ABSTRACT: The aim of the present study was to investigate the parasitism of two fruit fly species by different Diachasmimorpha longicaudata strains. Females of two parasitoid strains were reared on Ceratitis capitata or Anastrepha fraterculus that were conditioned in adapted containers. Individual parasitoids were offered 20 larvae for 1 h, using no-choice (20 C. capitata or 20 A. fraterculus) or free-choice (10 of each species) assays. Parasitism was verified by counting scars, and the pupae were classified as non-parasitized (no scars), parasitized (one scar), or superparasitized (multiple scars). Parasitism intensity was compared by evaluating the proportions of non-parasitized, parasitized, and superparasitized larvae. Parasitism intensity and scar frequency were analyzed as functions of host species and parasitoid strain, using chi-square tests. In the non-choice tests, females of both parasitoid strains parasitized the larvae, regardless of host species. However, when the parasitoids had a choice, they preferred to superparasitize A. fraterculus larvae, which are larger than C. capitata larvae. In addition, the female parasitoids parasitized most of the host larvae, regardless of parasitoid strain or host species. However, the frequency of non-parasitized pupae was higher when the offered host species was different from the one in which the parasitoid was reared, and the frequency of superparasitized pupae was higher when the offered host species was the same as the one in which the parasitoid was reared.

Abstract: The objective of this work was to assess the lethal concentration and lethal time (LC and LT) of spinosad and spinetoram, combined with different food lures, and their residual effects on South American fruit fly (Anastrepha fraterculus). The toxic baits were offered in eight concentrations (2, 6, 14, 35, 84, 204, 495, and 1,200 mg L-1), combined with the following food lures: 7% sugarcane molasses, 3% Biofruit, 1.5% CeraTrap, 1.25% Flyral, 3% Samaritá Bait, and 3% Samaritá Tradicional; diluted food lures in water were used as controls. The residual effect of the formulations at 96 mg L-1 concentration were evaluated for 21 days and were compared with that of the commercial bait Success 0.02 CB. Both insecticides were toxic to adults of A. fraterculus, and mortality varied with the food lure used. The LC50and LT50ranged from 15.19 to 318.86 mg L-1and from 11.43 to 85.93 hours, respectively. Spinosad was 2 to 36 times as toxic as spinetoram when combined with different hydrolyzed proteins. Toxic baits formulated with spinosad and spinetoram (96 mg L-1) caused mortality equivalent to the one by Success 0.02 CB (90.2%), when assessed on the day of application. Toxic baits formulated with 3% Biofruit + spinosad and 3% Samaritá Bait + spinetoram are effective for managingA. fraterculusand provide up to seven days of residual effect in the absence of rain; however, only Success 0.02 CB caused more than 80% mortality for up to 21 days.

ABSTRACT The objective of this study was to characterize, through faunistic indices, the populations of fruit flies in the Brejo Paraibano microregion and analyze whether these populations are similar to one another. The study was conducted in eight municipalities located in the Agreste Paraibano mesoregion and Brejo Paraibano microregion, Paraíba state, Brazil, where two rural properties of each municipality were selected, georeferenced and identified according to the diversity criterion of fruit species. Each municipality was assumed to have a population of fruit flies with its own characteristics, determined by the faunistic indices of frequency, constancy, dominance, Shannon-Wiener and Margalef diversity indices, as well as evenness. 3.159 specimens of fruit flies were captured, of which 85.57% belonged to the genus Anastrepha and 14.43% to the genus Ceratitis. 11 species of fruit flies were captured in the traps. Anastrepha fraterculus was the most frequent, dominant and constant species, being present in all locations; followed by A. obliqua, A. sororcula and Ceratitis capitata. The studied municipalities have a similarity of 54%, which indicates a high similarity between the areas. Most species captured in the present study occur at low population frequency.

ABSTRACT: The aim of this study was to know and assess natural infestation of frugivorous flies (Diptera: Tephritidae and Lonchaeidae) and their parasitoids in Surinam cherry fruits. The survey was conducted in an organic orchard, located in the municipality of Maceió, Alagoas. From October 2010 to January 2011, mature green, half-ripe and ripe Surinam cherry were collected. Infestation index was higher for mature green and half-ripe fruits. Five species of frugivorous flies were identified: Anastrepha fraterculus , Anastrepha obliqua , Anastrepha sororcul , Ceratitis capitata (Diptera: Tephritidae), and Neosilba pendula (Diptera: Lonchaeidae). It were identified the parasitoids: Doryctobracon areolatus , Opius bellus, Utetes anastrephae and Asobara anastrephae (Hymenoptera: Braconidae), being D. areolatus with highest percentage of parasitism in all maturation stages. N . pendula was recorded in Brasil associated to Eugenia uniflora L. (Myrtaceae). O . bellus , U . anastrephae and A . anastrephae were also recorded for the first time in the State of Alagoas. Mature green and half-ripe Surinam cherries are the most fruit fly infested, and the parasitism rate is higher in half-ripe and ripe fruits.

Abstract Many parasitoid species discriminate already parasitized hosts, thus avoiding larval competition. However, females incur in superparasitism under certain circumstances. Superparasitism is commonly observed in the artificial rearing of the parasitoid Diachasmimorpha longicaudata, yet host discrimination has been previously suggested in this species. Here, we addressed host discrimination in virgin D. longicaudata females in a comprehensive way by means of direct and indirect methods, using Ceratitis capitata and Anastrepha fraterculus which are major fruit fly pests in South America. Direct methods relied on the description of the foraging behaviour of females in arenas with parasitized and non-parasitized host larvae. In the indirect methods, healthy larvae were offered to single females and the egg distributions were compared to a random distribution. We found that D. longicaudata was able to recognize parasitized host from both host species, taking 24 h since a first parasitization for A. fraterculus and 48 h for C. capitata. Indirect methods showed females with different behaviours for both host species: complete discrimination, non-random (with superparasitism), and random distributions. A larger percentage of females reared and tested on A. fraterculus incurred in superparasitism, probably associated with higher fecundity. In sum, we found strong evidence of host discrimination in D. longicaudata, detecting behavioural variability associated with the host species, the time since the first parasitization and the fecundity of the females.

