摘要
Abstract
The monitoring data of Chilo suppressalis moths from 5 pest monitoring sites in the coastal rice area of Linhai,Zhejiang Province was used to clarify the evolutionary pattern of the population size of C.suppressalis and analyze the main factors contributing to its changes.The daily population size of C.suppressalis from 1990 to 2023 was studied.The results showed that the long-term cyclical movement of the C.suppressalis population was 22-23 years,and the evolutionary pattern in the recent 1.5 cycles was as follows:high quantity-medium quantity-low quantity-high quantity.Specifically,from 1990 to 1999,the occurrence duration of the C.suppressalis population lasted for 184 days with a daily average of 14.31 individuals per lamp;from 2000 to 2009,its occurrence duration lasted for 194 days with daily average of 10.67 individuals per lamp;from 2010 to 2019,its occurrence duration lasted for 201 days with a daily average of 7.05 individuals per lamp;and from 2020 to 2023,its occurrence duration lasted for 205 days with a daily average of 25.85 individuals per lamp.The main factors affecting the population size of C.suppressalis were the percentage of early rice,late rice,and single-season rice areas,as well as the average meteorological elements of the current year,including the average temperature,precipitation,and sunshine hours.There was a positive linear relationship for the single factor of the average winter temperature from December of the current year to February of the following year.The current C.suppressalis population is in the high-quantity recovery period of a new cycle,which is a period of high pest hazard.It is necessary to promptly carry out monitoring and controlling,and strive to improve the level of modernized pest control.关键词
