Holistic Understanding

AbstractTropical fruit flies are considered among the most economically important invasive species detected in temperate areas of the United States and the European Union. Detections often trigger quarantine and eradication programs that are conducted without a holistic understanding of the threat posed. Weather-driven physiologically-based demographic models are used to estimate the geographic range, relative abundance, and threat posed by four tropical tephritid fruit flies (Mediterranean fruit fly, melon fly, oriental fruit fly, and Mexican fruit fly) in North and Central America, and the European-Mediterranean region under extant and climate change weather (RCP8.5 and A1B scenarios). Most temperate areas under tropical fruit fly propagule pressure have not been suitable for establishment, but suitability is predicted to increase in some areas with climate change. To meet this ongoing challenge, investments are needed to collect sound biological data to develop mechanistic models to predict the geographic range and relative abundance of these and other invasive species, and to put eradication policies on a scientific basis.

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.

The lesser pumpkin fly, Dacus ciliatus (Loew), is one of several fruit flies found in Africa and Asia which could be expected to become serious pests of Florida agricultural crops if introduced into this state. This species has not been intercepted in the United States, but prospects are likely for this to occur because of our heavy international traffic. This document is EENY-258 (originally published as DPI Entomology Circular 81), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Guava (Psidium guajava L.) presented prominence among the tropical fruit.  Guava exports are still unimpressive, because of the quarantine pests, among them the fruit flies.  The present research had as objective to evaluate the population fluctuation of fruit flies Anastrepha spp. and the fruits infestation caused in guava accesses cultivated in organic system, and study the possible correlations between this pest and meteorological factors.  To estimate population fluctuation, 20 yellow sticky traps were used.  The reviews were initiated in April 2013, for 378 days.  The traps were kept in the field for the entire duration of the experiment, and they were reviewed every 14 days in most cases, during replacement of traps for new ones.  With the data, simple correlations were calculated between the fruit flies of the genus Anastrepha spp., the temperature, and precipitation.  Nine fruits per accession, at the stage of maturation, were taken to the laboratory and evaluated for fruit fly infestation by the longitudinal cutting of fruit. The averages were compared by the Scott-Knott test at 5% probability.  The genus Anastrepha was found in greater quantity, and there is no correlation between the meteorological factors and population fluctuation of Anastrepha.  Also was found some individuals of the species Ceratitis capitata.  Most of the fruits of the evaluated accesses presented high infestations by fruit flies.  Accesses IAC – 4 – Cica noteworthy for not presenting any infested fruit, without differing from accesses Taquaritinga Comum, both red.  The accesses Torrão de Ouro, Supreme BA, L2P4, and Supreme, also showed low numbers of fruit attacked.

1. Mango fruits infested with fruit fly maggots have no commercial value and could not profitably be shipped to the United States. 2. Sterilization at a temperature of 43°C for eight hours in a circulating atmosphere saturated with moisture kills the eggs, maggots and pupae of the fruit flies that infest mangoes and guavas in Puerto Rico without unfavorably affecting the flavor, appearance or keeping qualities of the fruit if it is afterwards placed in refrigeration. 3. Sterilization does not render marketable mangoes which have already been injured by fruit fly maggots. Such fruit shows the injury and the dead maggots on being cut open, and decays rapidly. 4. Sterilized mangoes from Puerto Rico could safely be allowed into the United States under permit because (1st) only varieties that are not infested would be shipped and (2nd) the fruits would in addition have been submitted to a treatment which renders them free from the pest if they contained it. 5. The varieties that could be sterilized are the Mayagüez mango, the Girón, the Colombo kidney and some of the better ones from Vieques. 6. Since the period of sterilization of eight hours can be reduced to four hours without rendering the treatment less effective in destroying the insect, the margin of safety is very large. 7. Mangoes can be rendered free from fruit fly infestation by sterilization for 8 hours at 43°C piled on trays, crated or wrapped in paper and crated.

