Multiple blood feeding bouts in mosquitoes allow for prolonged survival and are predicted to increase viral transmission during dry periods

Dry conditions increase blood feeding in mosquitoes, but it is unknown if dehydration-induced bloodmeals are increased beyond what necessary for reproduction. In this study, we investigated the role of dehydration secondary behaviors mosquitoes. Following an initial bloodmeal, prolonged exposure to dry mosquitoes by nearly two-fold, and chronic allowed survive up 20 days without access water. Exposure desiccating following a bloodmeal resulted activity, decreased sleep levels, prompted return CO2 sensing before egg deposition. Increased higher survival during periods predicted pathogen transmission, allowing rapid rebound mosquito populations when favorable return. Overall, these results solidify our understanding how impact that contributes transmission dynamics.

Integrated Evaluation of Sustainability and Quality of Italian Tomato Cultivars Grown Under Irrigated and Non-Irrigated Systems

Agriculture, Journal Year: 2025, Volume and Issue: 15(4), P. 416 - 416

Published: Feb. 16, 2025

This research aimed to assess how irrigation can affect the sustainability and quality of two Italian tomato cultivars: “Riccio di Parma Casertano,” which is grown without irrigation, “Piennolo del Vesuvio DOP,” requires irrigation. Life cycle assessment water footprint analysis were used for assessment, while, content bioactive compounds was analyzed by UV-Vis spectrophotometric assays. The results indicate that ‘Riccio Casertano’ a more sustainable cultivar than ‘Piennolo DOP’, with lower environmental impacts in all 18 impact categories, showing reductions ranging from 54.55% 99.90%. higher performance Casertano” also characterized increases +32% total polyphenol +43% flavonoid as an adaptive response stress compared DOP”. However, DOP” has yield better overall nutritional functional quality, concentrations hydrophilic lipophilic compounds, such lycopene β-carotene, due results, therefore, show choice between cultivars might depend on trade-off quality. In particular, ’Riccio could excel contexts low availability while maintaining good profile synthesis compounds; other hand, offer qualities, although it needs improved agricultural practices reduce impacts.

Humidity as a zeitgeber for circadian entrainment of insect systems

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 8, 2024

Humidity levels, like light and temperature, fluctuate daily yet are less predictable; however, whether humidity entrains circadian clocks enables animals to synchronize behaviors environmental variations remains unknown. Here, we investigate the entrainment in various insects. Multiple species robustly respond cycles, when cue is removed, their rhythmic continue, suggesting that humidity-associated activities under control. Moreover,
