ANALYSIS OF THE EFFECT OF BAITS WITH DIFFERENT CONTENT OF BROMADIOLONE AS AN ACTIVE SUBSTANCE IN RELATION TO HOUSE MICE

Abstract

House mice pose a danger to people`s health and cause significant damage
to their activity. Currently, deratization remains a particularly significant problem, since their
populations have a unique genetic ability to rapidly increase in number and high levels of migration. The study of the effect of baits, which contain different amounts of bromadiolone as
an active substance in relation to house mice is of particular practical importance, aimed at
reducing the pesticide load on the ecosystem and environmental ecology, as well as the analysis of the minimum and maximum doses that cause the death of individuals. House mice are
quite resistant to the effects of rodenticide baits based on the 2nd generation bromadiolone
anticoagulant. Experimental studies showed that the consumption of bait, which contained a
standard concentration of bromadiolone as an active substance (0,005%) for one day in conditions with alternative feeding did not cause 100 % effectiveness. 100 % of death was achieved
only with two days of consumption of grain containing 0,0025 % concentration of active substance. From the obtained data it follows that bromadiolone acts effectively even in lower
concentrations, but, most importantly, it provides good palatability of the bait, which directly
affects the intake of active substance into the body. When analyzing the obtained results of
treated grain feeding, it was found that for the death of a house mouse, the maximum dose
was 26,32 mg/kg, and the minimum was 0,66 mg/kg. The biological activity of the three studied concentrations of bromadiolone as an active substance contributed to good results and fitted into the time frame with a slight increase as the concentration of active substance in the
bait decreased.
