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...
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 کاملField and Laboratory Performance of Novel Insecticides against Armyworms (lepidoptera: Noctuidae)
Beet armyworm, Spodoptera exigua (Hübner), and fall armyworm, Spodoptera frugiperda (J. E. Smith), are occasional pests of cotton, Gossypium hirsutum (L.), and soybean, Glycine max (L.) Merrill. These insects can be difficult to control due to insecticide resistance and larval behavior on plants. The objectives of these studies were to determine the efficacy of selected insecticides against nat...
متن کاملTranscriptome Analysis and Screening for Potential Target Genes for RNAi-Mediated Pest Control of the Beet Armyworm, Spodoptera exigua
The beet armyworm, Spodoptera exigua (Hübner), is a serious pest worldwide that causes significant losses in crops. Unfortunately, genetic resources for the beet armyworm is extremely scarce. To improve these resources we sequenced the transcriptome of S. exigua representing all stages including eggs, 1(st) to 5(th) instar larvae, pupae, male and female adults using the Illumina Solexa platform...
متن کاملComparative life table parameters of beet armyworm, Spodoptera exigua (Lep.: Noctuidae), on four commercial sugar beet cultivars
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...
