In early October 1984, larvae were harvested on the Babao tree in the specimen garden of the institute (see Figure 1 of cover two). In the indoor use of insect nests (size 10 × 15cm, and alcohol disinfection) feeding, to October 18 larvae all died. Most of the fallen dead bottom of the cup, body color black, the skin is not easy to break (see cover two Figure 2). Microscopic examination of dead insects, a large number of polyhedra.
