“…Although successful in different parts of the world, T. giffardianus failed in São Paulo, possibly because the species did not adapt to the climatic conditions. However, after 60 years with no reports of its presence in Brazil, T. giffardianus was recorded as parasitizing fruit flies at different sites in the Northeast region of the country (ARAUJO et al, 2015;ARAÚJO et al, 2016;COSTA et al, 2005), where a semi-arid climate predominates, similar to the center of origin of this parasitoid. In the northeastern region of Brazil, C. capitata was detected for the first time in 1991 and currently is an important pest, infesting different types of fruits (ARAUJO et al, 2013).…”

“…Due to its beneficial characteristics as a parasitoid of fruit flies, T. giffardianus was transported from West Africa to Hawaii (USA) and later distributed to several Latin American countries for the control of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) (OVRUSKI et al, 2000;PURCELL et al, 1996). In Brazil, T. giffardianus was introduced in the state of São Paulo, Southeast Brazil in 1932 to control C. capitata in citrus orchards (COSTA et al, 2005).…”

Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae) is a gregarious koinobiont endoparasitoid of frugivorous dipterans. In recent years, T. giffardianus has been detected parasitizing Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in different Brazilian semiarid sites. Thus, T. giffardianus has potential to be used in the biological control of C. capitata in semi-arid conditions. However, one of the factors limiting the use of this parasitoid is the lack of detailed information on rearing methods and bioecological aspects. Therefore, the main objectives of this study were to demonstrate a rearing technique for T. giffardianus and to determine the increase in population under laboratory conditions. Specimens of T. giffardianus were obtained in the field through of the collection of fruits infested with C. capitata. The specimens obtained were used to adapt a rearing methodology for T. giffardianus under laboratory conditions. Information on demographic parameters for a T. giffardianus population was obtained using the same methodology. Based on the parameters evaluated, we found that the intrinsic rate of population increase of T. giffardianus was 0.34, the average time of one generation was 19.7 days, the population doubling time was 2.03 days and the finite rate of population increase (?) was 1.41. The demographic parameters obtained demonstrated that, with the rearing technique used, it is possible to maintain populations of T. giffardianus and enable them to multiply under laboratory conditions.

“…Records of T. giffardianus has become frequent in the Northeast of Brazil in recent years, although it has been 60 years without records since its introduction and release in 1937 in the state of São Paulo (Costa, Araújo, Guimarães, Nascimento, & Lasalle, 2005). Tetrastichus giffardianus, D. areolatus, and O. bellus are the only fruit fly parasitoids recorded in the state of Piauí (Araújo et al, 2014(Araújo et al, , 2016. Specimens of O. bellus were obtained associated with A. obliqua in umbu-cajá.…”

“…Currently, 17 species of Anastrepha and C. capitata have been registered in the state of Piauí infesting fruits of carambola (Averrhoa carambola L.) and yellow mombin (Spondias mombin L.) (Zucchi & Moraes, 2008, 2012. Parasitoids of subfamilies Eucoilinae (Figitidae) and Opiinae (Braconidae) are high potential biological control agents to control frugivorous dipterous larvae (Nunes, Nava, Müller, Gonçalves, & Garcia, 2011), but only Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae), Doryctobracon areolatus (Szépligeti), and Opius bellus Gahan (Hymenoptera: Braconidae) have been recorded in fruit flies in the state of Piauí (Araújo, Silva, Querino, Souza, & Soares, 2014;Araújo, Silva, Querino, & Sousa, 2016).…”

“…Tetrastichus giffardianus parasitizes C. capitata on purple mombin in the state of Piauí (first record). Previously, this parasitoid was obtained from puparia of A. obliqua on umbu-cajá in the state (Araújo et al, 2016).

This study aimed to know the species of frugivorous flies (Tephritidae and Lonchaeidae) and their parasitoids associated with fruits in home orchards. It was conducted in the Gurgueia Valley, municipality of Bom Jesus, Piauí, Brazil. Fruit collection was carried out from April to December 2016. A total of 959 fruits (12 kg) belonging to seven fruit species were sampled, such as acerola (Malpighia glabra), carambola (Averrhoa carambola), lime (Citrus aurantifolia), balsam pear (Momordica charantia), cherry of the Rio Grande (Eugenia involucrata), umbu-cajá (Spondias bahiensis), and purple mombin (Spondias purpurea). Only three among these species (acerola, umbu-cajá, and purple mombin) were host, with 2,770 frugivorous flies. Umbu-cajá hosted 316 specimens of Anastrepha obliqua, from which puparia have emerged 84 specimens of Opius bellus and four of Pachycrepoideus vindemmiae. Purple mombin hosted Ceratitis capitata (2,384 specimens), Neosilba pendula (69 specimens), and Anastrepha sp. (one male). Eleven specimens of Tetrastichus giffardianus emerged from the puparia of C. capitata. Acerola hosted only one female of C. capitata and six specimens of N. pendula. Ceratitis capitata and N. pendula were recorded for the first-time infesting fruits of purple mombin in Piauí. Tetrastichus giffardianus parasitizing C. capitata in purple mombin was first recorded in the state of Piauí. Pachycrepoideus vindemmiae is a new record in A. obliqua in umbu-cajá in Brazil.
