| Abstract |
The variations in the total body weight, water content, dry weight, and total ash of Tribolium confusum during metamorphosis are reported. A drop in total body weight before the insect enters pupation is observed. The pupal stage shows a moderate but sustained decrease in body weight followed by a further large one at emergence. Though the water content falls during the prepupal stage and at the emergence, there is a moderate increase in the water content during the pupal stage. These changes show that the pupae utilize the reserves accumulated during the larval stage. Variations in both dry weight and total body weight are similar. A study of simple correlation of these variables is discussed. The elimination in the prepupal stage of a large amount of the inorganic constituents (ash) is noticed. During the pupal stage, total ash remains constant while at emergence, there is a slight fall. |
