Validation of an automated mite counter for Dermanyssus gallinae in experimental laying hen cages.

Mul MF, van Riel JW, Meerburg BG, Dicke M, George DR, Groot Koerkamp PW - Exp. Appl. Acarol. (2015)

Bottom Line: This validation study resulted in 17 data points of 'number of mites counted' by the automated mite counter and the 'number of mites present' in the experimental laying hen cages.The study demonstrated that the automated mite counter was able to track the D. gallinae population effectively.A wider evaluation showed that this automated mite counter can become a useful tool in IPM of D. gallinae in laying hen facilities.

ABSTRACT
For integrated pest management (IPM) programs to be maximally effective, monitoring of the growth and decline of the pest populations is essential. Here, we present the validation results of a new automated monitoring device for the poultry red mite (Dermanyssus gallinae), a serious pest in laying hen facilities world-wide. This monitoring device (called an "automated mite counter") was validated in experimental laying hen cages with live birds and a growing population of D. gallinae. This validation study resulted in 17 data points of 'number of mites counted' by the automated mite counter and the 'number of mites present' in the experimental laying hen cages. The study demonstrated that the automated mite counter was able to track the D. gallinae population effectively. A wider evaluation showed that this automated mite counter can become a useful tool in IPM of D. gallinae in laying hen facilities.

Fig3: Measured data points for cage 1–9 and modelled relationship (line) for the number of mites present in the cages versus the number of mites counted (both ln transformed)

Mentions: The 17 data points and the modelled regression line obtained from the analysis are shown in Fig. 3. The Goodness of fit (R-square) of this line was 90.3 %, supporting that about 90 % of the variation in ‘# of mites counted’ was explained by the level of the reference value (‘# of mites present’). The value for 95 %-CIr was 1.17, meaning that 95 % of the individual measurements were in the relative range of (−117 %; +117 %).Fig. 3
