The preparation of preserved preparations is one the useful methods to determine morphology ectoparasites and insects whose manufacturing process goes through four stages starting with 10% KOH fixation, dehydration process, clearing mounting process. immersion serves thin out chitin layer that forms exoskeleton, which a thick covering on body surface Pediculus humanus capitis (human lice). purp...

The head louse, Pediculus capitis De Geer (Phthiraptera: Pediculidae) has developed resistance to organochlorines, the organophosphate malathion and to pyrethroids in the U.K. Therefore, headlice from Bristol school children were bioassayed against two new insecticides, fipronil and imidacloprid. Pediculus capitis was fully susceptible to imidacloprid, but it required a relatively high dose and...

Blood-sucking lice of humans have extensively fragmented mitochondrial (mt) genomes. Human head louse and body louse have their 37 mt genes on 20 minichromosomes. In human pubic louse, the 34 mt genes known are on 14 minichromosomes. To understand the process of mt genome fragmentation in the blood-sucking lice of mammals, we sequenced the mt genomes of the domestic pig louse, Haematopinus suis...

In reviewing the current extent and epidemiology of louse infestations in human populations and between host and another, it is accepted that is infested by two species of lice/ of which consists of two subspecies (Busvine, 1976). The two species Pthirus pubis, the crab louse, andiPediculus humanus, the human louse, the latter with its two subspecies, P. h. capitis, the head louse, and P. h. hu...
