摘要
生物学研究表明,花椒桑拟轮蚧在滇东北部1年发生2代,以受精雌成虫在树皮蚧壳内越冬,第2年4~5月份产卵。繁殖力与海拔高度密切相关。若虫期可用40%速扑杀乳油600倍液喷施于枝干,防效可达80%以上。自然防效较强,建议采用综合防治方法加以控制。
Studies on the biology of White mulberry scale, Pseudaulacaspis pentagona ( Targioni ), showed that 2 generations occurred in pepper plantations in East North Yunnan each year. And the mated adult females over winter on bark and oviposited in May or April of the next year. Its reproductive potential was closely to altitude. The effect of control was 80% or higher by spraying the branches on pepper with 40% Supracide 600× at nymphal stage; meanwhile, nature enemies had high capability of control ; so pest management.
