Abstract:
Meteorological condition is the key factor which affects the emergence period of locust migratoria manilensis.It is necessary for preventing and curing insect pest to establish meteorological forecast model of the emergence period.Through the analysis of observation data of meteorological of locust migratoria manilensis in different ecological region in Hebei and data in its corresponding period using compound analysis,the critical factor affecting the growth period is selected.Forecast model of the emergence period of locust migratoria manilensis in Hebei is established by stepwise regression method.Through the examination,the forecast was consistent with the real condition in 2004 and 2005 respectively,and the error is no more than 4 d.The results can be turned into operation.
Key words:
