Abstract
Anura is an amphibian group of species with potential as natural pest predator. Data on food preferences and potential anuran species as pest control in horticultural lands at Doulu Village, Karo Regency, North Sumatera has not yet been reported. The aims of this study were to determine the type of food through stomach dissection and to evaluate the role of anuran species as a pest control by calculating percentage of insect pests as their preferred food. The results of this study found four species namely Duttaphrynus melanostictus, Phrynoidis juxtaspera, Fejervarya cancrivora and Hylarana erythraea. The results from stomach dissection found that 25 insect species belonging to 14 orders were preyed by the anuran species. Based on the percentage of insect pests as preferred food, species D. melanostictus was the most potential followed by H. erythraea, F. cancrivora and P. juxtaspera. It can be concluded that all anuran species found in this study acted as pest control in the habitat with different proportions.
