How To Prevent Red Mites Infestation In Poultry?
Dermanyssusgallinae (the common red mite) are bloody sucking ectoparasites that infest the poultry sector especially chickens and turkeys. They are generally white or greyish in colour, becoming darker or redder when engorged with blood. After feeding, they hide in cracks and crevices away from daylight, where they mate and lay eggs.
Life Cycle: The life cycle from egg to adult mite is only seven days, and they progresses through 5 life stages: egg, larva, protonymph, deutonymph and adult. Under favourable conditions this life cycle can be completed within seven days. They start off as very small greyish-white mites that swell up into red coloured mites after a feed and at their biggest are only 0.7 mm so small numbers of them can be hard to spot unless you know what to look for.
Hazardous Effects: They affect the health of the birds indirectly by serving as vectors for various diseases such as Salmonellosis, etc.Low numbers of mites mainly cause irritation and annoyance to the chicken making it restless. However, large numbers of mites can suck enough blood causing anaemia in the chicken, resulting in a pale comb and wattles, weakness, dullness and reduced egg production.
Consequences Of Red Mite Infestation: Restlessness and stress in the flock; Skin irritation, reduced plumage quality, dermatitis; Feather-pecking, cannibalism Weight loss, anaemia; Negative impact on...
