A one-year study of the biting and resting habits of the malaria vector Anopheles albimanus was carried out in four rural villages of northern Haiti. Man-biting rates and nightly biting cycles were determined by the use of all-night man-biting captures inside and outside houses. Seasonal changes in density and behavior were determined by repeating the captures on a bimonthly basis throughout on...

Tongue biting, traditionally believed to be a specific clinical sign favoring epilepsy, is also reported to occur in syncope and psychogenic seizures(2). Lateral tongue biting (on the sides) is more specific for a diagnosis of true epilepsy as compared to syncope(2) or psychogenic seizures, where biting of the lip or tip of the tongue is seen(3). Nocturnal tongue biting (NTB) can rarely be the ...

We investigated the functional morphology and ecology of biting among the squamipinnes, an assemblage of nine successful and distinctive reef fish families. We demonstrate that an intramandibular joint (IMJ) may have evolved at least three and possibly five times in this assemblage and discuss the impact of this recurring innovation in facilitating prey-capture by biting. Using character mappin...

The purpose of this study was to clarify the genetic contribution to finger-sucking and nail-biting in childhood using the largest databases available on Japanese twins. The subjects were 1131 pairs of 12-year-old twin children, consisting of 1057 males and 1205 females. All data were gathered by maternal questionnaire, and responses to the questionnaire were checked in the medical interview. T...

The seasonal abundance, night indoor biting behavior and parity of Culex quinquefasciatus were investigated for a period of one year from June 1988 to May 1989 in Mysore City. Twelve-hour night-time biting catches were carried out from 1800-0600 hours at four selected urban localities. The biting cycle revealed that Cx. quinquefasciatus was active throughout the night, with peak activity at 220...

The mosquito sampling efficiency of light-trap catches and electric motor mosquito catches were compared with that of human biting catches in the Three Gorges Reservoir. There was consistency in the sampling efficiency between light-trap catches and human biting catches for Anopheles sinensis (r = 0.82, P<0.01) and light-trap catches were 1.52 (1.35-1.71) times that of human biting catches rega...

Introduction: Stereotypic behaviors are characterized by repetitive, deviated and aimless actions that persist for more than 4 months in individual. Nail biting habit is one of informed obsessive-compulsive disorders that begins in childhood and continues for a long time. Onychophagia is a disorder with unknown cause and many factors can predispose it in a child. Individual characteristics and ...

Objective To assess the variation in Anopheles darlingi’s biting activity compared to An. marajoara in the same locality and to biting activity data from other regions. Methods Using human bait, eight observations of the biting activity of An. darlingi and An. marajoara were carried out during 1999 and 2000 in the municipality of São Raimundo do Pirativa, state of Amapá, Brazil. Each observatio...
