DOI: 10.1002/arch.70027

Abstract: ABSTRACT This study evaluates the efficacy of Spodoptera littoralis nucleopolyhedrovirus (SpliNPV) and laboratory‐synthesized carbon quantum dot nanoparticles (CQDNPs) against the second instar Spodoptera littoralis larvae under laboratory and greenhouse conditions. Individually, both SpliNPV and CQDNPs… read more here.

DOI: 10.1002/ps.7338

Abstract: BACKGROUND In the search for alternative tools for integrated pest management, azadirachtin, a botanical insecticide, has been used with the most promising activity against Spodoptera spp., but the mechanism of cytotoxicity on reproductive organs remains… read more here.

DOI: 10.1002/ps.7466

Abstract: BACKGROUND Telenomus remus (Nixon) is a dominant natural enemy controlling the invasive pest Spodoptera frugiperda (J. E. Smith). Continuous rearing of egg parasitoids on alternative hosts is crucial for mass production and cost reduction. However,… read more here.

DOI: 10.1002/ps.8427

Abstract: BACKGROUND The F116V mutation in the substrate recognition site 1 (SRS1) of Spodoptera exigua CYP9A186 has been demonstrated to confer ~200-fold resistance to emamectin benzoate (EB). In this study, a novel mutation (F116I) in CYP9A25,… read more here.

DOI: 10.1016/j.jip.2020.107340

Abstract: Vip3Aa protein is produced by Bacillus thuringiensis during vegetative growth and displays high toxicity against a wide range of lepidopteran insect larvae such as Spodoptera exigua and Spodoptera frugiperda, both important insect pests worldwide. Vip3Aa… read more here.

DOI: 10.1016/j.ympev.2021.107161

Abstract: The noctuid genus Spodoptera currently consists of 31 species with varied host plant breadths, ranging from monophagous and oligophagous non-pest species to polyphagous pests of economic importance. Several of these pest species have become major… read more here.

DOI: 10.1017/s000748532200030x

Abstract: Abstract Understanding predator–prey interactions is essential for successful pest management by using predators, especially for the suppression of novel invasive pest. The green lacewing Chrysopa formosa is a promising polyphagous predator that is widely used… read more here.

DOI: 10.1073/pnas.2402045121

Abstract: Significance The genetic factors that influence diet breadth in herbivorous insects remain poorly understood. Here, we demonstrate that uridine diphosphate (UDP)-glycosyltransferase (UGT) genes play a key role in the capacity of species within the Spodoptera… read more here.

DOI: 10.1093/jee/toad073

Abstract: The fall armyworm (FAW) Spodoptera frugiperda was first found in China in 2018. In other countries, FAW has evolved corn and rice strain biotypes. It is not possible to identify these strains based on morphology.… read more here.

DOI: 10.1093/jee/toae083

Abstract: Insecticides prevent or reduce insect crop damage, maintaining crop quality and quantity. Physiological traits, such as an insect's feeding behavior, influence the way insecticides are absorbed and processed in the body (toxicokinetics), which can be… read more here.
