Abstract

Rodent species have been known as the major pest in the agricultural sector leading to economic losses. They are also identified as the vector for several rodent -borne zoonotic diseases. However, a specific study on observing their diversity in households closed to lowland irrigated agroecosystems that correspond to disease distribution’s role is limited. To address this issue, a field study was performed during the 2019 -2020 cropping season in two sites (Yogyakarta and West Java) which were categorized as the rice production centers. Trapping was conducted consecutively for 13-30 days using 65-75 snap traps. Roasted coconut and salty fish were used to attract rodents. In West Java, 3 rodent species (Rattus argentiventer,Rattus tanezumi,Bandicota indica) and insectivore small mammal (Suncus murinus) were discovered from 1,950 trap nights. Meanwhile, the setting of 900 trap nights in Yogyakarta indicated less diverse rodents with only one species (Rattus tanezumi) and the same insectivore discovered. All captured animals were dissected and observed for the endoparasites. We obtained two potent species of parasites (Taenia taeniaeformisandCapillaria hepatica), which can be transmitted by rodents to the local people if they do not apply a proper health practice.

Highlights

Rodents constitute the largest group of mammals comprising 2,000-2,700 species distributed worldwide
Three species of rodent (R. argentiventer, R. tanezumi, and B. indica) and one small mammal categorized as insectivore (S. murinus) were discovered
Animals trapped from Yogyakarta consisted of one species of rodent (R. tanezumi) only and insectivore (S. murinus), the same species as we retrieved from West Java (Table 1)

Summary

Introduction

Rodents constitute the largest group of mammals comprising 2,000-2,700 species distributed worldwide. The majority of rodent species are small in body size with strong adaptation skills. They have continuously growing incisors, which leads to the frequent destructive habit of gnawing some objects [4] [3]. Previous studies highlight that rodent species hold such benefits through ecological, scientific, social, and/or economic significances. They influence plant progression by playing an important role in distributing seeds, spores, and reprocess nutrients [6]. Damage can be remarkably critical when rodent outbreaks occur, with acute losses often greater than 30% [15]
