“…Consequently, new augmentative area-wide releases of the D. longicaudata , mass-reared, have been carried out by air or from the ground in different Mexican states [ 14 , 15 , 222 ]. Releases of D. longicaudata have been continuously focused on wild areas and backyard orchards to prevent fruit fly dispersion into commercial crops, which has caused substantial reductions in numbers of Anastrepha adults [ 56 , 137 , 218 , 224 , 225 ]. However, despite the good outcomes achieved with D. longicaudata , the Mexican National Program against Anastrepha spp.…”

Biological control has been the most commonly researched control tactic within fruit fly management programs. For the first time, a review is carried out covering parasitoids and predators of fruit flies (Tephritidae) from the Americas and Hawaii, presenting the main biological control programs in this region. In this work, 31 species of fruit flies of economic importance are considered in the genera Anastrepha (11), Rhagoletis (14), Bactrocera (4), Ceratitis (1), and Zeugodacus (1). In this study, a total of 79 parasitoid species of fruit flies of economic importance are listed and, from these, 50 are native and 29 are introduced. A total of 56 species of fruit fly predators occur in the Americas and Hawaii.

“…One of the main tools with which to achieve efficient mass rearing of fruit fly parasitoids is the use of irradiated hosts (Hendrichs et al, 2009). This facilitates the processes of production and the release of the natural enemy into the field since no adult emergence takes place from the irradiated hosts (Cancino et al, 2012(Cancino et al, , 2016.…”

Doryctobracon areolatus is a native parasitoid of the Neotropical region that presents the highest percentages of natural parasitism of fruit flies of the genus Anastrepha. In the Moscafrut Program SADER-SENASICA, located in Metapa de Domínguez, Chiapas, Mexico, a laboratory colony of this species is maintained on Anastrepha ludens, the Mexican fruit fly, with the aim to scale the production of the parasitoid up to massive levels. In order to eliminate unwanted emergence of adult flies during the rearing process, this study evaluated the effect of irradiation (at doses of 20, 30, 40, and 50 Gy) applied to eggs, and first and second instar larvae of A. ludens; all irradiated stages were subsequently exposed as second instar larvae to adult females of D. areolatus. Irradiation did not affect the eclosion of A. ludens eggs but, at doses of 40 and 50 Gy, it did cause delayed larval development and pupation, as well as lower larval weight. Adult fly emergence was suppressed at all doses, except in eggs irradiated at 20 Gy. Doses of 20 and 30 Gy applied to the eggs and larvae did not affect the emergence, survival, fecundity or flight ability of the emerged parasitoids, but the second instar larvae were easily handled during the rearing process. Our results suggest that D. areolatus can be successfully produced in second instar larvae of A. ludens irradiated at 30 Gy.

“…This wasp has been successfully used in the control of flies of the genus Anastrepha , where up to 50% of parasitism has been obtained with the application of augmentative releases (Siviniski, 1996; Montoya et al, 2000, 2007; Montoya & Cancino, 2004). The efficacy of augmentative biological control depends on efficient pre‐release packing and also on adequate release methods that preserve insects in healthy conditions (Cancino et al, 2017). Terrestrial massive releases of D. longicaudata have been performed using special containers (Montoya et al, 2012; Cancino et al, 2017).…”

“…The efficacy of augmentative biological control depends on efficient pre‐release packing and also on adequate release methods that preserve insects in healthy conditions (Cancino et al, 2017). Terrestrial massive releases of D. longicaudata have been performed using special containers (Montoya et al, 2012; Cancino et al, 2017). One novel strategy is the ‘chilled adult’ technique, which has improved general parasitoid viability by inducing a total stupor during packaging, a strategy that facilitates the managing of aerially released parasitoids (Sivinski et al, 2000; Baeza et al, 2002; Ruiz et al, 2009; Montoya et al, 2012).…”

“…The advantages of aerial releases include an efficient distribution, a short operational time, and reduced resource costs. However, during the pre‐release period (5–7 days) after emergence, D. longicaudata requires conditions and food to mature and copulate because females are synovigenic (eggs mature during their life) (Cancino et al, 2017). Thus, some factors such as overcrowding, which occurs in emergence cages, can cause irreversible stress with a consequent reduction in the host‐searching ability and female fecundity (Cancino et al, 2020).…”

Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) is a solitary parasitoid used in augmentative releases to control Tephritidae (Diptera) fruit flies of economic importance. Pre-release process includes packing adult parasitoids in cages at high densities and expose them to a temperature of 2 AE 2°C during 105 min. In this process, females' antennae may be damaged resulting in a reduction in their host-searching ability and fecundity. Here we measured, for five consecutive days after chilling, the searching ability and fecundity of parasitoids with damaged (D) and undamaged (ND) antennae compared with parasitoids that were not chilled. Female individual responses to fruit infested by Anastrepha spp. was determined in an olfactometer. Latency in the response and latency in making a choice were recorded. Additionally, groups of 30 females were used to measure their ability to find hosts in infested fruit in the laboratory. Fecundity was determined by using artificial oviposition units with Anastrepha ludens (Loew) larvae. In the olfactometer test, ND had lower response than control females during the 1st and 2nd days after chilling. However, no difference in the response was observed between ND and D and the control females on the 5th day. Additionally, chilled females showed a longer latency of response to infested fruit than females of the control treatment when tested in groups. However, after a 24-48 h period, no difference between D and ND and control females was observed. Our results showed similar searching ability and fecundity among parasitoids of the three tested conditions at individual and at group levels. We conclude that pre-release chilling reduces female searching ability only for the first 1-2 days after chilling.
