Abstract

The effect of Trichoderma applied to cabbage farms on the abundance of collembolans was assessed, this being the first study conducted on this subject. Emphasis was given on collembolans mainly because they include fungivores and share same ecological requirements with Trichoderma. Field experiments were conducted in Barangay Mamala 1 (Site 1) and Sampaloc 1 (Site 2) in Sariaya, Quezon to determine possible differences in abundance between Trichoderma-enhanced and conventional cabbage plots. Soil samples were collected at 20,40 and 60 days after planting (DAP) from both sites and ran through Berlese-Tullgren funnel to extract arthropods, five collembolan species were identified. Result showed that both sites, the total abundance of arthropods was higher in Trichoderma-treated (Site 1: 4926, Site 2: 2336) than in the conventional plots (Site 1: 2502, Site 2: 926). However, results varied between sampling periods depending on the prevailing physical conditions, thus showing no significant difference for collembolans. Therefore, Trichoderma may enhance the population of collembolans given optimal conditions but beneficial effects in maintaining such populations may be diminished under suboptimal conditions.
