    Wolbachia is a genus of Rickettsia-like bacteria that infects a broad range of insect species throughout the world. It often influences host reproduction to facilitate its transmission to their offspring and spread through populations. The occurrence and ecology of Wolbachia has not been surveyed in detail in Thai butterflies. In this study, we conduct the first systematic survey of Wolbachia infection by sampling 623 specimens from 46 butterfly species from 5 families obtained from tropical forests in 3 geographic regions of Thailand. Wolbachia infections were detected using three PCR primer sets: 16S rRNA, ftsZ and wsp. The results showed evidence for widespread Wolbachia infection in Thai butterflies. The Wolbachia presence was confirmed in 291 individuals from 17 butterfly species of 2 families, comprising 86 individuals from the Central Region (32 males and 54 females), 72 individuals from the Northeast Region (25 males and 47 females), and 133 individuals from the West Region (46 males and 87 females). This report will be useful for understanding the distribution of Wolbachia in butterflies from Thailand.

    Members of the genus Wolbachia are a group of Rickettsia-like, intracellular, maternally inherited bacterial endosymbionts that infect a diverse range of insects and cause reproductive changes in their hosts. Although Wolbachia's role in many insects has been extensively studied, only a little of their effects on host's reproduction and their infection frequencies were reported in Lepidopteran which is one of the most diverse insects. Here, we present the first systematic survey of the Wolbachia infection status in different species of moths from three different geographic regions of Thailand, which was carried out during January to December in 2019 with the screening of 1,235 specimens in total of 58 moth species from 13 families. Specimens were collected from Khao Yai National Park (the Central and the Northeast regions), and Kaeng Krachan National Park (the West region). Infections of Wolbachia were screened by using polymerase chain reaction with 16S rRNA, ftsZ and wsp gene primers which the results indicated high rates of Wolbachia infection in moth populations from Thailand. Wolbachia was found in all different geographically populations in total of 625 individuals in total of 28 moth species from 9 families, including 144 individuals (46 males and 98 females) from the Central, 156 individuals (49 males and 107 females) from the Northeast, and 325 individuals (114 males and 211 females) from the West. The highest infection rate was 90.47% in the West populations and the average infection rate was 61.90%. The detection of Wolbachia in different moth populations from all regions was identical when all primers were used to screen for Wolbachia. The relative densities of Wolbachia within each individual were determined using quantitative real-time PCR and the result showed that there was a low Wolbachia infection density in these moth populations. These findings indicated that Wolbachia are distributed throughout the moth populations from Thailand.
