Abstract:

To clarify the species composition and annual dynamics of dominant population of underground pests which caused serious damage to wheat and maize in Linfen, Shanxi, we investigated the populations of underground pests in two crops (wheat and maize) a year farmland by the method of black light trapping, and analyzed the trapped adults by the methods of indoor identification, data analysis, and literature retrieval. The results showed that: 7 species were the dominant populations, such as Anomala corpulenta and Metabolus tumidifrons; and the occurrence quantity and period of different dominant populations were different, their phototactic responses to black light were also different; the occurrence period of the absolute dominant population (Anomala corpulentai) adults was relatively concentrated from late June to mid-july, and A. corpulentai was highly sensitive to black light and could be monitored and controlled by black light trapping.

Key words: underground pests, black light trapping, dominant species, population dynamics
