On the origin of the desert locust Schistocerca gregaria (Forskål) (Orthoptera: Acrididae: Cyrtacanthacridinae).
The locust genus Schistocerca (Stål) has a transatlantic disjunction, which has been controversial for more than a century. Among 50 species within the genus, only one species, the desert locust (S. gregaria Forskål), occurs in the Old World, and the rest occur in the New World. Earlier taxonomists suggested that the desert locust is a migrant from America, but this view was strongly challenged...
متن کاملفاز و بررسی‌های جدید دلایل انتشار ملخ صحرایی Schistocerca gregaria (Forskal, 1775) (Orthoptera; Cyrtacanthacridinae)
تغییر فاز ملخ صحرایی از فرم انفرادی به مهاجر در اثر استرسهای محیطی از طریق ایجاد تغییرات وراژنتیکی (اپی ژنتیک) به وجود میآید. این کاراکتر مهاجرتی با خاصیت برگشت پذیری حداکثر طی سه نسل ایجاد میشود. افزایش جمعیت، کم شدن میزبانهای گیاهی یا تخریب خرد زیستگاههای مناسب برای زندگی فاز انفرادی از عوامل مهم استرس زای محرک می باشند. تغییرات وراژنتیکی موجب تغییر مولکولی شبکه اندوپلاسمی سل...
متن کاملComparative Effects of Certain Igrs on the Carbohydrates of Hemolymph and Fat Body of the Desert Locust, Schistocerca Gregaria (orthoptera: Acrididae)
Newly molted last (5th) instar of the desert locust, Schistocerca gregaria (Forsk.), was treated through fresh plant food with 2 concentrations: high (1000.0 ppm) or low (62.5 ppm) of 3 IGRs: pyriproxyfen, tebufenozide, and lufenuron. Carbohydrate content was determined in the hemolymph and in the fat body of the early-aged, mid-aged, and late-aged 5th instar, as well as of 1and 4-d old adult f...
متن کاملPotential of the Desert Locust Schistocerca gregaria (Orthoptera: Acrididae) as an Unconventional Source of Dietary and Therapeutic Sterols
Insects are increasingly being recognized not only as a source of food to feed the ever growing world population but also as potential sources of new products and therapeutic agents, among which are sterols. In this study, we sought to profile sterols and their derivatives present in the desert locust, Schistocerca gregaria, focusing on those with potential importance as dietary and therapeutic...
متن کاملDNA damage in hemocytes of Schistocerca gregaria (Orthoptera: Acrididae) exposed to contaminated food with cadmium and lead
We measured in a comet assay the damage of DNA in the hemocytes of various stages of the grasshopper Schistocerca gregaria after exposing them to various doses of Cd and Pb in the food. The mechanisms of Cd and Pb toxicity for grasshopper are discussed. The accumulation of heavy metals and stage of the insect may play important roles in causing the DNA damage. S. gregaria may be considered a va...
