化学感受这一重要的生化过程对于昆虫的生存来说是十分必要的,昆虫的化学感受受体家族由气味(嗅觉)受体和味觉受体组成。嗅觉可以识别挥发性的化学物质,使昆虫发现食物、寻找配偶和逃避敌害;而味觉能识别可溶性刺激物,以引起觅食、交配和产卵等行为。文章主要介绍了昆虫气味受体及味觉受体家族的特性,以及目前对多种昆虫化学感受受体超家族的研究进展。  相似文献

昆虫转基因研究进展、应用和展望   总被引:3,自引:0,他引:3  
自1982年Spradling和Rubin发现了可作为载体的P转座子并将外源基因成功地转入果蝇胚层系细胞的染色体而得到表达以来,昆虫转基因研究已经取得了长足进步.作为现代昆虫分子生物学中最为基本的技术之一,昆虫转基因技术不仅是分析昆虫基因功能的有力工具,而且在害虫防治、减少人类疾病载体昆虫携带的病原体的传播以及作为生物反应器等方面的作用亦日趋重要.  相似文献

昆虫是与我们息息相关的一个庞大类群,昆虫的起源进化是动物系统学研究的一个重要领域,其研究主要根据历史记载、化石记录、形态学和细胞学观察以及通过应用免疫学、生态学、遗传学等领域的技术来进行.近年来,分子生物学、计算机技术以及几类遗传标记的发现和应用为生物进化和起源的研究提供了新的切入点,即从分子水平上直接研究昆虫进化.  相似文献

Veterinarians have obligations towards both the animals they treat and their clients, the owners of the animals. Veterinarians have complicated, and often conflicting, relationships with both groups. In this article, Q-methodology was used as a method for discourse analysis to determine how Dutch large animal practitioners conceptualize animals and their owners and their professional responsibilities towards both. The article focuses on four different perspectives that Dutch veterinarians have of their animal patients and their owners, and of their professional duties and responsibilities.  相似文献

Cat owners commonly consider their pets to be members of their families, and many factors contribute to a high level of owner attachment to their cats. Suppression of a cat's emotional needs in favour of the emotional requirements of the owner may produce a less satisfactory relationship for the owner, and usually for the cat as well. Owners' failure to comprehend their cat's true demands of life, and their false expectation of their ability to fulfil human psychological demands lies at the heart of many feline behaviour problems.  相似文献

Students in animal science and veterinary science at the University of Queensland (UQ) have similar introductory courses in animal handling in year 1 of their degree programs. Veterinary students take animal-handling instruction in farm and companion animals, whereas animal science students are instructed in handling farm animals, horses, and rodents. Veterinary students are introduced to rodents, and animal science students to dogs and cats, in subsequent years of the curriculum. Both cohorts receive additional training, with clinical emphasis for veterinary students in years 3, 4, and 5 of their five-year curriculum. The introductory course is well received by students; both student cohorts appreciate the opportunity provided and the effort that goes into the animal-handling classes. Undergraduates realize that acquiring animal-handling skills will increase their proficiency in their subsequent careers; veterinary graduates recognize that their handling prowess will give their clients confidence in their abilities. Most clients cannot judge the competence of a veterinarian's diagnosis or treatment but will judge their ability based on their handling skills. Ongoing practice allows students to become competent in animal handling.  相似文献

与男生相比,女大学生的人际交往有其自身的特点,主要表现在交往动机理想化、交往圈子生活化和交往行为技巧化三个方面。这三个特点决定了女大学生的人际关系状况对其心理上的影响要比男生更为强烈。  相似文献

本文分析比较了165头超排荷斯坦母牛及其184头女儿的超排反应。从所有母女的整体看,在不同超排反应组,有一种趋势,即在不同反应分组中,母亲与女儿之间,似乎存在一种弱相关(r=0.20)。但在母女不同超排反应的组间,并没有这种相关,即在同一超排反应的母亲组,其相应的女儿组并不存在这种趋势。同一头母亲的2头或3头女儿,似乎母亲超排效果差,女儿的超排效果反而好,而母亲超排反应好,女儿的反应却有降低的趋势。由此得出结论,不能将母亲的超排反应结果作为选择其女儿超排反应的依据。  相似文献

The behaviour and personality of 102 pet rabbits and their interactions with their owners were assessed in their home environment. Information was obtained by interviews with the owner and by direct observation, and the owners were asked to describe the personality of their rabbit. A 10-minute assessment of the rabbit's behaviour in its normal environment was then carried out. Owners who were confident in handling their rabbit handled them more frequently and rabbits that were handled more frequently struggled less when they were being handled. Rabbits observed with a companion spent the largest proportion of their time engaged in social behaviour, and rabbits observed out of a hutch spent significantly more time grazing, hopping and playing. Owners used a wide range of adjectives to describe their rabbits' personalities with the most common term being ;friendly'.  相似文献

Staphylococcal enterotoxins (SEs) are emetic toxins causing food poisoning in humans, because of their biological activity and structural relatedness They have been classified as members of the pyrogenic exotoxin superantigen family Among them nine major antigenic types of emetic enterotoxins were recognized In recent years several newly detected SEs were also discriminated, but their occurrence and role in human and animal diseases are not fully understood Neverthless, evidences of their pathogenic role and broad distribution in staphylococcal strains cumulate Therefore their importance as potential risk factor for food safety becomes essential For this reason their properties, genetic determinants and supposed mechanisms of the pathogenic activity are discussed in respect of their potential hazard to human health.  相似文献
