Aceratoneuromyia

A. indica has been widely used in biological control of tephritid pests both in the New and Old World. It was initially described from material collected by G. Compere, who released it in Western Australia against medfly. Compere also sent cultures to Silvestri in Italy (as early as 1909, though this first release was unsuccessful) and Lounsbury in South Africa.

A listing of A. indica introductions in the New World for biological control is provided below summarized from Ovruski, Aluja, Sivinski, and Wharton 2000:

Mexico—introduced in 1955 against Anastrepha ludens, A. obliqua; specimens recovered, established (Clausen 1978, Jimenz-Jimenz 1959, Jimenz-Jimenz 1961).
Costa Rica—introduced in 1955 against Ceratitis capitata; specimens recovered, established (Vaughn 1992, Wharton 1989, Wharton et al. 1981).
Nicaragua—introduced in 1958, 1971 against Anastepha spp. and C. capitata; specimens recovered, established (Vaughn 1992, Wharton et al. 1981).
Argentina—introduced in 1961, 1986 against C. capitata, A. fraterculus; specimens recovered, established (Altieri et al. 1989, Ovruski 1995, Turica 1968).
Bolivia—introduced in 1969 against C. capitata, Anastrepha spp.; specimens recovered, established (Altieri et al. 1989, Bascope 1994, Pruett 1996, Vaughn 1992).
Panama—introduced in 1971 against C. capitata, Anastrepha spp.; (Wharton et al. 1981).
Venezuela—introduced in ? against Anastrepha spp.; specimens recovered, established (Hentze et al. 1993).

Known hosts include members of the tephritid genera Anastrepha, Bactrocera, Dacus, and Ceratitis.

Aceratoneuromyia indica is a gregarious, koinobiont endoparasitoid. The female wasp oviposits into late instar larvae and the progeny emerge from the puparium of the host. Detailed biological information on this species has been published by Silvestri [Silvestri (1913) (Italian version) and Silvestri (1914) (English version)]. Development during summer months in the Mediterranean region is as short as 2-3 weeks.

Eulophids are generally recognized by their four-segmented tarsi (Fig. 1: note that the dark portion at the apex is not a segment but the pretarsus, which includes the claws and the large pad between the claws). Aceratoneuromyia indica can be distinguished from most other eulophids that have been reared from tephritids by the color of the wing and body, and by the arrangement of setae on the thorax (1, 2). The species of Tetrastichus tend to have a bluish color pattern and dark (blue to black) coxae, trochanters, and femora whereas A. indica is brown (including the coxae), with the remainder of the legs yellowish (Fig. 2). Species of Melittobia that occasionally attack Tephritidae may also be similar in coloration to A. indica_, but the pronotum and 0000556">mesonotum of Melittobia are both covered with numerous short setae. In A. indica_, the setae are few in number (usually 2-3 pair on the 0000556">mesonotum: Fig. 3), and much longer (longer than the tibial spurs).

This species was originally described from material collected in India by G. Compere, and has subsequently been widely distributed following its culture and release in Hawaii. Ovruski et al. (2000) list this species from 8 countries in the New World. See also Clausen (1978).

Only one species in this genus, A. indica (Silvestri), has been recorded from tephritid hosts.

The genus name Syntomosphyrum was often used in the older literature on this species.

Aceratoneuromyia is a genus of hymenopteran insects of the family Eulophidae.
