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.

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.

Toxicity of Neonicotinoids toCeratitis CapitataandAnastrepha Fraterculus(Diptera: Tephritidae)The effects of imidacloprid and thiamethoxam againstCeratitis capitata(Wiedemann) andAnastrepha fraterculus(Wiedemann) adults were evaluated under broadcast spray and toxic bait systems in the laboratory. In general, whenC. capitataandA. fraterculuswere sprayed with insecticides, the time required for killing them was inversely proportional to the neonicotinoid concentrations. By cover spray, females and males ofA. fraterculuswere more susceptible to imidacloprid and thiamethoxam thanC. capitata, presenting significantly lower LT50. In the case of imidacloprid bait, no differences at LT50were detected between females or males of both fruit flies or between sexes of respective fruit fly species. In general,C. capitataandA. fraterculusadults died in all the toxic baits up to 7 days after application on citrus leaves in the field. The data emphasize the viability of the use of neonicotinoids for the control of fruit flies.

Anastrepha fraterculus (Wiedemann) and Ceratitis capitata (Wiedemann) are the most commonly found fruit fly species in fruit crops in Brazil. Both polyphagous species show similar host ranges, but specific knowledge regarding the ovipositional preference of either species is scarce. The present study aims to evaluate, in the laboratory, ovipositional behaviours in seven fruit host submitted to infestation by A. fraterculus and C. capitata. Except for C. capitata in Tahiti acid lime, the number of punctures containing eggs exceeded the number of punctures without eggs. The highest values for eggs per puncture were obtained in Fuyu persimmon, for which averages of 4.06 and 50.09 eggs per puncture were deposited by A. fraterculus and C. capitata, respectively. For A. fraterculus, the infestation ranking, based on the number of eggs per puncture from high to low, was Fuyu persimmon > papaya > Tahiti acid lime > carambola > coffee > guava > sweet orange. For C. capitata, the infestation ranking was Fuyu persimmon > carambola > papaya > guava > sweet orange > coffee > Tahiti acid lime. All punctures made to carambola and papaya contained eggs. Sweet orange exhibited the maximum number of punctures of A. fraterculus without egg deposition. The first day of medfly oviposition in Fuyu persimmon resulted in approximately three-fold more eggs per puncture than the second, third, and fourth days.

Fruit bagging is an important strategy to protect fruit against fruit fly (Tephritidae) infestation and pesticide contamination. In laboratory, we compared the forced infestation of guavas by Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann) when wrapping them with non- woven fabric (NWF) bags. The combined repellence and protection effects of white, green, blue and red NWF bags were tested in comparison with un-bagged guavas. Bagged fruit with the NWF tissue stuck to the pericarp were separately exposed to both fruit fly species for 48 hours, with a ratio of 10 females per fruit inside of laboratory cages. In C. capitata, the number of pupae per fruit was significantly higher in the green NWF bags, and the infestation in the other colour bags were similar to the control group (non-bagged). In A. fraterculus, guavas with red NWF bags had significantly higher infestation (205.42 pupae per fruit) than fruit that received the other colour bags White and blue bags were less attractive for oviposition from both fruit fly species. The adherence of the NWF bags to the fruit surface causes egg-laying of fruit flies.

This work was carried out in orchards of guava progenies, and loquat and peach cultivars, in Monte Alegre do Sul, SP, Brazil, in 2002 and 2003. Guavas and loquats were bagged and unbagged bi-weekly and weekly, respectively, for assessment of the infestation period. Peach was only bagged weekly. The assays started when the fruits were at the beginning of development, but still green. Ripe fruits were taken to the laboratory and placed individually into plastic cups. McPhail plastic traps containing torula yeast were hung from January 2002 to January 2004 to assess the fruit fly population in each orchard, but only the Ceratitis capitata population is here discussed. Five tephritid species were reared from the fruits: Anastrepha bistrigata Bezzi, A. fraterculus (Wiedemann), A. obliqua (Macquart), A. sororcula Zucchi, and C. capitata, in addition to six lonchaeid species: Neosilba certa (Walker), N. glaberrima (Wiedemann), N. pendula (Bezzi), N. zadolicha McAlpine and Steyskal, Neosilba sp. 4, and Neosilba sp. 10 (both species are in the process of being described by P. C. Strikis), as well as some unidentified Neosilba species. Ten parasitoid species were obtained from fruit fly puparia, of which five were braconids: Asobara anastrephae (Muesebeck), Doryctobracon areolatus (Szépligeti), D. brasiliensis (Szépligeti), Opius bellus Gahan, and Utetes anastrephae (Viereck), and five figitids: Aganaspis pelleranoi (Brèthes), Dicerataspis grenadensis Ashmead, Lopheucoila anastrephae (Rhower), Leptopilina boulardi (Barbotin, Carlton and Kelner-Pillaut), and Trybliographa infuscata Diaz, Gallardo and Uchôa. Ceratitis capitata showed a seasonal behavior with population density peaking at the second semester of each year. Anastrepha and Neosilba species remained in the orchards throughout both years.

