Synthesis of Phenoxyphenyl Pyridine and Pyrazine Carboxamides. Activity against Cydia pomonella (L.) Eggs
摘要:
Several N-(4-phenoxyphenyl)pyridinecarboxamides and N-(4-phenoxyphenyl)pyrazinecarboxamides were synthesized from commercially available material, and their ovicidal activities against Cydia pomonella (L.) were tested. Some of the tested products showed a moderate activity when <24-h-old eggs were sprayed using a Potter tower. A significant increase in the length of the development also observed in many cases. A clear correlation between both effects was period of the eggs was noticed: the products that produced higher mortality also produced higher increase of the length of the development. These results seem to confirm our hypothesis that these compounds could be defined as a juvenile hormone analogues.
