How to control the spring flower carpenter moth? A detailed guide to practical methods
Spring flower carpenter moth: the larvae bore and feed inside branches and trunks, commonly seen on peach, plum and cherry blossoms; in severe cases they can bore through and snap 2- to 3-year-old large branches, affecting the tree's shape.
Control methods: pay attention to observation at ordinary times. When there are borer holes on branches or trunks and small granular frass is being expelled from the holes, you can use an iron wire to dig out the insect from the hole along the tunnel, or cut off the branch to kill the pest. The insect itself is reddish-brown, with hairs on its head and on each segment of its body, clearly different from the milky white of longhorn beetles. This method is also used to control longhorn beetles. You can also use 80% dichlorvos emulsifiable concentrate at 150 times dilution, inject it into the tunnel with a syringe through the frass-expelling opening, then plug the tunnel with wet mud to kill the pest.
