Temporal sampling and network analysis reveal rapid population turnover and dynamic migration pattern in overwintering regions of a cosmopolitan pest

open access: yesFrontiers in Genetics, 2022
Genetic makeup of insect pest is informative for source-sink dynamics, spreading of insecticide resistant genes, and effective management. However, collecting samples from field populations without considering temporal resolution and calculating ...

Windborne migration amplifies insect-mediated pollination services

open access: yeseLife, 2022
Worldwide, hoverflies (Syrphidae: Diptera) provide crucial ecosystem services such as pollination and biological pest control. Although many hoverfly species exhibit migratory behavior, the spatiotemporal facets of these movement dynamics, and their ...

Prediction of the Overseas Migration of the Fall Armyworm, Spodoptera frugiperda, to Japan

open access: yesInsects, 2023
(1) Background: The fall armyworm, Spodoptera frugiperda, is an invasive migratory insect pest that first arrived in Japan in early July 2019. Since then, the species has immigrated to Japan mainly in the summer monsoon season and inflicted damage mainly

Using cloud radar to investigate the effect of rainfall on migratory insect flight

open access: yesMethods in Ecology and Evolution, 2023
The fate of migrating insects that encounter rainfall in flight is a critical consideration when modelling insect movement, but few field observations of this common phenomenon have ever been collected due to the logistical challenges of witnessing these
