摘要

The bean bug, Riptortus pedestris, is one of the most economically salient pests of leguminous crops in Korea. It damages crops by sucking pods and fruits. We evaluated various types of rocket traps, along with wing colors and combinations of landing boards of various colors, in soybean field in South Korea. We developed a modified rocket trap intended to enhance the capture efficacy of stink bugs in the field. We evaluated (1) rocket traps with black, green, yellow, and white color stimuli and (2) traps with a wing and landing board. Our results showed that black wings with a black landing board attracted significantly more R. pedestris than other traps. Use of this improved trap combination would therefore enhance the monitor and capture of R. pedestris in various agroecological landscapes. The potency of these traps with a specific color, combination of features, and modifications to monitor R. pedestris are accurately discussed. Continued improvement to traps to address the demands of pest evolution and subtleties of cropping seasons are required.

點蜂緣蝽(Riptortus pedestris Thunberg)是韓國豆科作物中最具經濟重要性的害蟲之一。牠經由吸食果莢與果實而為害作物。本研究主要希望能開發一種改良的火箭型誘蟲器，藉以提高田間誘捕蝽項的效率。我們在韓國南部的大豆田中，評估了不同組合的誘蟲器，包括翼片(wing)與著陸板(landing board)的顏色及有無，對誘蟲效果之影響，結果顯示具黑色翼片及黑色著陸板的誘蟲器誘到的點蜂緣蝽數量顯著地比其他組合誘蟲器為多；因此，使用這種改良型誘蟲器將可強化在各種農業生態系中對點蜂緣蝽的監測和誘捕。在本研究，我們已對這些具特定顏色與結構組合的誘蟲器對點蜂緣蝽的誘捕效力進行詳細的討論；然而，本誘蟲器仍需配合害蟲演化上的差異與作物耕作季節的不同而持續進行改良，以達最佳誘蟲效力。
