An infestation of a Cimicidae (Hemiptera: Cimicidae) member, especially the bed bug, can cause economic loss and impact health. A cost-effective and user-friendly method for identifying the infesting species will help with the early detection and control of infestations. A linear morphometric method is often used, but it requires the examination of many characters and a highly preserved specimen.

Accurate identification of mosquito species is critically important for monitoring and controlling the impact of human diseases they transmit. Here, we investigate four mosquito species: , , and that co-occur in tropical and subtropical regions, and whose morphological similarity challenges their accurate identification, a crucial requirement in entomological surveillance programs. Previous publications reveal a clear taxonomic signal embedded in wing cell landmark configuration, as well as in the external contour of the wings.

Arthropod-borne viral diseases (arboviruses) are a public-health concern in many regions of the world, including Thailand. This review describes the potential vectors and important human and/or veterinary arboviruses in Thailand. The medically important arboviruses affect humans, while veterinary arboviruses affect livestock and the economy.

Background: Controlling sites where mosquitos breed is a key strategy in breaking the cycle of infectious transmission of the dengue virus. Preventive behaviors, such as covering water containers with lids and adding temephos (commercially named Abate sand) in water containers are needed to reduce and control mosquito breeding sites. This study aimed to investigate the impact of dengue-preventive behaviors on Aedes immature production.

Article Synopsis
  • Specific IgE testing for the imported fire ant (Solenopsis invicta) is commonly used to diagnose ant allergies, but Thai patients may experience anaphylaxis from other ant species.
  • In a study of 32 patients with ant anaphylaxis, S. geminata (tropical fire ant) was identified as the most frequent cause, accounting for 37.5% of cases.
  • Analysis revealed 13 protein components in S. geminata that bind to IgE, with three major allergens identified, supporting the role of IgE in anaphylactic reactions among patients.

Bat bugs are blood-feeding insects of bats or warm blooded animals and humans. Since 2011, Leptocimex spp (Heteroptera: Cimicidae) has been reported in Thailand. However, microscopic examination of Leptocimex spp is complicated, especially when the entire body of the specimen is not available.

The chikungunya virus (CHIKV) is a mosquito-borne virus that has recently re-emerged in several countries. On infection, the first vertebrate cells to come into contact with CHIKV are skin cells; mosquitoes inoculate the virus together with salivary gland protein into host skin while probing and feeding on blood. However, there is little known about the susceptibility of human skin cells to CHIKV infection.

Aedes albopictus C6/36 cell line was used to evaluate dengue virus serotype-3 (DENV-3) and chikungunya virus (CHIKV) co-infection. Virus infection was determined using a one-step duplex reverse transcriptase polymerase chain reaction (D- RT-PCR). D-RT-PCR was positive for both viruses when equal multiplicity of infection (MOI) was utilized.
