What medicine does crape myrtle use to treat fireflies?

To control fireflies, 52.25% Agrocybe aegerita emulsion 1000- 1200 times can be sprayed. This insecticide is also very effective in controlling locusts. To control locusts, 1500 times of 50% phoxim EC, 2000 times of fenvalerate or 2000 times of 2.5% cypermethrin can also be sprayed, which is suitable for the early use of locusts (grasshoppers) and has good insecticidal effect. Fenvalerate was stopped in Chinese cabbage before harvest 12 days. At the peak of the third generation damage (that is, whenever the new buds grow to 3-5 cm), chemical control is carried out. Available chemicals are: 1, 20% pyrethroid killing liquid 2000-3000 times; 2.800- 1000 times the solution of levoben or dichlorvos. Pick me.
