Anastrepha cruzi was described in 1934, from a specimen without an abdomen. The holotype is the only known record for this species, collected in the Brazilian Amazon Rainforest (location unknown). However, during fruit fly surveys with McPhail-type traps on the campus of the Federal University of Amazonas in Manaus (state of Amazonas), two females...

We analysed the influence of laboratory domestication, under relaxed conditions, on the courtship behaviour of the fruit fly species Anastrepha obliqua, an important agricultural pest. We compared the temporal patterns of pheromone emission (Calling behaviour) and the frequencies and sequences of the courtship behavioural units of males of a labora...

Anastrepha fraterculus (Wiedemann) and A. obliqua (Macquart) are important pests of fruit crops. In Brazil, these species cause damage to fruit growing in the South (annual average temperature of 20.9 °C) and Northeast (average yearly temperature of 24 °C). We evaluated the effect of temperature on the viability and development time of A. fratercul...

Anastrepha obliqua (Macquart, 1835) (Diptera: Tephritidae) is a species of fruit fly that occurs in the Neotropical region and is associated with 78 host plants. In Brazil, the species is one of the most economically important pests for fruit growers, especially in mango cultivation in the northeast region. Evaluating the oviposition behavior of po...

The scarcity of phytosanitary treatment options for polyphagous pests of the Zeugodacus tau complex poses a quarantine risk for importing countries. Owing to the unresolved taxonomy and a limited number of cold treatment schedules available for this group, we tested whether populations of the Z. tau complex infesting Citrus sinensis differ in their...

Anastrepha dissimilis is currently considered to be widely distributed in Brazil, occurring in 20 of 27 states. However, morphological differences between the holotype (from Plaisance, Haiti) and a paratype (from Pernambuco, Brazil) suggest that the Brazilian specimens are not A. dissimilis, because their aculeus tip is similar to the paratype not...

Various host compounds have been investigated to produce an alternative attractant for monitoring and controlling pest insects. Several studies evidenced that volatile molecules released by coffee and mangoes attracted both male and female Ceratitis capitata (Wiedemann), a significant pest in fruit crops. In this study, we tested the effectiveness...

Phytosanitary irradiation (PI) has been successfully used to disinfest fresh commodities and facilitate international agricultural trade. Critical aspects that may reduce PI efficacy must be considered to ensure the consistency and effectiveness of approved treatment schedules. One factor that can potentially reduce PI efficacy is irradiation under...

Biodiesel fuels are attracting increasing attention worldwide as an environmentally friendly fuel. Despite the numerous advantages of biodiesel compared with diesel, some studies indicate that biodiesel is more susceptible to oxidation and therefore more corrosive to metals. The research indicates that stainless steel, cast iron, galvanized steel,...
