“…Studies of bio-ecology and the potential of hymenopterous parasitoids for biological control of fruit flies in Brazil have been increasing in recent decades, for four main reasons: (1) clarification on the identity of fruit fly parasitoids and Ceratitis capitata (Wiedemann), principally in the South region of Brazil [2, 3,4,5]; (3) growing restrictions on application of toxic chemicals for pest control and the increased public awareness of food safety; and (4) effort to preserve biodiversity of agroecosystems, through ecologically friendly strategies, which are aimed at maintaining and increasing the population of natural enemies of pests [6].…”

Fruit-bearing plants in the Brazilian Amazon are mainly attacked by species of Anastrepha, of which about half are endemic to the region. However, tritrophic relations (fly/plant/parasitoid) have only been established for some 25% of the species of Anastrepha in the region. At present, 11 species of hymenopterous parasitoids (Braconidae and Figitidae) have been recorded in the Brazilian Amazon. Parasitoids in general, especially those of the family Braconidae, stand out as the most effective natural enemies of fruit flies of the genus Anastrepha. Doryctobracon areolatus is the most abundant parasitoid and it is associated with the largest number of Anastrepha species in the region. Some fruiting species, for example Bellucia grossularioides (L.) Triana and Geissospermum argenteum Woodson, have been studied aiming at biological control of fruit flies, because they act as reservoirs or multipliers of fruit fly parasitoids. Although research has advanced significantly in the past 20 years, there is a shortage of studies in nearly all states in the region, due to the huge area of the Brazilian Amazon.

“…However, D. areolatus adults were attracted to and fed on all treatment baits offered. Based on the isolated effects of the food attractants, all attractants in the absence of insecticide caused low toxicity (M < 25%) and did not show sublethal effects (reduction of parasitism) on surviving insects after feeding on food attractants when compared to the insects fed the water and 80% honey solution, which was considered the standard for rearing and multiplication of the species in the laboratory (Gonçalves et al 2018).…”

“…At 24 HAE, the surviving adults were fed 80% honey solution until the end of the bioassay. For 10 consecutive days, second instar larvae of A. fraterculus were offered (±10 larvae/female in a mixture with corn flour and wheat fiber diet) (Gonçalves et al 2018). After 7 h of exposure, the larvae were removed and transferred to a cornmeal-based diet to complete larval development.…”

“…In Brazil, several species of fruit fly parasitoids have been reported to occur naturally, such as Doryctobracon areolatus (Szépligeti) (Hymenoptera: Braconidae), D. brasiliensis (Szépligeti) (Hymenoptera: Braconidae), Opius bellus (Gahan) (Hymenoptera: Braconidae), and Aganaspis pelleranoi (Brèthes) (Hymenoptera: Figitidae) (Ovruski et al 2000, Marsaro Júnior et al 2011, Nunes et al 2012). However, the larval parasitoid D. areolatus has been shown to be the most promising natural enemy for the management of A. fraterculus and C. capitata (Marinho et al 2009, Nunes et al 2011, Garcia and Ricalde 2013, Murillo et al 2015, Gonçalves et al 2018). In addition to being a native parasitoid (Zucchi and Moraes 2008), rearing techniques for D. areolatus have already been developed for biological control programs (Gonçalves et al 2018).…”

The use of toxic baits has become one of the main methods of management of fruit flies in Brazil. The application of toxic baits may cause side effects on the native parasitoid Doryctobracon areolatus (Hymenoptera: Braconidae). Based on the results, formulations made from the food attractants 3% Biofruit, 1.5% Ceratrap, 1.25% Flyral, 3% Isca Samaritá, 3% Isca Samaritá Tradicional, and 7% sugarcane molasses associated with the Malathion 1000 EC and the ready-to-use toxic bait Gelsura (containing the active ingredient alpha-cypermethrin) were classified as harmful (class 4) to D. areolatus (mortality > 85% at 96 HAE). In contrast, for toxic baits formulated with insecticide phosmet, the mortality ranged from 38% to 72%, classified as slightly harmful or moderately harmful. However, when phosmet was added to the 3% Samaritá Tradicional bait, the mortality was only 3.9% (class 1—harmless), similar to the toxicity observed for the Success 0.02 CB ready-to-use bait (0.24 g a.i. spinosad/l) (<5% mortality). Although toxic baits were formulated with spinosyn-based insecticides, all toxic bait formulations were classified as harmless or slightly harmful (<50% mortality) to D. areolatus, with the exception of 1.5% Ceratrap + spinetoram and 7% Sugarcane molasses + spinosad (≈ 60% mortality—moderately harmful). In addition, these formulations did not show sublethal effects in reducing the parasitism and emergence rate of the F1 generation of D. areolatus in A. fraterculus larvae. The results serve as a basis for the correct use of toxic food baits without affecting the biological control.

“…Environmental factors affecting the parental generation may determine the production of diapausing offspring (Saunders 1965). In this sense Gonçalves et al (2018) showed that temperature influence the immature development and demographic parameters of a Brazilian population of D. areolatus parasitizing A. fraterculus, but it remains to test whether temperature or other environmental factors affect the frequency of diapause in this species. Our D. areolatus population has been exposed to Anastrepha ludens larvae in guava fruits under laboratory conditions for 23 generations.…”

Doryctobracon areolatus (Szépligeti), a solitary endoparasitoid native to the Neotropics, attacks eggs and early instar larvae of Anastrepha fruit flies, and can enter diapause under tropical and subtropical conditions. We aimed to test if biological attributes, such as size, flight ability, starvation resistance, longevity and fecundity of diapausing individuals differ from those of non-diapausing ones. Parasitoids were obtained from a laboratory colony reared on Anastrepha ludens (Loew) larvae. Parasitized host puparia were sorted in two cohorts according to their diapause condition. Developmental time from egg to adult ranged from 18 to 31 days in non-diapausing parasitoids, and 70 to 278 days for diapausing individuals. Pupal weight and adult measurements were higher in non-diapausing than in diapausing parasitoids. There were no differences in adult longevity, starvation resistance, and emergence between diapausing and non-diapausing wasps. Flight ability and fecundity rates were greater in the non-diapausing than in the diapause cohort. The proportion of female offspring was greater in the non-diapausing cohort (42.5%), whereas in the diapausing cohort the male offspring proportion was greater (62.4%). Both cohorts produced diapause offspring, but the non-diapausing cohort produced more (26.6%) than the diapausing one (9.1%). Maternal age had a significant effect on the proportion of diapause offspring: in 26 to 34 days old non-diapausing females, 78.9% of their offspring entered into diapause. These results confirmed that diapause affects the biological attributes of D. areolatus. The observed differences contribute to better understand the diapause influence on the colonization and rearing process of this species and its use as biocontrol agent.
