“…The high gene flow maybe due to the transportation of fresh vegetable from south to north in China, such as from Anhui Province to Zhejiang Province. The passive transportation accelerates gene flow among different populations (Martinez-Hernandez et al, 2021). The high geneflow, however, may be the evidence of its migration (Seymour et al, 2016;Yang et al, 2020).…”

The striped flea beetle (SFB) Phyllotreta striolata (Fabricius) (Coleoptera: Chrysomelidae) is a major pest of cruciferous vegetables in southern China. The population diversity and genetic structure of SFB are unknown. Here, we assembled a draft genome for the SFB and characterized the distribution of microsatellites. Then, we developed 12 novel microsatellite markers across the genome. We used a segment of the cox1 gene and newly developed microsatellite markers to genotype the genetic diversity of SFB across southern China. There were 44 mitochondrial haplotypes in the SFB populations, with haplotype 2 as the most widespread. The population genetic differentiation was very low, indicated by FST-values (<0.05 except for Guangxi population with other populations based on cox1), high gene flow (4.10 and 44.88 of cox1 and microsatellite, respectively) and Principal Coordinate Analysis across all populations. Mantel test showed genetic distance in SFB was significantly associated with geographic distance based on microsatellites (R2 = 0.2373, P = 0.014) while result based on cox1 (R2 = 0.0365, P = 0.155) showed no significant difference. The phylogenetic analysis did not find any geographically related clades among all haplotypes. Analyses based on microsatellites showed a lack of population genetic structure among all populations. Our study provides a foundation for the future understanding of the ecology and evolution of SFB and its management.

“…Both Triatoma barberi (Usinger) and Triatoma longipennis (Usinger) (Hemiptera: Reduviidae: Triatominae) are considered important vectors of T. cruzi in Mexico, due to their presence in domestic and peridomestic habitats, their wide geographic distribution and their high infection rate (Brenière et al, 2010;Martinez-Hernandez et al, 2021;Rivas et al, 2018;Salazar Schettino et al, 2005). Similar to most reduviids, both species have five nymphal stages in addition to the adult stage, and males and females of all stages can be infected with T. cruzi, and transmit Chagas disease (Velásquez-Ortiz et al, 2022).…”

“…Although the effects of T. cruzi on the development and survival of different species of triatomine bugs are known, it is not fully understood how the parasite affects many of the species that inhabit Mexico, such as T. barberi, one of the principal species that transmits the parasite (Rivas et al, 2018). Hence, this study aimed to know if T. cruzi affects the survival and development of this species, both males and females, comparing it with T. longipennis, the latter is one of the most abundant in Mexico (Brenière et al, 2010;Martinez-Hernandez et al, 2021).…”

Triatomines are insect vectors of the flagellate protozoan Trypanosoma cruzi, the causative agent of Chagas disease. This occurs when the triatomine defecates on the skin of the vertebrate host when it bites its host for feeding. This lesion causes the penetration of T. cruzi, whose infective phase is the tripomastigote, and the non-infective replicative phase epimastigote. Although the effects of T. cruzi on the development and survival of different species of triatomine bugs are known, it has not been fully described how the parasite affects many of the species that inhabit Mexico. Therefore, the present study aimed to investigate the effect of the presence of T. cruzi on triatomine development and survival. For this, five triatomines of each instar of each species, Triatoma barberi and Triatoma longipennis, were inoculated, from their second instar to their adult stage, female or male. Each triatomine was infected with 3-5 x105 parasites and they were incubated for 100 days and the kinetic of parasites in the feces and T. cruzi phases were recorded. The results showed that T. barberi and T. longipennis development was affected in all stages because of T. cruzi infection. It was greater for T. longipennis, both in its mortality, as well as time to molt in each phase.

“…Triatoma longipennis, Usinger, 1939 (formerly called Meccus longipennis ) is considered the main species responsible for the transmission of T. cruzi in northern, western, and central Mexico 7 . Its current geographical distribution includes 10 of 32 Mexican states: Aguascalientes, Chihuahua, Colima, Durango, Guanajuato, Jalisco, Michoacan, Nayarit, Sinaloa, and Zacatecas 8 . This triatomine species is considered peridomiciliary, with percentages of natural infections ranging between 21.7% and 33.3% in different regions 9 .…”

Background: We report the presence of Triatoma longipennis for the first time in two localities in Hidalgo, Mexico. Methods: This study was conducted at Tecozautla municipality, Hidalgo. Collection was performed in April 2022. Results: We collected eight triatomines from Guadalupe: two fourth-instar nymphs, three fifth-instar nymphs, one female, and two males. In San Miguel Caltepantla, a female was collected inside a dwelling. One sample tested positive for Trypanosoma cruzi . Conclusions: These findings suggest the need to investigate the dynamics of this species with respect to the inhabitants of the study area.
