“…Two adult parasitoid species, Centistes gasseni (Hymenoptera: Braconidae) and Celotoria bosqi (Diptera: Tachinidae), are known to parasitize D. speciosa and D. viridula , but with extremely low incidences in the latter. Celatoria compressa (Diptera: Tachinidae) is known to parasitize D. balteata in North and Central America, with no records for South America [ 104 , 105 , 106 , 107 ]. Other than these, at least 10 generalist predators have been recorded for adult D. speciosa [ 108 ].…”

“…Natural parasitism levels in D. speciosa have been reported between 1 and 28%, and on rare occasions over 30% [ 105 , 106 ]. Furthermore, the higher levels of parasitoidism are always recorded toward the end of the growing season, when most of the crop damage is done, suggesting that natural control levels are of minor importance to pest management [ 108 ].…”

The genus Diabrotica has over 400 described species, the majority of them neotropical. However, only three species of neotropical Diabrotica are considered agricultural pests: D. speciosa, D. balteata, and D. viridula. D. speciosa and D. balteata are polyphagous both as adults and during the larval stage. D. viridula are stenophagous during the larval stage, feeding essentially on maize roots, and polyphagous as adults. The larvae of the three species are pests on maize, but D. speciosa larvae also feed on potatoes and peanuts, while D. balteata larvae feed on beans and peanuts. None of these species express a winter/dry season egg diapause, displaying instead several continuous, latitude-mediated generations per year. This hinders the use of crop rotation as a management tool, although early planting can help in the temperate regions of the distribution of D. speciosa. The parasitoids of adults, Celatoria bosqi and Centistes gasseni, do not exert much control on Diabrotica populations, or show potential for inundative biocontrol plans. Management options are limited to insecticide applications and Bt genetically modified (GM) maize. Other techniques that show promise are products using Beauveria bassiana and Heterorhabditis bacteriophora, semiochemical attractants for monitoring purposes or as toxic baits, and plant resistance.

“…Since C. diabroticae never attacked C. trifurcata in laboratory host range tests, it seems likely that McConnell's report was based on a misidentification of the parasitoid (Fischer 1983). To date, it remains unknown which Celatoria species is found on Cerotoma trifurcata in the USA (Danielson, Brandle, and Blanchard (1937), Christensen (1943), Parker et al (1951), D'A.-Silva et al (1968, Gassen (1984Gassen ( , 1989, Salles (1996), Heineck-Leonel and Salles (1997), Cabrera Walsh (2004) (2005) [ ] Citations that are not verified by ensuing surveys or by host range tests (see Table 4). f fucata group species.…”

The subtribe Diabroticina is a large group of New World Chrysomelidae that includes corn rootworms, cucumber beetles and other pests. Recent introductions of Diabrotica virgifera virgifera LeConte into Europe, and the development of resistances to current management practices of rootworms in the USA have increased interest in new sustainable options for managing those pests. The only parasitoids that have been shown to consistently target and develop inside the beetle adults are Centistes gasseni Shaw, Centistes diabroticae Gahan (both Hym.: Braconidae), and Celatoria diabroticae Shimer, Celatoria compressa (Wulp), Celatoria bosqi Blanchard, and Celatoria setosa Coquillett (all Diptera: Tachinidae). This review improves our understanding of the realised and potential host range of these known parasitoids by rectifying erroneous references in light of new host records and from laboratory host range tests. Based on this critical review, all tachinid and braconid species studied are considered to be specific at least to the level of subtribe, i.e. Diabroticina. Celatoria setosa, Celatoria diabroticae and C. bosqi, have a narrow realised and potential host range; the former is restricted to the genus Acalymma and the last two to the fucata and virgifera groups of the genus Diabrotica. The braconids Centistes gasseni and C. diabroticae are also specific. The realised host range of C. gasseni includes species in the Diabrotica fucata and virgifera groups; while its potential host range also includes Acalymma species. The realised and potential host range of Centistes diabroticae includes Acalymma species as well as species in the fucata and virgifera groups of Diabrotica. Celatoria compressa has the broadest realised range compared to the other species studied, since it was obtained from species in several genera of Diabroticina; and its potential host range may also include Old World Aulacophora species.

We report the incidence of striped cucumber beetle (Acalymma vittatum [Fabricius]) (Coleoptera: Chrysomelidae) parasitism in bi-weekly samples from diverse farm locations in central New York State over the course of two growing seasons. Two parasitoid species not previously verified in this geographic region were found: Celatoria setosa (Coquillett) (Diptera: Tachinidae) and Centistes (Syrrhizus) diabroticae (Gahan) (Hymenoptera: Braconidae). Parasitism by C. setosa, up to 43%, [mean 8.67%] was comparable to previously published rates. Contrary to the expectations of earlier authors, however, C. diabroticae was found to be ubiquitous and maximum rates of parasitism (*54%) were [threefold greater than the only other published report for this species [C. diabroticae mean 14.36%]. In laboratory assays, we investigated C. diabroticae larval development. We also tested the effects of wasp clone and host beetle sex on C. diabroticae larval development. This is the first documentation of life cycle information for this braconid.
