%X The english grain aphid Macrosiphum aven is one of the most important agricultural pests, which results in serious wheat lost in China. The results from systematic observation from 2006 through 2008, demonstrated that meteorological factors such as wind and rain were essential for population development of english grain aphid. The gale during 6-7 grades (average wind speed was above 10m/s) significantly suppressed 65 percent of the population growth; A gust of wind (maximum wind speed was 18.8m/s) during filling stage blew the population number rapidly decreased and never recovered. The rainfall lasting 10 hours (daily rainfall was 32.2mm) led to 80 percent of decrease of aphid population, and population density did not recovery till 7 days late.
