The First Record of Trichogramma chilonis Ishii in Tibet Region

doi:10.16409/j.cnki.2095-039x.2022.05.007

Abstract

Abstract: To investigate native species of Trichogramma in Tibet region, the present study collected populations of Trichogramma spp in the orchard locating in Gama district, Nyingchi city of Tibet region. The Trichogramma spp was identified as Trichogramma chilonis Ishii by the alignment of ITS2 sequence. The emergence rate of offspring was 80%. The female ratio was 57.14%. The duration of starvation tolerance was 1.08 day. The hind tibia length of female offspring was 157.6 μm. The results are expected to provide reference for the investigation of native Trichogramma species in Tibet, and support the application of Trichogramma in the biological control program in Tibet.

Key words: Trichogramma, ITS2, molecular identification
