[Effect of the bacterial preparation, insectin, on the fleas Xenopsylla cheopis].
The effect of 0.2-2 mg/g of insectine (Bacillus insectus) upon the Ist-IInd stage larvae of X. cheopis is very negligible but it manifests itself in the subsequent low (9 to 30%) development and hatching of imagos. The III stage larvae are more resistent and after the effect of 10 mg/g of the preparation 9% of larvae formed cocoons which later developed into imagos. Adult fleas poorly responded to 0.2-2 mg/g of insectine. However, 10-30 mg/g of insectine caused in four days a mass death of fleas and their population decreased to 70% as compared to control.
