ULTRASTRUCTURE AND PATHOGENICITY OF A MICROSPORIDIAN FROM LOCUST IN CHINA

Wang Liying; Cao Chun (Department of plant protection,Beijing Agricultural University,Beijing, 100094)  
The ultrastructure and development of a microspori dian,isolated from the dead body of ori ental migratory locust (Locusta migratoria manilensis) in Hebei province was observed under light-and electron-microscope. The meront was spherical or ovocylindrical containing uni-, bi-,quadri-and multinucle ate forms. The hexa-,eith-nucleate meronts measured 6. 9 ×7. 9μm were peculiar to this strain. The ultra strructure of stages in the life cycle of the mictosporidia showed that merontsdeveloped in direct contact with the host cell cytoplasm and bi-,guadrinucleates meronts were arrangment two nuclei in a diplokary on. Sporonts were differentiated from meronts with the thickened plasmalemma and observed undergoing cytokinesis. Stratified electron-dense strands were depostied in the host cell cytoplasm and sporont plas malemma surface.Studies of pathogenicity showed that the mortality increased as the dosage rised1the third-instar was more sUsceptible than that of the fourth;the mortality of locusts reard together was higher than reard sep arately;the develoment time of infected locusta were delayed 2~ 3 days ;the number of eggs infected lo custs decreased ;the food consumption of the infected was 35~ 75 % less than controlled after 24 days' inoc ulation.
