  In order to find a suitable alternative to conventional pesticides, fumigant toxicity of essential oils from Mentha longifolia, Tagetes minuta and Salvia macrosiphon were tested against adult of Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidae) on laboratory condition. The experiment was conducted using a completely randomized design of factorial experiment with five concentrations and three replications at 25±10C, 60±5% R.H in darkness. The results showed that the percentage of mortality was increased with increase in concentration and exposure of time. The results also showed the effect of fumigant toxicity of Mentha longifolia was weaker than Salvia macrosiphon on the studied insects. The LC50 values were evaluated by M. longifoli, T. minuta and S. macrosiphon were 9.595, 12.434 and16.649 μl/l after 12h as well as 7.422, 9.128 and 13.071 μl/l after 24h for T. castaneum, respectively. Mean adult mortalities of Tribolium castaneum, at the highest concentration of essential oils (25μl/l), by M. longifolia, T. minuta and S. macrosiphon as 76.6%, 73.3% and 63.3% after 12h as well as 90%, 76.6%, and 70% after 24h, were recorded, respectively. It was found that plant essential oils could be used as a safe pesticide or model for new synthetic pesticides to control of insect pests Manuscript profile

  The Jasmine moth Palpita unionalis Hubner (Lep., Pyralidae) is one of the most important pests of plants from Oleaceae, such as privet (Ligustrum ovalifoliumHassk) and olive (Olea europea L.). This insect has been introduced to Iran in recent years. Therefore, it needs More

  The Jasmine moth Palpita unionalis Hubner (Lep., Pyralidae) is one of the most important pests of plants from Oleaceae, such as privet (Ligustrum ovalifoliumHassk) and olive (Olea europea L.). This insect has been introduced to Iran in recent years. Therefore, it needs extensive      researches according to its new ecological conditions. In this regard, the plant host preference of the pest was studied to find an alternative plant host for rearing the jasmine moth. The biological parameters of this moth compared when reared on the two plant hosts (north of Iran). Pupae of the pest were collected from the trees and nurseries of olive at Tarom region. Adults emerged were transferred to growth chamber for rearing at the conditions of 25±0.5 ˚C, RH %65±5 and 12L: 12D. Biological parameters such as number and period of generation, larval feeding rate, larval           development time and mortality, sex ratio and adults longevity were compared on olive and privet. The pest has five instars on two hosts but larval duration is shorter on privet. Also it feeds much more quantity of leaves of privet. The rate of mortalities were not different significantly. This     insect produced 8 and 10 complete generations on olive and privet, respectively. According to the accomplished studies, host suitability was similar, but the privet is more available and inexpensive than olive for laboratory rearing of jasmine moth. Manuscript profile

  The study were done during 2010-2011 to investigate the integrated effects of different doses of gamma radiation and diatomaceous earth (INSECTO®) on Red Flour Beetle Tribolium castaneum (Herbst) in laboratory conditions (27±1°C, 60±5% humidity, da More

  The study were done during 2010-2011 to investigate the integrated effects of different doses of gamma radiation and diatomaceous earth (INSECTO®) on Red Flour Beetle Tribolium castaneum (Herbst) in laboratory conditions (27±1°C, 60±5% humidity, dark room). In this study, adults of red flour beetle were grown on mashed corn (50 gram) and then treated with different doses of Gamma ray (100, 500 and 1000 Gray) and three doses of diatomaceous earth (0.5, 1 and 1.5 g kg-1). Percentage of mortality were recorded after 1, 2, 7, 14, 21, 28, 35 and 42 days and compared with control. Results showed significant differences among various doses of diatomaceous earth (DE) and Gamma ray and their interactions in most days after treatment. In comparing the means mortality in different doses of diatomaceous earth (DE) and various doses of Gamma ray, most mortality were recorded after 35 days in 1.5 gr/kg diatomaceous earth and 1000 Gray Gamma ray separately. In combination of Gamma ray and diatomaceous earth, most mortalities were recorded after 35 days for 1 and 1.5 g kg-1 (DE) combined with 500 and 1000 gray Gamma ray. It is concluded that 1 gkg-1 (DE) combined with 500 gray gamma ray is the best combination of the lreatmants. Manuscript profile

  هدف اول این مطالعه ارائه یک مدل قوی جایگزین به منظور توصیف کینیتیک تجزیه شکمبه‌ای علوفه و همچنین حداقل نمودن مشکلات برازش بود. برای این منظور مدل (KU) Korkmaz-Uckardes که یک ساختار لگاریتمی دارد توسعه داده شد. هدف دوم این مطالعه تخمین پارامترهای tp (زمان برای تولید p درصد از ناپدید شدن جزئی ماده خشک در شکمبه) و Rtp(نرخ ناپدید شدن جزئی ماده خشک در زمان t) با استفاده از مدل KU بود. این فراسنجه‌ها داده‌های مفیدتری را برای مقایسه خوراک‌ها در مطالعات تجزیه‌ای در شرایط آزمایشگاهی فراهم خواهند نمود. هدف سوم، ارزیابی عملکرد مدل بود. معیارهای آماری استفاده شده برای ارزیابی عملکرد مدل عبارت از آنالیز باقیمانده‌ها (تعداد اجرا و آزمون دوربین-واتسون) و آزمون شایستگی برازش‌ها (مربعات میانگین باقیمانده‌ها، ضریب تعیین و فاکتور صحت) بودند. آنالیز باقیمانده‌های مدل KU معنی‌دار نبود (05/0P<) باقیمانده‌ها نرمال توزیع داشتند. مطابق با شایستگی برازش‌ها، مدل KU برای تمامی داده‌ها برازش خیلی خوب نشان داد. مطابق با آنالیز همبستگی پیرسون یک همبستگی معنی‌دار (989/0r2=) بین مقادیر مشاهده شده و پیش‌بینی شده بود (01/0P<). نتایج مشخص نمود که مدل KU می‌تواند به عنوان یک مدل جایگزین برای توصیف و تفسیر تجزیه ماده خشک در شرایط آزمایشگاهی برای خوراک‌های طبیعی استفاده شود.

  Giardiasis is an intestinal infection caused by the flagellate protozoan Giardia lamblia (synonyms: Giardia intestinalis and Giardia duodenalis). The characteristic of this disease are including worldwide distribution, high prevalence, and significant morbidity. Different studies relieved that the thymol content available in some medicinal plants has anti-giardiasis effect. Hence, based on adequate thymol in contents of both, Satureja sahandica and Origanum vulgare extracts, the aim of present research was comparison the effect of Satureja sahandica and Origanum vulgare Extracts with metronidazole on Giardia lamblia in vitro condition. In this experimental-laboratory study, 500 µl of each of 10, 100 and 200 mg/L concentrations of extracts and 125 mg/L of metronidazole was added to 500 µl of purified giardia cysts, respectively. In control groups normal saline used whereas these agents. The giardicidal activity of the extracts was measured 30, 60 and 120 min (s) after exposure through 0.1% eosin dye staining and microscopic enumeration method. Minimum, maximum and means lethal concentrations of treatments were calculated after three times in each group. Results relieved that anti-giardicidal effects of both extracts significantly increased due to rising the concentration and time. Based on present study findings and in accordance with others, it seems thymol content of SS and OV extracts were responsible for their anti-giardial activity. Meanwhile, further studies needed for clarify their exact mechanism of actions Manuscript profile
