Comparative demographic parameters of beet armyworm, Spodoptera exigua (Lep.: Noctuidae) on four commercial sugar beet cultivars
The effects of four sugar beet cultivars (Anaconda, Rozier, Evelina and Flores) on the life table parameters of beet armyworm, Spodoptera exigua (Lep.: Noctuidae) were evaluated at 26 ± 1 °C, 60 ± 5% relative humidity and a photoperiod of 16: 8 h (L: D). The highest gross and net fecundity rates were obtained on Anaconda (2573.31 ± 27.78 and 1576.31 ± 16.65 eggs/female, respectively). The net r...

پارامترهای جدول زندگی کرم برگ‌خوار چغندرقند، Spodoptera exigua (Hübner)، روی چهار رقم چغندرقند (Renger، FD0005، Dorothea و شیرین) در دمای 1 ± 27 درجه‌ی سلسیوس، رطوبت نسبی 5 ± 60 درصد و دوره‌ی نوری 16 ساعت روشنایی و 8 ساعت تاریکی تحت شرایط آزمایشگاهی تعیین شد. لاروها روی تمام ارقام به‌طور کامل رشد کردند. طولانی‌ترین و کوتاه‌ترین کل دوره‌ی رشدی به‌ترتیب روی ارقام FD0005 و Renger به‌دست آمد. شاخ...
متن کاملControl of the Beet Armyworm, Spodoptera Exigua (hübner), with Synthetic Sex Pheromone
The feasibility of synthetic sex pheromone as a communication disruption agent for the control of the beet armyworm, Spodoptera exigua (Hübner), was examined by dispensing a 7:3 mixture of (Z,E)-9, 12-tetradecadienyl acetate and (Z)-9-tetradecen-1-o1. When this mixture was dispensed into a 155 ha field, the attraction of male moths to sex pheromone traps was completely inhibited, while the dens...
متن کاملIncreased Long-Flight Activity Triggered in Beet Armyworm by Larval Feeding on Diet Containing Cry1Ac Protoxin
Evaluating ecological safety and conducting pest risk analysis for transgenic crops are vitally important before their commercial planting. The beet armyworm, Spodoptera exigua, a long-distance migratory insect pest, is not a direct target of transgenic Cry1Ac-expressing cotton in China, but nevertheless it has recently become an important pest. Migrants leaving their natal field arrive in othe...
متن کاملInfluence of diet on the larval beet armyworm, Spodoptera exigua, glucose oxidase activity
Many researchers investigating plant-insect interactions maintain their insect colonies on artificial diet and assume that salivary enzymes and elicitors remain representative of natural situations. These salivary elicitors, such as the enzyme glucose oxidase (GOX), play important roles in influencing plant defense responses. In fact, GOX has been implicated in suppressing induced nicotine-prod...
