Dose‐response data were obtained after treatment of eggs of Cydia pomonella and Cydia molesta with five synthetic analogues of insect juvenile hormone. All prevented hatching of the eggs, but at different concentrations. The most effective ovicide was ethyl 3, 7, 11‐trimethyl‐2, 4‐dodecadienoate which had LD50 values of 0.012% and 0.014% against the two species respectively. The sensitivity of eggs to this ovicidal action remained high during the first two days of embryonic development at 28°C, and then decreased greatly. The potential of juvenile hormone analogues as control agents for these insect pests is discussed.
