The use of Kruskal-Wallis test indicates significant difference in the abundance and species richness per bait method in pitfall trapping.Ĭomparative efficiency of different collection methods of carabid beetles in Eastern Visayas, PhilippinesĪdis J. Likewise, fermented fish with vinegar showed the highest diversity (5.168), high equitability, highest dominance (2.984) and richness (40) compared to other baits used in the pitfall trapping. Fermented fish with vinegar garnered the highest number of indivuals at 1,894 (56.94%) of the total catch. A total of 3,326 carabid individuals belonging to 40 species were collected. The use of fermented fish with vinegar has never been used before by any author and is a new bait method discovered by the researcher during the study. The study used four different baits in the pitfall trapping, namely: vinegar, mixture of ketchup and vinegar, fermented fish with vinegar, and ground meat. Using Kruskal-Wallis test, indicated a no significant difference in the abundance and species richness per method of collection, i.e. Among these, 3,326 individuals, representing 41 species, were caught in pitfall traps, while the remaining 4,518 individuals, representing 49 species, were caught using handpicking or ground searching. The total number of individuals caught using the two methods was 7844 carabids belonging to 25 genera and 49 species.

Two different methods (pitfall traps and hand picking) were used to sample carabid beetles in six forests of Eastern Visayas, namely: Lake Danao, Mt.
