        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

        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 More
        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

        5 - Ovicidal effect of three plant essential oils on Callosobruchus maculatus F. (Col., Bruchidae)
        J. Shakarami L. Pourhosseini R. Vafaei-Shoushtari Sh. Goldasteh
        In order to find recyclable, environment friendly and easy accessible insecticides, the essential oils of three plant species including Mentha aquatica L., M. piperita L. and Anethum graveolens L. were used against the eggs of Callosobruchus maculatus. The experiment wa More
        In order to find recyclable, environment friendly and easy accessible insecticides, the essential oils of three plant species including Mentha aquatica L., M. piperita L. and Anethum graveolens L. were used against the eggs of Callosobruchus maculatus. The experiment was conducted in 6 replications using a completely randomized design of factorial experiment. The essential oils were prepared by water distillation method. Experiment was carried out at 30±2 ˚C and 60±5% R. H. under dark condition. Results show that all three plant essential oils reduced percentage of egg hatching significantly. At the concentration of 37.03 µl/lessential oils of M. aquatica, M. piperita and A. graveolens caused 100, 100 and 92.73% mortalities of eggs, respectively.Values of 50% lethal concentrationon eggs were 2.628, 3.806 and 4.468 µl/l for M. aquatica, M. piperita and        A. graveolens, respectively.

        Carmine spider mite, Tetranychus cinnabarinus Boisduval, is an important pest of ornamental plants such as roses in the world. In this research, population changes and the growth parameters of T. cinnabarinus reared on three rose cultivars (Magic Red, Polar Star, Dolce vita) at different amount of nitrogen fertilization (0, 50 and 100 Kg ha-1) were evaluated at 27±2°C, 70±5% RH and 16: 8 h (L: D) photoperiod. The highest and lowest abundance of mites were observed at levels of 100 and 0 (control) Kg ha-1 nitrogen. In all levels of nitrogen, the density of pest were the highest (79.25) on the Magic Red and lowest on the Dolce Vita variety. Also results showed that on all varieties, the 100 Kg ha-1 nitrogen provided the highest intrinsic rate of increase (rm), finite rate of increase (λ) and net reproductive rate of (R0). By increasing the rate of fertilizer, the doubling time of population (DT) decreased and the mite completed its generation in the shortest time (T). This study revealed that the use of high levels of nitrogen can considerably increase population and reproductive rate of carmine spider mite in rose greenhouse. Manuscript profile

        S. Mahmoodvand J. Shakarami R. Vafaei-Shoushtari
        The effects of four plant essential oils of Mentha longifolia, Thymus deanensis, Achillea wilhelmsii and Artemisia hausskenechtii were investigated on adult stage of Tribolium castaneum and T. confusum. The essential oils were prepared using water distillation method. E More
        The effects of four plant essential oils of Mentha longifolia, Thymus deanensis, Achillea wilhelmsii and Artemisia hausskenechtii were investigated on adult stage of Tribolium castaneum and T. confusum. The essential oils were prepared using water distillation method. Essential oils were used in five concentrations and five replications. The concentration selected based on primary experiment for each essential oil. Mortality rate of insects were recorded after 3, 6, 24, 48 and 72 hours. Results showed that the longer exposure of insect to essential oil and the higher concentration of essential oil, increased  mortality of the two beetle species in all treatments. There was significant difference among mortality effect of the essential oils. The LC50 value of M.longifolia after 24 hours for T. castaneum and T. confosum were 11.59 and 10.67 µl/lair respectively, while the values of LC50were 89.21 and 99.79 for T. daenensis, 55.40 and 98.71 for A. wilhelmsii and 60.64 and 62.25 µl/lair for A. hausskenechtii, respectively. The least LT50 recorded was in A. hausskenechtii essential oil with 23.10 and 21.10 hours against T. castaneum and T. confusun, respectively. Results showed that these essential oils can be as safe botanical pesticides for control of storage pests. Manuscript profile
