Melanotus cribricollis is one of the most important pest insects damaging bamboo shoots in South China, and there were not any reports about its monitoring techniques yet. The techniques of food bait trapping, light trapping and sex pheromone trapping of M. cribricollis larva or adults in fields were studied. The results showed that corn seed was the most effective attractant toward M. cribricollis larva, and in average, 2.38 wireworm were captured by each corn-seed bait, suggesting that corn seed could be used as food bait for wireworm monitoring. Observation on the seasonal activity of M. cribricollis wireworms indicated that there were two peaks, April to May and September to October. M. cribricollis adults swarming from the soil started from late April and ended at the end of August, and the peak was between the middle of June to the early July. These results provide a reference for effective control of bamboo wireworms.
