In 1980-1983 small-scale tests were conducted and background information was obtalned to determine the feasibility of developing a quarantine treatment with methyl bromide (MB) for the codling moth (Cydia pomonella La) infesting in-shall walnuts. Some of the studies conducted at this time included basic dose mortality responses of diapausing and nondiapausing larvae, residue determinations and ...
برای بررسی دوشکلی جنسی کرم سیب، افراد نر و ماده در قالب 9 جمعیت جغرافیایی از چهار استان شمال غرب کشور شامل آذربایجان شرقی، آذربایجان غربی، اردبیل و زنجان در پاییز سال 1382 جمع آوری شد. با تبدیل مختصات هندسی لندمارک ها به متغیرهای شکلی، تعداد 26 و 18 متغیر شکلی به ترتیب برای بال های جلو و عقب حاصل گردید. برای این متغیرها، rwa انجام و حدود نهایی تغییرات بال در دو جنس تعیین شد. پس از محاسبه ی اندا...
A method for screening codling moth granulovirus (CpGV) formulation sensitivity to sunlight using specially prepared half apples and a solar simulator is described. The half apple preparation allows an even coverage of virus over the surface of the fruit that would not be possible using whole apples. Leaves and artificial medium were not usable for extended periods of exposure in the solar simu...
The codling moth (Cydia pomonella) is probably the most harmful pest in apple and pear orchards. crop loss due to high harmfulness of insect can be extremely expensive; therefore, sophisticated management necessary protect crop. conventional monitoring approach for swarming has been based on traps that are periodically checked by human operators. However, this workflow automatized. To achieve g...
We attempted to search novel Bacillus thuringiensis strains that produce crystals with potential utility in plant protection and with higher activity than strains already used in biopesticide production. Seven B. thuringiensis soil and water isolates were used in the research. We predicted the toxicity of their crystals by cry gene identification employing PCR method. The isolate MPU B63 with i...
