| O potencial lesivo ao DNA que alguns contaminantes de origem antrópica podem desempenhar, evidencia o risco proporcionado aos ecossistemas aquáticos, quando de alguma forma estes compostos atingem os cursos d?água. O presente estudo apresenta-se como parte do monitoramento das águas da sub-bacia do Rio Siriri (SE), consistindo na verificação da presença de contaminantes com potencial mutagênico e/ou recombinogênico, por meio do Teste SMART em células da asa de Drosophila melanogaster. Foram delimitados quatro sítios para coleta de água, realizada no período correspondente a estação chuvosa do ano de 2013. Linhagens de D.melanogaster portadoras dos genes para pelos mutantes foram submetidas à dois tipos de cruzamentos: Cruzamento padrão (ST) e cruzamento... |

| We determined the influence of resin ducts, sap content, and fruit physicochemical features of four mango cultivars (Criollo, Manila, Ataulfo, and Tommy Atkins) on their susceptibility to the attack of the two most pestiferous fruit fly species infesting mangoes in Mexico: Anastrepha ludens (Loew) and Anastrepha obliqua (Macquart). We performed three studies: 1) analysis of resin ducts in mango fruit exocarp to determine the density and area occupied by resin ducts in each mango cultivar, 2) assessment of mango physicochemical features including fruit sap content, and 3) a forced infestation trial under field conditions using enclosed fruit-bearing branches to expose mangoes to gravid A. ludens or A. obliqua females. Infestation rates, development time... |

| The carambola fruit fly, Bactrocera carambolae Drew & Hancock is native to Southeast Asia, infests about 150 plant species and is considered a quarantine pest insect in the Caribbean region. B. carambolae 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 under official control. This is the first study to estimate genetic structure and diversity of South American populations of B. carambolae. Methods: A total of 116 individuals from 11 localities in Brazil and seven in Suriname were analyzed. Additional sequences available at GenBank from Indonesia (Lampung) and Thailand (San Pa Tong and Muang District) were also used in the analysis. We sequenced a... |

| Anastrepha obliqua (Macquart), the West Indian fruit fly, is the second most polyphagous species within the genus in Brazil and therefore one of the most economically important pest species. It infests an extensive range of hosts, at least 60 species. Anastrepha obliqua ranges from northern Mexico to southern Brazil also including the Caribbean Islands. Methods: We sequenced a fragment of the mitochondrial gene COI to estimate population structure and genetic diversity of A. obliqua geographic collections in Brazil. Results: A total of 153 specimens from the Amazon Forest, Atlantic Rainforest, Cerrado, and Caatinga were analyzed. A total of 20 haplotypes were found. The highest diversity levels were observed in collections from the Amazon Forest. AMOVA and... |

| Introduction: The West Indian fruit fly, Anastrepha obliqua, is a major pest of tropical fruits infesting a wide variety of hosts and in Brazil it is the second most frequent species in the genus. Molecular analyses have shown that A. obliqua does not represent a monophyletic group. This would suggest the need for more detailed studies about population structure. We sequenced a portion of genomic regions COI, ITS, Period and ND6 from A. obliqua gathered in Brazil. Methods: Forty two specimens were collected from fruits and traps from 25 geographic sites in eleven states in Brazil. Methods: DNA was isolated and a partial fragment of each genomic region was amplified by the Polymerase Chain Reaction, then sequenced. The sequences were concatenated in a... |
