Abstract
The sugar beet moth, Scrobipalpa ocellatella (Boyd) (Lepidoptera: Gelechiidae) is one of the most serious threats to sugar beet cultivation worldwide causing economically significant yield loss. The life table parameters of S. ocellatella were determined on eight sugar beet cultivars (Dorothea, Ekbatan, Merak, Palma, Rozier, SBSI 007, Sharif and Shokoofa) under laboratory conditions at 25±1oC, 60±5% RH and 16:8 h (L:D) photoperiod. The longest (15.29 days) and shortest (7.61 days) female longevity was recorded on Shokoofa, and Merak cultivars, respectively. At the same time, Shokoofa and Merak cultivars had the highest and lowest total fecundity (85.26 eggs/female) and (32.39 eggs/female), respectively. The net reproductive rate (R0) varied from 9.31 eggs/individual to 39.44 eggs/individual on eight sugar beet cultivars; the lowest value was on Merak and the highest value was on Shokoofa. The highest intrinsic rate of increase (r) (0.102 d-1) and finite rate of increase (λ) (1.107 d-1) were on the Shokoofa cultivar. The results showed that all life table parameters of S. ocellatella were significantly different on the sugar beet cultivars tested. According to the conducted laboratory experiments, Merak was the most resistant cultivar to S. ocellatella compared with the other cultivars tested.

Abstract
The goal of this paper is investigating the relationship between unemployment rate and government size in Iran. For that, we have used some VAR models, which include the following variables: government size which is measured by total government outlays as a percentage of GDP, unemployment rate, real GDP growth rate, inflation rate, and minimum wage. The results reveal that a large government sector would raise unemployment, and an increase in GDP growth rate, inflation rate and minimum wages are likely to decrease unemployment rate.

Abstract
Today, due attention of the countries, traders and policy makers to free trade zones is among the first priorities of the economic policies of the world.
Because these zones play an important role in the economic development of the world. In this paper, evaluation and prioritization of Iranian free trade zones was using the MADM method. The main goal of this research was to optimize the re-allocation of economic recourses. The results indicated that the Kish free zone is of higher priority comparing with the other free zones.
The results of this research and prioritization of free trade zones could be highly useful in increasing the F.D.I. and access to world and regional markets.
