“…In the fruit, visual clues, such as oviposition, marks or surfaces marked by the development of the fly larvae, help to identify the region where the host is (STHUL et al, 2011). To specify the place where the eggs are laid, the female of this specie uses vibrations caused by feeding larva inside the fruit (LAWRENCE, 1981). This indicates that D. longicaudata can adapt to different kinds of fruit since it uses generic tracks, common to decomposing fruit, marks of oviposition activity or development of tephritids in general.…”

ABSTRACT-Diachasmimorpha longicaudata (ashmead) (hymenoptera: Braconidae) was introduced in 1994, in Northeastern Brazil, to evaluate its use in biological control programs of fruit flies. However, the effects of this specie on parasitism rates on the population of native parasitoids and fruit flies in Southern Brazil conditions are unknown. The objective of this study was to evaluate the impact of releases of D. longicaudata on the parasitism rates on loquats, peach trees, strawberry guava trees, and persimmons in an experimental area in the city of Eldorado do Sul, Rio Grande do Sul, in southern Brazil. In the first year of the study, fruits were collected and stored in the laboratory to obtain pupae. The flies or parasitoids that emerged were counted and identified. In the second year, adults of D. longicaudata were reared in the laboratory on Anastrepha fraterculus (Wied.) and larvae were released in the field (1.700 insects/ha) at each harvest time and the parasitism was evaluated in the same manner as in the first year. In the third year, the procedure was the same as the first year, without any releases. A significant increase in the rates of parasitism was recorded in the second year except in the persimmon, in which no parasitoid was recovered in any year. In the second year the number of emerged fruit flies was also lower. In the third year, no D. longicaudata were recorded and parasitism rates of parasitism were statistically similar to those found in the first year. The native parasitoids collected were Aganaspis pelleranoi (Brèthes), Doryctobracon areolatus (szépligeti), Doryctobracon brasiliensis (szépligeti) and Utetes anastrephae (Viereck). These species were found in at least one kind of fruit even in the years after the introduction of the exotic parasitoid, indicating that it was not harmful to these species. We conclude that D. longicaudata can help to reduce the population of fruit flies in Eldorado do Sul region, in Rio Grande do Sul.Index terms -biological control, Anastrepha fraterculus, Aganaspis pelleranoi, Doryctobracon, Utetes anastrephae.

“…One difficulty in rearing D. areolatus has apparently been the oviposition stimuli in oviposition units (artificial devices with third-instar host larvae mixed with food) (Eitam et al 2003), which has not been a problem in the case of D. longicaudata because this species detects its host by larval vibrations when feeding or moving (Lawrence 1981). However, in light of our new findings, new perspectives on laboratory rearing of this species are realized.…”

Natural parasitism of Doryctobracon areolatus (Szépligeti) (Hymenoptera: Braconidae) on various development stages of Anastrepha obliqua (Macquart) (Diptera: Tephritidae) attacking Spondias mombin L. fruits was studied under field conditions. We collected 120 fruits of S. mombin from which we got 495 A. obliqua larvae of different instars. A total of 88% of these larvae were parasitized. Within the parasitized cohort, the first-instar of D. areolatus was frequently detected in all 3 larval stages (L1 = 94.3%, L2 = 98.1%, and L3 = 100%), and the rest (i.e., L1 = 5.7%, L2 = 1.8%) corresponded to the presence of eggs. In fruits with controlled infestation and cage-induced parasitism under field conditions, D. areolatus oviposited in mature eggs and recently hatched larvae of A. obliqua with comparable frequencies. Seven preimaginal stages of D. areolatus were observed during their development, which was completed in 27 days. It is concluded that D. areolatus has the capacity to oviposit in embryo eggs and neonate larvae of A. obliqua and that its first-instar larvae (with three distinct sizes) are capable of synchronizing their development with the development of the host larvae. This finding represents the first report of a native parasitoid attacking eggs or neonate larvae of a tephritid in the Neotropics. The implications of this finding are discussed within the context of the competitive interactions of this species with other parasitoid species under sympatric conditions, as well as the relevance for developing laboratory rearing methods for biological control purposes.
