| Abstract | ||
| Changes of total hemocyte counts (THC) and blood volume (BV) were studied in order to estimate the modification of absolute hemocyte counts (AHC) during the different developmental periods of the last larval instar of the mulberry silk worm Bombyx mori. The THC reached its peak during the early spinning period whereas, the BV and AHC presented their peaks on the 10th day. An inverse relationship was noted between the THC and blood volume on the 4th and 9th days, and also between the 11th day and until the prepupal period. No correlation was observed between the BV and the THC during the periods between the 4th and the 5th days, and between the 9th and 10th days. A striking decrease of AHC is accompanied by a decline of THC and BV during pupation. | ||
