e emergence of pyrethroid resistance in Phlebotomus sand ies is an urgent issue for vector control using indoor residual spraying (IRS). Two amino acid substitutions at codon 1014 (L1014F and L1014S) in the voltage-gated sodium channel (VGSC) gene have been reported in Phlebotomus argentipes, a major vector of visceral leishmaniasis (VL). Known as “knockdown resistance (kdr),” these substitutions confer pyrethroid resistance in various insect species. e frequency of the VGSC mutant allele was investigated in Phlebotomus and Sergentomyia species at two di erent IRS regimes: “long-term treated,” 12 rounds for seven years in Mymensingh, Bangladesh; “short-term treated,” four rounds for two years in Pabna, Bangladesh. In Mymensingh, the L1014F/S allele frequency was 100% in P. argentipes and 98% in S. babu babu. In Pabna, the frequency was 41% in P. argentipes. At other kdr sites (codons 1011, 1016, and 1020), the genotypes of all specimens in Bangladesh were wild-type homozygotes. is study showed that a long and frequent exposure to IRS is crucial for the development of genetic mutations in VGSCs, a higher kdr frequency, and pyrethroid resistance in Phlebotomus.

: Surveillance of vector mosquitoes has been conducted in Tokyo since 2004, and Aedes albopictus and Culex pipiens complex were identified as the dominant and widely-distributed species in Tokyo Metropolis. We performed PCR-based identification of the Cx. pipiens complex that we collected using CO 2 baited-traps from 25 sites in Tokyo Metropolis area between 2018 and 2019. In 2019 mosquito larvae were collected from catch basins at 9 sites, reared to adult, and a part of the emerged Cx. pipiens comlex were identified by PCR-based method. As a result, Cx. quinquefasciatus and the hybrids between Cx. quinquefasciatus and Cx. pipiens complex (excluding Cx. quinquefasciatus ) were identified in Tokyo Metropolis area for the first time. Continuous field survey is required whether Cx. quinquefasciatus have already been distributed or not in Tokyo Metropolis.

e increase in the number of imported cases of dengue fever in Japan is of particular concern as Aedes albopictus is a vector of dengue fever. Due to the potential for insecticide resistance and the impact of insecticides on non-target species, increased attention is being paid to alternative methods of pest control. Placing salt in used tires has been recommended by the Ministry of Health, Labor and Welfare in Japan as a means of controlling mosquitoes. However, the e ectiveness of salt as a larvicide against Ae. albopictus are currently unclear. is study examined the acute toxicity of sodium chloride against rst and fourth larval instars of Ae. albopictus. Acute toxicity tests were conducted according to World Health Organization guidelines. e susceptibility of Ae. albopictus larvae was tested against 0.25%, 0.5%, 0.75%, 1.00%, 1.25% and 1.5% NaCl solutions. Larval mortality was correlated with an increase in NaCl concentration and exposure duration. First instar Ae. albopictus larvae were more sensitive to NaCl than fourth instar, and 72-h LC90 values for rst and fourth larval instars were 0.49% and 1.01% NaCl, respectively. Our results suggest that the application of 0.5% NaCl to a habitat for 3 days is e ective for Ae. albopictus

We report the results of mosquito inspection on international aircra and in government-run areas by the Japanese Quarantine Station, Ministry of Health, Labour and Welfare between 2008 and 2018. In total, 22,452 aircra were inspected and 822 adult mosquitoes (including 145 dead mosquitoes) were collected from 240 (1.07%). e majority of the mosquitoes on aircra belonged to Culex. e most abundant Culex species was Cx. quinquefasciatus and 469 adults were captured. Among them, 398 were collected from aircra from India. e second-most abundant was Cx. pipiens complex (158 adults) and the third was Cx. gelidus (100 adults). An important invasive dengue vector, Aedes aegypti (2 adults), was captured on an aircra from the Philippines. In mosquito inspection at government-run areas, the invasion of Ae. aegypti was con rmed at Narita International Airport in 2012, 2013, 2014, 2015, and 2017, Tokyo International Airport (Haneda Airport) in 2013, and Chubu Centrair International Airport (NGO) in 2016 and 2017. Virus detection from the collected mosquitoes revealed Japanese encephalitis virus gene (genotype I, a prevalent genotype in Japan at present) from Cx. tritaeniorhynchus captured at Narita International Airport in 2013, Mikawa Port in 2015, and Kyushu Saga International Airport in 2017.

: Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne diseases caused by the SFTS virus (SFTSV). In recent years, with the expansion of wildlife habitat, the chances of ticks invading a human living area have increased, accompanied by an increased risk of SFTSV infection. Here, we investigated the tick fauna and distribution of SFTSV in Fukuoka Prefecture and analyzed the factors associated with the occurrence of SFTS. A total of 1307 ticks were collected by flagging on vegetation between March and November during the study period from May 2017 to August 2019. Using cluster analysis based on the proportion of tick species at the collection points, we roughly classified the tick fauna in the prefecture into three clusters (Clusters 1 ‒ 3). The proportion of Haemaphysalis longicornis was extremely high in Cluster 1, and we detected SFTSV in one of the samples. We identified patients in the area of Cluster 1 ̶ the habitat of deer ̶ the main host of ticks, which was geographically consistent with the area of Cluster 1.