Abstract The host status of sweet granadilla (Passifflora ligularis Juss.) to Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann) in Peru was determined. Experiments were conducted in Pasco (Peru) in four different orchards, over 2 yr (2016 and 2017), two orchards per year. Choice (granadilla plus natural host) and no-choice foraging behavior trials were conducted using sleeves under field conditions, and forced infestation was examined in laboratory cages, with five females per fruit. The development time of C. capitata was determined, and the oviposition behavior of C. capitata and A. fraterculus was examined. Three fruit maturity stages of intact (n = 1,320) and punctured (n = 1,320) granadilla fruits were examined. Adult C. capitata (n = 4,418) and A. fraterculus (n = 2,484) were trapped in the orchards, and commercial granadilla fruits (n = 1,940) sampled and dissected. Fruit fly infestation was not found in any intact granadilla fruits. Larvae and pupae were found inside punctured granadilla only in fruits broken after 20 d, and adults only emerged when those pupae were removed from the fruit. Ceratitis capitata development time was longer in punctured granadilla than that in host fruit. In the oviposition test, A. fraterculus and C. capitata did not lay eggs in intact granadilla, and C. capitata laid eggs in punctured fruits but larvae were not found. Because of the resistance mechanisms of the pericarp, commercial fruits of Passiflora ligularis are not a natural host of C. capitata and A. fraterculus in Peru.

The Relationship

Abstract Fruit flies (Diptera: Tephritidae) represent a threat to fruit growing worldwide, mainly the citrus culture, however, biological studies show that fruit flies are not perfectly adapted to this host. This study investigated oviposition of Anastrepha fraterculus (Wiedemann, 1830) and Ceratitis capitata (Wiedemann, 1824) and its relation with the pericarp of citrus fruits. We evaluated the relationship between depth of oviposition of A. fraterculus and C. capitata and epicarp thickness of orange [Citrus sinensis (L.) Osbeck)] ‘Navelina’ and tangerine [C. reticulata (L.)] ‘Clemenules’ and the influence of fruit mesocarp of tangerine ‘Clemenules’ on oviposition of these species. The study was conducted under controlled conditions of temperature (25 ± 2 °C), relative humidity (70 ± 10% RH) and photophase (12 h). A. fraterculus and C. capitata laid their eggs in the flavedo region of orange ‘Navelina’ and between the albedo and flavedo of tangerine ‘Clemenules’. When fruits with mesocarp exposed were offered, there was no oviposition by both fruit fly species. The results show that epicarp thickness of citrus fruits did not influence oviposition of A. fraterculus and C. capitata as oviposition did not occur only in the presence of the mesocarp, suggesting that other factors are involved in oviposition of these species.

The aim of this study was to evaluate the adulticidal effects of green coffee oil (GCO) and roasted coffee oil (RCO) on two species of fruit flies (Tephritidae) include Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann). Adult flies of both species were exposed to GCO and RCO at 2%, 3%, and 4% dilutions in water under Potter spray tower. In general, exposure to GCO and RCO at the three dilutions resulted in higher numbers of dead adults of both species compared to the control populations. The mortalities increased substantially between 60–90 minutes after initial exposure. The 2% GCO dilution reached a maximum of 77.0% corrected mortality of A. fraterculus at 360 minutes. In general, the toxic effect of coffee oils occurred more rapidly in C. capitata than in A. fraterculus. GCO (2% and 3%) and RCO (2%) showed promising results for fruit fly management.

AbstractMcPhail traps baited with hydrolysed protein and borax to trap mainly female fruit flies, Jackson traps baited with trimedlure to attract male Ceratitis capitata Wiedemann, and Jackson traps baited with cuelure and methyl eugenol to trap Bactrocera spp., were hung in fruit trees at 50 sites and serviced weekly from June, 1994 to March, 1995, over an area of 350 km2 in Nicaragua. Samples of fruit were collected and kept separately to rear adult fruit flies and their hymenopterous parasitoids from known host plants. No Bactrocera spp. was trapped or reared from fruit at any site. Ceratitis capitata was caught in high numbers in McPhail and Jackson traps at nearly all sites in the dry season, attacking coffee berries and fruit of Citrus species. Toxotrypana curvicauda Gerstaecker was attracted to the food lure McPhail traps in low numbers and was widespread throughout the year, attacking papaya (Caricaceae). Of 29 Anastrepha species known to occur south of Mexico and north of Panama, ten were found during the study, occurring mainly in the rainy season; only two of them were trapped frequently and reared from collected fruit. Anastrepha obliqua Macquart proved to be the second most abundant fruit fly species, with a population peak from June to October when its preferred host plants Mangifera indica, Spondias mombin (Anacardiaceae) and Psidium friedrichsthalianum (Myrtaceae) were ripening. Anastrepha striata Schiner, trapped at 45 sites, occurred from June to November, attacking P. friedrichsthalianum and P. guajava. Sampled fruit of a further eight species in seven families were not attacked by tephritid flies. Parasitism by introduced braconid Diachasmimorpha longicaudata (Ashmead) was very low (3.7% in C. capitata, 2.7% in A. obliqua and 5.3% in A. striata).
