Abstract
Orius tantillus (Motschulsky) and O. strigicollis (Poppius) are common on horticultural crops in Taiwan. These two species which are usually found on chrysanthemum and corn, prey on thrips, aphids, whiteflies, spider mites, and moth eggs. O. tantillus was found in higher densities than was O. strigicollis in Taiwan. Morphological structures of male genitalia are the major taxonomical characters used to separate these 2 species.
於1997年台灣園藝作物上調查發現三叉小黑花椿象Orius tantillus (Motschulsky)與南方小黑花椿象O. strigicollis (Poppius)，此兩種椿象常存在於同一寄主植物上，捕食薊馬、蚜蟲、粉蝨、葉蟎及蟲卵等，尤以菊花與玉米上最常見，而三叉小黑花椿象之數目又普遍較南方小黑花椿象為多。該兩種椿象主要依據雄蟲外生殖器之形狀構造而區辨。
