Occurrence of insect pests: Since the beginning of spring this year, the province has experienced less effective rainfall, drought in many places, and high temperature, resulting in early pest damage, and serious damage to thrips, leafhoppers and other pests. According to recent observations, thrips and other pests have a large number of overwintering insect populations. After the orchard is pruned, the orchard should be cleaned once, and then measures should be taken as soon as possible to reduce the number of overwintering insect populations, such as hanging yellow boards, blue boards, and insect traps.
