瓢虫

Harmonias axyridis is one of important predatory natural insect for controlling Eriosoma lanigerum in apple orchards.

异色瓢虫是苹果绵蚜的主要捕食性天敌昆虫，其在苹果园的初发期在2~3月，高峰期在3~4月。

The bees, gorged with honey and no longer protecting their brood, are as docile as ladybugs.

此时，这些拼命地采蜜而疏于保护幼蜂的蜜蜂就像瓢虫一样驯服。

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。

Natural resources, pest and 2 Class 7 orders, 30 families of 96 to ladybird, red eyes peaks, such as flowers Pentatomidae found.

害虫天敌资源有2纲7目30科96种，以瓢虫、赤眼峰、小花蝽等多见。

LetS conside some of the insects found in the house,appaently attempting to escape into the snowy landscape--vitually any winte window,late in the season.shouldpovide good collecting if you quay includes ladybidbeetles,polistes wasps,cluste flies,o elm.1eaf beetles.

让我们看一下在房子里发现的一些昆虫，它仃J显然想遁入雪地中--事实上，晚冬时倘若你留心，可以在任何一扇冬天的窗户上发现云集着好一些昆虫，有瓢虫、长足胡蜂、粉蝇或榆黄守瓜，它们将成为很好的标本。

The accumulative survivals from egg to pupal stage of all treatments decreased significantly.

说明低剂量的杀虫剂对异色瓢虫的繁殖活动具有不同程度的抑制作用。

The structure and 5-HT immunoreactivity in the brain and suboesophageal ganglion of three beetle s, Ambrostoma quadriimpressum, Henosepilachna vigintioctomaculata and Oxycetonia jucunda, were first studied by means of colophony-paraffin embedding serial section technique and strepteavidin-peroxidase immunohistochemical method.

采用树脂石蜡组织包埋连续切片技术，结合免疫组化链霉菌抗生物素蛋白-过氧化物酶染色法，首次对三种甲虫(榆紫叶甲、小青花金龟、马铃薯瓢虫)的脑进行了详细观察研究，分析了三种甲虫脑组织结构特征，初步构建了三种甲虫脑内5-HT抗原系统免疫组化反应模式。

The structure and 5-HT immunoreactivity in the brain and suboesophageal ganglion of three beetles, Ambrostoma quadriimpressum, Henosepilachna vigintioctomaculata and Oxycetonia jucunda, were first studied by means of colophony-paraffin embedding serial section technique and strepteavidin-peroxidase immunohistochemical method. The results showed that the brains of these three taxonomically closely related beetles were remarkably different in composition and size.

The central complex isprominent. The beetle showed notable 5-HT-like immunoreactivity throughout the wholebrain, which was also strongly labelled by TPH antibody, with the pattern matching that of5-HT. 5-HT-like positive fibers were resolved in all areas of the brain, among which thelamina and suboesophageal ganglion showed the most remarkable dark brownimmunostaining. While, all major neuropil regions, in general, showed low level backgroundafter TPH immunostaining for TPH mainly existing in cytoplasm. The number of 5-HT-likeimmunoreactive neurons was relatively small but possessed extensive varicose arborizations.

免疫组化结果显示，异色瓢虫脑系统呈强5-HT免疫反应，表现为稳定的反应模式；其脑系统对鼠抗TPH单克隆抗体同样呈显著的免疫阳性反应，且反应模式与5-HT一致。5-HT能神经元多为切向神经元，数目相对较少，呈两侧对称分布，主要位于视叶与侧前脑之间、前脑背方及咽下神经节处，其阳性纤维呈明显的静脉曲张状，投射区域较广泛。

ITS2(Intemal Transcribed Spacer 2) region in ribosome DNA has a character of conservative that makes a low aberrance ratio, on the other side, ITS-2 region evolves itself. According to the characters, ITS-2 region sequencing is an effective parameter in taxology and pests-control..

核糖体基因的第二内转录间隔区有较高的保守特性，同时进化速度又较快，因此序列进行测序得出的种内差异，是系统发育学的有力参数，也有助于异色瓢虫分类学和农林虫害的防治。

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).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
