Study of acaricidal properties of lowtemperature smoke generators containing cyfluthrin against red chicken mite

In order to determine the effectiveness of SMOK® insect low-temperature smoke generators in poultry farming facilities at the egg factory against the red chicken mite (Dermanyssus gallinae), treatment was carried out using a different number of generators in the premises to identify the optimal dose of the active substance to combat the dermanyssus mites.SMOKE® insect generators contain 40 g of cyflutrin, which is the main active ingredient. Four poultry farming facilities were treated, in which the presence of a red chicken mite was previously noted. All rooms had the same volume of 8000 m3. The treatment was carried out using a different number of generators to identify the optimal dose of the active substance in the fight against the parasite.All rooms were previously treated with a mixture of ammonia (25%) and formaldehyde (40%) for the purpose of disinfection.Rooms No. 1, 2 and 3 were treated with low-temperature smoke generators with a dose of the active substance 320, 640 and 960 g per 8000 m3, respectively. Room No. 4 served as a control room, and only ammonia and formaldehyde solutions were treated in it.The effectiveness of deacarization was taken into account 1, 30, 90, 150, 210 and 270 days after the treatments. As a result of the effectiveness assessment in room No. 1 treated with SMOKE® insect smoke generators,where the dose of the active substance was 320 g per 8000 m3, the recovery of the red chicken tick population began 210 days after treatment. In rooms No. 2 (dose 640 g.) and No. 3 (dose 960 g.), a red chicken mite appeared 270 days after deactivation. In room No. 4, where only ammonia and formalin solutions were treated, ectoparasites were detected 30 days later.
