Effect of Short-Term High-Temperature Stimuli on the Functional Response of (Matsumura).

Researchers have previously investigated the role of as a pupal parasitoid in the biological control of in China. Here, we investigated the ability of to parasitize pupae at different temperatures. To do this, we evaluated the functional response of to pupae at different temperatures and investigated the specific effects of density on parasitism. The results show that the parasitic functional response of under different high-temperature stimuli is Holling type II. After processing at 29 °C, the instantaneous search rate was 1.1611; the theoretical maximum parasitic value was 20.88 at 31 °C. The parasitic efficiency decreased with increasing stimulation temperature, as the host pupa density increased from 5 to 25, and the strongest search effect occurred at 0.87 at 27 °C. The searching effect of at each temperature fell gradually with an increase in prey density from 5 to 25. At 31 °C, the theoretical parasitic maximum of reached a maximum of 20.88 pupae. At this temperature, when a pair of was placed in a pupa density of 50, its actual total number of parasites was 18.60.
