The study investigates the comparative toxicity of three widely used insecticides-fenitrothion, malathion, and deltamethrin-on , a major urban pest. Using bioassay tests based on World Health Organization (WHO) protocols, we determined the lethal doses 50 (LD) for each insecticide. 2.

Article Synopsis
  • - This study is the first comprehensive phylogenetic analysis of the Anopheles hyrcanus group in northeastern Iran, which is known for transmitting diseases like malaria and Japanese encephalitis, comparing findings with data from other regions in Iran and globally.
  • - Researchers collected 819 adult mosquitoes from various locations in Golestan province between April and December 2023, using taxonomic keys for identification and performing DNA analysis with PCR sequencing techniques.
  • - Results showed that An. hyrcanus was the second most common species in the area, with phylogenetic analyses confirming its monophyletic lineage and revealing 11 distinct haplotypes, while the COI gene had low diversity and the ITS2 gene was divided into two clades related

Coronavirus is one of the main pathogens that primarily targets the human respiratory system. There are several ways to transmit this virus, such as direct contact or droplets spread by coughing or sneezing, and direct contact with fomites and surfaces is another way. This cross-sectional study was conducted in Shiraz, southern Iran, in 2021.

Article Synopsis
  • This study investigates the feeding behaviors of the sand fly Phlebotomus sergenti in Bam County, Iran, which is linked to a case of Anthroponotic Cutaneous Leishmaniasis.
  • Two methods were employed: capturing blood-fed sand flies to identify their blood sources using Multiplex PCR and baiting traps with various animals to observe feeding preferences.
  • Results showed a preference for canine and poultry blood, with the majority of sand flies attracted to chickens, highlighting the role of dogs as primary hosts for this sand fly species.

Mosquitoes are involved in the transmission of a wide range of diseases and among them, , acts as a vector of avian malaria, tularemia and several arboviruses like West Nile fever. The current study was conducted to determine the susceptibility of against deltamethrin 0.05% (pyrethroids), fenitrothion 1.

Spiders are the largest order of arachnids with some medically important species. Considering that no comprehensive research has been conducted on the fauna and distribution of Araneae in Bashagard County (Hormozgan Province) so far, the present investigation has been carried out on these essential issues in this deprived tropical region. Fifteen sampling locations were selected based on the extent of each area and considering climatic characteristics.

Background: In Iran, the prospect of malaria control relies mainly on insecticides used against the genus (Diptera: Culicidae) as important vectors of malaria, arboviruses, and so on. Only eight out of 30 malaria mosquito vectors ( species) have been examined for insecticide resistance in Iran. This study aimed to review articles related to the incremental trend in insecticide resistance and their mechanisms among anopheline malaria vectors in Iran.

This is the first report of SARS-CoV-2 detection on field-collected Musca domestica housefly surface and tissue samples using the high-sensitive PCR assay which suggests the possible insect-borne transmission. The study was conducted in Shiraz city, southern Iran, in May and Jun 2020. Adult flies were sampled at the outdoor areas of two hospitals treating COVID-19 patients.

Objective: Among the mosquitoes, plays a notable role in the transmission of avian malaria, tularemia and arboviral diseases, including West Nile fever. We conducted this study to characterise the cytochrome oxidase I (COI) and internal transcribed spacer 2 (ITS2) fragments of in northwestern Iran to determine the classification status of this species.

Methods: The COI and ITS2 fragments from six populations of were amplified, sequenced and analysed.

Objective: Delusional parasitosis (DP) is one type of psychotic disorders. It is a multifactorial disorder with different etiologies. Given that very little attention is paid to entomological survey in these cases, a comprehensive study was designed and performed for the first time in Iran on a suspected DP case and its home from Shiraz during 2018-2019.

Objective: The potential use of symbiotic bacteria for the control of mosquito-borne diseases has attracted the attention of scientists over the past few years. Culiseta longiareolata is among the medically important mosquitoes that transmit a wide range of vector-borne diseases worldwide. However, no extensive studies have been done on the identification of its symbiotic bacteria.
