中文摘要:

为了明确江苏省稻飞虱（白背飞虱Sogatella furcifera Horváth和褐飞虱Nilaparvata lugens Stal）在沉寂近10年后再次暴发的成因,通过分析江苏2020年白背飞虱和褐飞虱的田间调查及灯诱数据，并结合气象条件，研究了江苏省稻飞虱暴发的主要影响因素。结果表明：（1）2020年，江苏省白背飞虱虫源主要来自于江西中、北部，湖南东部以及湖北东部；褐飞虱虫源主要来自于安徽南部、浙江北部、本省南部以及江西省中北部。（2）江淮地区自6月中旬至7月下旬的超长降雨期有利于江苏省早期迁入虫源大量降落。（3）9月初，田间已存在大量褐飞虱短翅型成虫，适宜的秋季温度促使田间短翅型褐飞虱大量繁殖，导致后期田间褐飞虱大暴发。总而言之，超长降雨期有利于早期稻飞虱的迁入降落，而秋季的适宜温度引发短翅型成虫大量繁殖，是导致江苏省稻飞虱在沉寂近10年后再次暴发的主要因素。这些结果为稻飞虱暴发规律的阐明及可持续治理提供了理论依据和参考价值。

英文摘要:

The purpose of this article was to understand the cause of the outbreak of rice planthoppers (white-backed planthopper (WBPH) and brown planthopper (BPH)) in Jiangsu Province after nearly 10 years of silence. Based on the field survey and light trap data of WBPH and BPH in Jiangsu Province in 2020, and combined with meteorological data, the main influencing factors of rice planthopper outbreak in Jiangsu Province were studied. The results showed: (1) The sources of WBPH in Jiangsu Province were mainly central and northern Jiangxi, eastern Hunan and eastern Hubei in 2020. The sources of BPH were mainly from south Anhui, north Zhejiang, south of Jiangsu and north of Jiangxi Province in 2020. (2) The long rainfall period from mid-June to late July in Jianghuai region helped a large number of early migratory rice planthoppers landed in Jiangsu Province. (3) The suitable autumn temperature in September promoted the propagation of short-winged BPHs in the field, leading to the outbreak of BPH in the field. In conclusion, the main factors leading to the outbreak of rice planthopper in Jiangsu Province after nearly 10 years of silence were the long rainfall period, the suitable autumn temperature and the large reproduction of short-winged adults. These results provided theoretical basis and reference value for clarifying the outbreak regularity and sustainable management of rice planthoppers.
