During 2008-2009, in a faunal study of Miridae family in the agricultural farmlands and gardens of Arak and the suburbs, 25 species belonging to 17 genera of 5 subfamilies were identified; A  species marked with asterisk, is newly recorded from Iran. Most of collected species, are                  phytophagous, where, some of them have been already introduced as agricultural pests. For                example Lygus rugulipennis Poppius 1911, as an important agricultural pest in Arak, the most abundant species among the harmful collected species (35/09%), but few studies have been                conducted regarding its economic importance. The rest of the species (6 species) are predator  which among them Deraeocoris punctulatus (Fallen, 1807) was determined as the dominant               predator.

In this study the parasitoids occurring on pupa of (GBM) Lobesia botrana (Denis & Schiffermüller) which is the most serious pest of grape in Orumieh vineyards, was collected and identified during 2004-2006 and their potential in natural biologic control was assessed in 2005 and 2006 years. Pupae of grape berry moth were collected from under loosen barks of insecticide-free vineyards of Kahriz horticulture station from early October until mid April (emergence of GBM adults in nature) and reared in containers at 25±2°C 50% relative humidity in laboratory. Emerged adult parasitoid were identified and their relative abundance was determined. Rate (%) of parasitism for L. botrana pupa was calculated as the number of parasitoids over the total amou of emerged parasitoids and moths, and their emergence trend was discussed according to 2005 and 2006 years data. Six parasitoid species including: Itoplectis tunetana (Schmiedeknecht), Pimpla arcadica Kasparian, Pimpla sp.nr confinis Kasparyan and Dicaelotus inflexus Thomson belonging to Ichneumonidae and Pteromalus puparum(L.) and Homoporus sp. belonging to Pteromalidae were reared from grape berry moth pupae. The species P. arcadica, P. confinis and D. inflexus are new for insect fauna of Iran and the occurrence of all parasitoids on GBM pupa are reported for the first time. Pupal parasitism ranged from 13 to 42 percent in various sampling occasions with an average of 20.6 ± 2.80 percent for two years. Manuscript profile

The cabbage aphid, Brevicoryne brassicae L.(Hem., Aphididae), is an important pest of canola in Iran and causing serious direct and indirect damage to canola fields. In this research, effect of some IGRs such as: Pyriproxyfen, Hexaflumuron, flufenoxuron (at 500, 750,1000 ppm concentration) and imidacloprid (1000 ppm concentration) on cabbage aphid was evaluated in growing season of 2008-2009 in Pasargard region of Fars province. Samplings were conducted before spraying and three times after the spray at 3, 7 and 14 days interval. Statistical analysis of results including aphid mortalities as well as yield assessment showed that treatment of imidacloprid, inducing 87% mortality along with 1990 kg/ha yield, differed from the others, significantly. Among the insect growth regulators, hexaflumuron with 85% mortality, was the most percent of mortality and increased yield of crop. Based on overall results, hexaflumuron insecticide at 1000 ppm concentration could be one of the recommended pesticide for controlling cabbage aphid. Manuscript profile

The Indian meal moth, Plodia interpunctella Hubner (Lep., Pyralidae) is one of the serious pests of stored date in Iran and many parts of the world. In this research life table and reproduction parameters of P. interpunctella on three cultivars of date were studied. The experiments were conducted in laboratory conditions at temperature of 27±2 ºC, 45±5% relative humidity and a photoperiod of 16L:8D hours. The results indicated that, the life expectancy in egg period were 44/45, 52/29 and 47/89 days on Zahedi, Shahabi and Kabkab cultivars, respectively. The gross fecundity rate on Zahedi, Shahabi and Kabkab cultivars were estimated 172.1±17.5, 160.2±15.2 and 121.0±18.3 egg per female, respectively. There was no significant difference among gross fecundity rate on different cultivars of date. The net fertility rate on Zahedi cultivar with 96/8±10/4 was more than the other cultivars. The lowest value of this parameter on  Kabkab cultivar 43/84±7/26 was estimated that there was significant difference with Zahedi and Shahabi cultivars, but no significant difference was observed between Zahedi and Shahabi cultivars. The mean egg per day and mean fertile eggs per day of moths developed on Zahedi cultivar were estimated 25/09±2/61 and 22/38±2/30, respectively that was shown the maximum value among examined cultivers.

This research was carried out in order to understand the pollination efficiency of pollinators in fruit set percentage, and distinguish cross pollination status in Golab apple cultivar, in two orchards located in Shiraz, Iran during mid February to end of September, 2009. In orchard 1 with no honey bee hive, 24 flowering branches containing similar inflorescences were covered with cylinder cages made from fabric net. In blossom stage 3 females of honey bees were released into the cages for pollinating as treatment a. In second treatment (treatment b), to preventcross pollination, flowers were covered with special cage. In control treatment, flowers exposed for natural pollination. In second orchard which had two honey bee hives, 24 flowering branches were covered by special cage to prevent from cross pollination and in check treatment flowers exposed to open pollination. Analysis of variance in fruit setting in the first orchard showed a significant difference setting. The means of fruit set in treatment a (flowers covered with net cages), treatment b (flowers covered with special cage) and control (open pollination) were 54%, 7.2 % and 20.4% respectively. The means of fruit set in the orchard 2 for control and other treatment were 51% and 1.6%, respectively. It is concluded it is recommend to use honey bee to increase Golab apple production.   Manuscript profile

Pomegranate fruit moth (PFM), Ectomyelois ceratoniae (Lep., Pyralidae), is the most important pest of pomegranate in Iran. Application of the kaolin particle film (Sepidan® WP) might be an alternative for control of the pomegranate fruit moth and reduction of pomegranate sunburn. To assess the impact of kaolin on damage of pomegranate fruit moth, preliminary trials were conducted in the fields during spring to summer 2009 in Garmsar region of Iran. The different concentrations of kaolin (2.5, 5, 10 and 15%) were sprayed over the whole canopy and fruits four times at 4–5-week intervals from early May to early September. Based on the field studies, the infection rates of PFM were 9.3 and 2.4% for control and kaolin treatment (at 15% concentration), respectively. Sunburn damage of fruits was reduced in the kaolin WP-treated fruits. Also the result showed that, the flower & fruit drop, fruit cracking, aphids damage was reduced in kaolin treatments. Therefore, kaolin could be used successfully to reduce biotic and abiotic harmful agents on pomegranate. Manuscript profile
