Abstract
- Introduction: International trade of tires has been responsible for the introduction of invasive Aedes species into many countries. The present study aimed to determine the sources and volume of such trading in Iran and to establish and map points of entry for entomological surveillance.<br />Method: A list of tire importers, type and number of tires and source of their shipment was compiled, and the map of the main location(s) of their depot in the country was produced from 2017 to 2018. Contamination of imported tires with mosquito eggs or larvae was also determined. The samples from all parts of the warehouse were taken randomly from 4 to 20 tires every 15 days. In tires with a trace of water inside, the existence of the egg and larva of Aedes mosquitoes was investigated by sticking the glue band to the hot spot of left water inside the unpacked tires.<br />Results: Approximately one-third of the annual tire requirements of Iran were imported from 15 countries, most of which were endemic to Aedes aegypti and or Ae. albopictus. It is obligatory to import only wrapped tires. About 10% of total country consumption is imported through informal markets and smuggled. However, the unofficially imported tires are usually not wrapped. The majority of tire imports were made through the southern ports of the country. The main sites for depots of imported tires were located in four Iranian provinces, namely Tehran, Isfahan, Fars, and Sistan and Baluchestan. The latter is extremely important given its border with Pakistan. Depot locations were mostly unstructured, and tires were kept in the open air. All these depot locations were at the edge of towns and residential areas. Priority areas for routine entomological surveillance were established. Such as the previous studies, surveillance of imported tires for the presence of Aedes eggs or larvae was negative in this study.<br />Discussion: Mapping the entry points of imported tires and their origin is crucial to determine and prioritize sites for entomological surveillance of invasive mosquito species. Strengthening collaboration with customs authorities and the association of tire importers is imperative in this effort. The development of national rules and regulations for tire import is necessary to minimize the danger of the introduction of invasive vector species into the country.<br /> (Copyright © 2022 Elsevier Ltd.
