小黑棕鳃金龟(Apogonia chinensis Moser),在我们铁岭地区分布广,数量大,在黄土丘陵地区占蛴螬总量90%以上,一般豆茬地平均每平方米有虫3—5头,多者达200头以上。因此,小黑棕鳃金龟是铁岭地区蛴螬种类中优势种之一(另一个优势种为东北大黑鳃金龟)。 当地群众通称的高粱“黄病”、是铁岭地区严重病害之一。这种病害主要是蛴螬为害所致;在部分地区榆四条绵蚜,麦根蝽象等也能引起发病。但小黑棕鳃金龟幼虫为害, Apogonia chinensis Moser is widely distributed and abundant in our Tieling area, accounting for more than 90% of the total snakeheads in the Loess Hilly region, with an average of 3-5 heads per square meter in the general stubble field, Up to 200 or more. As a result, Pinctada fulvus was one of the dominant species in the Tuna range in Tieling (another dominant species was the Black-lipped beetle in Northeast China). The local people called the sorghum “yellow disease”, is one of the serious diseases in Tieling. This disease is mainly caused by catfish damage; in some areas four cotton aphids, wheat root stink bug can also cause disease. But the small brown beetle larva damage,
