Abstract

Pistachios are one of the most important garden products of the country. The pistachio green stink-bug, Acrosternum millieri Mulsant & Rey (Hemiptera: Pentatomidae) is one of the important and key pests of pistachio in Iran. The adults of the pest collected from the pistachio orchards of Rafsanjan in 2017 and reared on fresh kernels of pistachio head ram species in the growth chamber at 27 ± 1 ˚C, 65 ± 5% RH and a photoperiod 16: 8 h (L: D) and the parameters of age-stage, two sex life table of the insect were determined. The net reproduction rate (R0) was equal to 26.29±4.11 (offspring/individual), the gross reproduction rate (GRR) was equal to 54.28±5.91 (offspring/individual), intrinsic rate of natural increase of population (rm) was equal to 0.061±0.0031 (female/female/day), the mean generation time (T) and the finite rate of population increase (λ) were 53.44±0.50 (days) and 1.063±0.0033 (subject/substance/day), respectively. The obtained results have been discussed in terms of developing appropriate integrated pest management (IPM) programs against the pest by forecasting population growth rate.
