Abstract

Halyomorphahalys(Stål) is a severe agricultural pest that is spreading worldwide from its original distribution in Asia. Egg parasitoids from Asia, which play a key role in the population dynamics of H.halys, are following its host along global pathways. We present the first records of Trissolcusmitsukuriiin Europe, and of Trissolcusjaponicusin Italy. Both discoveries were made in northern Italy, where H.halysis widely present and has reached extremely high population densities in some areas. Given the availability of their host, the distributions and populations of these exotic egg parasitoids are expected to expand, even in the absence of human intervention.

Review of the biology, ecology, and management of Halyomorpha halys (Hemiptera: Pentatomidae) in China, Japan, and the Republic of Korea.

J. Bergh, D. Short, Justin Joseph … (2013)

Native to China, Japan, Korea, and Taiwan, the brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) was first detected in the United States in the mid-1990s. Since establishing in the United States, this invasive species has caused significant economic losses in agriculture and created major nuisance problems for home and business owners, especially in the mid-Atlantic region. Basic and applied questions on H. halys have been addressed in its native range in Asia since the mid-1900s and the research outcomes have been published in at least 216 articles from China, Japan, and the Republic of Korea. In Asia, H. halys is described as an occasional or outbreak pest of a number of crops such as apple, pear, persimmon, and soybeans. This species is considered a nuisance pest as well, particularly in Japan. This review summarizes 100 articles primarily translated from Chinese, Japanese, and Korean to English. The content of this review focuses on the biology, ecology, and management of H. halys in Asia, with specific emphasis on nomenclature, life history, host range, damage, economic importance, sampling and monitoring tools, and management strategies. This information from the native range of H. halys provides greater context and understanding of its biology, ecology, and management in North America.

Impact of the Invasive Brown Marmorated Stink Bug in North America and Europe: History, Biology, Ecology, and Management.

Tracy C. Leskey, Anne Nielsen (2018)

The brown marmorated stink bug (BMSB), Halyomorpha halys (Stål), is an invasive pentatomid introduced from Asia into the United States, Canada, multiple European countries, and Chile. In 2010, BMSB populations in the mid-Atlantic United States reached outbreak levels and subsequent feeding severely damaged tree fruit as well as other crops. Significant nuisance issues from adults overwintering inside homes were common. BMSB is a highly polyphagous species with a strong dispersal capacity and high reproductive output, potentially enabling its spread and success in invaded regions. A greater understanding of BMSB biology and ecology and its natural enemies, the identification of the male-produced aggregation pheromone, and the recognition that BMSB disperses into crops from adjacent wooded habitats have led to the development of behavior-based integrated pest management (IPM) tactics. Much is still unknown about BMSB, and continued long-term collaborative studies are necessary to refine crop-specific IPM programs and enhance biological control across invaded landscapes.

Trissolcus japonicus (Ashmead) (Hymenoptera, Scelionidae) emerges in North America

Elijah J. Talamas, Megan Herlihy, Christine Dieckhoff … (2015)

Trissolcus japonicus (Ashmead) is an Asian egg parasitoid of the brown marmorated stink bug, Halyomorpha halys (Stål). It has been under study in U.S. quarantine facilities since 2007 to evaluate its efficacy as a candidate classical biological control agent and its host specificity with regard to the pentatomid fauna native to the United States. A survey of resident egg parasitoids conducted in 2014 with sentinel egg masses of H. halys revealed that T. japonicus was already present in the wild in Beltsville, MD. Seven parasitized egg masses were recovered, of which six yielded live T. japonicus adults. All of these were in a wooded habitat, whereas egg masses placed in nearby soybean fields and an abandoned apple orchard showed no T. japonicus parasitism. How T. japonicus came to that site is unknown and presumed accidental.
