Behavior of the tachinid parasitoid Exorista japonica (Diptera: Tachinidae) on herbivore-infested plants

Odors from corn plants infested with the larvae of the noctuid herbivore Mythimna separata (Walker) attract tachinid fly, Exorista japonica Townsend, females; and odors from corn plants artificially damaged also attract this fly. We investigated the responses of flies to herbivore-infested, artifici...

Description
Summary:Odors from corn plants infested with the larvae of the noctuid herbivore Mythimna separata (Walker) attract tachinid fly, Exorista japonica Townsend, females; and odors from corn plants artificially damaged also attract this fly. We investigated the responses of flies to herbivore-infested, artificially damaged, and undamaged plants before and after arrival at the target plants to measure timing of the behavioral sequence. The behavior of the flies for 10 min after takeoff from a release point was observed in a wind-tunnel bioassay. The percentage of flies attracted to the plants was higher in infested and artificially damaged plants than in undamaged plants. Latency before takeoff was longer in undamaged plants, and time from takeoff to arrival at the plant was also longer in undamaged plants. Moreover, flies stayed longer on infested and artificially damaged plants. Flies walked longer on infested plants than on artificially damaged and undamaged plants. In this paper, we summarize the behavioral data and discuss the host-searching behavior of E. japonica females.
