Abstract:
The thermo-eclector with water jacket heating facilitates the collection of young Ixodidae from animals and is also applicable for obtaining Gamasidae from birds nests. The design features of the thermo-eclector provide for a mechanical collection of ticks. Their basic aim is to create for ticks unfavorable temperature conditions and a high degree moisture deficiency. The collection of ticks from smaller animals is realized by a miniature model, while driving the ticks off the big animals and collection of gamasides from nests is effected with the aid of a grand model. The use of a thermal relay makes it possible to select for the driving off operation optimal temperature conditions and to maintain them at a set level through out the whole period of the experiment. In driving off the D. nuttalli and D. pictus larvae good results were achieved with water temperature in the jacket bath kept at 42--43 degrees and in the bottom space - at 39--40 degrees I. persulcatus larvae -- at 28--30 degrees and 26--28 degrees respectively D. marginatus nymphs with the grand model at 50--52 degrees and 42.5--44 degrees respectively. Optimal conditions for driving gamasides off the nests H. casalis, gamasides of the starling nests - provide for the temperature in the jacket of the grand model equalling 42--45 degrees. For driving off with the aid of a miniature model from a fairly dry material it suffices to set the thermal relay contactor at 35--36 degrees. The grand model is suited better for driving the gamasides off the nests.
