Next, the editor of this site will introduce to everyone.A reader asks: What should I do if the privet has a starry longicorn infestation?Wei Songling from the Xi'an园林绿化 General Corporation answers:The privet starry longicorn that harms privet belongs to the Coleoptera, longicorn family, also known as the white-starred longicorn. The damaged privet trees are usually weak in growth, the stems are prone to breakage, and in severe cases, the entire plant may die.The starry longicorn can cause damage through both adults and larvae. When it harms privet, its larvae bore into the stem base or the root collar, gradually penetrating from the bark to the wood, creating various shapes of tunnels filled with feces or sawdust. During the peak period of damage, new sawdust and feces are often found outside the bored holes.Control methods:1. Horticultural control: Remove or promptly fell surrounding aging trees that are a source of pests; properly prune branches, especially paying attention to completely removing small suckers at the base of the plant to prevent adults from laying eggs there.2. Physical control: From August to September, after finding the larvae in the holes, insert a fine iron wire into the top of the fresh fecal hole and repeat several times to kill the larvae.3. Chemical control: During the egg stage or the early hatching stage of the larvae, you can spray 40% Chlopyrifos emulsion 2000 times dilution or 50% Phosphamid emulsion 2000 times dilution, etc., which have systemic properties. In mid-to-late August, when the larvae begin to bore into the stem and into the wood, you can use a fine iron wire hook to remove the fecal debris from the venting fecal hole and then insert a cotton ball soaked with 80% Dichlorvos emulsion or 40% Omite emulsion 10 to 30 times dilution into the hole to kill the larvae. Directly injecting 50% Fenvalerate emulsion or 50% Dichlorvos emulsion 200 times dilution into the hole is also possible, but the hole opening must be sealed with yellow mud.The above information introduces how to prevent and control the pest damage of the privet starry longicorn, hoping to bring a little help to your life!
