Abstract: A predator Chlaenius bioculatus Chaudoi of the fall armyworm, Spodoptera frugiperda, was found in the corn fields in Mangshi, Dehong Prefecture, Yunan. The biological control potential of C. bioculatus on S. frugiperda was assessed in laboratory using the 3rd instar larvae of C. bioculatus against the six instar larvae of S. frugiperda. Results show that the instantaneous attack rates were 1.1478, 1.3386, 1.3949, 1.2745, 1.3599, and 1.4227 for the 1st to 6th instar larvae of S. frugiperda, respectively. The handing time was 0.003592, 0.006836, 0.01365, 0.05536, 0.2895, and 0.4356 d, respectively. The maximum daily predation amount was 278.39, 146.30, 73.26, 18.06, 3.45, and 2.29, respectively. The results show that C. bioculatus larvae have a good control effect on S. frugiperda and have the potential to be used in biological control.

Key words: Chlaenius bioculatus, Spodoptera frugiperda, predation, biological control
