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...

Projecting Overwintering Regions of the Beet Armyworm, Spodoptera exigua in China using the CLIMEX Model

The beet armyworm, Spodoptera exigua Hübner (Lepidoptera: Noctuidae) is a serious agricultural pest worldwide. However, population sources of S. exigua in outbreak regions are still vague due to the lack of understanding the distribution of overwintering regions, especially in China. In the present study, the potential overwintering regions of S. exigua in China are projected using the method o...

RNA interference of glycerol biosynthesis suppresses rapid cold hardening of the beet armyworm, Spodoptera exigua.

The beet armyworm, Spodoptera exigua, is a freeze-susceptible species that overwinters in temperate zones without diapause. A rapid cold hardening (RCH) and supercooling capacity usually play crucial roles in survival during the overwintering period. This study identified a cryoprotectant as a RCH factor of S. exigua. Pre-exposure of S. exigua larvae to 4°C significantly increased survival at -...

Influence 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...

Trans-regional migration of the beet armyworm, Spodoptera exigua (Lepidoptera: Noctuidae), in North-East Asia

The beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), is a serious polyphagous insect pest worldwide. This species is known as a long-distance migrant, and previous studies on its migration have been mostly carried out in regions where it can overwinter. However, what pattern of seasonal migration this species exhibits in regions where it cannot overwinter (i.e., the 'summer b...
