Emploi de pièges et d'écrans dans la lutte contre la trypanosomiase animale au Togo
Abstract
Use of traps and screens in the control of animal trypanosomiasis in Togo. Traps and screens impregnated with remanent insecticides (deltamethrine) were used around the "Centre de Recherche et d Elevage d Avetonou" (Togo) to combat animal trypanosomiasis. Preliminary results obtained after 12 months are promising : not only the glossina density per trap-day decreased from 4.6 in December 1985 to 0.1 in December 1986, but also the trypanosomiasis infection rate went from 13.6 % down to 1.66 for the same period. On the other hand, the same rate of the control herd varied only from 10 % to 10.4 % in the untreated area but some improvement in the productivity (less abortions and calf mortalities, more calvings, ...) was noticed where traps and screens were used. The cattle was of the trypanotolerant type.
