Abstract

Abstract: Eretmocerus hayati (Zolnerowich & Rose) and Encarsia sophia (Girault & Dodd) are efficacious parasitoids of Bemisia tabaci (Gennadius). To explore the use of these two parasitoids in protected agriculture that is characterized by high temperature, the influence of different developmental temperatures (26, 30, 34, 38℃) on the size and egg load of newly emerged female of these two parasitoids was evaluated in this current research. The results showed that, with increasing developmental temperature, the body size of both parasitoid females decreased. The body size of E. hayati females developed at 38℃ was smaller than those developed at other developmental temperatures. The body size of E. sophia females developed at 38℃ was smaller than those developed at 26 and 30℃. The egg load of both parasitoid females showed decreasing tendency with increasing developmental temperatures. The egg load of E. hayati developed at 30℃ was higher than that at 34℃, followed by those at 26 and 38℃. There were no significant differences in the egg load in E. sophia females developed at 26, 30 and 34℃, while no mature eggs were observed in females developed at 38℃. Regardless of temperature, the body size and egg load of E. hayati were larger than those of E. sophia. Our results confirm the Temperature-Size Rule, and can help mass rearing of the parasitoids and their use in biological control of B. tabaci at high temperatures in greenhouse.

Key words: Eretmocerus hayati, Encarsia sophia, temperature, body size, egg load
