when did stink bugs come to the us
Brown marmorated stink bug Halyomorpha halys, also known as the brown marmorated stink bug (BMSB), or simply the stink bug, is an insect in the family Pentatomidae that is native to China, Japan, the Koreas, and Taiwan.[2] It was accidentally introduced into the United States, with the first specimen being collected in September 1998.[3] The brown marmorated stink bug is considered to be an agricultural pest,[4] and by 2010â€“11 had become a season-long pest in U.S. orchards.[5] Currently it is widespread in Europe, and recently has been found in South America.[6]
Bombardier beetle This reaction is very exothermic, and the released energy raises the temperature of the mixture to near 100 °C, vaporizing about a fifth of it. The resultant pressure buildup forces the entrance valves from the reactant storage chambers to close, thus protecting the beetle's internal organs. The boiling, foul-smelling liquid is expelled violently through an outlet valve, with a loud popping sound. The beetles' glands store enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. In some cases this is enough to kill a predator.[4] The main component of the beetle spray is 1,4-Benzoquinone, which is particularly irritating to the eyes and the respiratory system.
