Abstract
Verson (1908) found that silkworm hemocytes did not enter the heart, and stated that this was because of the narrowness of the ostial slits. Absence of hemocytes from the silkworm heart was noted by Masera (1933) in his study on pulsation rates. According to Weber (1935) the hemocytes of adult Aleurodes are too large to enter the heart and only plasma circulates through it. Wiggles worth (1950) found that the hemocytes in Rhodnius fail to enter the heart lumen and on the basis of this observation and those of the previously mentioned workers has concluded that in insects “… only cell-free hemolymph can be said to truly circulate.” He goes on to say that “… it is obvious, therefore, that the numbers of circulating cells must vary enormously from time to time.”Keywords
