Studies of some aspects of post natal developmental stages of a serious wild rodent species (rattus sikkimensis) in the laboratory conditions

Chattopadhyay, D. P., Banerjee, A. and Manna, C. K.

Abstract: 

Among the vertebrate pests, the rodents are quite important as they have a direct interactions with the human beings and the locality. Most of the rodents are prolific breeder and breed throughout the year. This study is concerned with one serious rodent species, the Rattus sp. (Rattus sikkimensis) usually found in some portions of the District Nadia and North 24-Parganas, West Bengal, INDIA. Due to the wild nature of this species, it is very difficult to study the growth and process of development especially during the post natal stages. For this reason some pregnant female wild Rattus sp. were trapped with the help of some young Oraon Tribal community. Just immediate after trapping the females were taken in the laboratory and kept within separate cages in the well maintained animal house. After giving birth to the new born individuals, they were nurtured by the mother. The changes were noticed upto the age at maturity. All the changes were noticed in the laboratory conditions. As this species is a prolific breeder and causes serious types of damages to the crops so the study of various developmental stages of this species will be an important aspect for the maintenance of this rodent pest.
