隐斑瓢虫是近年来在杭州地区发现的日本松干蚧的一种重要捕食性天敌。该虫在杭州一年发生四代，其年发生规律基本上和日本松干蚧的生活周期相吻合，而且能在松林中形成比较稳定的群落。

Vitamin B2 (VB2) was determined monthly in twigs and leaves of Sophora japonica, the most favorable host of the scale insect.

作者于1998～1999年在太原市和太谷县城设点，测定了该蚧虫的寄主树木国槐体内维生素B2(VB2)的变化规律，用蚧虫的虫口密度和生物学节律相对照，分析了污染－VB2含量－蚧虫种群消长之间的关系。

Ecological environment factors affecting its growth and development and the spatial distribution characteristics of plant autoeciousness of Hemiberlesia pitysophila were comprehensively analyzed by combining Maxent ecological niche models with geographical information system technique in this paper.The relatively exactly potential distribution region of Hemiberlesia pitysophila in whole Chi...

本文选用Maxent生态位模型与地理信息系统相结合，综合分析影响松突圆蚧生长发育的环境因素，结合寄主分布特征，非常直观定量地获得了松突圆蚧在我国的潜在发生区，计算结果经ROC曲线分析法验证，Maxent生态位模型的AUC值为0.991(非常接近于1)，表明预测获得了较好的效果，研究可为松突圆蚧的检疫及防治决策的制定提供科学依据。

The results of the study on the occurrence, distrbution and natural control effect of fourteen parasitic wasps parasitized on two scales in Zhejiang citrus planting areas are presented. The results indicated that Microterys flovus How., M. ceroplastae Prirtsloo, M.sp and Metaphycus pulvinariae How. of Encyrtidae and Coccophagus iycimnia of Aphelindae are predominant, the rate of parasitism is 80-100%. If any one of the above mentioned five species of parasitic wasp is occurred in the orchard, the damage caursed by those two scales could be controlled.

本文对浙江桔区这两类蚧虫的14种寄生蜂的发生、分布及其天然制约作用进行了深入研究，以跳小蜂科的软蚧花翅跳小蜂、蜡蚧花翅跳小蜂、黑褐花翅跳小蜂、软蚧阔柄跳小蜂和蚜小蜂科的赖食软蚧蚜小蜂为优势种，寄生率高达80%～100%，在桔园只要有上述5种中任何一种寄生蜂存在，足以控制两类蚧虫为害。
