Oviposition and incubation in Boophilus decoloratus (Koch, 1844) (Acarina: Ixodidae).
نویسنده
چکیده
Studies on the duration of the oviposition and incubation periods of Boophilus decoloratus (Koch, 1844) revealed that these non-parasitic periods are temperature dependent, increase in temperature causing shortening of the periods. Humidity had no effect on duration of either the oviposition or the incubation periods. The relation between the mass of engorged female ticks and that of the eggs they produced was found to be linear. The viability of eggs produced during the first 13 days of oviposition (at 26 degrees C) was greater than that of eggs laid subsequently. The critical temperature for B. decoloratus eggs was found to be 42 degrees C and they were shown to be unable to take up water vapour from damp atmospheres. Both temperature and humidity affected the hatch of eggs. A simple model of the relations between the physical factors of the environment and the various biological phenomena studied has been given.

The prehatch period and larval survival of Boophilus decoloratus (Koch, 1844) (Acarina: Ixodidae) under natural conditions in the Transvaal, South Africa.
Studies were made on the duration of the prehatch period of Boophilus decoloratus and on the subsequent survival and viability of larvae under natural conditions. The length of the prehatch and larval survival periods was found to be inversely dependent on increased temperature. A high initial temperature at the time of female drop decreased the prehatch period further, resulting in synchronous...

Efficacy and toxicity of aqueous and organic solvents extracts of Maerua edulis against ticks and mice, respectively, were determined. Ground leaves were extracted separately using cold water, cold water plus surfactant (1% v/v liquid soap), hot water plus surfactant, hexane, or methanol to make 25% w/v stock solutions from which serial dilutions of 5, 10, 20, and 25% were made. For each concen...

The objective of this study was to determine certain aspects of the biology of Rhipicephalus (Boophilus) decoloratus larvae under laboratory and field conditions. Larvae allowed 48 h to select a vertical questing substrate preferred 90 cm rods in length to those of 60 or 30 cm, while in a separate experiment migration from rods 5 cm or 25 cm in length to rods 45 cm in length continued between 4...

Herein, Amblyomma tenellumKoch, 1844 (Ixodidae) is reestablished as a valid tick name and removed from the synonymy list of Amblyomma cajennense (Fabricius, 1787), while Amblyomma imitatorKohls, 1958, is relegated to a junior synonym of A. tenellum. Amblyomma tenellum is redescribed based on the examination of male type specimens collected by Deppe at the beginning of the 19th century in Mexico...
