“…In addition to our findings, the hypothesis that edaphic characteristics, rather than temperature, constrain the distribution of A. grandis in the state of São Paulo is supported by two recent studies. Based only on a laboratory study of the biology of A. grandis at different temperatures (Bolzan et al, 2017) and the resulting data on its thermal requirements, Silva et al, (2019a) predicted up to 10 generations per year for A. grandis in northeastern Brazil, whereas Lisbôa et al, (2020) predicted that the annual number of generations would be highest (>2) in the north and northeast regions. However, the fly has never been collected in either of these regions (Uchôa & Nic acio, 2010), despite several fruit fly surveys carried out.…”

“…In South America, because of the interest ofmany countries in exportingmelon, watermelon, and other cucurbits, the studies necessary for PRA and classification of A. grandis-free areas began in the mid-1980s (de Cabanilla & Escobar, 1993Aguirre, 1997;Gonzalez & Troncoso, 2007;Guillen & Sanchez, 2007), including Brazil (Araujo et al, 2000). The biology (Silva & Malavasi, 1996;Bolzan et al, 2015Bolzan et al, , 2017, pest-free areas (Nascimento et al, 1993;Malavasi & Zucchi, 2000;Silva et al, 2019a), and regions using systems-approach crop production (Araujo et al, 2009;Montes et al, 2011;Rabelo et al, 2013;Silva et al, 2019b) are well defined. However, the factors limiting the distribution of A. grandis in these regions are still unknown.…”

“…However, both regions have thermal conditions suitable for the development of A. grandis, based on current knowledge of its biology (Bolzan et al, 2015(Bolzan et al, , 2017. In fact, Silva et al (2019a), based on thermal requirements, predicted that A. grandis would occur in the semiarid region of northeastern Brazil, a large region that could be classified as a pest-free area, including two officially registered pestfree areas in the states of Rio Grande do Norte and Cear a. Therefore, temperature cannot be solely responsible for the restricted distribution, and other abiotic factors are probably preventing A. grandis from establishing in certain regions.…”

The South American cucurbit fruit fly, Anastrepha grandis (Macquart) (Diptera: Tephritidae), is an economically important pest of cucurbits and is classified as a quarantine species in many countries. In Brazil, A. grandis has a limited distribution; it is absent from northern and northeastern Brazil and distributed discontinuously in other parts of the country. To indirectly evaluate the influence of climatic and edaphic variables on the occurrence of A. grandis, we used data based on 4 years of cucurbit fruit collections from all mesoregions of the state of São Paulo. Our results show evidence that A. grandis is constrained by a minimum air temperature above 12°C, low (<20°C) and high (>29°C) maximum air temperature, and by low rainfall and relative humidity, occurring at altitudes from 520 to 780 m. More importantly, A. grandis was not collected in central to western São Paulo, where sandy soil and low soil water availability predominate and the climate is hot and dry. Our findings suggest that soil texture and moisture may be limiting factors for pupal survivorship of A. grandis, and consequently edaphic characteristics should be taken into account in studies on its geographical distribution. Based on our results, central to western São Paulo state can potentially be classified as an area of low pest prevalence. Moreover, in countries where cucurbit species are cultivated in such conditions, it is not likely that A. grandis could become established.

Coping with global warming: Adult thermal thresholds in four pestiferous Anastrepha species determined under experimental laboratory conditions and development/survival times of immatures and adults under natural field conditions

