Acaricide Residues in Laying Hens Naturally Infested by Red Mite Dermanyssus gallinae
In the poultry industry, control of the red mite D. gallinae primarily relies worldwide on acaricides registered for use in agriculture or for livestock, and those most widely used are carbamates, followed by amidines, pyrethroids and organophosphates. Due to the repeated use of acaricides--sometimes in high concentrations--to control infestation, red mites may become resistant, and acaricides ...
متن کاملEfficacy of Phoxim 50 % E.C. (ByeMite) for treatment of Dermanyssus gallinae in laying hens under field conditions
A GCP-controlled, randomised and blind trial used 2 layer houses naturally infested with D. gallinae. One house with space for 23,000 hens was treated with an aqueous solution (2,000 ppm Phoxim, 25 ml/hen place) twice 7 days apart. The second house with space for 21,000 hens was not treated. For quantitative assessment of mite population, 20 cardboard traps per house were deployed onto the cage...
متن کاملImmunological effects and productivity variation of red mite (Dermanyssus gallinae) on laying hens- implications for egg production and quality
Red mite (Dermanyssus gallinae; De Geer, 1778) is currently one of the most detrimental ectoparasites in laying birds across several countries. Symptoms of D. gallinae infestation include reduction in production, poor egg quality, increased mortality and also a compromise to welfare. Feeding on its host for only short periods of time, the red mite spends the vast proportion of its short life-cy...
متن کاملEvaluation of a sampling trap for Dermanyssus gallinae (Acari: Dermanyssidae).
Traps made by rectangular pieces of 3 mm thick corrugated cardboard of four different sizes, 200 by 140 (A), 140 by 100 (B), 100 by 70 (C), and 200 by 40 mm (D), were evaluated as a sampling device for the chicken mite, Dermanyssus gallinae (De Geer). Mites were trapped during 2, 4, 6, 8, and 10 d, respectively, in a poultry house heavily infested with the parasite. Significantly greater number...
متن کاملInvasion of Red Mite (Dermanyssus gallinae) As a Cause of Foot Self-Mutilation in a Laying
