Phylogeography of the Invasive Fruit Fly Species Drew & Hancock (Diptera: Tephritidae) in South America.

The carambola fruit fly, Drew & Hancock, is native to Southeast Asia, infests about 150 plant species, and is considered a quarantine pest insect in several regions of the world. has invaded Suriname, French Guyana, and northern Brazil. In Brazil, it was first recorded in 1996 and has been restricted to the states of Amapá and Roraima due to official control efforts of the Ministry of Agriculture and Food Supply (Ministério da Agricultura e Pecuária-MAPA).

Viral Diagnosis in Psittacine Birds: A Scientometric and Systematic Review of 47 Years.

The first reports of viruses in psittacine birds date back to the early 1970s. Here, we elucidate the differences among these previous studies and the advances achieved. The objective of this study was to carry out a comprehensive review using both scientometric and systematic methods to analyze the evolution of published studies on viruses in psittacine birds up to 2022.

The genus Steindachner, 1867 currently comprises 29 nominal species, some of which are suggested to be cryptic species complexes. The present study was carried out with specimens of the "" clade that encompasses three taxa distributed in the Atlantic Forest biome: Almeida et Angulo, 2006, sp. L.

Predicting the Invasion Risk by Anastrepha sororcula (Diptera: Tephritidae) in Distinct Geographic Regions.

The movement of endemic fruit flies to new habitats represents a major biological and economic threat. Anastrepha sororcula Zucchi, 1979 is widely distributed in Brazil and also in Colombia, Ecuador, and Paraguay. Here, we present the potential distribution of A.

Fertility life table and biology of (Hymenoptera: Eulophidae) in the larvae of (Diptera: Tephritidae).

Tetrastichus giffardianus is a gregarious koinobiont endoparasitoid of tephritids, including Ceratitis capitata, which is one of the most important fruit pests worldwide. The objective of this study was to evaluate the effect of constant temperatures on the biology and development of the egg-adult period of T. giffardianus in larvae/pupae of C.

Not endemic after all: Imparipecten Freeman, 1961 (Diptera: Chironomidae) described from the Neotropical Region.

Imparipecten, a previously monotypic genus, was considered endemic to Australia. Here, we report Imparipecten from the Neotropical region for the first time and describe Imparipecten sychnacanthus sp. n.

On the identity of Adelophryne pachydactyla Hoogmoed, Borges, and Cascon, 1994 (Brachycephaloidea: Eleutherodactylidae).

The use of molecular data for documenting biodiversity has become more common over time as larger datasets can be generated faster. Nevertheless, studies addressing phenotypical data have not become as common. As a collateral effect, many samples used in molecular studies are assigned to a species without checking phenomic characters of the vouchers.

Genetic Characterization of Some Neoponera (Hymenoptera: Formicidae) Populations Within the foetida Species Complex.

The foetida species complex comprises 13 Neotropical species in the ant genus Neoponera. Neoponera villosa Fabricius (1804) , Neoponera inversa Smith (1858), Neoponera bactronica Fernandes, Oliveira & Delabie (2013), and Neoponera curvinodis (Forel, 1899) have had an ambiguous taxonomic status for more than two decades. In southern Bahia, Brazil, these four species are frequently found in sympatry.

Phylogeography and population diversity of Simulium hirtipupa Lutz (Diptera: Simuliidae) based on mitochondrial COI sequences.

High morphological homogeneity and cryptic speciation may cause the diversity within Simuliidae to be underestimated. Recent molecular studies on population genetics and phylogeography have contributed to reveal which factors influenced the diversity within this group. This study aimed at examining the genetic diversity of Simulium hirtipupa Lutz, 1910 in populations from the biomes Caatinga, Cerrado, and Atlantic Forest.

Identifying Anastrepha (Diptera; Tephritidae) Species Using DNA Barcodes.

