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 present study analyzed the chemical composition of Juniperus foetidissima Willd. essential oils (EOs) and evaluated their attractancy and toxicity to two agriculturally important tephritid fruit flies. The composition of hydrodistilled EOs obtained from leaves (JFLEO) and fruits (JFFEO) of J. foetidissima was analyzed by GC–FID and GC–MS. The main compounds were α-pinene (45%) and cedrol (18%) in the JFLEO and α-pinene (42%), α-thujone (12%), and β-thujone (25%) in the JFFEO. In behavioral bioassays of the male Mediterranean fruit fly, Ceratitis capitata (Wiedemann), both JFLEO and JFFEO showed strong attraction comparable to that observed with two positive controls, Melaleuca alternifolia and Tetradenia riparia EOs. In topical bioassays of the female Caribbean fruit fly, Anastrepha suspensa (Loew), the toxicity of JFFEO was two-fold higher than that of JFLEO, with the LD50 values being 10.46 and 22.07 µg/µL, respectively. This could be due to differences in chemical components between JFLEO and JFFEO. The JFFEO was dominated by 48% monoterpene hydrocarbons (MH) and 46% oxygenated monoterpenes (OM), while JFLEO consisted of 57% MH, 18% OM, and 20% oxygenated sesquiterpenes (OS). This is the first study to evaluate the attractancy and toxicity of J. foetidissima EOs to tephritid fruit flies. Our results indicate that JFFEO has the potential for application to the management of pest tephritid species, and further investigation is warranted.

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.

Since 1954, when the first tropical tephritid fruit fly was detected in California, a total of 17 species in four genera and 11 386 individuals (adults/larvae) have been detected in the state at more than 3348 locations in 330 cities. We conclude from spatial mapping analyses of historical capture patterns and modelling that, despite the 250+ emergency eradication projects that have been directed against these pests by state and federal agencies, a minimum of five and as many as nine or more tephritid species are established and widespread, including the Mediterranean, Mexican and oriental fruit flies, and possibly the peach, guava and melon fruit flies. We outline and discuss the evidence for our conclusions, with particular attention to the incremental, chronic and insidious nature of the invasion, which involves ultra-small, barely detectable populations. We finish by considering the implications of our results for invasion biology and for science-based invasion policy.

Significant Difference

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 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.

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.

This study evaluated the effect of initial pH values of 4.5, 6.5 and 8.5 of the attractant (protein bait) Milhocina® and borax (sodium borate) in the field, on the capture of fruit flies in McPhail traps, using 1, 2, 4 and 8 traps per hectare, in order to estimate control thresholds in a Hamlin orange grove in the central region of the state of São Paulo. The most abundant fruit fly species was Ceratitis capitata, comprising almost 99% of the fruit flies captured, of which 80% were females. The largest captures of C. capitata were found in traps baited with Milhocina® and borax at pH 8.5. Captures per trap for the four densities were similar, indicating that the population can be estimated with one trap per hectare in areas with high populations. It was found positive relationships between captures of C. capitata and the number of Hamlin oranges damaged, 2 and 3 weeks after capture. It was obtained equations that correlate captures and damage levels which can be used to estimate control thresholds. The average loss caused in Hamlin orange fruits by C. capitata was 2.5 tons per hectare or 7.5% of production.

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.
