How to control the pests of foraging pests on apple trees

Foraging pests on apple trees include A. striata, S. sylvestris, P. sylvestris, G. sinensis pests, Aromatic hibiscus moths, and Pear sylvestris. The characteristics of cockroach pests include: the species are relatively limited, and the geranium is the dominant species; the algebra is less every year; the larvae are overwintering in the scorpion; the eggs are produced in the groove, and the larvae directly drill the trunk; except for the worms In the early stage, there are no obvious symptoms, and there are many defecation holes; when the tree is weak, the damage is serious. There are several methods for controlling pests of dried cockroaches: combining pruning and removing insects; whitening the trunk to prevent spawning of A. serrata and P. sylvestris, white formula: 10 parts of quicklime, 1 to 2 parts of salt, sulfur 1 part of powder (or 3 to 4 parts of stone sulphur mixture slag) and 40 parts of water; using the characteristics of feeding young leaves and tender branches to supplement nutrition before laying eggs, it can spray 80% of dichlorvos on the canopy during adult stage. 90% crystal trichlorfon, etc.; injection in the pupil: use a syringe to inject 80% of dichlorvos into the pupil, and block the orifice with mud. Fill the pupil with 1/4 to 1/6 of the aluminum phosphide tablet, and then tighten the orifice with wet mud. One end of the aluminum phosphide poisoning tape is inserted into the pupil, one per hole, and the depth is 7 to 1Ocm. The method for making the poisonous label is as follows: first add 20 parts of bone glue to 40 parts of water, heat it by water to make a glue, and then add 2 parts of the glue, add 1 part of zinc phosphide, 1 part of oxalic acid, and stir evenly. Instant zinc phosphide and oxalic acid glue. Then take 7 ~ 10cm long diameter 0.1 ~ 0.2cm wooden sign, one end of bismuth phosphide glue, dry, and then add a layer of oxalic acid glue, dry.
