红脂大小蠹在吕梁地区主要以老熟幼虫、成虫、少量蛹在油松根部越冬 ,1年发生 1代。主要以幼虫 ,其次是成虫取食韧皮部后 ,切断树木水分和养分通道而致树木死亡。越冬成虫于 5月中旬进入扬飞盛期 ,第一代成虫于 8月中旬进入扬飞盛期。以上两个阶段成虫钻出树皮在野外寻求新的寄主时 ,是防治的最佳时期。经试验 ,在树木基部 10～ 16cm周围的土层内挖 4个孔 ,孔深 2 0～30cm ,每孔内放 1～ 2片磷化铝片剂 ,用土掩埋踏实可熏杀根部害虫。
Red-winged beetles in Luliang mainly larvae, adults, a small amount of pupae overwintered in the root of Pinus tabulaeformis, 1 generation occurred 1 year. Mainly to larvae, followed by adult feeding phloem, cut off trees and nutrient channels and cause death of trees. The overwintering adult worms entered the Yangsheng peak in mid-May. The first generation of adults entered the Yangsheng peak in mid-August. The above two stages of adult bark drilling in the wild to find a new host, is the best time to control. After the test, 4 holes were drilled in the soil layer around 10-16 cm of the base of the tree, with a hole depth of 20-30 cm. One or two pieces of aluminum phosphide tablets were placed in each hole, and the soil was buried with soil to smoothen root pests.
