Abstract
Studies on the external burrow structure of Nesokia indica were carried out in the central region of Punjab
province of Pakistan. As many as 130 active burrow systems located in non-crop sites and 287 in crop land
having three different soil type viz., clayey loam, sandy loam and saline soil were examined. On non-cropland
sites the burrows located in sandy loams averaged longer (2.6 m) than those of saline soils (1.8 m) and wider (1.1 m)
than those of clayey loams (0.8 m) at statistically significant levels. Irrespective of the soil types of non-crop
burrows, carried 4.4 mounds of average size of 2.1 x 0.98 m. Cropland burrow systems located in sugarcane
fields carried, on an average, 5.9 mounds measuring 3.5 m long and 2.0 m wide. Infield mounds measured larger
than those located in the field bunds and margins and embankment of water courses.
An average rice field burrow system had 4.7 mounds measuring 2.3 m long and 1.3 m wide. The mounds of
infield burrows averaged smaller than those located on field margins and bunds and embankments of water
courses.
