Biology of Thitarodes pui (Lepidoptera, Hepialidae), a host species of Ophiocordyceps sinensis
Thitarodes pui, one of the host species of Ophiocordyceps sinensis, is distributed in the alpine meadow and alpine shrub meadow of the Mt. Sejila in Tibet at an altitude of 4100 -4650 m. The biology of T. pui was investigated by field sampling and insectary rearing. The results showed that it was 3 to 4years, about 1095 - 1460 d for T. pui to finish a generation development, including 41 -47 d for egg development, 990- 1350 d for larva, 35 -41 d for pupa, and 3 -8 d for adult longevity, respectively.Hatching rate of eggs was significantly affected by ambient conditions. There were 7 -9 instars for larvae development. The 7th instar larvae pupated into male adults, the 9th instar larvae into female adults, and the 8th instar larvae into both males and females. Pupation occurred in the end of April to early May. Adults emerged in late June to early July. The ratio of males to females was 1.5: 1. The average oviposition was 768 ± 206 eggs per female.
