Honeysuckle aphids:
1. Damage symptoms. They generally appear in early to mid-April. They mainly suck plant sap and spread viruses, causing leaves to turn yellow, curl and shrivel, and in severe cases can cause total crop failure. From April to June the infestation is heavier, and after the Start of Summer, especially on rainy days, it spreads faster. Adults and larvae pierce and suck leaf sap, causing leaves to curl and turn yellow. When honeysuckle is damaged at the bud stage, the buds become deformed; during the damage process they secrete honeydew, which affects leaf photosynthesis.
2. Control measures: (1) Remove weeds, and burn or bury dead branches and rotten leaves in a centralized way, which can also reduce the pest damage. (2) Before the plants sprout, spray once with lime sulfur, then spray once each at Qingming, Guyu and the Start of Summer, which can completely control aphids and also control many kinds of pests and diseases: (3) From late March to early April, when the leaves have spread out and aphids begin to appear, spray with 10% imidacloprid wettable powder at 1500-2000 times dilution, once every 5-7 days, for several consecutive sprays. The last application must be made 10-15 days before picking honeysuckle.
