Abstract
The Norway rat and house mouse the most important rodent pest at farms eat and polullut the huge food quantity and carry a range of severe infectious deseases to humans and pets. Rodent control is undertaken only after its presence has been registered. Preparations for their control need to meet palatability requirements. Experiments were conducted in animal food blender facilities and pig farm (maternity and rooms with young and adult pigs) in Omoljica following the standard EPPO method. Palatability and efficacy of RB formulated baits (paste in special 10 g paper bags) containing 0.005% bromadiolone and 0.005% brodifacoum were tested against the house mouse and Norway rat . Baits in pelllete formulation were used as the standard. All the baits were placed in special boxes. Rodent abundance was evaluated based on the highest and the lowest daily baits consumption divided by the daily required of food amount, and a census method before and after treatment. Rodent presence was monitored over the next 20 days. The efficacy of the tested RB soft bag and standard formulations was calculated according to Abbott's formula. The results showed that palatability and efficacy of RB soft bag formulations (81-100%) was substantially high especially of brodifacoum-based baits.
Highlights
House mouse (Mus musculus) is one of the commonest rodent species
The results showed high palatability of all the tested RB soft bait formulated preparations for house mouse (Mus musculus) and Norway-grey rat (Rattus norvegicus) compared with the referent pellet formulated preparation
Our results showed high values (80,.00 do 97,50%) of all the tested RB soft bait preparations for the Norway-grey rat (Rattus norvegicus) control and very high efficacy (91,60 do 100 %) for the house mouse (Mus musculus) control
Summary
House mouse (Mus musculus) is one of the commonest rodent species. Rodents have important epidemic significance as natural source and main vector of pathogens of animal and human origin or indirectly by numerous ectoparasites (Gratz, 1988; Morita, 1995; Stajković at al., 1995; Leirs, at al., 2004; Olumide, 2008; Kyriakis and Alexopulos, 2011). In our country it is recorded several cases of trichinelosis and hemorragic fever wich were quite often ended with death. At the one farm died 30, while at the other died 60 tons of rats wich were colllected, mixed with the oil and burned (Radosavljević, 2003)
