海南桉树枝瘿姬小蜂成虫羽化量的研究

摘要

In order to investigate the occurring rule of Leptocybe invasa Fisher & La Salle in Hainan province, this article investigated the yellow hoard of Leptocybe invasa Fisher & La Salle and statistic the amount provided indoor at first. Then evaluating the damage of eucalyptus and population dynamics of victims for five sites of Hainan province. Finally, the study found that there were significant difference in introduced the degree of Leptocybe invasa Fisher & La Salle and population happen for different varieties and different seasons. There was a significant difference in feeling insect degree of varieties eucalyptus. The DH201 (Eucalyptus urophylla~ E. Camaldulensis) and Eucalyptus camaldulensis Dehnh had the most heavy feeling insect, then was the eucalyptus mixed forest, the next was the GL9.%通过对桉树枝瘿姬小蜂野外黄板调查以及室内羽化量的统计,调查桉树枝瘿姬小蜂在海南发生危害规律,评价海南省5个地点的桉树周年受害情况和种群动态,从而得出不同季节和不同桉树品种受到桉树枝瘿姬小蜂的危害程度和种群发生存在显著差异。不同桉树品种感虫程度存在显著的差异性,感虫程度由重到轻依次为：尾赤桉DH201无性系=小叶桉〉桉树混合林〉广林9号。
