What are the control methods for the Schisandra leaf-roller caterpillar?

Control of the Schisandra leaf-roller caterpillar:

It occurs from July to August. The larvae are white at first and later turn green. Young larvae chew the leaf mesophyll, and after the 3rd instar they roll the leaves and feed inside, affecting fruit development.  

Control methods:  

① Before the larvae roll the leaves, spray with 80% trichlorfon at 1000-1500 times dilution.  

② After the leaves are rolled, spray with 40% dimethoate emulsifiable concentrate at 1000-1500 times dilution.  

③ Spray with 50% phoxim at 1500 times dilution.  

④ Spray with 50% phosphamidon emulsifiable concentrate at 2000 times dilution.  

⑤ Before and after the larvae roll the leaves, they can also be caught by hand.
