Differential Performance of Beet Armyworm and Cabbage Looper (Lepidoptera: Noctuidae) Larvae on Selected Apium graveolens Cultivars
Three Apium graveolens (L.) varieties and cultivars within varieties were evaluated for host plant suitability to two polyphagous lepidopteran herbivores: the beet armyworm, Spodoptera exigua (Hiibner), and the cabbage looper, Trichoplusia ni (Hiibner). Overall, there were no significant differences in survivorship, developmental time, and pupal weight of S. exigua or T. ni reared on the two va...
متن کاملComparative 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 کاملDevelopment of Heterodera glycines on Soybean Damaged by Soybean Looper and Stem Canker.
Short-term greenhouse studies with soybean (Glycine max cv. Bragg) were used to examine interactions between the soybean cyst nematode (Heterodera glycines) and two other common pests of soybean, the stem canker fungus (Diaporthe phaseolorum var. caulivora) and the soybean looper (Pseudoplusia includens), a lepidopterous defoliator. Numbers of cyst nematode juveniles in roots and numbers of cys...

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...
