Accurate species identification of horse flies (Diptera: Tabanidae) is crucial due to their role as vectors for various pathogens, which is essential for understanding their biology, devising strategies to control their populations, and enhancing disease surveillance. This study assessed the efficacy of outline-based geometric morphometrics (GM) by analyzing the wing cell contours of discal, first submarginal, and second submarginal cells to distinguish three morphologically similar species commonly found in Thailand, , , and . Statistical analysis demonstrated significant size differences between and the two other species ( < 0.

The blood-sucking flies of the genus Geoffroy, 1762 (Diptera: Muscidae) are significant ectoparasites that can cause irritation and transmit pathogens to both animals and humans. Within the genus , two species, and , have similar morphology and coexist in the same habitat. Accurate species identification of these flies is crucial for understanding disease vectors and implementing effective control measures.

The flies of the genus Geoffroy, 1762 (Diptera: Muscidae), are regarded as pests of veterinary and medical importance. In Thailand, (Linnaeus, 1758) is the most abundant species and is widely distributed throughout the country. This species can coexist with two other morphologically similar species: Picard, 1908, and Rondani, 1873.

The stable fly, (Diptera: Muscidae), and the horse fly, (Diptera: Tabanidae), are important ectoparasites of livestock in Thailand. These species affect animal health and cause economic losses. This study investigated the insecticidal activity of essential oil against and through contact and fumigant toxicity tests and evaluated the effects of the essential oil on these flies through histopathological and scanning electron microscopic (SEM) studies.

Synanthropic rodents are important urban pests that frequently carry hematophagous ectoparasites. These blood-sucking pests are capable of transmitting epizootic and zoonotic pathogens by landing on one host after feeding on an infected animal. This study aimed to estimate the prevalence of ectoparasites carried by synanthropic rodents and discuss the pathogens that are associated with these external parasites.

A survey of ectoparasites on rodents was carried out bimonthly from April 2008 to March 2009 in 3 districts of Sukhothai Province, northern Thailand. A total of 130 rodents comprising 8 species of hosts were captured and examined for ectoparasites. The hosts examined were Bandicota indica, Bandicota savilei, Rattus losea, Rattus rattus, Rattus exulans, Rattus norvegicus, Menetes berdmorei and Tamiops mcclellandii.
