgan, were studied. Experiments were conducted in laboratory conditions at 25±1oC, 60±5% relative humidity and a photoperiod of 16:8 hours (L:D). Data were analyzed according to Jackknife method using SAS and MINITAB statistical softwares. The results indicated that, there was significant difference between mean preimaginal developmental time of aphid in two population of Shiraz and Gorgan (P<0.05). There was a significant difference between mean lifespan of aphid in two population of Shiraz and Gorgan. The life expectancy of newly emerged adults was 7.92 and 9.46 days in two populations of Shiraz and Gorgan, respectively. The gross fecundity rate in Shiraz population was higher than Gorgan population. There was a significant difference between gross fecundity rate in two population of Shiraz and Gorgan (P<0.01). The net REPRODUCTION rate was 9.22 and 7.54 females per female per generation in Shiraz and Gorgan population, respectively. The intrinsic rate of increase in two populations of Shiraz and Gorgan were 0.21 and 0.19 females/female/day, respectively. The finite rates of increase were obtained 1.23 and 1.21 days in Shiraz and Gorgan populations, respectively. The mean generation time of aphid was 10.58 and 10.48 days in two populations of Shiraz and Gorgan, respectively. The doubling time of aphid was 3.30 and 3.59 days in Shiraz and Gorgan populations, respectively.
