吉丁虫是以幼虫蛀食树干皮层,並导致树干流胶病发生的主要害虫之一。4月下旬为化蛹盛期,5月下旬为产卵盛期,6月中下旬为幼虫孵化盛期。树干皮层被害后,5月下旬至10月导致流胶病的发生,受害植株轻者树势减弱,落花落果,座果率低。重者树干腐朽,枝枯叶黄,甚至整株死亡。近年,各地果园发生尤为普遍,严重威协植株正常生长。这此,我 Jining bug is one of the major pests that larva eaten the trunk cortex and caused the gum disease in the trunk. In late April for the pupation peak, late May for the spawning peak, mid-late June larvae incubation period. After the trunk cortex was killed, late May to October led to the occurrence of melogenic disease, the victims of the light trees weaken, drop flowers, fruit set rate is low. Heavy trunk decay, dead leaves yellow, and even whole plant died. In recent years, the occurrence of orchards around the world is particularly common, serious normal plant growth. This, me
