Meteorological experts in Egypt have warned citizens about the invasion of desert flies, currently entering the country alongside the Khamsin winds, having reached Matrouh Governorate. Experts have advised people to close their windows to protect their health and safety from the harms of these flies, which come as a result of the southern desert winds from Sudan.
Egypt is particularly vulnerable to desert fly invasions due to its geographic location and climate. During spring, the Khamsin winds carry desert sands and aid in the spread of desert flies from their original habitat in the desert to populated areas.
The Rise in Temperature
Experts believe that the spread of desert flies across various regions, especially in villages and centers in Upper Egypt, is linked to rising temperatures. They explain that the appearance of snakes, scorpions, and various insects including desert flies is a natural phenomenon expected at this time every year due to the onset of a new climatic season and increased temperatures.
According to Wikipedia, some important information about desert flies includes that they measure no more than a quarter of a centimeter and come in various colors such as blue, brown, and black. They feed on garbage and other types of waste, with some species consuming anything decaying, such as agricultural waste. The name "desert fly" originates from their migration from Sudan towards the desert, and they are resistant to harsh winds that would typically kill other insects; their numbers typically increase with the start of the season.
What Are Their Harms?
Desert flies cause significant discomfort to both humans and animals through painful bites and severe itching. They can also transmit diseases such as anthrax and viral encephalitis. Furthermore, they negatively impact livestock production by reducing the amount of milk produced by cows and pose a threat to food security due to their potential to damage crops.
How Can They Be Controlled?
Experts suggest that desert flies can be managed by removing breeding sources like garbage and organic waste, using fly traps, and spraying insecticides in infested areas. Additionally, some advise the use of incense to repel them from homes.
Earlier yesterday, the Egyptian Meteorological Authority issued a strong warning regarding the activity of the Khamsin winds starting today in many areas across Egypt, particularly Greater Cairo. Dr. Mahmoud Al-Qiati, a member of the media center at the Meteorological Authority, stated that Khamsin winds occur in spring and are named for lasting 50 days, although this does not mean they are continuous; they can occur intermittently from March to June.
