Camellia. In addition, some circumstantial evidences show that some insect-eating birds such as Pycnonotus sinensis and Lanius schach were predators of larvae of D. camellia.

另外通过间接证据，提出了白头鹎Pycnonotus sinensis和伯劳Lanius schach等食虫鸟类是油茶史氏叶蜂幼虫重要捕食性天敌的初步结论。

Results show that the insect community structure in the Bt fields differed sharply from that in the CV fields. The populations of the Lepidopterous pests, such as cotton bollworm, corn borer, diamond bollworm and cotton leaf caterpillar, decreased significantly in the BT fields, while the populations of non-target pests with piercing-sucking mouthparts, such as leaf bugs, cotton spider mites, cotton aphids and whiteflies, increased obviously. Much more predators, such as spiders and ladybirds, and much less parasitiods of Helicoverpa armigera were observed in the BT fields.

结果表明，与常规棉田相比，Bt棉田棉铃虫、玉米螟、金刚钻、棉小造桥虫等鳞翅目害虫种群数量显著降低，而盲蝽象、红蜘蛛、棉蚜、烟粉虱等非靶标刺吸式害虫种群数量显著增加；蜘蛛、瓢虫等捕食性天敌种群数量显著增加，而棉铃虫的寄生性天敌种群数量则显著下降。

The aim of the present study is to evaluate the biological control aptitude of the cyanobacteria, Anabaena subcylindrica, Nostoc muscorum and Oscillatoria angusta filtrates on the growth of the isolated pathogenic fungi from the different organs of Faba bean.

生物防治」是指以人为方式利用一种生物对抗另一种生物的方法，包括微生物防治，寄生性天敌防治，捕食性天敌防治等，这种方法最大的优点就是不会污染环境。

Based on a systematic field investigation and laboratory experiments, the structures of arthropod communities and the evalution of dominant predatory enemies in cabbage fields of different seasons were studied. The main results were as follows:1 The structures and their dynamics of arthropod communities in cabbage fields1.1 Species composition and population dynamics of each species of the arthropodcommunities in the cabbage fieldsThe research results showed that the occurrence of Pieris rapae in spring cabbage fields was relatively grave.

本文在田间系统调查和室内试验的基础上，对不同季节甘蓝田节肢动物群落结构及捕食性天敌优势种的评价进行了研究，主要结果如下：1甘蓝田节肢动物群落结构及其动态1.1节肢动物群落物种构成和各种群数量动态研究结果表明，春甘蓝田菜青虫的发生比较严重，菜青虫在调查期间种群数量呈上升趋势，5月初高峰期平均每株甘蓝接近20头；菜蚜与小菜蛾的发生相对较轻，菜蚜在5月中旬有个明显高峰。

The temporal and spatial niche breadth value of Propylaea japonica was maximum, and the temporal niche overlap value of Theridion octomaculatum between dominant predatory enemies and Aphis gossypii was maximum and the spatial niche overlap of Pardosa T-insignita was maximum.

对淮北棉田节肢动物优势种群组成和时空生态位进行分析，结果表明：棉蚜、烟粉虱、棉叶螨、棉盲蝽、四点亮腹蛛、龟纹瓢虫、T-纹豹蛛、草间小黑蛛、八斑球腹蛛、华姬猎蝽、小花蝽和青翅隐翅虫为优势种群；时间和空间生态位宽度值都是以龟纹瓢虫最大，捕食性天敌优势种群与棉蚜时间生态位重叠值以八斑球腹蛛最大，空间生态位重叠值以T-纹豹蛛最大。

Under the laboratory conditions of natural temperature , several kind of predacious ladybugs were fed. We had an detailed observation to their life habit and predatory function to aphids.

在实验室自然变温条件下对几种捕食性瓢虫进行人工喂养，对其生活习性以及对蚜虫的捕食量进行详细的观察记录。

The experimental result indicated that the predacious ladybugs'generation period is between 11 to 18 day, the female daily egg production is different in the 10~40 between July to August in Laiyang area of Shandong province.

实验结果表明在山东莱阳地区7.8月份的自然温度条件下捕食性瓢虫的世代历期为11-18天，成虫单雌每天产卵量在10-40粒不等。
