where did all the stink bugs come from
Brown marmorated stink bug Halyomorpha halys, also known as the brown marmorated stink bug (BMSB), 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 an agricultural pest[4] and by 2010â€“11 had become a season-long pest in U.S. orchards.[5] It has recently established itself in Europe and South America.[6]
Petrichor The term was coined in 1964 by two Australian CSIRO researchers, Isabel Joy Bear and Richard G. Thomas, for an article in the journal Nature.[1][2] In the article, the authors describe how the smell derives from an oil exuded by certain plants during dry periods, whereupon it is absorbed by clay-based soils and rocks. During rain, the oil is released into the air along with another compound, geosmin, a metabolic by-product of certain actinobacteria, which is emitted by wet soil, producing the distinctive scent; ozone may also be present if there is lightning.[3] In a follow-up paper, Bear and Thomas (1965) showed that the oil retards seed germination and early plant growth.[4]
