Laboratory studies were conducted to investigate the effect of selected temperatures on the development, mortality, sex ratio, and emergence rate of Trichogramma dendrolimi Matsumura reared from a factitious host, oak silkworm, Antheraea pernyi (Guerin-Meneville) eggs. The comparison tests were conducted to investigate the fecundity on Dendrolimus spectabilis (Butler) eggs of T. dendrozimi reared from natural and factitious hosts. and artificial hosts. Developmental periods from egg to adult of T. dendrolimi reared at 26, 28, 30, and 32$^{\circ}$C were 10.9, 9.6, 9.0, 8.6 days, respectively. Emergence rates of T. dendrolimi decreased 78.0, 38.4, 60.7, and 50.1% as temperature increased. The progeny sea ratios (i.e.. females per male) ware 7.3, 8.4, 8.2 and 6.9 at the respective temperatures . When adult T. dendroiimi emerged from A. pernyi eggs were kept in dark conditions for storage at different temperatures for 34 days, their mortality increased as temperature increased: O% at $0^{\circ}C$; 10% at 4$^{\circ}$; 40% at 6$^{\circ}$; 50%at 18$^{\circ}C$ and 100% at $\geq$26$^{\circ}$ The fecundity of T dendrolimi reared from three different hosts was investigated on D. spectabilis eggs. During the first day,7he adult T. dendrozimi reared en A. perayi eggs laid most eggs (99.0 $\pm$ 10.7), followed by those reared on artificial hosts (76.6$\pm$24.5) and D. spetrabilis eggs (63.4$\pm$ 35.9), Over the entire lifespan, T. dendrolimi reared on D. spectabizis eggs produced the highest number of eggs (218.0 $\pm$ 27.9), followed by A. pernyi eggs (104.0$\pm$44.7) and artificial host (98.2 $\pm$ 37.1). These results suggest that the to temperature and three hosts factors had an effect on rearing of the T. dendrolimi on the factitious host, A. pernyi eggs.
