Characterization of Cry2Ab2 resistance in Crocidosema sp. (Lepidoptera: Tortricidae): resistance selection, inheritance, cross‐resistance patterns, and fitness costs

open access: yesPest Management Science, EarlyView.
This article reports the first characterization of Cry2Ab2 resistance in Crocidosema sp. Resistance appears to be autosomal and incompletely recessive, with a major‐gene contribution and potential involvement of additional genetic factors, and did not confer cross‐resistance to Cry1Ac or Cry1A.105. Abstract BACKGROUND The soybean bud borer, Crocidosema

Inheritance and stability of Cry2Ab2 resistance in an Ostrinia nubilalis strain originating from Wisconsin, U.S.

open access: yesPest Management Science, EarlyView.
Resistance to Cry2Ab2 protein in Ostrinia nubilalis is autosomal, functionally recessive, controlled by a single gene, and remains stable over 17 generations in the absence of Cry2Ab2 selection pressure. Abstract BACKGROUND Transgenic corn expressing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt), including Cry1Ab, Cry1Fa and/or ...

Potential distribution of Spodoptera frugiperda (J.E. Smith) in China and the major factors influencing distribution

open access: yesGlobal Ecology and Conservation, 2020
Fall armyworm, Spodoptera frugiperda (J.E. Smith) is one of the most important agricultural pests in the world. At the end of 2018, S. frugiperda was first found in Yunnan, China, and then it had spread rapidly to 19 provinces and posed a serious threat ...

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

open access: yesInsect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

open access: yesIntegrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

The Individual and Combined Entomopathogenic Activity of a Spodoptera frugiperda Multiple Nucleopolyhedrovirus and a Type I Spodoptera frugiperda Granulovirus on S. frugiperda Larvae

open access: yesViruses
The bioinsecticidal activity of several doses of a Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV-CH-32; LD10, LD50, and LD90) and a Type I Spodoptera frugiperda granulovirus (SfGV-CH13; LD50 and LD90), alone and in co-infection, was evaluated on S. frugiperda larvae.
