Overview

The lesser bandicoot rat (Bandicota bengalensis) is a large, burrowing rodent native to South Asia. It belongs to the genus Bandicota rather than the true rats of the genus Rattus, and is commonly encountered near human habitation and cultivated land. The species is notable for its stocky build, short tail relative to body length, and habit of digging extensive burrow systems.

Identification and physical characteristics

Adult lesser bandicoot rats have a heavyset body with coarse fur that is typically dark brown or grizzled on the back and paler, often greyish, on the belly. Body length is commonly in the range of two to three dozen centimetres, with the tail noticeably shorter than the head-and-body measurement; total lengths of individual animals may approach those reported in the field literature. The skull and dentition are robust, adapted for gnawing roots, tubers and tough plant material.

Distribution and habitat

Bandicota bengalensis occurs across much of mainland South Asia, inhabiting agricultural fields, gardens, grasslands and peri-urban areas. It readily exploits environments altered by people, where food and burrowing sites are available. Populations may be especially dense in irrigated cereal-growing regions where the combination of shelter and abundant grain provides favourable conditions.

Behaviour, diet and reproduction

This species is primarily nocturnal and crepuscular, although it can be active by day in undisturbed locations. It constructs complex burrows with multiple entrances and stores food underground. Diet is mainly plant-based (seeds, roots, stems, cultivated cereals) but opportunistic feeding on invertebrates and household refuse has been recorded. Reproduction is relatively rapid: females can breed through much of the year in favourable climates, producing several litters containing multiple young over a breeding season.

Interactions with people and significance

Lesser bandicoot rats are often regarded as agricultural pests because they feed on and damage standing crops, stored grain and garden plants. Their burrowing can undermine irrigation channels and structures, and their presence near homes raises concerns about contamination of food and potential transmission of parasites and pathogens. Control measures used by farmers combine habitat management, exclusion, trapping and, where appropriate and regulated, chemical control; integrated approaches that reduce food availability and block burrow access are commonly recommended.

Taxonomy, similar species and notable facts

Within the genus Bandicota, the lesser bandicoot rat is distinguished from the larger greater bandicoot rat (Bandicota indica) by its overall smaller size and proportions. Although called a "rat," it is taxonomically separate from the common Rattus species. The animal can make loud vocalisations when handled or threatened; observers have reported pig-like grunts among its range of sounds. Like many commensal rodents, it may host ectoparasites and internal parasites, so basic hygiene and careful handling are advised.
