TI - Effects of subleathal dosages of flufenoxuron and chlorfluazuron on haemolymph changes of spodoptera littoralis KW - Spodoptera littoralis KW - Control KW - flufenoxuron KW - chlorfluazuron N1 - Includes references N2 - The present study aims to investigate the changes of haemocytes in the 6th larval instar of S. lit/oratis haemolymph as a result of treatment of the 3rd larval instar with LC₂₅. LC₅₀ and LC₇₀ of two insect growth inhibtors, flufenoxuron and chlorfluazuron. Several pathological cases were observed in the haemocytes (plasmatocytes. prohemocytes. granulocytes, spherulocytes and oenocytoids) including variation in the cell volume, vacuolization in the cytoplasm, distortion in the cellmembrane and pycnosis of nuclei. At the same time the change in the total and differential haemocytes counts were recorded UR - http://nile.enal.sci.eg/EALE/2007/ICEE/Conf/207/211.pdf ER -
