The current and future potential geographic range of West Indian fruit fly, Anastrepha obliqua (Diptera: Tephritidae)

Abstract

The West Indian fruit fly, Anastrepha obliqua (Macquart), is one of the most important pests throughout the Americas. CLIMEX 3.0 and ArcGIS 9.3 were used to model the current and future potential geographical distribution of this pest. Under current climatic conditions, A. obliqua is predicted to be able to establish throughout much of the tropics and subtropics, including not only North and South America, where it has been reported, but also southern Asia, northeastern Australia and Sub-Saharan Africa. The main factors limiting the pest's range expansion may be cold stress. Climate change expands the potential distribution of A. obliqua poleward as cold stress boundaries recede, but the predicted distribution in northwestern Australia and northern parts of Sub-Saharan Africa will decrease because of heat stress. Considering the widely suitable range for A. obliqua globally and in China, enhanced quarantine and monitoring measures should be implemented in areas that are projected to be suitable for the establishment of the pest under current and future climatic conditions.

Fruit flies (Diptera: Tephritidae) in commercial mango orchards in a semiarid region of Brazil

“…However, the results show that for the semiarid region of Rio Grande do Norte, C. capitata is the most important species since it is common in the region and has been found infesting ripen mangoes. Even though A. obliqua is considered an important mango pest in the tropical America (FU et al, 2014;GUILLÉN et al, 2017) and it has a wide distribution in Brazil, this species has not been a problem in mango orchards in this region of the semiarid. The species A. fraterculus and A. serpentina should not cause great concern as they practically do not occur in the semiarid region (MALAVASI et al, 2000).…”

Changes in the potential distribution of the guava fruit flyAnastrepha striata(Diptera, Tephritidae) during the current and possible future climate scenarios in Colombia

“…The models under climate change scenarios with an increase in temperature ,expanded the geographic area suitably, as evidenced here for A. striata in Colombia (Figure 4). This behavioral response may be evidenced in species limited by low temperatures, where the increase in warmth in the occurrence area may shift the geographical range towards cold regions (Fu et al 2014). Although the presence probability decreased in the Pacific region, it could be the result of climatic effects due to proximity to the coastal zone, where the general climatic conditions are remarkably unstable (Martínez-Ardila et al 2005) It should be noted that the potential distributions of species depend not only on weather conditions but also on dispersal capacity, host availability, and the effects of ecological relationships (Peterson et al 2011).…”

“…The damage caused by A. striata can be devastating; total losses of 90% of the crop have been documented recent decades (Núñez et al 2004). Management plans, including the potential distribution of fruit flies, have been considered in the United States (Sequeira et al 2001), Europe (Godefroid et al 2015), and globally for Anastrepha obliqua (Fu et al 2014). In Colombia, integrated pest management against fruit flies has been proposed by governmental institutions (Instituto Colombiano de Agropecuario -ICA); however, none of these initiatives have included potential distribution or spatial distribution modeling (ICA 2016).…”

Quality control and characterization of the testicles and ovaries of irradiated Anastrepha obliqua from Brazil

“…The fruit flies of the genus Anastrepha Schiner (1868) (Diptera: Tephritidae) cause great damage to fruit production in America (Malavasi and Zucchi, 2000). In Brazil one of the least studied species of economic and quarantine importance is the West Indian fruit fly, Anastrepha obliqua Macquart, found in almost all states, especially in Amazonas and Maranhão, with approximately 70 registered hosts (Fu et al, 2014).…”
