Abstract:

The defense response of hemolymph in the larvae of Apriona germari to Beauveria bassianawere studied. The result showed that the kind and number of hemocytes in control Apriona germari larvae were stable, while Beauveria bassiana conidia had significant impact on the number of the hemocytes in Apriona germari larvae. The total number of hemocytes did not change significantly within the 1stday after inoculation. It increased gradually after one day, and reached to maximum in two and half days after inoculation. Then it decreased gradually to the lowest level. The counts of Plasmatocyte and Granulocyte of the hemocytes in the infected Apriona germari larvae showed similar pattern.

Key words: Apriona germari, Beauviera bassiana, hemocyte, defense reaction
