Harm Dilling, owner of the tire dealer Dikabo from Assen, is celebrating an anniversary: The Asian tiger mosquito has been found there for the tenth year in a row. Dilling does not know exactly how much. “I will only find out at the end of the year from the Danish Veterinary and Food Administration (NVWA).
Asian tiger mosquitoes can transmit more than twenty viral diseases such as dengue fever, Zika, chikungunya, West Nile virus and various types of brain infections. The small, striped mosquitoes are not native to the Netherlands.
Dilling goes to the back of the large space on Europaweg, where 80,000 new and old tires are stored. He shows the safety net where the tiger mosquito was probably found. “I have two of those traps on site. Once every two weeks, they are emptied by NVWA and taken to the lab, where they are examined under a microscope for a tiger mosquito.” On June 15 and 27, it was hit.
Wilfred Reinhold, chairman of the platform ‘Stop invasive exotics’, wants to prevent the tiger mosquito from multiplying and states that the tire company is not doing enough to prevent this: “The import of used tires is one of the most important routes through which “Tiger mosquitoes enter the country. Importers are therefore obliged to import the tires dry and store them dry. If the companies comply with the rules, one would never find tiger mosquitoes, because the eggs in the tires must have water to hatch.”
Owner Dilling would like to get rid of the image that his company is not doing enough to keep the tiger mosquito away. “Tires coming from high-risk areas, such as Italy, are delivered dry, unloaded and stored dry. All those tires get a sticker stating that they come from a high-risk area. I follow the rules and NVWA often comes here to check. “
This is confirmed by NVWA: “As soon as an exotic mosquito is found on a tire company, we start the fight with the help of a control company. This means fighting adults with a biocide as well as against larvae in the tire company. The environment is checked for potential breeding sites, such as buckets , hills, water jugs, a rain barrel with rainwater, and an inspection is carried out to determine the situation on the farm and whether they comply with the rules A tire company is found does not automatically lead to a fine to the tire company. tire company does not comply with the rules, “said a spokesman for NVWA.
Dilling is therefore annoyed that the platform ‘Stop invasive exotics’ sees the tire trade as the source of the tiger mosquito problem. “The tiger mosquito is not only found in the tire shop, but also in Aalsmeer at the flower auction, at Schiphol and in residential areas. In addition, holidaymakers take the mosquito unnoticed when, for example, they camp by an Italian lake. Asian tiger mosquitoes fly with everything.”
That picture is confirmed by NVWA: “Tiger mosquitoes most likely come along with travelers and / or freighters who have visited Southern Europe or other continents. In large parts of Southern Europe, the Asian tiger mosquito is common and there are established populations.”
In addition, NVWA has announced that the number of mosquitoes found at tire companies has decreased over the past ten years.
In addition to dry storage of the tires, the owner of the Asser tire store has another solution to defeat the tiger mosquito: “I want to disinfect every load from a risk area. But according to Dutch rules it is not allowed. These rules prescribe that all tires must be disinfected “That means that instead of 300, more than 80,000 tires have to be made. And also by a separate company; I can not do that myself.”
Deck Director Dilling will not be celebrating the bitter anniversary of the visit of the tiger mosquito ten years in a row. “We have a party from someone who’s been employed for 25 years. It’s fun, at least.”
