“…No conclusions, however, could be drawn with regards to the temporal distribution of the different mite life-stages. This is an important restriction since D. gallinae populations are known to fluctuate widely in poultry houses (Harrison, 1962), and appropriate control measures rely on a solid understanding of the demographic processes.In this paper, we present a mathematical model which contributes to the explanation of population fluctuations and is used as a basis for optimising pest control strategies (Baumg~rtner and Gutierrez, 1989). …”

A model based on a time-varying distributed delay with attrition was developed for simulating the population dynamics of the chicken mite Dermanyssus gallinae (DeGeer, 1778). The model was parametrised according to cohort life table studies conducted under constant temperature conditions and was validated with two independent data set obtained in an experimental poultry house. The predicted mite densities and the stage-structure of the population corresponded to the values observed during experimental periods of 32, and 11 weeks, respectively. Temperature and a poultry house-specific density effect were determined to control the population development.

“…A number of previous studies conducted in laboratory conditions or on layer farms have attempted to do this with varying degrees of success [11–16]. Initially, Harrison [15] suggested that light was one of the key factors influencing activity of D. gallinae . Kirkwood [13] further reported that more mites fed in darkness than in light.…”

Background The poultry red mite (PRM), Dermanyssus gallinae , is one of the most economically deleterious ectoparasites affecting egg-laying hens worldwide. It may be possible to control D. gallinae populations by manipulating lighting regimes within poultry units. However, no studies have clearly shown the effects of darkness on the population growth rate of D. gallinae . Methods The effect of darkness on the population growth rate of D. gallinae was investigated, together with the first description of the molecular identity of the mite from China. Mite variables under two lighting regimens (1:23 h L:D and 12:12 h L:D) were compared, including number of mites and eggs, survival and feeding rates, engorgement, oviposition, hatchability and the life-cycle of D. gallinae. Results The results showed that the number of mites (13,763 ± 956) and eggs (5424 ± 317) in the rearing system with prolonged darkness of 1:23 h L:D at 4th week were 2.4- and 3.6-fold higher than those under a conventional lighting regimen of 12:12 h L:D, respectively. The feeding rates of mites under prolonged darkness ranged from 36.7 ± 1.1% to 52.0 ± 7.0%, which were significantly higher than those under conventional lighting regimen (ranging from 22.6 ± 1.9% to 37.3 ± 1.6%). The mean weight of engorged females (0.26 ± 0.01 mg) and the mean number of eggs per female (on average 5.87 ± 0.36) under prolonged darkness were significantly higher than those under conventional lighting regimen (0.22 ± 0.01 mg and 3.62 ± 0.31, respectively). However, the survival rate ranging from 98.07 ± 0.10% to 98.93 ± 0.19%, hatchability of 97.93 ± 0.01% and the life-cycle of D. gallinae (9 days) was not affected by the lighting period. Conclusions Our findings demonstrated that prolonged darkness significantly promoted the proliferation levels of D. gallinae , resulting in increased number of mites and eggs in the rearing system. The promoted population growth of D. gallinae was found to be related to the increased feeding rate, engorgement level and oviposition level of mites under prolonged darkness. The egg hatchability, the survival rates and the duration of life-cycle of D. gallinae were not affected by the light regimes.

“…Under natural conditions infestations reach a peak in the summer and the mites become inactive in the winter (HARgISON, 1963). HARRISON (1963) suggested that light and temperature are the factors which influence changes of activity and part of the work to be described is an attempt to confirm this. In contrast, Liponyssus sylviarum (Canestrini), the northern fowl mite, usually remains on the host and can feed at any time of day or night (WooD, 1920).…”

Some Observations on the Feeding Habits of the Poultry Mites Dermanyssus Gallinae and Liponyssus Sylviarum

Dermanyssus gallinae kept at 25° remain active throughout the year; the mites tend to feed in the dark but they do not appear to be subject to a photoperiodic influence. Liponyssus sylviarum tend to infest mature contour feathers and it is probably for this reason that female and young chickens are rarely infested. ZUSAMMENFASSUNG EINIGE BEOBACHTUNGEN ÜBER DIE FRASSGEWOHNHEITEN DER HÜHNERMILBEN DERMANYSSUS GALLINAE UND LIPONYSSUS SYLVIARUM Befall mit Dermanyssus gallinae tritt hauptsächlich im Sommer durch normalerweise nachts saugende Milben auf. An einzelnen Vögeln bei einer Temperatur von 25° gehaltene Milben blieben jedoch das ganze Jahr über aktiv. Es wurde beobachtet, daß in der Dunkelheit mehr Milben Nahrung aufnahmen als im Hellen und daß unter den erwähnten Bedingungen nachts mchr als am Tage gefressen wurde. Es wurde kein Unterschied in der Anzahl der saugenden Milben festgestellt, die Dauerbelichtung (74,7%), und denen, die dauernder Dunkelheit ausgesetzt waren (74,0%). Diese Beobachtungen weisen darauf hin, daß D. galiinae keine Nahrungsaufnahmerhythmik besitzt, die photoperiodischen Einflüssen unterliegt, und daß die Temperatur der Hauptfaktor ist, der ihre Aktivität beherrscht. Liponyssus sylviarum, welcher das ganze Jahr über an Vögeln auftritt, befällt selten Jungvögel oder Weibchen. Versuche bestätigten dies und es wurde geschlossen, daß an Vögeln, die jünger als 9 Wochen alt sind, wahrscheinlich keine großen Milbenzahlen auftreten. Es wird vermutet, daß der Grund hierfür darin liegt, daß weder Weibchen noch Jungvögel ausgereifte Konturfedern aufweisen, an denen sich L. sylviarum zu häufen pflegt.
