چکیده بررسی جدول زندگی و پارامترهای زیستی بالتوری سبز chrysoperla carnea (stephen) (neuroptera: chrysopidae) برروی سه گونه شته در شرایط آزمایشگاهی به کوشش میلاد فرخی شکارگر عمومی بالتوری سبز با نام علمی chrysoperla carnea (stephens) (neuroptera: chrysopidae) به عنوان یکی از مشهورترین عوامل کنترل بیولوژیک مطرح است. در این مطالعه تاثیر سه گونه رژیم غذایی شامل شته های schizaphis gramin...
The 579-nucleotide 5' untranslated region (5'UTR) of the Rhopalosiphum padi virus (RhPV) possesses a cross-kingdom internal ribosome entry site (IRES) activity that functions in insect, mammalian, and plant-derived in vitro translation systems, and six TAAG motifs within the DNA fragment encoding the RhPV 5'UTR were previously found to confer the RhPV 5'UTR with late promoter activity in baculo...
Local generalist predators can be exploited in conservation biological control of agricultural pests. To conserve and promote the most important predators, it is critical to have detailed knowledge about their prey range under natural conditions. I have studied predator-prey interactions between lycosid spiders from the genus Pardosa and a major aphid pest in spring-sown cereals; Rhopalosiphum ...
The presence of glutathione transferases and esterase activity was investigated in Rhopalosiphum padi and the effects of the cereal hydroxamic acid, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) on these detoxification enzymes was studied. Activity of glutathione S-transferases and general esterases was determined for adult aphids feeding on a natural diet lacking DIMBOA and on an artif...
فون شته های خانواده Aphididae روی میزبان های مختلف گیاهی در شهرستان کرمانشاه طی سال های 1389 تا 1390 بررسی شد. شته های جمع آوری شده از روی میزبان های گیاهی در الکل اتیلیک 75 درصد نگهداری و پس از تهیه پرپاراسیون تا سطح گونه شناسایی شدند. علاوه بر این میزبان های گیاهی گونه ها به منظور کمک به شناسایی گونه های شته جمع آوری و توسط متخصصین گیاه شناس شناسایی شد. گونه های شته شناسایی شده ب...
In a study of aphids and their parasitoids in wheat fields of Shiraz region, the species composition, distribution and seasonal dynamics of the dominant species were monitored during 2004-5.Collections were made from 1-3 hectare fields in 10 locations within 50 Km radius around Shiraz city. Species density was estimated by counting individuals present on 40 winter wheat tillers taken at random ...
