Journal ArticleDOI
Collapse of Insect Gut Symbiosis under Simulated Climate Change
Yoshitomo Kikuchi,Akiyo Tada,Dmitry L. Musolin,Nobuhiro Hari,Takahiro Hosokawa,Kenji Fujisaki,Takema Fukatsu +6 more
TL;DR: An experimental demonstration that global warming can affect a pest insect via suppression of its obligate bacterial symbiont, highlighting that heat-susceptible symbionts can be the “Achilles’ heel” of symbionT-dependent organisms under climate change conditions.
Journal ArticleDOI
Too hot to handle? Phenological and life-history responses to simulated climate change of the southern green stink bug Nezara viridula (Heteroptera: Pentatomidae)
TL;DR: It is concluded that even a moderate temperature increase in the future is likely to have a complex influence upon insects, strongly affecting many of their life-history and phenological parameters.
Journal ArticleDOI
Some like it hot! Rapid climate change promotes changes in distribution ranges of Nezara viridula and Nezara antennata in Japan
TL;DR: All the climatic data suggest that over the last 45 years, environmental conditions have become more favourable for overwintering of N. viridula at many locations in central Japan, representing a direct response to climate warming.
Journal ArticleDOI
Egg Laying Preference, Larval Dispersion, and Cannibalism in Helicoverpa armigera (Lepidoptera: Noctuidae)
TL;DR: It is suggested that cannibalism is a behavior of larval H. armigera that has evolved to remove potential intraspecific competitors and thus to avoid unsuitable conditions.
Journal ArticleDOI
Obligate association with gut bacterial symbiont in Japanese populations of the southern green stinkbug Nezara viridula (Heteroptera : Pentatomidae)
Akiyo Tada,Yoshitomo Kikuchi,Takahiro Hosokawa,Dmitry L. Musolin,Kenji Fujisaki,Takema Fukatsu +5 more
TL;DR: It is reported that N. viridula from Japanese populations consistently harbors the same gammaproteobacterial gut Symbiont, but, in contrast with previous work, experimental sterilization of the symbiont resulted in severe nymphal mortality, indicating an obligate host–symbiont relationship.
