Abstract: 

Pistachio (Pistacia vera L.) is one of the most important horticultural crops in Iran. The pistachio fruit hull borer moth, Arimania komaroffi Ragonot (Lepidoptera: Pyralidae) has been emerged as a major pest of pistachio in Iran. The purpose of this research was the study of reproduction and population growth parameters of this pest on three common pistachio cultivars with the highest acreage includes Ohadi, Kaleghochi and Ahmadaghaii. Experiments were conducted under laboratory conditions, at temperature 27.5±1oC, 65±5% RH, and 16: 8 L: D photoperiod. The results showed that the highest rate of developmental time was 50.37 day on Ahmadaghaii cultivar. The gross fecundity rates on Ohadi, Kaleghochi and Ahmadaghaii cultivars were calculated as 50.65, 44.99 and 27.14 eggs per female, respectively. The net fertility rate was significantly differed between Ohadi and Ahmadaghaii cultivars. The lowest mean daily number of eggs per female was observed on Ahmadaghaii cultivar that was significantly differed with its value on Ohadi cultivar. Intrinsic rates of increase (rm), intrinsic rates of birth (b) and finite rates of increase (l) of this pest were the lowest on Ahmadaghaii cultivar and the values of these parameters were significantly different with Ohadi cultivar. Moreover, the highest mean generation time (T) was observed on Ahmadaghaii cultivar. As a result, Ahmadaghaii was the less suitable host and had most negative impact on life-history statistics of A. komaroffi in compare with the other two tested cultivars.
