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

Pest 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.

Can landscape management provide disease regulation services? A case study of Brazilian spotted fever incidence

Journal of Applied Ecology, Volume 63, Issue 10, October 2026.
Policy implications. Our results can help prioritize surveillance strategies and the implementation of preventive measures, particularly in areas where landscape structures cannot provide disease regulation services. Landscape management actions aimed at increasing the amount of forest areas in a more aggregated manner could help restore those ...

Assessing the Use of Oxford Nanopore Technologies Sequencing for Detection of Stable Wolbachia Bacterial Strain in Symbiosis in Wild Anopheles Mosquitoes From the WHO African Region

Environmental Microbiology, Volume 28, Issue 10, October 2026.
This study assesses Oxford Nanopore Technology sequencing to detect Wolbachia in Anopheles mosquitoes. To do this, samples were analysed using the ONT field sequencing kit and sequenced using a minION flow cell and the ONT 16S barcoding kit and Rapid barcoding kit sequenced using Flongle flow cells.
