Cold Hardiness in Spodoptera exigua (Lepidoptera: Noctuidae)

Environmental Entomology, 1997
The beet armyworm, Spodoptera exigua (Hubner), migrates long distances to find suitable conditions, but the possibility of its overwintering in specific hibernacula in temperate regions has been suspected. Supercooling points differed among developmental stages. Field-collected larvae had higher supercooling points than laboratory-reared larvae.

Identification of a hypertrehalosemic factor in Spodoptera exigua

Archives of Insect Biochemistry and Physiology, 2017
AbstractTrehalose is a major blood sugar in insects with a range of physiological functions, including an energy source and a cryoprotectant. Hemolymph trehalose concentrations are tightly regulated according to physiological conditions. An insulin‐like peptide, SeILP1, downregulates hemolymph trehalose concentrations in Spodoptera exigua.

Biochemical mechanisms for metaflumizone resistance in beet armyworm, Spodoptera exigua

Pesticide Biochemistry and Physiology, 2014
The metaflumizone, which belongs to the class of voltage-dependent sodium channel blockers, was registered to control Spodoptera exigua on vegetables in China in 2009. The present study revealed S. exigua has developed high resistance to this novel chemistry insecticide shortly after 2-3 years application in Guangdong Province of China.

A novel Cry9Aa with increased toxicity for Spodoptera exigua (Hübner)

Journal of Invertebrate Pathology, 2014
Cry9Aa, produced by Bacillus thuringiensis is reported to be not active against Spodoptera exigua (beet armyworm). In this study we have cloned a new cry9Aa5 gene encoding a protoxin with increased activity against S. exigua as compared to Cry9Aa1. When aligned to Cry9Aa1, four amino acid substitutions in domain I and one substitution in the C-terminal

Susceptibility of Spodoptera exigua to 9 toxins from Bacillus thuringiensis

Journal of Invertebrate Pathology, 2008
Nine of the most common lepidopteran active Cry proteins from Bacillus thuringiensis have been tested for activity against Spodoptera exigua. Because of possible intraspecific variability, three laboratory strains (FRA, HOL, and MUR) have been used. Mortality assays were performed with the three strains.

Biodiversity of the microbiota inSpodoptera exigua(Lepidoptera: Noctuidae)

Journal of Applied Microbiology, 2019
Spodoptera exigua is a serious pest of many agricultural crops. However, the bacterial communities of S. exigua are poorly studied, particularly over their entire life cycle. We aimed to study the biodiversity of the microbiota across the life cycle of S.
