Two photographic missions per year are recommended to provide information on land-use and mosquito oviposition habitats. A winter mission, following a rain, will-provide a view of low areas within fields which may be obscured by summer vegetation. A summer mission will provide current land-use and crop distribution information and may show plant stress conditions due to excessive soil moisture. An aerial color infrared photographic survey with directed ground verification should result in a substantial savings in cost and increased efficiency in surveillance of mosquito producing habitats over ground survey techniques currently employed by mosquito control districts.
建议每年开展两次摄影任务，以提供土地利用和蚊虫产卵栖息地的信息。冬季降雨后执行的任务，将呈现出田地里低地的景象，这些低地在夏季可能会被植被遮挡。夏季任务将提供当前土地利用和作物分布信息，还可能显示因土壤水分过多导致的植物胁迫状况。与定向地面核查相结合的航空彩色红外摄影调查，相较于蚊虫防治区目前采用的地面调查技术，应能大幅节省成本并提高蚊虫滋生栖息地监测的效率。
