　　Abstract Stink bugs are recognized as pests of several economically important crops, including cotton, soybean and a variety of tree fruits. The Cyranose 320 was used for the classified investigation of stink bug. Stink bugs including males and females of the southern green stink bugs, Nezara viridula, were collected from crop fields around College Station, TX. Results show that the released chemicals and chemical intensity are both critical factors, which determine the rate that the Cyranose 320 correctly identified the stink bugs. The Cyranose 320 shows significant potential in identifying stink bugs, and can classify stink bug samples by species and gender.
　　臭蟲(chóng)被認(rèn)為是幾種重要的經(jīng)濟(jì)作物的害蟲(chóng)，包括棉花、大豆和各種樹(shù)果實(shí)。以Cyranose 320便攜式電子鼻為研究對(duì)象，對(duì)臭蟲(chóng)進(jìn)行了分類調(diào)查。從德克薩斯州大學(xué)站周?chē)霓r(nóng)田中采集了南部綠色臭蟲(chóng)Nezara viridula的雌雄臭蟲(chóng)，結(jié)果表明，釋放出的化學(xué)物質(zhì)和化學(xué)強(qiáng)度都是決定cyranose 320正確率的關(guān)鍵因素。發(fā)現(xiàn)了臭蟲(chóng)。Cyranose320在識(shí)別臭蟲(chóng)方面顯示出巨大的潛力，可以根據(jù)臭蟲(chóng)的種類和性別對(duì)臭蟲(chóng)樣品進(jìn)行分類。
