Cucurbit yellow stunting disorder crinivirus mainly infects plants in the Cucurbitaceae family, including melons, cucumbers and pumpkins. It can also infect other crop species, such as alfalfa, lettuce, beans and weeds. In recent years, it has been observed in many European countries, mainly in the Mediterranean region, as well as in China, North America and the Middle East. The virus is transmitted by the sharp-winged whitefly (Bemisia tabaci) in a semi-permanent manner; however, it is largely introduced into the crop accidentally, along with infected propagating material. Poland is one of the main producers of cucumbers in Europe. In addition, many other plants of the Cucurbitaceae family are also grown. Due to the widespread occurrence of host plants in our country, the virus may pose a potential threat to crops once it enters Poland.
