Hibernative Behavior of Scorpions in District Sheikhupura Punjab, Pakistan

Abstract

Background: In the current study, the scorpion’s hibernative behavior was observed both in field and laboratory. The study  was conducted in Sheikhupura District, Punjab, Pakistan.  Methods: For scorpion collection, different active and passive methods were adopted. The study period was two years (2021 2022). Live observations were made with ultraviolet light at  night, while daytime observations were made by rolling bricks and digging muddy houses in rural areas. The Scorpions were also observed at the Department of Zoology, University of Education, Lahore Faisalabad Campus. Scorpions were maintained in a controlled environment at a temperature range of 25-30°C. The relative humidity was maintained at 60-70%. The scorpions were reared in a plastic container (15 x 20 inches) in  length x width. The substrate of sandy gravel was added (1 inch) at the bottom of the boxes. Results: It was observed that there was only one dominant scorpion species, Hottentota tamulus, in Sheikhupura district. During field and laboratory observations, it was noticed that the scorpions were active during the months from March to September but became inactive and hide in the burrows from November to February. Conclusion: It is concluded that as the temperature starts to decrease, scorpions reduce their activity, hide in burrows, and undergo hibernation.
