Biological Control

provided by Deans Deitz Wharton et al
Bracon celer is a parasitoid of olive fly, Bactrocera oleae (Rossi) and efforts have been made to introduce it from Africa (where it is native) to several countries in the Mediterranean Region. As noted by Silvestri, who first reared it in South Africa, it is a color-variable species.

Biology / Hosts

provided by Deans Deitz Wharton et al
Members of the genus Bracon are amongst the most commonly encountered parasitoids emerging from infested fruits in certain parts of the world (e. g. Subsaharan Africa). Most of these species are undoubtedly parasitoids of lepidopteran and coleopteran hosts, but specific host associations have rarely been made. Other genera of the Subfamily Braconinae have also been routinely reared from fruit, but host associations for most of these are also rarely reported. It is quite possible that some of the species in these other genera may attack fruit-infesting Tephritidae.

Biology and Behavior

provided by Deans Deitz Wharton et al
The species of Bracon that attack frugivorous tephritids are idiobiont ectoparasitoids of larvae. The female wasp paralyzes the host and the larva develops on it inside the fruit, eventually spinning a cocoon and emerging as adult wasps from the fruit. Sampling programs that rely on emergence of host larvae from fruit and subsequent isolation of puparia for emergence of flies and parasitoids will either underestimate or completely miss these parasitoids.

Description

provided by Deans Deitz Wharton et al
Members of the genus Bracon_, though superficially resembling some of the Opiinae, can be distinguished by the venation of the hind wing, in which the subbasal cell (1, 2) (Fig. 6, lower left 0000223">corner) is distinctly smaller than it is in the Opiinae. All species of Bracon lack the occipital carina, whereas many of the Opiinae have the occipital carina present laterally. The labrum is exposed and distinctly concave in Bracon (Fig. 3) relative to members of the Opiinae, but this difference may not always be apparent until some familiarity with the variation in Opiinae is acquired.

Remarks

provided by Deans Deitz Wharton et al
The genus Bracon is one of the largest in the family Braconidae, with over 2000 described species. Two species, Bracon celer Szépligeti from Subsaharan Africa and Bracon fletcheri Silvestri from India have been reared from tephritid pests as part of biological control programs directed against species in the genus Bactrocera.

Bracon (wasp)

Bracon sp.

Bracon is a genus of wasps in the Braconidae, a family of parasitoid wasps. There are several hundred described species but there are thousands still undescribed.[1] The genus is cosmopolitan, distributed throughout the world, with most of the described species occurring in the Palearctic realm.[1]

These wasps are mostly ectoparasitoids, with the larvae developing on the outside of the body of the host. Recorded hosts include the larvae of many species of lepidopterans, beetles, flies, hymenopterans, and true bugs.[1] They are idiobionts, halting the development of the host when they lay eggs on its body. Some Bracon wasps are specific to one host species, and some are known to utilize many different hosts.[2] The eggs of the wasp can be very hardy. In one report, Bracon wasps oviposited on tortrix moth larvae, which then entered privet seeds and were consumed by birds along with the fruit. The wasp eggs were later excreted and the larvae emerged.[3]

This large genus has been divided into several subgenera, some of which are further divided into species-groups.[4] A DNA analysis showed that the genus is paraphyletic, that its subgenera and other defined groups are not all valid on a molecular basis, and that revising it into informal groups would be more practical.[5] Other authors still divide the genus into subgenera using morphological characters to make identification easier.[6]

Most of the thousands of species that fit into this genus have not yet been described, but even the number of named species is unclear, with estimates ranging from 500[7] to 1000.[5]

Species include:[8]