et al. 2022

Climate change, particularly global warming, is disturbing biological processes in unexpected ways and forcing us to re-study/reanalyze the effects of varying temperatures, among them extreme ones, on insect functional traits such as lifespan and fecundity/fertility. Here we experimentally tested, under both laboratory and field conditions, the effects of an extreme range of temperatures (5, 10, 15, 20, 30, 40, and 45 °C, and the naturally varying conditions experienced in the field), on survivorship/lifespan, fecundity, and fertility of four pestiferous fruit fly species exhibiting contrasting life histories and belonging to two phylogenetic groups within the genus Anastrepha: A. ludens, A. obliqua, A. striata, and A. serpentina. In the field, we also measured the length of the entire life cycle (egg to adult), and in one species (A. ludens), the effect on the latter of the host plant (mango and grapefruit). Under laboratory conditions, none of the adults, independent of species, could survive a single day when exposed to a constant temperature of 45 °C, but A. striata and A. serpentina females/males survived at the highly contrasting temperatures of 5 and 40 °C at least 7 days. Maximum longevity was achieved in all species at 15 °C (375, 225, 175 and 160 days in A. ludens, A. serpentina, A. striata and A. obliqua females, respectively). Anastrepha ludens layed many eggs until late in life (368 days) at 15 °C, but none eclosed. Eclosion was only observed in all species at 20 and 30 °C. Under natural conditions, flies lived ca. 100 days less than in the laboratory at 15 °C, likely due to the physiological cost of dealing with the highly varying environmental patterns over 24 h (minimum and maximum temperatures and relative humidity of ca. 10–40 °C, and 22–100%, respectively). In the case of A. ludens, the immature’s developmental time was shorter in mango, but adult survival was longer than in grapefruit. We discuss our results considering the physiological processes regulating the traits measured and tie them to the increasing problem of global warming and its hidden effects on the physiology of insects, as well as the ecological and pest management implications.

“…As cucurbitáceas são uma família de grande importância alimentar, possuindo um significativo número de espécies que compõem a rotina alimentar de pessoas e animais em todos os continentes, inclusive no Brasil (Borges et al, 2007). O Brasil é o quarto maior produtor mundial de melancia, que já foi a cucurbitácea de maior importância econômica, principalmente devido ao apelo comercial (FAO 2019), com uma área plantada de aproximadamente de 39.697 ha apenas na região Nordeste e com uma de produção de R$ 775.324 ton (IBGE, 2020) distribuídos principalmente pelo Ceará e pelo Rio Grande do Norte (351.997 ton), que são os que apresentam maior área de produção e maiores volumes de exportações do Brasil (Silva, 2019). Atualmente o melão é principal cucurbitácea exportada, só no Ceará foram realizados negócios que ultrapassaram 41 milhões de dólares na cotação de novembro de 2022.…”

Anastrepha grandis (Diptera: Tephritidae) é uma mosca-das-frutas que causa danos econômicos em cucurbitáceas, como melão e abóbora. A praga possui status de quarentenária em vários países, pois está restrita à América do Sul e é o principal fator limitante à exportação de cucurbitáceas brasileiras. Na região do Jaguaribe-Apodi e no seu entorno (Ceará e Rio Grande do Norte), há uma área livre de A. grandis, reconhecida pelo Ministério da Agricultura e Pecuária (Mapa). Tal condição tem sido mantida devido a uma política de vigilância preconizada pelo Mapa e realizada pelas agências de defesa de ambos os estados. Os frutos de cucurbitáceas brasileiras só podem ser exportados para países que impõem restrições a essa praga se oriundos de áreas livres da praga ou produzidos sob sistema de mitigação de risco. Anastrepha grandis é nativa do Brasil, porém não é encontrada no bioma Caatinga, onde está a grande maioria da área livre da praga. Então, que fatores realmente são limitantes para o estabelecimento da praga em um bioma exótico a ela? Para dar subsídios às medidas de manutenção de áreas livres da praga, esse trabalho apresenta a distribuição geográfica potencial de A. grandis no mundo, com ênfase na área livre nos estados do Ceará e Rio Grande do Norte. A estimativa de potencial distribuição foi feita com a modelagem CLIMEX. Dados de ocorrência e de biologia da espécie foram obtidos da literatura e banco de dados, para definição dos parâmetros e validação do modelo. Mapas indicando as regiões com adequabilidade climática para A. grandis foram gerados com e sem irrigação. O modelo indica que regiões de clima tropical e temperado em todo o globo possuem adequação à praga, sendo que ao se adicionar a irrigação, a adequabilidade aumenta. A maior parte da área livre não é adequada a A. grandis, mesmo sob irrigação, exceto na parte leste, na região de transição entre Caatinga e Mata Atlântica. Assim a adoção de medidas de prevenção de entrada de A. grandis nessas áreas devem ser intensificadas. Palavras-chave: Área Livre de Pragas. Moscas-das-frutas. Cucurbitáceas.
