Abundant Aedes (Stegomyia) aegypti aegypti mosquitoes in the 2014 dengue outbreak area of Mozambique [PDF]

open access: yes, 2015
In early 2014, dengue cases were reported from northern Mozambique, 30 years after the last outbreak. We identified potential dengue vector species in three northern towns, Pemba, Nampula and Nacala, and one southern town, Maputo, during the outbreak in ...

Virus‐specific alterations in placental structure and transporter expression following maternal arbovirus infection

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Arboviruses induce virus‐specific alterations in placental structure and functional markers. Chikungunya virus (CHIKV) exposure was associated with reduced syncytiotrophoblast and syncytial knot areas, increased cytotrophoblast proliferation (Ki‐67) and thyroid transporter (MCT8) expression, reduced protective (P‐gp and BCRP ...

Garlic‐Derived Behavioural Deterrents: Diallyl Disulfide and TrpA1‐Mediated Suppression of Insect Reproduction

open access: yesModern Agriculture, Volume 4, Issue 2, December 2026.
Garlic‐derived diallyl disulfide acts as a behavioural deterrent that suppresses insect mating and oviposition through sensory pathways. The compound is detected through gustatory mechanisms involving the transient receptor potential A1 (TrpA1) channel and neural responses.

DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

open access: yesPest Management Science, Volume 82, Issue 10, Page 9653-9665, October 2026.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

Simulated climate change, but not predation risk, accelerates Aedes aegypti emergence in a microcosm experiment in western Amazonia.

open access: yesPLoS ONE, 2020
Climate change affects individual life-history characteristics and species interactions, including predator-prey interactions. While effects of warming on Aedes aegypti adults are well known, clarity the interactive effects of climate change (temperature

Identification of broadly expressed nervous system‐related genes as effective RNAi targets in the brown marmorated stink bug, Halyomorpha halys

open access: yesPest Management Science, Volume 82, Issue 10, Page 9870-9878, October 2026.
Broadly expressed genes outperformed brain‐enriched neural targets as RNAi candidates in Halyomorpha halys. Microinjection of dsRNA targeting alpha‐soluble NSF attachment protein (Asnap) or Ras opposite protein (Rop) caused strong feeding suppression and near‐complete mortality, identifying them as promising targets for future oral or spray‐based RNAi ...
