Citrus giddings, also known as glutinous worms and poppers, are an important disease that harms citrus. In recent years, through the investigation of some citrus producing areas, it has been found that the phenomenon of citrus tree body death caused by the harm of gidding insects occurs from time to time, which restricts the development of the citrus industry. In order to curb the continued occurrence of this harmful symptom, Xiaobian will next analyze the harmful symptoms, occurrence rules and prevention and control measures of Giddingia, and then provide some suggestions for the development of China's citrus industry.
<h1>Harmful symptoms of citrus giddings</h1>
Adults mainly bite young leaves, and larvae mainly eat citrus branches and dry cortex, which is extremely harmful. Studies have pointed out that after citrus infestation, the cortex protrudes and cracks, and brown foamy gum flows out, which is also the main reason for inducing citrus flow gum disease. The data show that the gum disease caused by giddingia accounts for 60-80% of citrus gum disease, while the branches and dry bark burst and scorch along the worm path, and the whole plant dies when it is severe.
<h1>The occurrence of citrus giddings</h1>
In late March, the larvae moth into the xylem and begin to pupate, mid-to-late April for the pupal peak, about 25 days, early May is the peak of adult feathering, mid-term adults go out, in late May to early June adults begin to lay eggs wildly, July is the peak of egg hatching, these are the entire life cycle of Gidingia. The main cause of giddingia disease in citrus is due to the aging of the tree, the increase in cracks in the trunk and the weakening of the tree. At the same time, excessive air humidity is also an important factor in aggravating the harm of giddingworm.
<h1>Control measures for citrus giddingia diseases</h1>
Strengthen management
Fertilization, pruning and other pest control work in citrus orchards allows the plant to have a healthy growing environment, which in turn grows robustly and enhances the tree's resilience to stress.
Remove dead branches and dead trees
Dead branches and dead trees in the orchard should be removed in time, and measures such as burning or burying should be used to reduce the living space of gidding insects and reduce their harm.
Pharmaceutical control
Adult stage control: The resistance of adult insects that have just feathered out of the hole is relatively weak, and seizing this period for prevention and control can play a multiplier effect with half the effort. At this time, the method of poisoning can be used, specifically: spraying 25% cilvine wettable agent 400 times liquid on the branches.
Larval control: the prevention and control of brown foamy gelatinous substances in the pest of larvae is better. At this time, a mixture of 50% oxidized Lego emulsion plus a little kerosene can be applied to the harmful area to poison the newly moth-infused larvae.
