Dynamic Research on Geometridae in Songhua Lake Area in Different Seasons
A systemic investigation into the geometridae insects in Songhua Lake area was carried out. The results showed that the geometridae insects in Songhua Lake area changed with the seasons obviously. The number of their communities was largest in June; the dominance of major geometridae insects varies with the seasons significantly, namely, the dominant species were different in different seasons; the diversity, evenness and dominant concentration indexes changed significantly in different seasons, that is, all of them were at lower levels in May and September, highest in June and the changes of them were smooth in July and August. This study should be conducive to the effective control of the damage by the pest and lay a solid foundation for better protecting the forest resources of Songhua Lake area.
