Ecto-parasltes. Eggs of the louse, Menacanthus sp., and adult fowl mites, Ornithonyssus sylviarum were collected from adult birds and nests, respectively. This choice of ecto-parasite species was based on their potential for negative impact on nestling growth and survivorship (Moss and Camin, 1971 Powlesland, 1976). Logistical constraints determined which instar of each ecto-parasite was used. 

Eggs of the louse were found attached to the base of feathers on the heads and necks of adult birds (Boyd, 1951). These eggs were removed and placed in covered, humidified petrl dishes. Adult fowl mites were collected from infested nest boxes by placing a strip of paper amidst a swarm of mites, allowing the mites to board the paper, then depositing the mites and paper into a vial. Upon return to the laboratory, the mites were transferred to covered, humidified petri dishes. 

The northern fowl mite, Ornithonyssus sylviarum (Arcari Macronyssidae), is an obligatory blood-feeding ectoparasite (hematophagous mite), which is considered to be one of the most important and common pests of poultry. This mite is sensitive to lambda-cyhalothrin, cypermethrin, fenvalerate, and permethrin. Due to short residue time, many registered compounds often need to be repeated after 2-4 weeks. Residue time of an insecticide on feather depends not only on the nature of but also on the formulation of the drug [39]. 

Poultry cages have been treated in either of two ways to control fowl mites at an almost 100% success rate. One method involved the hanging of pesticide-impregnated strips in the cages and the other method involved circulating the insecticide through plastic tubes.
