Shizong County in Qujing City of southwest China's tobacco-producing Yunnan Province has installed 20,000 yellow sticky traps (boards) at tobacco fields in the seven industrial bases in the county to kill tobacco aphids, in efforts to further strengthen biological prevention and control of tobacco aphids in leaf tobacco production.

Normally, 20 days after transplantation of tobacco seedlings onto fields, there will occur tobacco aphids on tobacco crops. In May, the leaf tobacco stations under the seven industrial bases in Shizong County, in accordance with the requirement of Shizong County Tobacco Subcompany for installing one yellow sticky board in every five mu (every 0.33 hectare) of tobacco fields, placed orders for the production and supply of 20,000 30cm X 25cm medium-sized yellow sticky boards.

According to production technicians with Shizong County Tobacco Subcompany, the installation of the 20,000 yellow sticky boards at tobacco fields so far this year has generated favorable results of controlling tobacco aphids at lower costs, which is environment-friendly and harmless to natural enemy of tobacco aphids. With application of grease or machine oil on them, the boards can be used repeatedly. At peak periods, each yellow sticky board can trap and kill more than 300 tobacco aphids a day.

Over recent years, Shizong County has been successful in biological prevention and control of tobacco pests, with the use of Aphidius Gifuensis Ashmead to prevent and control tobacco aphids, the use of trichogramma to prevent and control oriental tobacco budworms, the use of sexual inductive agents to catch prodenia jitura, the use of polypeptide to protect tobacco crops, and the use of physical prevention and control means (solar energy pest control lights, yellow sticky boards, etc) in biological prevention and control of tobacco pests. With application of the technology for preventing and controlling tobacco aphids with Aphidius Gifuensis Ashmead as a breakthrough point, Shizong County has significantly extended the research and application of genetic diversity and biodiversity technologies to prevent and control tobacco pests, with "the use of insects to kill pests, use of germs to kill germs, the use of germs to kill pests, the use of insects to control the growth of grass, and the use of germs to control the growth of grass".
