Socioeconomical Factors Associated With Pediculosis (Phthiraptera: Pediculidae) in Athens, Greece
Pediculosis in humans and especially in children is a very common dermatological disorder caused by the ectoparasite Pediculus humanus capitis De Geer. We investigated the socioeconomic factors affecting the prevalence of pediculosis in the Greek urban area of Athens during 2004-2006. The target population consisted of children from kindergartens.

Knockdown Resistance Allele Frequencies in North American Head Louse (Anoplura: Pediculidae) Populations [PDF]
The study examines the extent and frequency of a knockdown-type resistance allele (kdr type) in North American populations of human head lice. Lice were collected from 32 locations in Canada and the United States. DNA was extracted from individual lice and used to determine their zygosity using the serial invasive signal amplification technique to ...

Cytogenetic Features of Human Head and Body Lice (Phthiraptera: Pediculidae)
The genus Pediculus L. that parasitize humans comprise two subspecies: the head lice Pediculus humanus capitis De Geer and the body lice Pediculus humanus humanus De Geer. Despite the 200 yr of the first description of these two species, there is still a long debate about their taxonomic status.

Abstract Knockdown resistance (kdr) is a common mechanism of insecticide resistance in head lice to the conventionally used pyrethroid pediculosis and can be the result of various amino acid substitutions within the voltage-sensitive sodium channel (VSSC).

High diversity and rapid diversification in the head louse, Pediculus humanus (Pediculidae: Phthiraptera). [PDF]
AbstractThe study analyzes sequence variation of two mitochondrial genes (COI, cytb) inPediculus humanusfrom three countries (Egypt, Pakistan, South Africa) that have received little prior attention and integrates these results with prior data. Analysis indicates a maximum K2P distance of 10.3% among 960 COI sequences and 13.8% among 479 cytb sequences.

In Vivo and In Vitro Rearing ofPediculus humanus capitis(Anoplura: Pediculidae) [PDF]
Four geographically distinct colonies of the human head louse, Pediculus humanus capitis De Geer (Anoplura: Pediculidae) were reared on a live host and exhibited significantly different life history patterns. Florida head lice exhibited approximately 10% slower development and approximately 15% reduced longevity relative to California or Ecuador head ...

Insecticidal Activity of Plant Essential Oils AgainstPediculus humanus capitis(Anoplura: Pediculidae) [PDF]
The insecticidal activity of 54 plant essential oils against female Pediculus humanus capitis De Geer was examined using direct contact and fumigation methods, and compared with the lethal activity of delta-phenothrin and pyrethrum, two commonly used pediculicides. In a filter paper contact bioassay with female P.

Ovicidal Efficacy of Abametapir Against Eggs of Human Head and Body Lice (Anoplura: Pediculidae). [PDF]
Studies were undertaken to determine the ovicidal efficacy of 5,5'-dimethyl-2,2'-bipyridyl (abametapir) against eggs of both human head and body lice. Head lice eggs of different ages (0-2, 3-5, and 6-8-d-old eggs) were exposed to varying concentrations of abametapir in isopropanol and concentration-dependent response relationships established based on
