瓢虫

Harmonia axyridis Pallas (Coleoptera: Coccinellidae) with its native in Asia is one of the most important predatory ladybird beetles and used worldwide as a biological control agent.

原产于业洲的异色瓢虫是最重要的捕食性瓢虫种类之一，被广泛应用于农林业害虫的生物防治。

Any of numerous small, rounded, usually brightly colored beetles of the family Coccinellidae, often reddish with black spots and feeding primarily on insect pests, such as scale insects and aphids.

瓢虫任一种小而圆的通常具有鲜艳色彩的瓢虫科的甲虫，体常呈红色并带有黑色斑点，主要以介壳虫和蚜虫等害虫为食

The changed physiological parameters in the body of ladybird in every season caused these differences. The body weight including fresh and dry weight, content of fat and glycogen, activities of glutathione S-transferase in the body of H. axyridis all decreased gradually in overwintering. All these indices began to recircle after hibernation and would be up to the optimum status when they entered dormancy.

造成这种差异的原因是不同时期异色瓢虫体内的一些生理指标不一样，在越冬期异色瓢虫体重、脂肪和总糖含量逐渐降低，谷胱甘肽S-转移酶的活性也逐渐下降，出蛰后各项指标又开始回升，直至进入越冬时达到最佳状态。

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。

Based on the investigation of Propylea japonica reared in laboratory by using Aphis robiniae Macchiati , the hatching, ecdysising behaviors of the larva, the eclosion, hunting, mating and ovipositing behaviors of the adult, the cannibalism behaviors of the larva and the adult were observed and described.

中文摘要：通过以洋槐蚜 Aphis robiniae Macchiati 为食物对龟纹瓢虫 Propylea japonica进行室内饲养和观察，记述了龟纹瓢虫幼虫的孵化、蜕皮行为，成虫的羽化、捕食、交配、产卵行为，并对幼虫成虫的自残行为进行了初步观察。

70S in the 20th century the lower reaches of the Yellow River has started to move with helping to control the cotton and wheat aphid, 90 during the beginning of artificial propagation, and for the production.

七星瓢虫是鞘翅目瓢虫科的捕食性天敌昆虫，在我国各地广泛分布。20世纪70年代在黄河下游已开始用助迁法防治棉花和小麦蚜虫，90年代开始人工繁殖，并用于生产。

The tolerance of multicolored Asian ladybirds to high temperatures was stronger than that of aphids at 40℃ below.

40℃以下异色瓢虫对高温的耐受力比桃蚜强，超过40℃桃蚜的耐热力反而高于异色瓢虫。

Prized for farmers for their war on pests and by children for their delicate beauty, the beetles were known to Englishmen in the Middle Ages as ladybirds, creatures of Our Lady.

瓢虫己经得到农夫们的赞赏它们清除有害物，小孩子说它精巧漂亮，甲虫类在中世纪被英国人所了解特别是瓢虫，称呼它是我们的女士。

当我还是一个小女孩的时候，我曾经花很多时间去找瓢虫，然而最后我放弃了，在草地上睡着了，当我醒来时，我身上却爬满了瓢虫。

Grandis adult on peach aphid increased with the increment of peach aphid density when peach aphids were in 20 - 120 heads/dish, reached maximum （83.889 heads） and decreased when peach aphids were more than 120heads/dish.

方法在放有1头大突肩瓢虫成虫的培养皿中分别放20、40、60、80、100、120、140、160、180头无翅桃蚜，室内自然条件下饲养，研究大突肩瓢虫成虫对桃蚜的捕食作用。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
