Abstract

Triatomine species (kissing bugs) infected with Trypanosoma cruzi are found across the southern United States. The northern limits of Trypanosoma cruzi infected kissing bugs are less understood. The objective of this work was to describe the locations of kissing bugs from Illinois and Missouri based on historical records, submissions to Texas A&M University’s (TAMU) Kissing Bug Community Science Program and the Centers for Disease Control and Prevention (CDC), and records from online platforms (iNaturalist, BugGuide, and GBIF) up to and including 2022. A total of 228 records were discovered, including 186 from historical or observation platforms and 42 specimens submitted to TAMU or CDC. Species included Triatoma sanguisuga (221 total records, 9 nymphs) and Triatoma lecticularia (7 records). Notably, nearly all (24/26) records submitted to TAMU were collected indoors. Twelve of the 30 (40%) specimens tested were positive for the presence of T. cruzi, including parasite discrete taxonomic units TcI and TcIV. One triatomine sample had been found in a bed feeding on the submitter; this bug was positive for T. cruzi and had evidence of human blood in its gut. Records suggest a ubiquitous distribution in Missouri and potentially to the northernmost border in Illinois. Further investigations into triatomine distribution and infection status are needed within states assumed to be northern limits in order to create public health and veterinary health messaging and baseline distributional maps from which to measure future range shifts in relation to a changing climate.

伊利诺伊州和密苏里州克氏锥虫（Kinetoplastida: Trypanosomatidae）的三足类（半翅目：Reduviidae）载体的分布：历史记录和社区科学项目提交的标本

在美国南部发现了感染克氏锥虫的三体虫（接吻虫）。人们对受克鲁兹锥虫感染的吻蝽的北部界限了解较少。这项工作的目的是根据历史记录、德克萨斯 A&M 大学（TAMU）接吻蝇群落科学项目和美国疾病控制与预防中心（CDC）提交的材料，以及在线平台（iNaturalist、BugGuide 和 GBIF）截至 2022 年（含 2022 年）的记录，描述伊利诺伊州和密苏里州接吻蝇的分布地点。共发现 228 条记录，其中 186 条来自历史或观察平台，42 条标本提交给塔姆大学或疾病预防控制中心。物种包括Triatoma sanguisuga（共221条记录，9条若虫）和Triatoma lecticularia（7条记录）。值得注意的是，几乎所有（24/26）提交给塔姆大学的记录都是在室内采集的。在检测的 30 份标本中，有 12 份（40%）对克鲁兹三螨呈阳性，包括寄生虫离散分类单元 TcI 和 TcIV。在提交者的床上发现了一个以提交者为食的三螨样本；该虫的克鲁兹疟原虫检测呈阳性，其肠道中有人类血液的迹象。记录显示，该虫在密苏里州的分布无处不在，有可能分布到伊利诺伊州的最北部边界。需要进一步调查被认为是北部界限的各州内的三蠹分布和感染状况，以便发布公共卫生和兽医卫生信息，并绘制基线分布图，据此衡量未来与不断变化的气候有关的分布范围变化。

期刊介绍： Journal of Medical Entomology is published bimonthly in January, March, May, July, September, and November. The journal publishes reports on all phases of medical entomology and medical acarology, including the systematics and biology of insects, acarines, and other arthropods of public health and veterinary significance. In addition to full-length research articles, the journal publishes Reviews, interpretive articles in a Forum section, Short Communications, and Letters to the Editor.
