Peach trees have high sugar content and many diseases and insect pests, and the peach tree Tianniu is one of the most harmful.
Peach trees generally live for about 30 years, but the lifespan of peach trees suffering from peach red neck is shortened to about 10 years, because it eats the trunk with larvae, weakens the tree, and in severe cases, it can cause the whole plant to die. It is the time when the Tianniu larvae plague the peach trunk, and experienced fruit growers can see at a glance that this trunk has been poisoned by the Tianniu larvae.
This year, the fruit farmer Lao Zhang led the whole family to go to the orchard to destroy the Tianniu, and to planed the ancestral grave of the peach tree Tianniu in one fell swoop. Sawing open a lesion, a huge celestial cow larvae squirmed out.
Sawing this trunk open again, it has been hollowed out by the larvae of the Celestial Bull, and it is heart-wrenching to think that the peach trees that have been planted for many years have been harmed by them like this.
The peach-necked celestial calf mainly harms the xylem, and the eggs are mostly produced in the crevices of the bark of the weak branches of the tree, and the larvae hatch and feed the phloem downwards. After the larvae regain their activity the following spring, they continue to feed downward from the cortex to the xylem surface, initially forming a short oval moth tunnel with a depression in the middle. So kill them at this time.
After June , the larvae moth from the middle of the moth tunnel into the xylem , which has an irregular moth. The larvae then feed from top to bottom and moth into curved, irregular holes in the trunk, some up to 50 cm long. Look at the sores that have been violated by this trunk.
These tianniu larvae are really more than one fat, and there is only one fate waiting for them, that is, the fire burns themselves, and who let them bring the peach tree into such a scourge, it can also be regarded as evil retribution.
