【摘要】：白纹伊蚊(Aedes albopletus)分布广泛,种群数量大,活动季节长, 嗜吸人血,是登革热、流行性乙型脑炎的媒介,因而被认为是重要的世界性卫生害虫。本文对白纹伊蚊形态特征、生物学特性、产卵习性、不同容器材料与水质对白纹伊蚊幼虫孽生情况的影响以及白纹伊蚊的季节消长等方面进行了研究,探索以白纹伊蚊幼虫为食料大量繁殖蚊虫捕食性天敌-褐尾库蚊(Culex fuscanus )的方法。白纹伊蚊形态学、生物学特性的研究,明确了白纹伊蚊不同虫期的形态特征、生活习性、季节发生规律以及该虫的生殖特征等。白纹伊蚊产卵习性的观察结果表明:白纹伊蚊在白天的产卵量大于晚上, 而且喜在黑色,粗糙的容器中靠近水面处产卵,容器中水位高低对其产卵量影响不明显。离地面距离越高,产卵量越少。不同材料容器和不同的水质对白纹伊蚊幼虫孳生情况有明显的影响,白纹伊蚊在不同材料容器与水质中均可孳生,但雨水和橡胶、竹筒容器最适合幼虫的生长繁殖。白纹伊蚊幼虫出现在3月中旬,成虫始见于3月下旬或4 月上旬,7至9月为发生高峰期,10月底至3月上旬不见成虫活动。褐尾库蚊(Culex fuscanus )是许多有害蚊虫的重要天敌。本文研究了褐尾库蚊不同虫期的形态特征、对猎物密度的捕食功能反应以及对自身密度的捕食功能反应,明确了褐尾库蚊的部分生物学特性,为褐尾库蚊的大量繁殖和有效利用提供了重要理论依据。捕食功能反应的研究表明:单个饲养的褐尾库蚊Ⅳ龄幼虫的日捕食量随白纹伊蚊密度的增大而增大:其日捕食量随自身密度的增大而减小。当给定不同种类的蚊子幼虫和不同龄期的白纹伊蚊幼虫时,褐尾库蚊Ⅳ龄幼虫喜食白纹伊蚊Ⅳ龄幼虫,对蛹的捕食量明显低于幼虫。猎物的大小、密度和活动能力影响了褐尾库蚊幼虫对猎物的选择性。
[Abstract]:Aedes albopletus (Aedes albopletus) is widely distributed, its population is large and its active season is long. Human blood aspiration, a vector of dengue fever and epidemic encephalitis B, is considered important World health pests This paper deals with the morphological characteristics, biological characteristics and spawning habits of Aedes albopictus. Effects of different Container Materials and Water quality on the larvae of Aedes albopictus and the Aedes albopictus In this paper, the seasonal variation was studied to explore the breeding of mosquitoes with Aedes albopictus larvae as feeding material. The method of Culex fuscanus, a predatory natural enemy. The morphological and biological characteristics of Aedes albopictus were studied. The different stages of Aedes albopictus were determined. Morphological characteristics, life habits, seasonal occurrence patterns and reproductive characteristics of the insect. White grain The results of observation on the spawning habits of Aedes albopictus showed that the number of eggs laid by Aedes albopictus in the daytime was larger than that in the night. And I like to lay eggs near the surface of the water in a black, rough container, where the water level is opposite to it. The effect of spawning quantity was not obvious. The higher the distance from the ground, the less eggs are laid. Containers of different materials and Different water quality has a significant effect on the breeding conditions of Aedes albopictus larvae. Material containers and water quality can breed, but Rain Water and rubber, bamboo container is the most suitable for larvae. Growth and reproduction. Aedes albopictus larvae appear in mid-March, and adults begin in late March or April From July to September, there was no adult activity from the end of October to the first ten days of March. Culex fuscanus is an important natural enemy of many harmful mosquitoes. Research in this paper The morphological characteristics of Culex pipiens browntail at different stages, the predation function response to prey density and the response of Some biological characteristics of Culex pipiens browntail were determined by the predation function of its own density. The mass propagation and effective utilization of Culex pipiens have provided important theoretical basis. Predatory functional response The results showed that the daily predation of the fourth instar larvae of Culex pipiens Brownieus was closely related to the density of Aedes albopictus. The daily predation decreases with the increase of density. When given a different When the larvae of mosquito species and Aedes albopictus of different ages are larvae, the fourth instar larvae of Culex pipiens browntail Aedes albopictus preying on pupae was significantly lower than that of larvae in the fourth instar larvae of Aedes albopictus. The size of the prey, Density and activity ability affect the selection of Culex pipiens Brown larvae to prey.
