Fat, the heart of the tree is empty

It can be seen that the Tianniu family from small to large is not a good thing, the larvae drill the heart of the tree, the tunnel, the adult bites the branch, when the larva drills into the heart of the tree, if it does not go to the treatment, it will drill the heart of the tree, the whole tree will die, because in the heart of the tree, thus increasing the difficulty of prevention, novices may not be able to find, when found after the tree has not been saved.

So what about this prevention? Quite simply, prevention and control combine:

The cattle worm begins to be active in March when the weather warms up, pupates begin in May, adult worms appear in June, bloom in June-July, and lay eggs in mid-June, with an egg period of 7-15 days, laying eggs on the branches, and the spawning trough will find fresh worm droppings and wood ash discharged from the fecal opening.

Treatment is mainly based on three aspects:

1, adult insects: before spawning to kill the adult insects, you can use gastric killing, touch killing pesticides

2. Insect eggs: after dilution with pesticides, spray through the egg-laying trough to kill the eggs inside.

3, larvae: diluted with a touch killing, fumigation type of pesticide, from the fecal mouth with injection, and then with mud to seal the hole, so that can effectively kill the Tianniu larvae, is not very simple.
