Response of wild mus musculus to baits containing essential oils: II bromadiolone and difenacoum baits with 0.75% cinnamon oil tested in storages

Abstract

The effects of 0.75 % concentration of cinnamon essential oil on bait attractiveness and total biological efficacy of bromadiolone and difenacoum rodenticides to the house mouse were tested in practice. The experiments were conducted in storages with stable house mouse populations for which no resistance to anticoagulant rodenticides had been previously reported. A statistically significant difference was detected between bromadiolone and difenacoum baits. Consumption of bromadiolone baits supplemented with cinnamon essential oil was 74 % higher than the consumption of bromadiolone baits without cinnamon oil. The average efficacy of bromadiolone baits in controlling house mice was 96 %. Cinnamon essential oil added to difenacoum baits increased bait consumption by 39 %, i.e. it was 119 % higher than the consumption of oil-free baits. The average efficacy of difenacoum baits in controlling house mice was 99.5 %.

Utvrđen je uticaj etarskog ulja cimeta, u koncentraciji 0.75 %, na ispoljavanje atraktivnosti mamaca, kao i ukupna biološka efikasnost aktivnih materija bromadiolona i difenakuma za domaćeg miša u praktičnim uslovima primene. Eksperimenti su izvedeni u skladišnim objektima, sa stabilnim populacijama domaćeg miša, za koje nije bila utvrđena rezistentnost na antikoagulantne rodenticide. Utvrđena je statistički značajna razlika između ispitivanih mamaca na bazi bromadiolona i ispitivanih mamaca na bazi difenakuma. Mamci na bazi bromadiolona, sa sadržajem etarskog ulja cimeta, prosečno su bili konzumirani za 74 % više od mamaca na bazi bromadiolona u kojima nije bilo dodatka ulja. Prosečna ukupna efikasnost ovih mamaca u suzbijanju domaćeg miša bila je 96 %. Povećanje konzumacije mamaca na bazi difenakuma sa dodatim eteričnim uljem cimeta u ovom eksperimentu bila je za 39 %, odnosno 119 % viša u odnosu na mamce bez dodatka eteričnog ulja. Prosečna ukupna efikasnost ovih mamaca bila je 99,5 % u suzbijanju domaćeg miša.
