Three locusts that harm apricot trees

There are three kinds of aphids that harm apricot trees: peach aphid, peach aphid, and peach aphid.

Their habits:

All three aphids wintered at the axillary buds of the apricot. The peach oysters began to be egg-shaped in March of the following year. The oysters reached their peak when the oysters were ready to be opened, and they were nearly finished after the flowers were opened. After leaf development, adult or small nymphs clustered behind the leaves and endangered and parthenogenetically propagated. In May, the damage was severe and the reproduction was fastest. However, after mid-May, wings of female embryos migrated to summer hosts such as cruciferous vegetable tobacco and flew back to apricot trees in late autumn.

The occurrence time of Peachflies is slightly later than Peach Peaches, others are similar to Peach Peaches.

Peach tumors occur in May and are now endangered. They occur from June to July. After that, they produce winged females and move to summer hosts such as wormwood. In October, she moved back to the almond tree.

Control methods:

After the apricot sprouts, spray 10% of the fleas 3000--5000 times to control peach aphid or whitefly after flowering or after flowering; in late April, spray 10% of the fleas to control peach aphid. In the great period of occurrence, spray 2000-3000 times the net again.

Long Range LiDAR Radar

Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.

Highlights:

> Measurement frequency: 400 Hz (Max 60m 3000Hz)
> Long range: 200m
> High temperatures: -10~+50℃
> UART output
> Connector design: easy to use
