Analysis of Meteorological Conditions and the Forecast Study on the Wheat Aphid in Zhengzhou
Abstract：The characteristics of the occurrence of wheat aphid and the relationship between the wheat aphid and the environment factors as light, temperature, moisture etc were analyzed based on the data of wheat aphid and meteorological observatory from 1998 to 2009 in Zhengzhou combining with the biological characterization of wheat aphid. The main surface meteorological factors such as average tem- perature in early January, precipitation in early February, sunshine in late May and temp-related-precipi- ration in May that affect the occurrence and prevalence of wheat aphid in Zhengzhou were identified by u- sing the correlation coefficient method. Based above information, a prediction model for the occurrence of wheat aphid was established based on the forecast value of related meteorological factors. The prediction accuracy for former value was 95.0% correlated to the history record and 92.2% ＆ 90.0% correlated to the occurrence of wheat aphid in 2010 and 2011.
