Abstract： The effectiveness of nine kinds of pesticides for controlling the sycamore lace bug Corythucha ciliate (Say), a new invasive insect species which heavily damages Platanus spp. and other horticultural plants, was tested in the laboratory and the field. The two most effective pesticides, 1.2% matrine plus nicotine EC 2 000 and 2.5% bifenthrin EC 3 000, achieved control efficiencies > 95% 29 days after application. These two pesticides were environmentally friendly, did not damage crop plants and are therefore suitable for widespread use.
