Summary

Three juvenile hormone analogs (JHA), an acyclic terpene (ACT) [ethyl-3,7,11-trimethyldodeca-2,4-dienoate], a non-terpenoid compound (NT) [acetaldehyde-2-(2-ethoxyethoxy)-ethyl-4-(methylthio)-m-tolyl acetal], and an aromatic terpenoid ether (ATE) [1-(4-ethylphenoxy)-6,7-epoxy-3,7-dimethyl-2-octene] were studied to determine their effect on the embryonic development ofHyalomma (H.) dromedarii. ACT completely blocked embryonic development of eggs that had not yet reached the vitellogenesis stage or were in this stage at the time of ACT application to the female. Development of eggs between vitellogenesis and ovulation stages was partially blocked. Embryogenesis was more or less blocked by NT and ATE, except in a few egg batches from females that had received high NT doses. F1 larval mortality after JHA application to parent females was 100% with ACT, 5 to 100% with NT, and 5 to 85% with ATE.
