Evaluation of essential coriander (Coriandrum sativum L.) oil against the red poultry mite (Dermanyssus gallinae) (De Geer, 1778) (Acari: Dermanyssidae) under laboratory conditions
The red mite Dermanyssus gallinae affects poultry production mainly of laying hens by feeding on its blood. Its control is carried out using chemical acaricides, toward which its resistance increases. The aim of this study was to evaluate the acaricidal activity of essential oil (eo) of coriander (Coriandrum sativum) at concentrations of 1, 2 and 3 mg/cm2 through contact bioassays on adults of D. gallinae, compared to a chemical acaricide (Neguvón®). The mites were collected from backyard hens (Gallus gallus L.). Six replicates were performed per treatment. Statistically, mortality percentages were established and an anova was carried out. The lethal activity percentage was established. Additionally, the median lethal concentration (LC50) and the median lethal time (TL50) were estimated. Coriander eo caused 100 % mortality on D. gallinae population 25 min after contact with a concentration of 2 and 3 mg/cm2 and after 30 min with a lower concentration of 1 mg/cm2. The LC50 of the coriander eo was 1.3 mg/cm2, with a 13 min TL50 on the D. gallinae population. The eo of coriander is suggested as an alternative to be used instead of the chemical acaricides for the control of the red poultry mite D. gallinae.
