Abstract

Haemocytes of L. migratoria are categorized on the basis of morphological characteristics of spread cells in four groups, namely plasmatocytes, granulocytes, coagulocytes and prohaemocytes. In the current study the cell number fluctuation was studied during the progress of infection. The results showed that the total haemocyte count (THC) increased during the first three days of infection and decreased subsequently (significant at 99% confidence interval comparing controls). Regarding Differential Haemocyte count (DHC), the similar trend was observed, although the relative percent of coagulocytes increased compared to the other three cell categories. Furthermore, along with the spreading of disease the phagocytic potential of blood cells decreased and prior to insects death these cells were unable to spread their pseudopodia to engulf fungal elements. Although the blood cells were able to phagocytise the aerial conidia injected to insects’ haemocoel in the beginning of infection and blastospores produced in the course of fungal proliferation, these fungal elements were not killed and after germination or multiplication they destroyed the cells, in which they enclosed and colonized their host body. The other impact of the disease on insects cellular IMMUNE SYSTEM was the production of granulomas that were sometimes without fungal elements and were produced under the effects of fungal metabolites.
