广西作为全国甘蔗种植面积和蔗糖的重要生产基地,自1992年以来种植面积及产糖量居全国第一,目前全区50%县(市)种植甘蔗,种植面积大约达1600万亩,占全国的50%。甘蔗蓟马是广西蔗区主要害虫之一,分布于全区蔗区。由于该虫具有发生早、数量多、个体小、发生速度快、危害时间长,世代重叠、易传播扩散,危害部位隐蔽等特点,往往不易被种植户所发现和重视,加之近几年来甘蔗生产发展很快,连片面积大,连作突出,管理粗放,为甘蔗蓟马的越冬繁殖及发生创造了较好的条件,导致甘蔗蓟马危害逐年加重,各蔗区蓟马危害呈上升趋
As an important production base of sugarcane acreage and sucrose in the country, Guangxi has the largest acreage and sugar production since 1992. Currently, 50% of the counties (cities) in the region planted sugarcane, with an acreage of about 16 million mu Of the 50%. Sugarcane thrips is one of the major pests in Guangxi sugarcane, located in the whole area of sugarcane. Because of its characteristics such as early occurrence, large quantity, small individual, rapid occurrence, long time of harm, generation overlap, spread easily, concealed parts of hidden danger, etc., it is often not easily found and valued by growers. In addition, in recent years, sugarcane production The rapid development, contiguous area, even as a prominent, extensive management, for the overwintering reproduction and occurrence of sugarcane thrips to create better conditions, resulting in increased risk of sugar cane thrips increased year by year, the cane thrips increased the risk of harm
