“…We have focused on blood-stained eggs as a consequence of poultry red mites. In Japan, poultry farm workers sometimes leave their jobs (Murano et al 2008(Murano et al , 2015 because they have been suffering from transient skin irritation, more serious eczema and even allergic reactions (Potenza et al 2008;Sahibi et al 2008;Cafiero et al 2011). In our preliminary study, workers started to complain about the mites when the stained eggs were first observed at both farms (data not shown).…”

The poultry red mite (Dermanyssus gallinae) is a serious problem for the poultry industry worldwide. However, the relationship between the mite population and the damage that they cause is still unclear. In this study, the mite population in poultry houses was examined using an established trap method, and the risk of blood-stained eggs caused by the mites was assessed. Traps were placed once a week outside the egg channels and/or on the floor in two poultry farms in Fukuoka Prefecture, Japan, from April 2012 to July 2014. The numbers of blood-stained eggs and total eggs were counted at weekly intervals. The results showed that the number of mites increased from April to May, and reached a peak around the beginning of June when the average temperature and humidity were >24°C and 70-90%, respectively. In the segmented model, the correlation between the proportion of blood-stained eggs and the number of mites or temperature was positive over a threshold. In conclusion, our established trap method is useful for monitoring mites and can be used to predict when poultry farms should be treated to prevent appearance of blood-stained eggs.

“…The fastest and easiest way to control mites in the henhouse is to use chemical agents. However, resistances against acaricides (Murano et al 2009 ) and the chemical residue after treatment (Marangi et al 2012 ) is viewed critically. Resistances have been reported in many countries and for different groups of active ingredients (Beugnet et al 1997 ; Nordenfors et al 2001 ).…”

Management of the poultry red mite, Dermanyssus gallinae, using silica-based acaricides

et al. 2020

Four silica-based acaricides were examined in laboratory tests for their effectiveness against poultry red mite, Dermanyssus gallinae. All acaricides resulted in 100% mite mortality. Two groups of active ingredients could be differentiated. The products Silicosec® and Ewazid®, based on naturally occurring diatomaceous earth (DE), killed 100% of adult D. gallinae within 48 h exposure time. The time to kill 50% of the mites (LT50) was calculated to be 31.7 and 34.9 h, respectively. The other two products, containing aggregates and agglomerates of pyrogenic synthetic amorphous silicon dioxide as active ingredients, killed the mites in a significantly shorter time: LT50 was 6.3 h for the liquid product Fossil Shield® Instant White and 11.8 h for the powdery product Fossil Shield 90.0 White. This is more remarkable as the quantities of active ingredients used for the DE treatments were several folds higher. The effectiveness of all tested products was also shown in practical tests. A professional company treated five chicken houses on one farm in the Berlin–Brandenburg region with the test products, three houses with Fossil Shield Instant White and one each with Ewazid and Silicosec. Over a period of 46 weeks after stocking, the mite development in the houses was assessed. Only in one of the houses, treated with Fossil Shield Instant White, the mite population remained permanently low. In two houses treated with Fossil Shield Instant White, small mite colonies appeared in week 36, which were controlled by a follow-up spot treatment in week 41. In the houses treated with DE, the first mite colonies appeared 12 weeks after stocking. The number increased continuously over the experimental period and in week 31 after stocking there were clearly visible colonies (2–3 cm diameter) and the first mites could also be detected on the chicken eggs. At this time both houses were treated again with a follow-up spot-treatment, which only led to a slight improvement in one house and to a stabilization of the infestation in the other house. In week 41, large mite colonies were detected in both houses. A spot treatment at this point was ineffective in reducing the infestation. The tests showed faster acaricidal action of the products with the synthetic active ingredients compared to the natural DE-based products. This matches the shorter killing times under laboratory conditions. The experiments in a commercial chicken farm showed that it is possible to control the mite population for a period of 46 weeks by using physically effective SiO2-based products. These products are therefore an effective alternative to the use of chemical acaricides.

“…A variety of chemical medicines such as organo phosphorous compounds (dichlorvos, malathion, metriphonate), carbamates (propoxur), and synthetic pyrethroids (cyfluthrin and pyrethrin I and II) were used in poultry house (Höglund et al, 1995 Murano et al, 2008). However, these reports show that many chemicals were difficult to exterminate red mites perfectly in a short term.…”

Effects of wood vinegar (WV) on red mites, safety test for chicks, and egg production performance were examined. In the counting of red mite numbers at cage knots using RGB color range of red mites by the image analyzer, the red mite were decreased after spraying (P＜0.01). In a WV safety test for 8-day-old chicks, one ml of water, original WV, or WV diluted 500 and 1,000 times were tube-fed twice daily for 6 days. The rate of body weight gain was decreased in original WV group than that in the control (P＜0.05), but it was not different in both WV dilution groups compared with that in the water-only group. In spraying one ml WV to the hen's face twice per day for 8 days, the egg production performances of WV group did not changed so much compared with those of the control and initial day. These results suggest that the WV did not reduced production performance.From these results, WV could exterminate red mites, and did not reduce egg production, suggesting that WV is a useful natural substance to exterminate red mites without harmful effect.
