Abstract

As the largest group of biological control agents, Parasitic Hymenoptera play important role in controlling pest outbreak in agricultural habitat. Unfortunately, there is lack of information about how these parasitoids occur in agricultural habitat related to condition of surrounding habitat and phenology of crop plant. The objective of this research was to study the effect of rice field surrounding habitat and age of rice plant on the diversity of Parasitic Hymenoptera. Research area was located in Carang Pulang Village, Dramaga, Bogor. We selected four blocks which represented different of habitat condition and age of rice plant. Each block was set six yellow pan traps (with minimum distance 20 meter) and one malaise trap. Sampling of insects were conducted weekly from 6 to 12 week after planting. From this research, we collected 1,833 individual of Hymenoptera (without ants) belong to 9 superfamilies, 23 families, and 216 species. Parasitic Hymenoptera was more abundant (96%) and species rich (84%) than Aculeata. Rice field surrounding habitat (block) and age of rice field significantly affect the diversity of Parasitic Hymenoptera. We found positively correlation between age of rice plant and species richness of Parasitic Hymenoptera.

Abstract

Agricultural intensification cause negative effect to insect diversity including beneficial insect such as natural enemies and pollinators. Habitat management through habitat heterogeneity is an alternative approach to protect insect diversity in agriculture area. In this study, we investigated the effect of habitat heterogeneity integrated with different age of crop plant in urban agricultural landscape to the ant diversity. The field research was conducted in agricultural area in Carang Pulang Village, Dramaga, Bogor. In around 6 ha area of rice field, grouped into four blocks which each block has different habitat condition and age of rice plant. In bunds of each block were put six pitfall traps with minimum distance 20 meter from each other. Ants were collected weekly from 6 until 12 weeks after planting to standardize the bunds condition. In total 22 species from 4 subfamilies of ants were recorded from this research. Iridomyrmex sp.01 and Odontoponera sp.01 are the common species which always found in each block and in different age of rice plant. There are no correlation between the distance of pitfall traps and similarity of ant species. In addition, habitat conditions surrounding rice field (block) significantly effect to the ant diversity. However, age of rice plant have no effect to the ant diversity.
