Habrolepis Förster 1856

Hosts. Hemiptera : Diaspididae

rouxi Compere 1936a: 495

Type. BMNH

Distribution. E (San Diego)

Host/habitat. Aonidiella aurantii , A. citrina , A. orientalis , A. sp., Aspidiotus nerii , A. sp., Chrysomphalus aonidum , C. sp., Hemiberlesia rapax , Parlatoria oleae , Selenaspidus articulatus

Remarks. First imported from South Africa and released against Aonidiella aurantii in southern California and Fresno in the late 1930s, this species proved to be ineffective, as the report of its establishment in California is based on the 1943 recovery from a single orchard in San Diego ( Flanders 1944). This species was reimported from South Africa against Parlatoria oleae and released in Fresno County from 1940–42; although it reproduced on this species, it failed to establish in the field ( Huffaker et al. 1962). In the 1970s it was imported from Saudi Arabia and cultured in quarantine ( DeBach 1977), but I found no record of subsequent releases. Thus, it is quite possible that this species is no longer extant in the state. DeSantis (1979) reported Carulaspis minima (Signoret) as a host, but it is not clear what this is based on—Bennett & Hughes (1959) had previously reported that H. rouxi had been moved from California to Bermuda in a biocontrol program directed against that species, but there was no evidence actually citing C. minima as a suitable host. Blumberg & DeBach (1979) noted that H. rouxi would attack Aspidiotus nerii in the lab, but it wasn’t a completely suitable host. Noyes (2001), citing Flanders (1944), recorded Neoselenaspidus silvaticus (Lindinger) as a host, but the earlier paper only noted that this scale species was heavily parasitized without identifying the parasitoid.

Remarks. What appears to be an undescribed species has been collected from a pit scale on a Quercus sp. in Marin (EMEC), as well as on Adenostoma fasciculatum , Cercocarpus betuloides (Rosaceae) , Pinus sabiniana (Pinaceae) , Quercus agrifolia , Q. douglasii , Salix ? lasiolepis ( Salicaceae ), and Umbellularia californica (Lauraceae) in Alameda, Contra Costa, Humboldt, Stanislaus, Sutter and Tuolumne counties (CAS, RLZC, UCDC, UCFC).
