Judul: Komunitas Staphylinidae (Coleoptera) di Persawahan Sekitar Bogor dan Struktur Histologi Paederus fuscipes Curt.
Abstrak: The insect is an important component in the rice field ecosystem. One of the groups of insects in rice field ecosystems is family Staphylinidae. Staphylinids are charactarized by short elytra, so it does not cover the all abdominal segments. This research aimed to study community of staphylinids in some rice field in Bogor. Histological structures of Paederus fuscipes were studied. Collections of the beetles were done by road sampling method. The weathers, i.e temperature, humidity, and light intensity were measured during collections of staphylinids. Histological structure of P. fuscipes were observed based on paraffin method. Staphylinids collected in the three locations of rice field were Paederus fuscipes, Cryptobium abdominale, and Stenus sp. Staphylinids dominant in rice fields was P. fuscipes. An histological structure of P. fuscipes identified were the stomach, Malpighian tubule, rectum and anus.

Abstrak: Staphylinid beetles (order Coleoptera) are characterized by elongated and slender body shape, short elytra that covered some segments of the abdomen, and body usually shiny black, brown, or yellow-brown. In the paddy field ecosystem, these beetles are known as predator. This research aimed to measure the diversity and abundance of staphylinid beetles in the paddy field at some areas in Bogor. The research also studied the hemolymph structure of Paederus fuscipes. Collections of beetle were done by using road sampling method in some paddy fields. Observations of hemolymph structure were done by making a blood smear. Staphylinid beetles found in six paddy fields in Bogor were Paederus fuscipes (subfamily Paederinae), Stenus sp. (subfamily Steninae), Hypostenus arachnoides (subfamily Steninae), and Astenus lombokianus (subfamily Paederinae). Diversity of staphylinid species in paddy fields is low. The most dominant species staphylinid at the paddy fields was P. fuscipes. Hemocytes type found in the hemolymph of P. fuscipes beetles were prohemocyte, plasmatocyte, adipohemocyte, and cystocyte.
