摘要
本文系统地研究了柿绵粉蚧(phenacoccus perqandei Ckll)的生物学,主要包括:生活史、生物学特性,此外连续二年(1990~1991)在果园对害虫防治,均取得良好效果,虫口可降低90%以上.结果表明:全世代中以一龄若虫孵化盛、末期为化学防治的最佳时期。而40%氧化乐果乳油的防治效果最好。
This study was conducts to investigate the life history,biological characteristics of Phenacoccus perqadei Ckll. A series of chemical control experiments were carried out during different development stages of pest.
