按蚊

Density of Anopheles kept in low level.

按蚊密度维持在较低水平。

These tools were used to do study on life table of natural population of Anopheles sinensis.

应用这些工具进行了自然界中华按蚊种群生命表的研究。

Objective To evaluate effectiveness of mosquito control measures in "Anopheles anthropophagus" area.

目的 评价嗜人按蚊分布区不同灭蚊措施的疟疾防制效果。

Objective To evaluate eitectiveness oi mosquito control measures in Anopheles anthropophagus area.

目的评价嗜人按蚊分布区不同灭蚊措施的疟疾防制效果。

The results of our research showed that the chinaberry seed oil, two emulsion formulations of crude toosendanin, Margosan-O, azadirachtin, AZT(NR-2), AZAL-S, petrolem ether extract of the leaf of Tagetes erecta, methyl extract of the root of Tagetes erecta, methyl extract of the whole plant of Bidens pilosa, the oil of Ageratum conyazoides and polygodial had potent toxicity to the larvae of Anopheles sinensis, Culex quinquefasciatus and Aedes albopitus.

中华按蚊Anopheles sinensis、致倦库蚊Culex quinquefa-sciatus和白纹伊蚊Aedes albopictus都是我国重要的传病蚊种。本研究首次证实下列植物的提取物对上述三种蚊虫有毒杀作用：(1)苦楝：苦楝油；(2)川楝：川楝素乳剂、蔬果净；(3)印楝：Margosan-O、印楝素、AZT(NR-2)、AZAL-S；(4)万寿菊：叶石油醚提取物、根甲醇提取物；(5)三叶鬼针草：整株植物甲醇提取物；(6)百花草：精油；(7)水蓼：Polygodial。

Those mosquitoes were taken back to category and analysis. Results Seven species of mosquitoes were found in pig houses,of which Culex tritaeniorhynchus was dominant species.

结果在猪圈内捕获7种蚊虫，其中三带喙库蚊是优势种；按蚊的发生高峰在6月中旬，阿蚊的发生高峰在9月下旬，库蚊有两个高峰，分别发生在7月上旬和8月底9月初。

Deltamethrin imˉpregnated bednets can effectively decrease the density of An anthropophagous to control malaria and can save0.58Yuan per person compared with alphamethrin residual spraying and bednet impregnation.

溴氰菊酯浸帐灭蚊能有效降低嗜人按蚊密度，控制疟疾发病，比浸帐加滞留喷洒灭蚊人均节约经费0.58元。

In order to reach this goal,the primary basic research work is to clone,evaluate and analyse the function of the genes that support or impact the development of malaria parasites in the mosquito vecter and the study on the mechanisms of innative immune defence responses against Plasmodium infection.

于上世纪九十年代，WHO提出了基因操纵蚊媒的新策略，而寻找支持或抑制疟原虫在蚊体内发育的相关基因，克隆、鉴定及分析其功能，以及研究按蚊抗疟原虫感染的先天性免疫反应机制是实现这一策略的重要前提。

It is effective against mosquitoes, blackflies and some midges; c ontrols v arious t ypes o f

一般 ，它对库蚊、伊蚊、骚扰阿蚊较敏感，对中华按蚊较差。它有效地防治黑蝇和蠓

Methods The drug is given to rhesus monkey by the intramuscular injection, first dose duplicate followed by a single dose at 24,48,72,and 96hrs for 5 days, the total doses are given respectively as 15.0mg/kg, 7.2mg/kg, 3.6mg/kg, 1.8mg/kg. Experimental animal was bitten by Anopheles dirus before giving drug, and at 6,12,24,30,36,48,54,60,72,84,and 108hs later, mosquites were examined for oocysts on day 9 and sporozoites on day 13 after infection.

方法首剂药量加倍，随后24，48，72和96小时给实验猴各肌注一次，疗程5天，总剂量分别为15.0mg/kg、7.2mg/kg、3.6mg/kg、1.8mg/kg；在给药前及给药后6、12、24、30、36、48、54、60、72、84和108小时各用一批大劣按蚊叮咬实验猴，叮咬后第9天解剖蚊胃，第13天解剖涎腺。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
