“…Several species of Trichomalopsis, particularly Trichomalopsis dubius Ashmead, have been collected and studied in various parts of North America (Hoebeke and Rutz 1988, Geden et al 1992, Dobesh et al 1994, Lysyk 1998). However, Graham (1969) suggests that Trichomalopsis Crawford might be the same as Eupteromalus Kurdjumov; many European species of Eupteromalus are undescribed and the entire group needs revision.…”

Hymenopteran Pupal Parasitoids Recovered from House Fly and Stable Fly (Diptera: Muscidae) Pupae Collected on Livestock Facilities in Southern and Eastern Hungary

This Þeld survey, the second noting the occurrence and diversity of Þlth ßy pupal parasitoid fauna in Hungary, was performed on beef and dairy feedlots and swine facilities in the southern and eastern parts of the country. The Þlth ßies Musca domestica L. and Stomoxys calcitrans (L.) were the two most commonly parasitized hosts. The three species of Spalangia recovered, in decreasing order of abundance, were S. cameroni Perkins, S. nigroaenea Curtis, and S. endius Walker. Pachycrepoideus vindemiae Rondani, Trichomalopsis sp., two apparently undetermined Diapriidae spp. and one apparently undetermined Brachycera sp. are believed to be new country records.

“…This species has a broad range of dipteran hosts and wide distribution in North America (Gibson and Floate 2001). It was first reported as an occasional parasitoid of house fly in cattle feedlots of Nebraska in the United States of America, where it was identified as Trichomalopsis near americana (Dobesh et al 1994). Lifetime fecundity of this Nebraska population was identified at about 110 eggs/female under optimum laboratory conditions; however, because females lay several eggs on each house fly pupa, the potential number of house flies killed by oviposition in the field is much lower.…”

“…Lifetime fecundity of this Nebraska population was identified at about 110 eggs/female under optimum laboratory conditions; however, because females lay several eggs on each house fly pupa, the potential number of house flies killed by oviposition in the field is much lower. Based upon the pattern of gregarious oviposition and its low occurrence in nature, Dobesh et al (1994) concluded that T. sarcophagae would be less effective as a biocontrol agent than species of wasps already commercialized.…”

“…Unlike the Nebraska population, which was recovered from <1% of sentinel house fly pupae parasitized in the field (Petersen and Watson 1992), recoveries of the Alberta population have ranged from 12 to 24% of parasitized sentinel pupae (Lysyk 1995;Floate et al 1999). Furthermore, the Nebraska population is essentially unable to develop at temperatures ≤20°C (Dobesh et al 1994), whereas the Alberta population develops at temperatures as low as 15°C (Lysyk 1998). The Alberta population also exhibits gregarious oviposition and produces numbers of progeny comparable with the Nebraska population (Dobesh et al 1994;Lysyk 1998).…”

Field trials of Trichomalopsis sarcophagae (Hymenoptera: Pteromalidae) in cattle feedlots: a potential biocontrol agent of filth flies (Diptera: Muscidae)

A field study was performed in southern Alberta, Canada, to assess the native wasp, Trichomalopsis sarcophagae (Gahan), as a potential biocontrol agent for house fly, Musca domestica L., and stable fly, Stomoxys calcitrans (L.). The wasp was readily reared in large numbers, which allowed for the cumulative release of an estimated 4.63 million wasps into three commercial feedlots during the 2-year study. Each of several releases predictably and repeatedly enhanced parasitism of sentinel house fly pupae, whereas parasitism remained low in three paired control feedlots where wasps were not released. Releases every 2nd week had a disproportionately greater effect than releases every 2nd month. In 1998, 1.2 million wasps were released into treatment feedlots resulting in the recovery of 3 952 T. sarcophagae from 31 500 sentinel pupae (0.13 wasps/pupa). In 1999, 3.43 million wasps were released into treatment feedlots, with the recovery of 37 763 wasps from 47 720 sentinel pupae (0.79 wasps/pupa). Hence, a 2.8-fold increase in the number of wasps released in 1999 resulted in a 6.1-fold increase in the recovery of wasps. This result supports industry recommendations of regular, repeated releases of wasps every 2nd or 4th week versus one or infrequent releases throughout the summer. There was no evidence that releases augmented overwintering populations of the wasp in subsequent years. These results provide proof-of-concept for the mass-rearing and release of T. sarcophagae as an inundative biocontrol agent for the control of pest flies in cattle confinements. Further studies will be required to assess the effect of T. sarcophagae releases on natural populations of pest flies.

“…Although the gregarious nature of parasitoids has been reported as not being a desirable trait, with respect to such species as Trichomalopsis spp. (Dobesh et al 1994). The gregarious nature of M. raptorellus is considered a very desirable trait because each female not only attacks a large number of ßy pupae but each parasitized ßy pupa also generally produces multiple offspring (Petersen and Currey 1996b), all of which contribute to parasitoid recycling, an important component to ßy biological control.…”

Commercially obtained Nasonia vitripennis Walker and Muscidifurax raptorellus Kogan & Legner were released weekly for 12 wk into a high-rise, caged-layer poultry house. After the release period, parasitoids were sampled using sentinel house fly (Musca domestica L.) pupae that were either laboratory-reared or field-collected as larvae and exposed for 2, 4, 7, and 14 d. Parasitoid-induced mortality was observed in 31% of laboratory colony pupae and in 26% of field-collected pupae, whereas successful parasitism rates of 48 and 51% were observed from these pupal sources, respectively. Parasitism was primarily by M. raptorellus (88%), and Muscidifurax raptor Girault & Sanders (11%), while N. vitripennis accounted for <1%. Percent female progeny ranged from 43%, in M. raptorellus to 76% in N. vitripennis. Parasitoid emergence from 2-d exposed sentinel pupae was the lowest of all treatments. Parasitoid emergence from 7-d exposed sentinel pupae was the highest of all treatments. We found no differences between pupal source, suggesting that when sampling for M. raptor, M. raptorellus, and N. vitripennis, in poultry facilities, pupal source is not a confounding factor.
