Diseases Several disease organisms com- monly infect soybean pests. Per- haps the most important natural control agent of the green clover- worm in Illinois is ...the fungus Nomuraea rileyi (Fig. 47). Lepidopterous caterpillars are infected by the spores of this fungus, and upon germination the mycelium completely fills the body cavity, killing the larva. The body becomes hard and mummi- fied and is covered with a white layer of external conidiophores. Under hot, humid conditions the fungus sporulates, encasing the cadaver in powdery, light green spores. Detection of the disease may signal the decline of the pest population. It is therefore important that you recognize the presence and spread of the disease when surveying pest populations in soybean fields.
