Abstract: Apriona germari is one of the important stem boreres of clones of the Aigeiros poplars. The biological character of the adult shows that it has to feed on the bark of branches of the mulberry or paper mulberry to complete its life cycle. Three kinds of microencapsulated Decamethrin, Fenvalerate and Sumithion had been developed to spray on the mulberries during the emergence of the adults. Their residual effects maintained more than 15 days in the rainy season. Microencapsulated Decamethrin, Fenvalerate maintained more than 30 days and Sumithion microencapsule maintained 15 days in the rainless region. The results of these microencap-sules are better than their corresponding emulsions.
