与北方地区不同,南方西甜瓜上除了蚜虫、粉虱、蓟马和害螨类外,还常发生有瓜绢螟、黄守瓜和实蝇类等。南方地区温度高,害虫可周年为害,生产上更应该注重早期识别与防控,发挥害虫全程绿色防控技术的作用。2015年我国西甜瓜播种面积232.2万hm~2(3 480万亩),总产量9 240万t,居世界之首(王娟娟,2017)。海南、福建、江西、云南等地是冬春季西甜瓜的主要供应产区,海南还因其独特的气候条件成为西甜瓜反季节繁育基地。南方温度高,害虫发生为害更早,部分地区可周年发生,害虫防控
And the northern region is different from the southern melon in addition to aphids, whiteflies, thrips and pests mites, but also often occur with the Ginger silkworm, yellow Shougua and real flies and so on. In the south, the temperature is high and the pests can be damaged on an annual basis. More attention should be paid to early identification and prevention and control in production so as to play the role of the pest’s green prevention and control technology. In 2015, the sown area of melon in China was 232.2 million hm 2 (34.8 million mu), with a total output of 92.4 million tons, ranking first in the world (Wangjuanjuan, 2017). Hainan, Fujian, Jiangxi, Yunnan and other places are the major supply areas for winter and spring melon. Hainan has also become the base of western melon season-breeding due to its unique climatic conditions. South high temperature, pests occurred earlier damage, in some areas may occur annually, pest control
