摘　　要：对天津都市型现代农业核心区内病虫害进行了调查,以确定西花蓟马的种群变化、空间分布及番茄果实的受害情况。结果表明:西花蓟马成虫在温、湿度相对较高的环境条件下,种群密度高,较为活跃。西花蓟马在作物种植地块中部、靠墙等区域的植株中下部隐秘位置种群密度较高,为害严重,应该是灭虫时的主要防治部位。An investigation report was presented on population changes, spatial distribution of west flowered thrips Frankliniella oc- cidentalis （Pergande）and its damage on tomato fruits in Tianjin urban core area of modem agriculture. The results showed that high population density, more active FranklinieUa occidentalis（Pergande） adults occurred in relatively high temperature and humidity en- vironmental conditions. High density of Frankliniella occidentalis （Pergande） adults also occured in lower-middle parts of plants in the central locations of crop area or plants near the wall. So ,plants in these area locations and lower-middle part of plants were suggested to be main target sites when pest control was carried out.
