一种现场防控蚊虫装置的研究

Introduction of a new facility for mosquito control research in field

一种好的蚊虫防治方法需要在现场确认效果后,才能得到推广。现场模拟系统封闭设施根据现场环境特点设计,具有在室内操作现场试验的优点,它安全有效,并能达到温控的效果。现场模拟系统的实验室和蚊笼装置模拟住户房屋和庭院结构设计,利于蚊虫孳生。现场模拟系统由1个二级检疫昆虫饲养实验室组成,该实验室有3个恒温室,实验室紧连着2个二级检验检疫局蚊笼,蚊笼用于释放蚊虫。每个蚊笼内部有木屋和庭院。自控式空调系统能将蚊笼环境温湿度分别控制在1℃和5%范围内波动。蚊笼中的蚊虫成活率高,雌蚊成活率更高。

Novel vector control strategies require validation in the field before they can be widely accepted. Semi- field system（SFS） containment facilities are an intermediate step between laboratory and field trials that offer a safe, controlled environment that replicates field conditions, a SFS laboratory and cage complex simulates an urban house and yard which is the primary habitat for mosquito. The SFS consists of a Quarantine Insectary Level-2 （ QIC-2 ） laboratory, containing 3 constant temperature rooms, that is connected to two QIS-2 cages for housing released mosquitoes. Each cage contains the understory of a timber house and associated yard. An automated air conditioning system keeps temperature and humidity to within 1 ℃ and 5% RH of ambient conditions, respectively. Survival of released mosquito is high, especially for females.
