摘要:
在江苏省宿迁地区,紫薇绒蚧(Eriococcus lagerostroemiae)是危害紫薇(Lagerstroemia indica Linnaeus)最严重的害虫之一。本研究发现,紫薇绒蚧在宿迁每年发生3代,以若虫和雌成虫的形式在紫薇树体上越冬。第二年4月下旬先后化蛹、羽化,进行交配和产卵。若虫每年有3个发生高峰期(5月下旬至6月中旬、8月上旬至8月中旬、9月下旬至10月上旬),紫薇绒蚧防治的重点时期在4月下旬越冬若虫活动高峰期和6月中旬若虫成熟高峰期。研究结果表明,春季防治以5波美度石硫合剂的效果最好,夏季防治首选2.5%高效氯氟氰菊酯+5.0%阿维菌素300倍液。
Abstract:
Eriococcus lagerstroemiae is one of the most important pests causing severe damages to Lagerstroemiae indica Linnaeus in Suqian, Jiangsu province. The research results showed that Eriococcus lagerstroemiae completed three generations every year and overwintered in nymphs and female adult in the host twigs. Until late April of the next year, they pupated, emerged, mated and laid eggs. Three peaks of nymphs occurrence were recorded from late May to mid-June, early to mid-August and late September to early October, respectively. The proper control period was late-April when nymphs appeared frequently and mid-June when nymphs matured. Five baume degrees LSSS showed the best control effect on the pest in the spring, while 2.5% lambda cyhalothrin + 5.0% avermectin (300 times diluted) was the best choice in the summer.
