The common bed bugs, , and tropical bed bugs, are the primary species of public health importance in the family Cimicidae. This study aimed to determine the morphometric criteria and prevalent species of bed bugs in eastern Iran.
Bed bugs were collected from March 2021 to June 2022 from infested residential buildings and apartments in eastern Iran, including North Khorasan, Khorasan Razavi, and Sistan and Baluchistan Provinces. The morphological and morphometrical characteristics were used to identify collected bed bugs at inter- and intra-specific levels.
A total of 34 isolates comprising 127 adult bed bugs were collected from Bojnord, Mashhad, Neishabur, Taibad, Sabzevar, Kashmer, Zahedan, Saravan, Rask, Pishin and Chabahar. Of these, 33 isolates (n=124) were found to be tropical bed bugs, , and one population (n=3) was identified as . The index pronotal width/length ratio was calculated from 2.72 to 2.94 and 1.98 to 2.47 for and , respectively. The length/width ratio of the hind femur was 3.365 in and 4.267 in . The ratio of length/width of the third femur (F3 l/w) between populations of was different, and this difference was statistically significant (P< 0.05).
The results of this study indicated that was the dominant bed bug species in the east of Iran and provided more morphometric criteria of for researchers to identify the species and determine the intraspecific variations in the present and future.
温带臭虫和热带臭虫是臭虫科中对公共卫生具有重要意义的主要物种。本研究旨在确定伊朗东部臭虫的形态测量标准和优势物种。
于2021年3月至2022年6月从伊朗东部受侵扰的住宅建筑和公寓中收集臭虫，包括北呼罗珊省、呼罗珊拉扎维省、锡斯坦-俾路支斯坦省。利用形态学和形态测量学特征在种间和种内水平上鉴定所收集的臭虫。
共从博季努德、马什哈德、内沙布尔、泰巴德、萨卜泽瓦尔、卡什默尔、扎黑丹、萨拉万、拉斯克、皮申和恰巴哈尔收集了34个分离株，包含127只成年臭虫。其中，33个分离株（n = 124）被鉴定为热带臭虫，1个种群（n = 3）被鉴定为温带臭虫。温带臭虫的前胸背板宽/长比计算值为2.72至2.94，热带臭虫为1.98至2.47。温带臭虫的后股节长/宽比为3.365，热带臭虫为4.267。温带臭虫不同种群间第三股节长/宽比（F3 l/w）存在差异，且这种差异具有统计学意义（P < 0.05）。
本研究结果表明，热带臭虫是伊朗东部的优势臭虫物种，并为研究人员提供了更多热带臭虫的形态测量标准，以便在当前和未来鉴定该物种并确定种内变异。
