Longevity, duration of the oviposition period, realized fecundity, potential fecundity, and egg fertility of the beet armyworm, Spodoptera exigua (Hübner), were examined in the laboratory under three different adult diet regimes. All parameters were signiÞcantly reduced for the water-only diet compared with 10% honey or sucrose diets, except fertility, which could not be measured after 5 d beca...
life table parameters of the beet armyworm, spodoptera exigua (hã¼bner), on four sugar beet cultivars (renger, fd0005, dorothea and shirin) were studied in laboratory at 27 â± 1â°c, 60 â± 5% rh and a photoperiod of 16l: 8d hours. the larvae successfully developed on all cultivars. the shortest and longest total developmental time were recorded on fd0005 and renger, respectively. the development...
Identifying the reproductive consequences of insect migration is critical to understanding its ecological and evolutionary significance. However, many empirical studies are seemingly contradictory, making recognition of unifying themes elusive and controversial. The beet webworm, Loxostege sticticalis L. is a long-range migratory pest of many crops in the northern temperate zone from 36 °N to 5...
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...
