In recent years, the tortoise wax scale (Ceroplastes japonicus) has spread through the counties of our city, causing serious damage, which has generally weakened the vigor of jujube trees, significantly reduced yields, and even caused total crop failure. In order to effectively carry out chemical control of the tortoise wax scale on jujube, since 1996 we have carried out control trials for 4 consecutive years
