“…Yeh et al (2005) reported a significant depression in haemolymph osmolality that mainly resulted from a decrease in the haemolymph chloride concentration (Cl -1 ) in the prawn, Macrobrachium rosenbergii, after 8 days of exposure to sublethal concentrations of trichlorfon. However, a decrease in haemolymph pO 2 was found among these prawns, which may be related to decreased ventilation and impeded respiratory gas exchange, leading to respiratory disturbances via the inhibition of respiratory mechanisms and damage to respiratory organ epithelial cells.…”

“…These changes can be used to characterize the genotoxic, physiological, and biochemical effects of pollutants. Therefore, hemocytes (via changes in cell number and development of structural abnormalities) are frequently used to demonstrate the cytogenetic damage caused by toxic chemicals (Yeh et al, 2005). Genotoxicity biomarkers are widely measured in ecotoxicology as molecular toxic effects of major environmental pollutants (Wessel et al, 2007).…”

In the present study, the effects of deltamethrin on cell-mediated immune response and genotoxic damage of Galleria mellonella (Lepidoptera: Pyralidae) were investigated. Different concentrations of deltamethrin (5, 20, 50, 100, and 150 µg) were administered to G. mellonella at 24, 48, 72, and 96 h. Five types of hemocytes were identified in G. mellonella: prohemocytes, plasmatocytes, granulocytes, spherulocytes, and oenocytes. Total hemocyte counts (THCs) were significantly affected by deltamethrin. At 72 h, THCs of the treated group had significantly decreased compared with the control groups at high deltamethrin concentrations (50, 100, and 150 µg); however, at 96 h, THCs had significantly increased at deltamethrin concentrations of 100 and 150 µg. Micronucleus formation was significantly affected by deltamethrin; in particular, high concentrations of deltamethrin (100 and 150 µg) caused an increase in micronucleus formation at all time points. We conclude that deltamethrin affected THCs and caused the induction of micronucleus formation via genotoxic damage in G. mellonella.

“…Based upon the recent classification of M. rosenbergii haemocytes (Sierra et al, 2001) large ovoid haemocytes and undifferentiated round haemocytes might be carrying out the functions of the proPO system, like semigranular and granular haemocytes in other crustaceans (Johansson and Soderhall, 1989). The activity of phenoloxidase has already been reported in M. rosenbergii (Jaya Kumari et al, 2004;Yeh et al, 2005;Smith et al, 1984 andChang et al, 2000). Therefore, the health of prawn and enhancement of its immunity are of primary concern.…”
