[Trial of the action of synthetic juvenile hormone analogs on fleas]

H-chlorphenyl ether of geraniol (1.5 to 0.05 %) caused the mortality of all preimaginal stages of fleas of the species C. anisus. 0.025 % dose of the preparation broke the normal course of metamorphosis that resulted in the delay of moulting periods of larvae, the formation of cocoons and hatching of imagos. All these deviations reduced the emergence of adults by to 90 %.
