| Abstract | ABSTRACT: This study compared the Aphelinus varipes and Aphelinus asychis in terms of how they parasitized the cotton aphid, Aphis gossypii and green peach aphid, Myzus persicae. Host-feeding, parasitism, emergence, the proportion of females and development time were all studied at 15, 20, 25 and 30 ℃ in controlled climate cabinets. When A. gossypii were provided for the two aphid parasitoids, the number of aphids killed by host-feeding for A. varipes (5.4 and 9.7 aphids) at 15 ℃ and 25 ℃ was higher than those for A. asychis (2.0 an d2.9 aphids). At 15℃ and 30℃, the parasitized A. gossypii were higher in A. varipes (11.1 and 21 aphids) than in A. asychis (7 and 12.3 aphids). The emergence rate was also significantly different between A. varipes (83.3%) and A. asychis (69.4%). The proportion of femaleswas higher for A. asychis (75.2 and 73.9%) than for A. varipes (19.5 and 48.6%) at 15 ℃ and 30 ℃, respectively. No significant difference swere found in development time between the two parasitoids. When M. persicae were provided for the two parasitoid species, the host-feeding number and the emergence rate of two parasitoids were not different at all four temperatures. The M. persicae were more highly parasitized by A. varipes (12.1 and 17.1 aphids) than by A. asychis (6.1, 10 aphids) at 20 and 25 ℃. The proportion of females fo rA. varipes (65.3 and 90.0%) was higher than that for A. asychis (34.4 and 78.8%) at 15 ℃ and 25 ℃. The development time from ovipositio nto the adult emergence of A. varipes (19.9 d) was significantly longer than that of A. asychis (16.5 d) at 20 ℃. Development times decrease dwith increasing temperature for both in two parasitoid species.
