摘要
将无线传感器网络技术作为信息感知和传输的载体,设计和开发了橘小实蝇成虫发生量及环境因子协同监测系统,并在广州地区选择挂果期和成熟期柑橘园,开展了近6个月的橘小实蝇成虫发生量及其发生区域环境因子协同监测试验。结果表明：8月上旬至10月上旬,气温分布在22.5~36.5℃,且处于柑橘挂果期,橘小实蝇成虫发生量猛增并达到最大,周虫量516~893头;10月中旬至11月下旬,处于柑橘成熟期,天气干燥,气温分布在16.4~30.1℃,橘小实蝇成虫发生量开始呈波动性回落,周虫量108~293头;12月上旬至翌年1月中旬,降水量少,气温分布在10.5~27.5℃,由于缺乏维持营养的果实,橘小实蝇成虫数量很少,周虫量0~18头;对各环境因子进行主成分判别和因子主成分荷载分析表明,温光因素和降水对橘小实蝇成虫发生量的作用明显,其中,温光因素作用最大,空气和土壤温度是其主要因子,相应的成分荷载分别为0.960和0.961;降水作用次之,降水量和土壤含水量是其主要因子,相应的成分荷载分别为0.712和0.809。
Wireless sensor network technologies were used as a carrier of information acquisition and transmission, and a cooperative monitoring system for Bactrocera dorsalis （Hendel） and related environmental factors was designed and developed, and related monitoring experiments were taken almost six months from citrus＇ fruiting to mature periods in Guangzhou. Monitoring results showed that B. dorsalis occulTence numbers increasingly risen and reached maximum from the early part of August to the early part of October when the temperature were 22.5 ℃ to 36.5℃ during the fruiting period with B. dorsalisranging from 516 to 893 heads in per week; B. dorsalis occurrence numbers were shakily decreased from the middle of October to the latter part of November which was the citrus＇ mature period when the temperature gradually dropped from 30.1℃ to 16.4℃ with dry air, and B.dorsalis ranged from 108 to 293 heads in per week during this period; B. dorsalis occurrence numbers were sharply declined from the early part of December to the middle of January next year due to lack of fruit which provides nutrient maintenance, and B. dorsalis ranged from 0 to 18 heads in per week in this period. Statistics and payload analysis of principal component with environmental factors indicated that there were closely interaction among all factors, and temperature, light and the rainfall had significant effects on B. dorsalis occurrence, among which temperature and light showed the biggest effect with main factors being temperature and soil temperature with payload 0.960 and 0.961 respectively and the effect of the rainfall, whose main factors were rainfall and soil water content with corresponding payload 0.712 and 0.809 respectively, took the second place.
