Over-sea dispersal and salt tolerance
In order to evaluate whether the flightless Pachyrhynchus weevils can colonize different islands across the ocean, the salinity tolerances of egg, larva and adult weevils were tested under salty water, including a field experiment to allow the insects rafting on the real Kuroshio Currrent on the ocean. This study showed that eggs and larvae might be the most probable stage to cross the oceanic barrier (Yeh et al. 2018). This study was reported by The Economist (https://www.economist.com/science-and-technology/2018/11/01/how-flightless-beetles-wander-the-pacific) and JEB (http://jeb.biologists.org/content/221/24/jeb195792)
The basic ecology of Pachyrhynchus weevils regarding to the life history and captive-breeding technique of some Pachyrhynchus weevils was also reported by our team (Hsu et al. 2017, Huang et al. 2018)
