Experiments have established that the pyrethroids deltamethrin and cypermethrin (decis and cimbush) may be used in the Siberian natural plague foci for not only emergency, but also early prevention of plague. This substantially expands and simplifies the possibility of organizing disinfection actions and reduces the cost of treatments. The findings are determined by the specific features of the biology and ecology of fleas inhabiting in the natural plague foci of the souslik type in a continental climate area. The specific features include the coincidence of preimago stages and the larger proportion of an adults to rodent nests; the low migration of imagoes from the inhabiting nests to the ground surface, only one insect generation that can develop within a comparatively short (4-5-month) warm period of a year. |
