桃一点叶蝉在长江流域为桃的重要害虫,据在南京、徐州、洞庭东山等地调查,为害桃的叶蝉共有4种即:桃一点叶蝉Erythroneura sp.,小绿叶蝉Empoasca flavescens,大绿叶蝉Cicadella viridis及棉叶蝉Chlorita biguttula。以桃一点叶蝉为主。它的主要寄主是桃,其他尚有杏、李、中国樱桃、贴梗海棠、月季、苹果、梨等。桃一点叶蝉在南京一年发生四代,以第四代成虫在常绿树如龙柏、侧柏、柳杉、桧柏、马尾松、杨梅上越冬。至早春桃现蕾萌芽时,从越冬寄主上大部分直接迁飞到桃上,少量可到其他寄主上,4月以后都集中到桃上,直到晚秋开始作越冬之迁飞。至11月中下旬全部迁到常绿树上越冬。 室内药效测定结果:25%马拉松乳剂,30%E-605及25%DDT乳剂效果最好,41%敌百虫效果不好,效果最差的是10%γ666乳剂。两次田间防治试验结果与室内一致。在桃园内为避免经常使用DDT而引起螨类的大发生,可采用马拉松,E-605来代替或与DDT混合使用防治桃一点叶蝉及其他桃树害虫。
Peach little leafhopper in the Yangtze River Basin for peach pests, according to Nanjing, Xuzhou, Dongting Dongshan and other places surveyed peach leafhopper altogether there are 4 species: peach leafhopper Erythroneura sp., Green leafhopper Empoasca flavescens, large Cicadella viridis and Chlorita biguttula. Peach-based leafhopper. Its main host is peach, there are other apricot, plum, Chinese cherry, sticky Begonia, rose, apple, pear and so on. Peach a little leafhopper occurred in Nanjing four generations a year to the fourth generation of adults in evergreen trees such as cypress, arborvitae, cedar, cypress, massoniana, red bayberry on the winter. To early spring buds when budding budding, most of the direct transfer from the wintering host to the peach, a small amount to other hosts, after April are focused on the peach, until late autumn began to winter migratory. To late November all moved to evergreen trees wintering. Indoor efficacy test results: 25% marathon emulsion, 30% E-605 and 25% DDT emulsion best, 41% trichlorfon poor results, the worst effect is 10% γ666 emulsion. Two field control test results and indoor consistent. In order to avoid the frequent use of DDT in Taoyuan caused by the occurrence of mites, marathon, E-605 can be used instead of or in combination with the DDT pest control peach leafhoppers and other pests.
