| 中文摘要: |
| 为掌握柑桔木虱越冬习性，2014—2022年监测了赣南地区柑桔木虱越冬情况，结果表明，柑桔木虱在江西赣州主要以成虫形态在芸香科植物或杂草上较温暖处越冬，冬季温暖的年份（日均温高于6.6℃），部分高龄若虫可以越冬至次年1月下旬羽化。冬季成虫主要在芸香科植物上越冬，存活极限为245d，也可在小篷草、女贞、龙葵、二面针上存活，存货极限分别为22d、50d、52d、106d；长时间的低温天气（-4℃，持续4d）会造成越冬成虫大量死亡，同样气候条件下，田间小气候对成虫的存活率也有较大影响。 |
| 英文摘要: |
| In order to master the overwintering habits of Diaphorina citri Kuwayama , the overwintering situation of Diaphorina citri Kuwayama in Gannan area was monitored from 2014 to 2022. The results showed that in Ganzhou, Jiangxi Province, citrus Psylla mainly overwintered in the form of adults in warmer places on Rutaceae plants or weeds. In warm winter years (the daily average temperature is higher than 6.6 ℃), some old nymphs can overwinter and emerge in late January of the following year. In winter, adults mainly overwinter on Rutaceae plants, with a survival limit of 245 days. They can also survive on small canopy grass, Ligustrum lucidum, Solanum nigrum and two-sided needle, with a storage limit of 22d, 50D, 52d and 106d respectively; A long period of low temperature (- 4 ℃, lasting for 4 days) will cause a large number of overwintering adults to die. Under the same climate conditions, the field microclimate also has a great impact on the survival rate of adults. |
