“…Following exploration for natural enemies to control the introduced species of Scupteriscus mole crickets in the United States, 0. depleta (Townsend) was attracted in large numbers to artificial sound sources, and was reared from field collected mole crickets (FOWLER and KOCHALKA 1985;FOWLER 1987bFOWLER , 1987cFOWLER and MESA 1987;FOWLER and GARCIA 1987).…”

“…Although 0. depletu is highly phonotactic to the calls of male mole crickets (FOWLER and MESA 1987;FOWLER 1987aFOWLER , 1987b, little is known of the larval behavior, except for experimental innoculations of hosts in the laboratory (FOWLER and GARCIA 1987). Gravid females larviposit near the sound source (FOWLER 1987c), and the planidia larvae are known to leave their mother's body and disperse.…”

The dispersion patterns of the larval planidia of Ormia depleta was studied in circular arenas. After placing 25 larvae in the center of the arena, their angle of distribution and distance travelled was recorded 15 min later. No innate directional orientations were evidenced, nor was evidence found for either positive or negative orientation to point sound and light sources. In all cases, dispersion was bimodal, with most dispersing only 1 cm, and a much smaller peak found at 10 cm. The bimodality of dispersal distances may be a response to the sexual behavior of its host, mole crickets of the genus Scapteriscus. Zusammenfassung Zur Larvenausbreitung beim Parasitoiden Ormia depleta (Towns.) (Dipt., Tachinidae) Das Ausbreitungsmuster der Larven der Maulwurfsgrillen‐Tachine Ormia depleta wurde im Labor auf runden (mit feuchtem Filterpapier bedeckten) Flächen untersucht. Nach Placierung von je 25 Larven im Zentrum der Arena wurden 15 Min. später der Ausbreitungswmkel und die zurückgelegte Entfernung registriert. Es wurden weder eine endogene Richtungsorientierung, noch eine positive oder negative Orientierung gegenüber Ton‐ und Lichtquellen festgestellt. In allen Fällen war die Ausbreitung bimodal mit einem absoluten Ausbreitungsmaximum von nur 1 cm; ein viel geringeres Maximum lag bei 10 cm. Die Bimodalität der Ausbreitung könnte eine Antwort auf das Sexualverhalten des Wirtes, einer Maulwurfsgrille der Gattung Scapteriscus, sein.

Euphasiopteryx depleta (Wied) flies successfully developed in the mole crickets Scapteriscus borellii Giglio-Tos and Scapteriscus vicinus Scudder, as well as in the short-tailed cricket, Anurogryllus sp., after artificially placing larvae under their pronota. Using this technique, no relation was found between the number of larvae placed on each cricket and the resulting number of puparia obtained from the cricket. In all cases, the number of flies emerging from the puparia was small, with females failing to mature reproductively. As E. depleta has been reared from field collected Scapteriscus spp., the exact reasons for lack of maturation remain unknown. Anurogryllus sp. can be considered a probable alternate host for E. depleta.
