Acaricidal activity of active substances of essential oils against poultry red mites (Dermanyssus gallinae)

Popis výsledku v původním jazyce

The main objective of this study was to monitor mortality of poultry red mites (Dermanyssus gallinae, PRM), caused by selected active substances of plant essential oils (eugenol, linalool, cinnamaldehyde, limonene, eucalyptol, menthol). The second objective was to define the lethal doses (LD50; LD90) of these active substances. The acaricidal activity of these active substances against poultry house-collected red mites was examined 24 hours after treatment using direct contact method - by glass vial bioassay. The tested concentrations of active substances of essential oils were from 1 to 0.0005 μL/cm2. Active substances of essentials oils were dissolved in water and Tween 20. Only adult PRM were used for the tests. The average mortality in the negative control was 2.5%. All used active substances caused mortality of PRM. The highest estimated mortality was observed with eugenol (85%), the LD50 was estimated to be 4.3 μg/cm2 for this substance, followed by cinnamaldehyde (79%), the LD50 of which was estimated to be 11.6 μg/cm2 and menthol (74%), the LD50 was estimated to be 17.8 μg/cm2. Linalool, limonene and eucalyptol were generally less effective. The results of these performed experiments suggest that active substances like eugenol and cinnamaldehyde and menthol in merit further study as potential PRM control agents. Active substances of essential oils may be effective natural botanical pesticides against PRM.
