The effects of the microsporidian parasite Vairimorpha necatrix (Kramer), a potential biological control agent, were evaluated in Heliothis zea ( Helicoverpa ) (Boddie) larvae raised in the laboratory at various temperatures (15, 20, 25, and 30°C). The target organ of infection was the larval fat body. Histopathologic changes in the fat body of the parasitized larvae included a congested appearance of the cells, decreased amounts of intracellular lipid, and loss of cellular structure and… CONTINUE READING