Molecular identification of fruit flies in the genus Anastrepha (Diptera; Tephritidae) is important to support plant pest exclusion, suppression, and outbreak eradication. Morphological methods of identification of this economically important genus are often not sufficient to identify species when detected as immature life stages. DNA barcoding a segment of the mitochondrial cytochrome oxidase I gene has been proposed as a method to identify pests in the genus.

Relevant genetic differentiation among Brazilian populations of Anastrepha fraterculus (Diptera, Tephritidae).

We used a population genetic approach to detect the presence of genetic diversity among six populations of Anastrepha fraterculus across Brazil. To this aim, we used Simple Sequence Repeat (SSR) markers, which may capture the presence of differentiative processes across the genome in distinct populations. Spatial analyses of molecular variance were used to identify groups of populations that are both genetically and geographically homogeneous while also being maximally differentiated from each other.

First description of the karyotype of a eucharitid wasp (Hymenoptera, Chalcidoidea, Eucharitidae).

The haploid karyotype of Kapala sp. (Eucharitidae), a parasite of the Neotropical ant Dinoponera lucida Emery, 1901 (Hymenoptera, Formicidae), is reported for the first time. It consists of four metacentric chromosomes.

Numerical and structural chromosome variation in the swarm-founding wasp Metapolybia decorata Gribodo 1896 (Hymenoptera, Vespidae).

The Neotropical Polistinae wasps are diverse in taxonomy, social behavior, and nesting founding characteristics. Although some species in this group have been used as models for studies on wasp's biology, they are poorly known in terms of cytogenetics. Here we reported an intraspecific numerical-structural chromosome variation in the swarm-founding wasp Metapolybia decorata from the Brazilian Atlantic Rainforest using conventional and molecular cytogenetic techniques.

Molecular characterization of constitutive heterochromatin in three species of Trypoxylon (Hymenoptera: Crabronidae: Trypoxylini) by CMA3/DAPI staining.

Previous cytogenetic analyses in Trypoxylon Latreille, 1796 have been basically restricted to C-banding. In the present study, base-specific CMA3 and DAPI fluorochrome staining were used to characterize the constitutive heterochromatin in three Trypoxylon species. The heterochromatin was GC-rich in all the species studied; however, in Trypoxylon nitidum F.

Diversity of Anastrepha spp. (Diptera: Tephritidae) and associated braconid parasitoids from native and exotic hosts in southeastern Bahia, Brazil.

We documented fruit fly-host associations and infestation rates over 5 yr in the state of Bahia, Brazil, by systematically collecting native and introduced fruits in backyard and commercial orchards, experimental stations, and patches of native vegetation. Fruit were collected in multiple sites in the southern and southernmost regions of Bahia. A total of 942.

Faunistic analysis of Anastrepha spp. (Diptera: Tephritidae) on a guava orchard under organic management in the municipality of Una, Bahia, Brazil.

We carried out a study to characterize fruit fly populations on an organic guava orchard (Psidium guajava cv. Paluma) in the municipality of Una, southern region of the state of Bahia, Brazil, using faunistic analysis of the adult fruit fly specimens captured in McPhail traps from January 2004 through March 2007. A total of 22,673 specimens of Anastrepha (15,306 females and 7,367 males) were captured.

Karyotype, heterochromatin distribution and meiosis of Zabrotes subfasciatus (Bohemann) (Coleoptera: Chrysomelidae, Bruchinae).

Zabrotes subfasciatus (Boh.) has been extensively studied in its agronomic and biochemical aspects due to its importance as a damaging insect to leguminous grains during storage. The few cytogenetic studies published on this species yielded conflicting results.

Recent Mediterranean fruit fly (Diptera: Tephritidae) infestations in Florida--a genetic perspective.

Microsatellite and mitochondrial DNA (mtDNA) variability data were used to study infestations of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) in Florida in 1997 and 1998. A total of 132 flies collected in monitoring traps or as larvae removed from fruit were examined at three polymorphic mtDNA restriction sites and two microsatellite loci. All of the flies sampled in Florida in 1997 displayed the mitochondrial AAB haplotype and represent a novel introduction of Mediterranean fruit flies into the state.
