Abstract. The housefly Musca domestica causes great harm to agriculture. These insects carry many pathogens that are dangerous to animals and humans. It is known that this species has developed a high resistance to many chemicals. The most suitable breeding grounds for houseflies are the warm and moist surface of decomposing waste in poultry farms, cowsheds and waste processing plants, where these insects lay eggs, which then serve as food for developing larvae. Due to the high fertility and resulting density of winged imagos, they cause irritation and anxiety in animals, and thus, there is a decrease in egg and milk production on poultry and dairy farms. Currently, it is proposed to use plant active compounds as a safer alternative for the environment and in the fight against insect resistance. One of these substances is monoterpene – linalool. Therefore, the purpose of these studies was to evaluate the effectiveness of this compound and compare its activity with chemical insecticides from different classes: fipronil, ivermectin, acetamiprid and chlorfenapyr against larvae of Musca domestica L. laboratory population sensitive to insecticides by the method of introducing active substances into the substrate. As a result of the research, it was revealed that the effectiveness of linalool against housefly larvae was 100% when exposed to them in a 28% concentration. At the same time, the estimated DC50 for this compound was 17.9761 (13.2825-222.7085), and compared with chemicals, it was found to be lower: chlorfenapyr by 8.3 times, fipronil by 215.7 times, ivermectin by 302.1 times, and acetamipride by 21.40 times. The high environmental friendliness of plant compounds attracts researchers to use them against harmful insects. According to the literature, success has been achieved in increasing their effectiveness by modifying the molecule, combining it with other biological substances, etc., which shows the promise of their use.
