Abstract

Frogs that live in rice paddy habitats in Indonesia include Fejervarya limnocharis and Fejervarya cancrivora. The species of invertebrate eaten by Fejervarya cancrivora is still little known, so research needs to be done to analyze the species of invertebrate eaten by the frog. Samples of Fejervarya cancrivora frogs were randomly captured at two consecutive nights in the rice fields area of Ciomas sub-district, Bogor Regency and then 20% of the total catch was taken to be anesthetized, the rest was released back to the rice fields. The collection of invertebrates is taken from the gastrointestinal part of the toad. Identification of invertebrate species is carried out on some recognizable body remains of invertebrates. Based on the calculation of the Shannon-Winner Diversity Index, the species of invertebrate found in the female gastro intestinal Fejervarya cancrivora throughout the night has an index value of H* = 0.948, while the invertebrates in the gastrointestinal Fejervarya cancrivora male have an index value of H* = 0.845. Species of invertebrates found in gastrointestinal Fejervarya cancrivora include: Conocephalus longipenis, Panstenon nr. Collaris boucek, Pachydiplossis oryzae, Hydrella philippina, Haplothrips aculeatus, Microvelia douglasi (microvelia), Snellenius (Microplitis) manilae, Cnaphalocrosis medinalis, Oncomelania sp., Chilo supressalis. Euborellia stali (Dohrn), Gonatocerus sp., Dicladispa armigera, Oxyopes javanus, leftover leg crustaceans, Brachymeria lasus, and Nilaparvata lugens.
