A potent Vip3Aa94 protein from Thai Bacillus thuringiensis: molecular characterization and insecticidal potential [PDF]

PeerJ
Vegetative insecticidal proteins (Vip) are produced by Bacillus thuringiensis during its vegetative growth stage. Vip3 proteins play a significant role in the insecticidal activity of B.

Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle

Integrative Zoology, EarlyView.
Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.

Conserved dimerization architecture in C‐type lectins from virus‐vector mosquitoes

The FEBS Journal, EarlyView.
C‐type lectins (CTLs) are involved in the detection of viral/microbial carbohydrates. We studied a family of soluble CTLs in the mosquito Aedes aegypti, which acts as a vector for viruses like dengue and Zika. Using crystallography, biophysics, and structure prediction approaches, we found that these proteins consistently pair together in the same ...

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Modulation of antiviral immunity by the ichnovirus HdIV in Spodoptera frugiperda

Molecular Immunology, 2019
Polydnaviruses (PDVs) are obligatory symbionts found in thousands of endoparasitoid species and essential for successful parasitism. The two genera of PDVs, ichnovirus (IV) and bracovirus (BV), use different sets of virulence factors to ensure successful parasitization of the host.

Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in cotton: vertical distribution of egg masses, effects of adult density and plant age on oviposition behavior

Arquivos do Instituto Biológico
The objective of this work was to determine the most suitable density of adults per plant, ideal plant age, and vertical distribution of eggs in different parts of the plant in a greenhouse investigation for future resistance studies and improvement of S.

RNA activation in insects: From emerging evidence to molecular applications

Insect Molecular Biology, EarlyView.
Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.
