The total number of trapped C.auricilius for 1 week at sugarcane or paddy field. The experiment was conducted from 4th Oct to 10th Oct (a) and from 3rd Nov to 9th Nov (b), 2017 at Baiyun experimental field, Guangzhou, Guangdong, China. a The number of trapped insects in paddy field when the rice was under seedling stage compared with the number in sugarcane field (the sugarcane was under stem elongation stage). b The number of trapped insects in paddy field when the rice was under tilling stage compared with the number in sugarcane field (the sugarcane was under stem elongation stage). The number of insects in one device was served as one replicate, and there are six trapping devices in each crop field. (t test; ***: P < 0.001,**:P < 0.01; *, P < 0.05; ns, not significant)
