The biting midges (Ceratopogonidae) are relatively well studied dipteran family that includes over 6000 extant species in 110 genera. They are known as vectors of several arboviruses of veterinary importance including bluetongue, bovine ephemeral fever, African horse sickness and Akabane virus, as well as the medically important Oropouche virus. A key For Ceratopogonidae of Markazi province is presented. Four genera, 8 subgenera and 9 species were found. 5 species which marked with an asterisk (*), are new records for Iran.

During 2011 and 2012, field studies were conducted in different parts of the South of khorasan, where contaminated to Russian knapweed to find its natural enemies. Three insect species Urophora xanthippe (Dip.: Tephritidae) and Metzneria paucipunctella Zeller (Lep.: Gelechiidae) and Acanthiophilus helianthi Rossi, 1794 (Dip.: Tephritidae( were identified. M. paucipunctella (Zeller, 1839) (Lep. Gelechiidae) is introduced for the first time for Iran and U. xanthippe (Munro, 1934) for the first time for fauna of Khorasan. Results showed that overwintering larvae of U. xanthippe become pupae in early May and converted to adult after 7/13 (d). Adults emerge from pupae and mate after 3 (h) with no feeding. Due to the high potential of head flies in reducing the number of seeds and also due to the limited host range of the knapweed, the insect can be used in biological control of knapweed.

The Sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), is one of the most important pest of wheat in Iran and some neighboring countries. The nymphs and adults cause sever quantitative and qualitative damage by feeding on leaves, stems and grains. Unfortunately, pesticide application is the main method of the sunn pest control, so finding the alternative methods are important. Precocene which is a juvenile hormone inhibitor, exerts cytotoxic effects on corpora allata of insects species, resulting necrosis of parenchymal cells, the source of juvenile hormone. At laboratory studies, precocene I and precocene II with different concentrations (0, 20, 25, 32, 40 and 50 μg) were applied topically to the thoracic surface of the fifth instar nymphs. The results showed that percent mortality increased with increasing concentrations of the hormones. The highest mortality (50%) was observed in concentration of 50 μg precocene II. Treated nymphs with precocene I and II led to appearing of deformed insects in fifth instar and adults. Also, the morphological abnormalities such as strong deformation of wings and hemelytron and persistence of old cuticles were observed.  Increasing nymphal period was also resulted using precocenes   Manuscript profile

Habrobracon hebetor is one of the most important parasitoid of some agricultural pests such as cotton bollworm and corn stem borers and etc. This natural enemy is mass reared and released in many regions of Iran. Biological parameters of H. hebetor such as percent parasitism, reproduction, male percentage and adult's longevity were investigated in the third, fourth and fifth instar larvae of flour moth, Ephestia kuehniella Zeller. The experiments were conducted at 26°C, 60±5% humidity and 16:8 light/dark ratio. Also percent parasitism, reproduction and The sex ratio of eight consecutive generations of H. hebetor were evaluated on fifth larval stage of E. kuehniella.The obtained results showed that the highest percentage of parasitism (99.3%), reproduction (63.80 wasps) and adult's longevity (19.40 days) were observed on fifth instar larvae of the flour moth. significant difference was obserred between male percentage of H. hebetor on the third, fourth and fifth instar larvae of flour moth. Also the results showed no significant difference between percentages of parasitism of H. hebetor in eight consecutive generations. The highest (63.95%) and lowest (28.60%) male percentage were observed in first and eighth generation of the parasitoid, respectively. The highest parasitism was observed in the first generation of H. hebetor. Manuscript profile

The cotton shedder bug, Creontiades pallidus Ramber (Hemi.: Miridae) is one of the most important pests of cotton in Khorasan Razavi province, Iran. In recent years this insect had always been a main pest for cotton in east of Iran especially in Sabzevar region. To evaluate the damage caused by pest on different cultivars (Bakhtegan, Khordad, Sahel, Sepeed, Mehr and Varamin), an experiment was carried out at the Agricultural Research Station of Sabzevar during 2013-2014. Experiment was designed as randomized complete blocks with six treatments and four replications. In this study, ten constant plants in each plot were selected randomly and marked for sampling until the end of the project. On each count, the number of black spots due to feeding of C. pallidus on all bolls of each plant was counted and finally, the mean number of black spots on 10 plants were calculated. Samples were taken on 14 occasions from 14th July to 14th October 2013. Analysis variance showed a significant difference among the cultivars at the level of 1%. The mean comparison of cultivars treatments showed that the highest and lowest damage by C. pallidus were observed on the Varamin, Bakhtegan and Mehr cultivars, respectively. Manuscript profile

The Cold plasma as a new, eco-friendly and economic technique has obtained important achievements in various spheres and can be considered in the field of pest control.The aim of this study was to examine the insecticidal effect of The cold plasma on stored product pests, Ephestia kuehniella (Lepidoptera.,Pyralidae) and Tribolium confusum (Coleoptera, Tenebrionidae). Pathogenic stages of the pests were exposed to cold plasma in two conditions, without product and with 10 g of wheat, for different exposure times in various voltages of 5, 7and 10 KV. Each test was done on 20 insects in 4 replicates with control. Obtained results confirmed The insecticidal effect of The cold plasma on the pests. Larval stage was more sensitive than the adult and higher percentage of mortality was observed in larvae of T. confusum compared to E. kuehniella. Changes in physical parameters of cold plasma such as increasing the voltage and exposure time of treatment caused more mortality.LT50 values at maximum voltage were 7.60, 11.94 and 9.57 s for larvae and adults of T. confusum and larvae of E. kuehniella respectively. It is hoped that by optimizing the equipment for commercialproduction of cold plasma we use it for controlling the stored product pests. Manuscript profile

Searching for less hazardous compounds for human and invironment the fumigative toxicity of five terpenoid compounds including carvacrol, myrtol, menthol, camphen and a-pinene were investigated on Callosobruchus maculatus (F.) as one of the most important stored product pests. Experiment was carried out at 30 ± 2 ˚C and 60 ± 5% relative humidity (R.H.) under dark condition. Each compound were tested with six concentrations and four replications including control. According to the trial experiments the fumigant toxicity of the studied essential oils differed significantly , distinct concentrations of each compound used.  The results showed that all compounds studied had significant  mortality on the pest. Among  them, Myrtol showed the highest fumigative toxicity on C. maculatus. The value of LC50 of Myrtol was 47.05µl/lair while LC50 of Carvacrol, Menthol, Camphen and α-pinene were respectively  51.53, 107.39, 61.35 and 57.41 µl/lair. It is concluded that the terpenoid compounds may be used in the pests of post-harvested products in stores. Manuscript profile
