Abstract

Sunn pest egg parasitoid, TRISSOLCUS SEMISTRIATUS (Hym., Scelionidae), was reared on eggs of two species of bugs, Graphosoma lineaturn (Het.. Pentatomidae) (Ts-Gr) and EURYGASTER INTEGRICEPS (Het., Scutelleridae) (Ts-Eu), for two generations. Functional and NUMERICAL RESPONSEs of the two groups were compared.A one day old female parasitoid of the two groups were introduced to 8 density levels (2, 4, 7, 14, 28, 42, 56 and 70) of one day old eggs of Sunn pest, E. integriceps. in 9 replicates for 8 hrs. Experiments conducted at 25± 0.5°C, 45±5% RH and l6L:8D h photoperiod. Type II and III FUNCTIONAL RESPONSEs were shown by Ts-Eu and Ts-Gr, respectively. Ts-Eu had higher searching efficiency (a) and lower handling time (Th) than Ts-Gr. Maximum attack rate (T/Th)reached 63.49 and 20.25 for Ts- Eu and Ts-Gr. respectively. NUMERICAL RESPONSE ofTs-Eu to cumulative densities of host eggs was linearly increasing, but was domed shape for Ts-Gr.
