Flight direction is a major component of an animal's migratory success. However, few studies have focused on variation in flight direction both between and within individuals, which is likely to be correlated with other traits implied in migration processes. We report patterns of intra- and inter-individual variation in flight direction in the large white butterfly Pieris brassicae. The presenc...
The cultivation of cruciferous crops is threatened by extensive yield losses caused the soil-borne pathogen Plasmodiophora brassicae Woronin, 1877. objective study was to assess potential bacterial product BactoMix 5 for control clubroot on a naturally infested soil in growth chamber trials using P. brassicae-specific qPCR methodology. results did not show significant decrease nor reduction dis...
Plants release volatiles induced by herbivore feeding that may affect the diversity and composition of plant-associated arthropod communities. However, the specificity and role of plant volatiles induced during the early phase of attack, i.e. egg deposition by herbivorous insects, and their consequences on insects of different trophic levels remain poorly explored. In olfactometer and wind tunn...
Plasmodiophora brassicae causes clubroot, a major disease of Brassica oil and vegetable crops worldwide. P. brassicae is a Plasmodiophorid, obligate biotrophic protist in the eukaryotic kingdom of Rhizaria. Here we present the 25.5 Mb genome draft of P. brassicae, developmental stage-specific transcriptomes and a transcriptome of Spongospora subterranea, the Plasmodiophorid causing powdery scab...
Mitogen-activated protein kinase (MAPK or MPK) cascades play key roles in responses to various biotic stresses, as well as in plant growth and development. However, the responses of MPK and MPK kinase (MKK) in Chinese cabbage (Brassica rapa ssp. pekinensis) to Plasmodiophora brassicae, a causal agent of clubroot disease in Brassica crops, are still not clear. In the present study, a total of 11...
The hypertrophy and hyperplasia of infected roots into clubs are the intrinsic characteristics of clubroot, one of the economically most important diseases in Brassica crops worldwide. Polyamines, arginine (Arg)-derived metabolites, have long been recognized as cell proliferation and differentiation regulators in plants and consequently are suitable candidates for potential gall development fac...
چکیده اکثر آفت کش های مدرن، زیست کش های عمومی بوده و برای انسان و تعداد زیادی از موجودات غیر هدف، سمی هستند. علاوه بر اثرات بلند مدتی که روی سلامتی انسان دارند، ایجاد مقاومت در آفات، مسمومیت جانوران اهلی، زنبور عسل و سایر گرده افشان ها، حیات وحش و دشمنان طبیعی آفات نیز باعث می شوند. زنبور تریکوگراما brassicae trichogramma یکی از دشمنان طبیعی آفات کلیدی چون کرم سیب، کرم ساقه خوار برنج، کرم گلو...
تغییرات فصلی جمعیت تخم سوسک برگخوار نارون xanthogaleruca luteola در سال 1379 در نارون کاریهای کرمان مورد بررسی قرار گرفت . میانگین تعداد تخم در هر برگ نارون در فصل بهار و تابستان به ترتیب 1/7-+0/34 و 0/86-+0/3 عدد و میانگین آن در طول کل فصل رویشی درخت نارون برابر 1/30-+0/233 در هر برگ بود. پارازیتیسم تخمهای سوسک برگخوار نارون توسط زنبور tetrastichus gallerucae از تاریخ 78/2/6 به میزان 12/48 درص...
learning ability and memory duration are two inseparable factors which can increase theefficiency of a living organism during its lifetime. trichgramma brassice bezdenko (hym.:trichogrammatidae) is a biological control agent widely used against different pest species.this research was conducted to study the olfactory associative learning ability and memoryduration of t. brassicae under laborato...
