Triatoma infestans, Triatoma cinsine bağlı bir böcek türüdür.^[1] Arjantin, Bolivya, Uruguay ve Şili'de yaygın olarak winchuka^[2] veya vinchuca ^[3], Brezilya'da barbeiro, Venezuela'da chipo olarak da bilinen kan emici (hematofaj) böcek (Triatominae alt ailesinin hemen hemen tüm üyeleri gibi) ve Chagas hastalığına yol açabilen Trypanosoma cruzi'nin en önemli taşıyıcısıdır. Güney Amerika'nın Güney Konisi ülkelerinde yaygındır.^{[ZR 1]}

Beagle araştırma gezisi sırasında Charles Darwin, 26 Mart 1835 tarihli günlüğünde "Pampas'ın büyük kara böceği Benchuca'nın bir saldırısına uğradığını ve bu saldırının bir adı hak ettiğini yaklaşık bir inç uzunluğundaki yumuşak, kanatsız böceklerin birinin vücudunda süründüğünü hissetmek çok iğrenç; emmeden önce oldukça incedirler, ancak daha sonra yuvarlaklaşırlar ve kanla şişerler ve bu durumda kolayca ezilirler." kaydetti. Richard Keynes, bu Benchuca'yı Triatoma infestans olarak tanımlar.^[4] Darwin'in kronik Chagas hastalığından öldüğü tahmin edilmektedir.^[5]

Dağılım ve habitat[değiştir | kaynağı değiştir]

Ekolojik dağılım[değiştir | kaynağı değiştir]

Güney Amerika'da T. infestans neredeyse yalnızca ev bir türdür,^{[ZR 2]}^{[ZR 3]} özellikle Bolivya'daki Cochabamba Vadisi ile Paraguay ve Arjantin'in bazı bölgelerinde ev zararlısıdır.^{[ZR 4]}

Panstrongylus megistus, T. sordida, T. brasiliensis ve T. pseudomaculata^[6] dahil olmak üzere Chagas'ın diğer Triatominae taşıyıcılarının yerini alma eğilimindedir.^{[ZR 5]}^[6]

Coğrafi dağılım[değiştir | kaynağı değiştir]

Brezilya^{[ZR 1]} (yalnızca 1955-1964 arasında yaygın, muhtemelen güneyden Pernambuco'ya gelen göçmenler tarafından yaygın, muhtemelen iç göçle yayılmaya devam ediyor),^{[ZR 4]} El Salvador,^{[ZR 1]} Venezuela,^{[ZR 1]} Peru^{[ZR 1]} (antropik ulaşım),^{[ZR 4]} Arjantin^{[ZR 1]} (özellikle bazı bölgelerde ev zararlısı olarak),^{[ZR 4]} Paraguay (özellikle bazı bölgelerde ev zararlısı olarak).^{[ZR 4]}

Yaşam döngüsü[değiştir | kaynağı değiştir]

Dışkılama[değiştir | kaynağı değiştir]

Dışkılama, Triatominlerin T. cruzi aktarım döngüsünün merkezinde yer alır. Beslenme yoluyla doğrudan bulaşma yoktur, bunun yerine parazitlerin birikmesi kanla ilişkilidir, ancak yalnızca dışkılama ile gerçekleşir. Trumper ve Gorla 1991, bulaşmanın yayılma yoğunluğuyla ters orantılı olduğunu bulmuşlardır. Kalabalık alanlarda T. infestans birbirini kesintiye uğratma eğilimindedir ve kesintiye uğrayan beslemeler, tamamlanmış bir kan sağlamaz. T. infestans'ın doymadığında dışkılaması pek olası değildir ve bu nedenle nadiren bulaşır. Düşük yayılma yoğunluklu alanlar bu nedenle yüksek iletim oranlarına sahiptir.^[7]^[8]^[9]

In this way, man and some of his domestic animals became involved in the epidemiological chain, converting the disease into a true anthropozoonosis. The ratio of domestic and sylvatic cycles depends mainly on the species of vector involved and on the socioeconomic conditions prevalent in the new environment, which prompted Prata (178) to declare that Chagas' disease today is the result of ignorance and poverty. In some areas certain species of vector have become so adapted to the house that the transmission cycle involves only man and domestic animals, a situation that could well have existed for several centuries. In other areas sylvatic foci still exist where man is not involved, and combinations of these situations occur as well."

The southern limit of the species seems to be in the Province of Chubut, Argentina, near the 45th parallel (110), and it has been observed as high as 3682 m above sea level in that country (44).

The relationship of T. infestans with man has been longstanding; it has been recognized as a household pest in different foci, such as the Cochabamba Valley in Bolivia and some parts of Paraguay and Argentina, since the early seventeenth century (124).
