按蚊的

Purpose: To observe the fecundity and longevity of Anopheles sinensis under the condition of daily supply of blood meal.

钟格梅；谭毅摘要：目的：在实验室内观察每天供血中华按蚊的生殖与寿命特性。

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。

The morphological and molecular variations between AK and AL were small and belong to intraspecific level.

两种按蚊形态特征和分子序列差异极小，应属种内变异范围，可以确认两者是同一蚊种，昆明按蚊为凉山按蚊的同物异名。

The population of this group takes a 42.68% share of the whole anopheline population in the mountain areas.

伪威氏按蚊和多斑按蚊的人血指数分别为4288％和3571％，其密度的季节消长与疟疾流行关系密切

Methods With deltamethrin impregnated bednets and alphamethrin residual spraying and bednet impregnation to control malaria vectors,observe the change of density of An anthropophagous and Ansinensis and malaria incidence and calculate the costs.

采用溴氰菊酯浸帐灭蚊和浸帐加氯氰菊酯滞留喷洒的方法防制疟疾媒介，观察嗜人按蚊、中华按蚊的密度变化和疟疾发病率，按照人均所需费用核算成本。

The melanotic encapsulation of oocysts is a specific immune defence mechanism against Plasmodium infection ,and is also a primary phenotype in the Plasmodium-refractory strain of An.gambiae.

卵囊黑化包被反应是按蚊抵御疟原虫感染的特异性免疫防御机制，也是抗性株冈比亚按蚊或不易感按蚊的最主要表型。

OBJECTIVE ①To compare the sequences of the ribosomal rDNA-ITS2, 28S-D3 and mitochondrial mtDNA-COII in the different origins of Anopheles minimus for detecting the intra-and inter-specific variation of the sibling species of the Minimus Complex;②To reconstruct phylogenetic trees of the Minimus Complex and Myzomyia Series for determining the position of An. minimus A and C;③To establish specific methods for differentiation of two sibling species, An. minimus A and An. minimus C, of the Minimus Complex.

中文题名微小按蚊种群变异与分子鉴别研究副题名外文题名论文作者周水森导师汤林华研究员学科专业分子流行病学研究领域\研究方向学位级别博士学位授予单位中国预防医学科学院学位授予日期2002 论文页码总数98页关键词蚊微小按蚊馆藏号BSLW /2003 /R384 /3 目的①比较微小按蚊核糖体rDNA-ITS2、28S-D3基因和线粒体mtDNA-COII基因的序列差异，阐明微小按蚊复合体亲缘种种间和种内变异；②根据基因变异重建微小按蚊复合体及迈蚊系成员的种系发生关系，以确立微小按蚊亲缘种变异的种系地位；③建立微小按蚊复合体亲缘种A和C的分子鉴别方法。

It's breeding and reproduction were remarkably affected by rainy season.There was no notable difference on the density and the parous rate between An.Dirus in the village where the nets were impregnated with deltamethrin and that in the control village.

山寮叮人率是村内叮人率的15倍，自然感染率可高达8.3%，雨季对大劣按蚊的孳生繁殖有极大的影响，溴氰菊酯浸帐村与对照村的大劣按蚊密度和经产蚊比率无显著性差异，在当地多种因素影响下，溴氰菊酯浸帐防制大劣按蚊的效果不理想。

When she jabs her proboscis into a person's epidermis to drink blood, she sprays the bite area with saliva that serves as an anticoagulant. If her last victim had malaria, that saliva will contain one-celled malaria parasites called plasmodia, a couple of dozen of which can enter the human bloodstream. But it only takes one to kill a person.

当按蚊的雌蚊猛刺进人的皮肤吸血时，还会喷射抗凝剂，假如它叮咬的是患有疟疾的病人，那么雌蚊也就把疟原虫吸进它的体内，然后她又去叮咬其它的人，又把雌蚊体内的疟原虫传播到另外的人造成新的疟疾病人。

It is possible from the above investigations, AsSP1 and AsSP2 might be correlated with the plasmodial infeetion or the melanotie eneapsulation of P.

结论AsSP1和AsSP2很可能与疟原虫感染或约氏疟原虫卵囊黑化相关，推测可能是斯氏按蚊的前酚氧化酶的活化酶。

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。
