studies on the biting behavior of the more common species of anophelines were carried out in ghasreghand, chabahar (sistan & baluchistan province) from may 1990 to march 1991, in which outdoor human and animal (cattle) biting collections were made between 18.00 hr and 5.00 hr in a total of 13 rounds. in addition, blood smears from anophelines captured in pyrethrum space-spray catches of human a...

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...

The aim of this study was to test the hypothesis that experimental and reversible changes of occlusion affect the levels of surface electromyographic (SEMG) activity in the anterior temporalis and masseter areas during unilateral maximal voluntary biting (MVB) in centric and eccentric position. Changes were achieved by letting 21 healthy subjects bite with and without a cotton roll between the ...

Previous reports have indicated that biting behavior is enhanced in rats that are subject to acute stress. Several methods have been proposed for studying this phenomenon, one of which is the electromyography (EMG) of the jaw muscles. In this study, we compared total EMG activity with the EMG activity related to biting behavior, as determined by video monitoring, before and after restraint stre...

Recently, we showed that infection with dengue virus increases the locomotor activity of Aedes aegypti females. We speculate that the observed increased locomotor activity could potentially increase the chances of finding a suitable host and, as a consequence, the relative biting rate of infected mosquitoes. We used a mathematical model to investigate the impact of the increased locomotor activ...

Objectives: The study was carried out to assess the analgesic, anti-inflammatory, and CNS depressant activity of the methanolic extract of  the Lawsonia inermis barks(MELIB). Materials and Methods: Anti-inflammatory effects of MEBLI were studied using carrageenan-induced inflammatory method at the dose of 300 and 500 mg/kg b.wt., p.o. Analgesic activity was measured using acetic acid-induced wr...

How does motor neuronal variability affect behavior? To explore this question, we quantified activity of multiple individual identified motor neurons mediating biting and swallowing in intact, behaving Aplysia californica by recording from the protractor muscle and the three nerves containing the majority of motor neurons controlling the feeding musculature. We measured multiple motor component...

The daily man-biting activity of Anopheles (Nyssorhynchus) albimanus and An. (Kerteszia) neivai was determined in four ecologically distinct settlements of the Naya River, Department of Valle, Colombia. Differences were found among the settlements with respect to the mosquito species present, intradomiciliary and extradomiciliary biting activity and population densities.

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...
