家蝇种质资源描述规范及其综合评价

A description criterion and comprehensive evaluation of housefly germplasm resources

家蝇Musca domesticaL.既是卫生害虫,又是重要的资源昆虫。根据家蝇的生物学性状特性以及利用价值,制定了家蝇种质资源描述规范和数据标准,为家蝇种质资源的评价提供了统一的标准和方法。在全国18省、市和自治区收集了54个家蝇地理种群,建立了国内最大的家蝇种质资源库,为家蝇优良品系的选育提供了资源。按照家蝇种质资源描述规范和数据标准对54个家蝇地理种群进行了标准化整理和数字化描述,描述和测定了家蝇种质资源的护照信息、标记信息、基本特征特性描述信息、图像信息、种质保存信息和共享方式共100多项指标,并对家蝇的产卵量、卵孵化率、老熟幼虫体重、幼虫发育历期等12个重要指标的数据进行了统计分析,发现家蝇各个地理种群的指标均有比较明显的差异,并利用DTOPSIS方法对上述家蝇种质资源进行了评价,其中优秀种群10个,良好种群33个,较差种群11个。

Housefly, Musca domestica, is not only a health pest but also an important resource insect. According to its biological characters and economic value, a description criterion and data standards for housefly were initiated, which provided its uniform data standards and measurement methods. Fifty four housefly geographic populations were collected all over the country, afterwards, the largest domestie housefly germplasm resource base was established which can be used for selecting outstanding housefly strains. According to above criteria, more than 100 indices of each of the 54 populations were descrihed and determined. The indices were divided into six types of information, such as passport message, label information, description information of basic characters, picture information, conservation information and ways for sharing resources. Of those, 12 indices, such as egg laying amount per female, hatching rate, mature larva weight, larva developmental time et al. , were statistically analyzed. It was shown that the indices of different geography populations were significantly different. Dynamic Technique for Order Preference by Similarity to Ideal Solution （DTOPSIS） method was used to evaluate housefly germplasm resources. According to results, 54 housefly populations were classified into 3 categories, 10 excellent geographic populations, 33 good geographic populations and 11 no-good geographic populations.
