Abstract:Trichodes sinae Chevrolat is the main parasitoid of Hoplitis pyrrhosoma Wu, a very important pollinator in West Erdos Region, Inner Mongolia of China. This paper reports its immature morphology, life history and biological characteristics. The species completes one generation a year in West Erdos Region. They pupate in early April. The adults emerge from mid May to early June. After having took some plant nutrition, the beetles begin to mate and lay eggs. The first instar larvae are able to find and get into the nest of H. pyrrhosoma, then prey the larvae until it becomes callus. At room temperature, the egg stage is about 6~8 days, the larval stage about 260~280 days, and pupa about 40~50 days; the male adult's longevity is about 28~30 days and the female's about 35~40 days.
