Control method: When adults emerge, infuse flower soil with 80% trichlorfon 1000 times solution. During the peak spawning period, spray 600 times of 50% phoxim and sulfur emulsifiable solution once every 7 to 10 days; cut off and burn insect branches found; if there are insect holes, insert 80% dichlorvos solution soaked cotton wool, seal with soil, poison larvae. Inchworm larvae nibble on leaves after anthesis, causing yield reduction. Control method: After spring, dig soil within 1 meter around the plant to kill pupae.
