background : in this study, we investigated the lethal potency, electrophoretic protein pattern and in vivo effects of hottentotta saulcyi scorpion venom in mice. methods : scorpions were collected at night, by using a uv lamp from mardin province, turkey. venom was obtained from mature h. saulcyi scorpions by electrical stimulation of the telson. the lethality of the venom was determined by i....
The stemborer Sesamia nonagrioides is an important pest of maize in the Mediterranean Basin. Like other moths, this noctuid uses its chemosensory system to efficiently interact with its environment. However, very little is known on the molecular mechanisms that underlie chemosensation in this species. Here, we used next-generation sequencing (454 and Illumina) on different tissues from adult an...
(Z)-11-Hexadecenyl acetate, the main pheromone component of Sesamia nonagrioides sex pheromone, is biosynthesized from palmitic acid by Delta(11)-desaturation followed by reduction and acetylation. Production of (Z)-11-hexadecenyl acetate is regulated by the Pheromone Biosynthesis Activating Neuropeptide (PBAN). Transformation of (Z)-11-hexadecen-1-ol into the corresponding acetate is a target ...
Among the proposed mechanisms of local adaptation to different ecological environments, transcriptional changes may play an important role. In this study, we investigated whether such variability occurred within the chemosensory organs of a herbivorous insect, for which chemosensation guides most of its host preferences. A European and an African population of the noctuid Sesamia nonagrioides t...
Background Scorpions are one of the most important medical arthropods in Iran. This study aimed to determine the fauna, spatial distribution and some morphological characteristics of these venomous arthropods in the study area. Methods Scorpions were collected using Ultra Violet light, rock rolling and digging methods in West Azerbaijan, East Azerbaijan, and Ardabil Provinces during 2015-2016...
The Mediterranean corn borer, Sesamia nonagrioides Lefèbvre, is a key pest of corn and a main target of Bacillus thuringiensis (Bt) corn in Northeast Spain. Trends for future biotechnology crops indicate that Bt, non-Bt, and stacked corn varieties with metabolic pathways for vitamin-increased traits could coexist in same region. Knowledge of the oviposition response of gravid females of S. nona...
Many parasitoid species are subjected to strong selective pressures from their host, and their adaptive response may result in the formation of genetically differentiated populations, called host races. When environmental factors and reproduction traits prevent gene flow, host races become distinct species. Such a process has recently been documented within the Cotesia flavipes species complex,...
ارقام مختلف یک گیاه و یا گونه های مختلف گیاهی می توانند ازطریق صفات فیزیکی و بیوشیمیایی و یا به صورت غیر مستقیم از طریق جیره غذایی میزبان، روی ویژگی های رفتاری و کارایی دشمن طبیعی تأثیر بگذارد. این بررسی با هدف تعیین درصد پارازیتیسم و واکنش تابعی زنبور پارازیتوئید platytelenomus hylas nixon نسبت به تراکم های مختلف تخم ساقه خوار . sesamia nonagrioides lef و تعیین میزان تأثیر نوع رقم در این ویژگی...