Intentional Introduction

The growing movement of people and goods that started in the closing years of the twentieth century has increased the possibility of the accidental or intentional introduction of biohazards that can affect agricultural production in the United States. This study examines the ex ante decision between the deployment of monitoring devices (traps) versus the use of countermeasures to control Mediterranean fruit flies in Florida. To examine this tradeoff, this study outlines a mathematical model to study the effectiveness of traps and the cost of treatment. The empirical results presented in this study indicate that additional parameterization efforts are needed.

AbstractOpiine wasps are parasitoids of dacine fruit flies, the primary horticultural pests of Australia and the South Pacific. A taxonomic synopsis and distribution and host records (44% of which are new) for each of the 15 species of dacine-parasitizing opiine braconids found in the South Pacific is presented. Species dealt with are Diachasmimorpha hageni (Fullaway), D. kraussii (Fullaway), D. longicaudata (Ashmead), D. tryoni (Cameron), Fopius arisanus (Sonan), F. deeralensis (Fullaway), F. ferrari Carmichael & Wharton sp. n., F. illusorius (Fischer) comb. n., F. schlingeri Wharton, Opius froggatti Fullaway, Psyttalia fijiensis (Fullaway), P. muesebecki (Fischer), P. novaguineensis (Szépligeti) and Utetes perkinsi (Fullaway). A potentially undescribed species, which may be a colour morph of F. vandenboschi (Fullaway), is diagnosed but not formally described. Fopius vandenboschi sensu stricto, Diachasmimorpha fullawayi Silvestri, Psyttalia concolor Szépligeti and P. incisi Silvestri have been liberated into the region but are not considered to have established: a brief diagnosis of each is included. Biosteres illusorius Fischer is formally transferred to the genus Fopius. A single opiine specimen reared from a species of Bactrocera (Bulladacus) appears to be Utetes albimanus (Szépligeti), but damage to this specimen and to the holotype (the only previously known specimen) means that this species remains unconfirmed as a fruit fly parasite: a diagnosis of U. cf. albimanus is provided. Psyttalia novaguineensis could not be adequately separated from P. fijiensis using previously published characterizations and further work to resolve this complex is recommended. A key is provided to all taxa.

AbstractMean surface temperatures have increased globally by ~0.7 °C per century since 1900 and 0.16 °C per decade since 1970 (Levinson and Fettig 2014). Most of this warming is believed to result from increases in atmospheric concentrations of greenhouse gases produced by human activity. Temperature increases have been greater in winter than in summer, and there is a tendency for these increases to be manifested mainly by changes in minimum (nighttime low) temperatures (Kukla and Karl 1993). Changes in precipitation patterns have also been observed, but are more variable than those of temperature. Even under conservative emission scenarios, future climatic changes are likely to include further increases in temperature with significant drying (drought) in some regions and increases in the frequency and severity of extreme weather events (IPCC 2007). For example, multimodel means of annual temperature from climate projections predict an increase of 3–9 °C in the United States over the next century combined with reductions in summer precipitation in certain areas (Walsh et al. 2014). These changes will affect invasive species in several ways. Furthermore, climate change may challenge the way we perceive and consider nonnative invasive species, as impacts to some will change and others will remain unaffected; other nonnative species are likely to become invasive; and native species are likely to shift their geographic ranges into novel habitats.

Case Basis

AbstractIn this chapter, we describe current understanding of and identify research gaps on how invasive species directly, and indirectly, affect ecosystem processes. Specifically, we focus on how invasive species can alter the terrestrial carbon, nitrogen, and hydrologic cycles and how changes to these terrestrial cycles cascade to affect water quantity and quality. While invasive species may alter other ecosystem processes, we focus on these due to their importance to policy, to the public, and to their likely interaction with climate change effects. For example, carbon sequestration and surface water supply originating from forests and grasslands (Caldwell et al. 2014) are important policy and public concerns, and drought frequency and intensity will likely increase with climate change (Vose et al. 2016a). Our goal is to draw generalizations rather than provide details on invasive species effects on a case-by-case basis. We do, however, provide case studies for illustration and draw linkages with other chapters that provide detailed coverage to disturbance regimes (Chap. 10.1007/978-3-030-45367-1_5) and types and mechanisms of ecological impact caused by invasive insects (Chap. 10.1007/978-3-030-45367-1_2).
