How to control longhorn beetle larvae? Detailed explanation of control methods and technical key points
How to control longhorn beetle larvae? Longhorn beetle larvae cause very severe damage to fruit trees. How should they be controlled? Please provide methods. Damage caused by longhorn beetles: larvae of the bark-girdling longhorn beetle girdle the bark (gnawing the green surface layer of the trunk); larvae of the Miezi ridge tiger longhorn beetle damage branches and trunks, boring the xylem into crisscrossing tunnels and boring toward the center of the stem, damaging the pith, then boring downward to damage the roots. This seriously affects water transport, causing weakened tree growth, withered yellow branches and leaves, and symptoms of fertilizer and water deficiency.
