气候变化背景下玉米棉铃虫消长动态预测及影响因素研究
Study on the factors affecting corn’s Helicoverpa armigera dynamic prediction under the background of climate change
摘要
Abstract
The helicoverpa armigera investigation data from the Center of Plant Protection Station of Wuwei and me -teorological data during 1953 to 2010 years from Wuwei Bureau of Meteorology were used .We established population growth model of helicoverpa armigera and meteorological forecast model ,by which the characteristics and effects of cli-mate warming were analyzed .The results showed that the accumulated egg number per 100 plants’ growth followed a typ-ical “S” curve .The rapid growth period was in late July to early August (the corn silking stage) .The prediction model had a prediction accuracy rate of 78% ~ 89% .The impact of climate change on the occurrence and development of heli-coverpa armigera were revealed .And the increased temperature was favorable for helicoverpa armigera population growth and reproduction .关键词
