برگ خوار چغندرقند Spodoptera exigua (Hübner) از آفات مهم گیاهان زراعی بوده و دامنه‌ی میزبانی وسیعی دارد. استفاده از حشره‌کش‌های امن تر با نحوه ی اثر متفاوت و احتمال کمتر بروز مقاومت مثل تنظیم کننده های رشد حشرات در برنامه‌های مدیریت این آفت از جایگاه ویژه‌ای برخوردار است. در این پژوهش اثر سه تنظیم‌کننده‌ی رشد حشرات به نام‌های متوکسی‌فنوزاید، لوفنوران و فلوفنوکسوران روی لاروهای سن اول برگ‌خوار چ...
متن کاملHigh Bacterial Agglutination Activity in a Single-CRD C-Type Lectin from Spodoptera exigua (Lepidoptera: Noctuidae)
Lectins are carbohydrate-interacting proteins that play a pivotal role in multiple physiological and developmental aspects of all organisms. They can specifically interact with different bacterial and viral pathogens through carbohydrate-recognition domains (CRD). In addition, lectins are also of biotechnological interest because of their potential use as biosensors for capturing and identifyin...
متن کاملGeographic Origin and Host Cultivar Influence on Digestive Physiology of Spodoptera exigua (Lepidoptera: Noctuidae) Larvae
Digestive enzymatic activity in three geographic strains (Miandiab, Kalposh and Moghan regions) of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) reared on different sugar beet cultivars (Dorothea, Rozier, Persia and Perimer) was studied under laboratory conditions (25 ± 1 °C, 65 ± 5% RH, and a photo period of 16:8 (L:D) h photoperiod).

متن کاملToxicity of Some Commonly Used Synthetic Insecticides Against Spodoptera exigua (Fab) (Lepidoptera: Noctuidae)
Spodoptera exigua (Lepidoptera: Noctuidae) is one of the major pests of many crops in Pakistan. Effectiveness of different insecticides was evaluated against field populations of 2 instar larvae of S. exigua under laboratory conditions because in lepidopterous pests resistance is developed in 3 instars. Bioassays were performed through leaf dip method to evaluate the doseand time-mortality resp...
