Abstract

Predatory arthropods on cabbage terraces were studied by square flooding and by pitfall trapping in January 1992, following a transect through the Cordillera Region of Luzon, with decreasing numbers of insecticidal sprays per year. Predator numbers were sampled along this transect per 4 m2 and with 15 pitfall traps per site. The dry biomass of predators was also measured. The four sites studied were classified as two pairs, one with high input of insecticides and low predator numbers, low biomass and diversity, the other with low insecticidal input and high predator numbers, high biomass and diversity. The number of ant (Hymenoptera: Formicidae) genera per 15 pitfall traps increased along the transect, showing that ants might be used as indicators of the insecticidal intensity for growing vegetables in the Luzon Cordillera Region. Compared with Europe, the potential abundance and diversity of predators in the Philippines proved to be very high. The reasons for the large differences between sites concerning abundance and diversity of predators are discussed, together with conclusions drawn from the findings presented.
