改革开放 ２０ ａ来，农业和农村发生了巨大变化。农产品大幅度增长，基本上改变了“短缺经济的状况”，形成买方市场。农业和农村产业结构大调整，初步形成一、二、三产业共同发展的新局面。在这样的前提下，农业和农村将进入一个飞速发展时期，农作物病虫测报任重道远。１２
In the 20 years since the reform and opening up, tremendous changes have taken place in agriculture and rural areas.

Great adjustments were made in the industrial structure of agriculture and rural areas, initially forming a new situation in which the first, second and third industries will develop together. Under this premise, agriculture and rural areas will enter a period of rapid development, and there is still a long way to go before crop pests can be measured. 12