The South American fruit fly, Anastrepha fraterculus (Diptera: Tephritidae) stands out for its polyphagous habit of damaging the production of several fruits in southern Brazil. This study aimed to evaluate the capture efficiency of A. fraterculus using grape juice at different periods of decomposition and aging as well as to test the capture efficiency of the enzymatic hydrolyzed protein Cera Trap® in feijoa crops. The work was conducted in a commercial feijoa orchard in São Joaquim, SC, Brazil during the 2014 growing season. Undiluted Cera Trap®, fresh grape juice and grape juice that had aged for 7 and 14 days were evaluated. All of the treatments with grape juice were used at the recommended concentration of 25 %. McPhail traps were used with 300 mL for each lure. On a weekly basis, the number of adults and the percentage of female fruit flies captured were evaluated, using identification and counting. Cera Trap® was the lure that captured the highest number of fruit flies, with a high percentage of females and with a higher frequency of captures during the season. Cera Trap® also showed the highest number of action thresholds compared to grape juice treatments. The 25 % fresh and aged grape juice showed a low number of captures and a low number of action thresholds. We conclude that fresh and aged grape juice were not effective for capturing and  monitoring A. fraterculus in feijoa orchards. The Cera Trap® lure proves to be an alternative to improve  monitoring of A. fraterculus in orchards in southern Brazil.

Toxic bait is an alternative to manage fruit flies (Tephritidae) in orchards and in wide-area programmes. The mortality caused by different dilutions of spinosad baits on adults of Ceratitis capitata (Wied.) and Anastrepha grandis (Macquart) (Tephritidae) were compared with a hydrolysed protein (BioAnastrepha) and water in laboratory. Females and males of C. capitata and A. grandis were exposed to Success® 0.02CB (GF-120 NF Naturalyte fruit-fly, 0.02% spinosad) diluted in distilled water (v/v) at 1:1.5; 1:4.5; 1:9.0 and 1:18.0. Spinosad dilutions at 1: 1.5 and 1: 4.5 showed similar effects and provided 100% adult mortality 24 hours after exposure to the baits. Anastrepha grandis was more susceptible to spinosad baits than C. capitata. Females of C. capitata were less susceptible to spinosad diluted at 1: 1.5, 1: 4.5 and 1: 90, than C. capitata males and both sexes of A. grandis. The values of lethal times (LT50) varied for the different dilutions of spinosad for both fruit-fly species; however, with different patterns for each species. The LT50 values of the two highest concentrations (1: 1.5, 1: 4.5) of spinosad bait were similar for fruit flies of both sexes of each species, but a significant difference was observed between species, with higher LT50 values for C. capitata. In general, the cumulative mortalities of spinosad baits increased at 240, 360, 480 minutes and 24 hours after exposure. BioAnastrepha was shown to be toxic to both species, especially for A. grandis, killing 82% of females and 72% of males at 24 hours after exposure. Spinosad bait may be used in different dilutions to manage C. capitata and A. grandis, with similar toxicity for the two highest spinosad concentrations.

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.

Eggshell Proteins

The eggshell of two fruit flies of economic importance has been studied by means of light and electron microscopy. The eggshell of the olive fruit fly, Dacus oleae, contains compact endochorion, whereas that of the Mediterranean fruit fly, Ceratitis capitata, exhibits a holey endochorionic layer. The eggshells of both species have an innermost chorionic layer which appears to be crystalline in substructure. The anterior pole in each case contains the micropylar canal but in addition it bears an elaborate "cup" in Dacus oleae. Both species exhibit peroxidase activity in most eggshell layers and, as in the case of Drosophila melanogaster, it is thought that the enzyme causes covalent cross-linking of the eggshell proteins producing a resilin-type configuration with rubberlike properties. The above features are related to specific structural functions of the eggshell during fertilization, oviposition, and respiration of the embryo. Biochemical analysis has revealed that the two species have very few eggshell proteins that are similar in molecular weight.
