🎈In brown #planthoppers, transcription factors distal-less (Dll) & aristaless (al) form a cascade to regulate NlObp8: al directly binds, Dll acts indirectly. Silencing al cuts NlObp8, abolishes repellence to linalool. #Olfaction #RNAi.🔗@WileyEcolEvol

🎈New study: Sclerodermus guani wasps reared long-term on resistant hosts (Ma) outperform those from non-resistant hosts (Sp) against tough hosts—better parasitism, lower mortality, and edge in paralysis. They also prefer their rearing host. #behavior.🔗

🎈New study: The role of CYP4Gs involved in hydrocarbon formation in the survival, #reproduction (77% fewer eggs, near-zero hatching), and pyrethroid resistance of Triatoma infestans, a major Chagas disease vector. #insecticide.🔗@WileyEcolEvol

#OpenAccess research: Silencing JHAMT and JHEH genes via #RNAi harms spongy moth (Lymantria dispar) growth���lower survival, pupation/eclosion rates, developmental abnormalities. #PestControl.🔗@WileyEcolEvol

Cadmium affects two Trichogramma wasps' transgenerational traits and #host preference. T. dendrolimi fares better—making it a better #biocontrol agent for Cd-polluted sites. 🔗@WileyEcolEvol

Tropical bed #bugs (Cimex hemipterus) sense CO₂ via #antennae—ChGR2 and ChGR4 (highly expressed there) are key to the mechanism. #behavior #ecology.🔗@WileyEcolEvol

New study tested a #dsRNA variant, loop-ended dsRNA or LedRNA, for controlling a notorious #vector insect, the small brown #planthopper. LedRNA is characterized by having a loop at both ends of the dsRNA stem, resembling a close-circled RNA. @WileyEcolEvol

🎈Red imported fire ants (RIFA) crush #arthropod diversity in subtropical guava/cherimoya orchards—slashing family richness, causing taxonomic homogenization, with RIFA making up 80%+ of arthropods. #ecology.🔗@WileyEcolEvol

🚩Testing 3 dusts (Baby powder, DE, CimeXa) on tropical bed bugs (Cimex hemipterus): Both DE & CimeXa have great potential for controlling this pest (A and B), and showed a strong barrier effect (C). 🔗@WileyEcolEvol

Lepidoptera sex determination: Since 2014's #silkworm find, Masc gene is key for male development in most. Female-determining piRNAs show convergent #evolution, with diverse upstream mechanisms. #moth #butterfly #SexDetermine.@WileyEcolEvol

🎈Ostrinia furnacalis' Eiger (a TNF homolog) is a key #immune regulator: it controls IMD, Toll, NO & MAPK pathways, plus AMPs, phagocytosis & PO activity. 🔗

🚩Using a genome-wide #CRISPR cell library + JH signal reporter, key #JH signaling genes/pathways were identified. ALK studies confirm RTK-driven second messengers (Ca²⁺, IP3, DAG) and phosphorylation are critical. 🔗@WileyEcolEvol

🎈Micromus variegatus and Scymnus interruptus are solid for preventive #aphid #biocontrol (released pre-infestation): Micromus needs alternative food; Scymnus thrives with crop flowers. #OpenAccess.🔗@WileyEcolEvol

📑Eleni I. Koutsogeorgiou @ Stefanos S. Andreadis’ lab uncovers a bivoltine life cycle & regional variations in #population dynamics of invasive Halyomorpha halys in Northern Greece's kiwifruit orchards, urging tailored local #pest management strategies. 🔗

📑This study unveiled the complex roles of Helicoverpa armigera Taiman in #pupation and juvenile hormone-mediated vitellogenesis, and explored an effective #RNAi method applicable in H. armigera. #reproduction.🔗@WileyEcolEvol

📖New #Review Highlights:.1. Invertebrates’ Vago/JAK-STAT antiviral pathway parallels vertebrates’ IFN/JAK-STAT pathway. 2. Invertebrates compete with viruses for the control of the JAK-STAT pathway. #Virology #Immunology.🔗@WileyEcolEvol

📑New study explores the diet-gut microbes-insect link, showing pig manure-derived #gut #microbiota, especially Clostridium sensu stricto 1, speeds up Sarcophaga africa #development by boosting larval protein & lowering pupal glycogen. 🔗@WileyEcolEvol

🐝Chao Wen @WenChao4942, Lars Chittka @LChittka report that bumblebees prefer shorter over longer strings & connected over disconnected ones in string-pulling tasks but prioritize connectivity over spatial proximity when the two are in conflict. 🔗

📑Elena V. Burdina from Nataly E. Gruntenko’s lab report that #mating affects dopamine signaling in #Drosophila melanogaster females. #fly.🔗@WileyEcolEvol

Using Drosophila, GWAS uncovers insecticide-specific candidate genes (e.g., AstC-R1, Hr38) linked to toxicodynamics/toxicokinetics, revealing lambda-cyhalothrin resistance genotypes show less robust phenotypic responses. #Toxicology.@WileyEcolEvol
