Oviposition preference and biological performance of Ceratitis capitata in Anacardiaceae, Cactaceae and Vitaceae fruit

Abstract

RESUMO: O objetivo do estudo foi comparar a utilização de frutos de importância econômica e social para o nordeste do Brasil por Ceratitis capitata Wied. (Diptera: Tephritidae) para oviposição, desenvolvimento larval, tamanho e longevidade de adultos. Foram utilizados frutos de manga (Mangifera indica L.), quiabento (Pereskia bahiensis Gürke), palma-forrageira [Opuntia fícus indica (L.) Mill] e uva (Vitis vinifera L.) e moscas procedentes de uma população híbrida de laboratório. Inicialmente, utilizaram-se quatro tratamentos (frutos) e seis repetições, com o oferecimento dos frutos a 10 casais de C. capitata, com posterior (96 horas) contagem de ovos. O segundo teste foi conduzido com seis tratamentos e 10 repetições, oferecendo-se dois tipos de frutos simultaneamente, combinados dois a dois, a 10 casais de C. capitata. O último bioensaio compreendeu quatro tratamentos e seis repetições, sendo oferecidos 20 g de fruto a 20 larvas de primeiro instar de C. capitata. Após seis dias, as larvas foram colocadas em potes plásticos contendo vermiculita até a empupação, quantificando-se: períodos larval e pupal, viabilidade e massa pupal e longevidade e tamanho do adulto. Os dados foram submetidos à análise de variância (ANOVA) pelo Programa R Core Team. Ceratitis capitata oviposita e completa seu ciclo biológico nos quatro hospedeiros estudados, exibindo não preferência para oviposição e baixa performance biológica em frutos de quiabento. Este proporcionou adultos menores e a uva permitiu a menor sobrevivência. As cactáceas palma e quiabento permitem a sobrevivência de C. capitata em laboratório, sendo esse conhecimento relatado pela primeira vez, comprovando que essas espécies podem atuar como hospedeiros alternativos no campo. ABSTRACT:The objective of this study was to compare the use of fruits of great economic and social importance for the northeast of Brazil by Ceratitis capitata Wied. (Diptera: Tephritidae) for oviposition, larval development, size and longevity of adults. Fruits of mango (Mangifera indica L.), quiabento (Pereskia bahiensis Gürke), forage palm [Opuntia fícus indica (L.) Mill] and grape (Vitis vinifera L.) were used, as well as flies from a hybrid laboratory population. Initially, four treatments (fruits) and six replications were used; the fruits were offered to 10 C. capitata couples, with later (96 hours) egg count. The second was conducted with six treatments and 10 replicates, offering two types of fruits simultaneously, combined two to two, to 10 C. capitata couples. The last bioassay comprised four treatments and six replicates, where 20 g of fruit were offered to 20 first-instar C. capitata larvae. After six days, the larvae were placed in plastic pots containing vermiculite until pupation, quantifying larval and pupal periods, viability and pupal mass, besides longevity and adult size. The data were submitted to ANOVA using the R Core Team software. Ceratitis capitata oviposits and completes its biological cycle in the four hosts studied, exhibiting no preference for oviposition and low bi...

Comparative biology of mediterranean fruit fly in star fruit and mango

“…Caatinga, Mossoró, v.37: e11814, 2024 3 of 6 parameters may be related to variations in C. capitata populations, such as the nutritional and physicochemical characteristics of the hosts. In general, the puparium or mass size is an indication of adult size, as observed by Leite et al (2019). No significant difference was observed for larval period length (F-test = 0.05, p˃0.05) between the two types of fruits (Figure 1D).…”

“…According to Plácido-Silva, Zucoloto and Joachim-Bravo (2005), foods with low protein content, such as star fruit, reduce the larval size and, consequently, pupal mass. In general, the puparium or mass size is an indication of adult size (LEITE et al, 2019).…”

“…The experimental design was completely randomized, with two treatments (star fruit and mango) and 20 replications. The biological cycle assessment was performed according to the methodology by Leite et al (2019). Ripe fruits were peeled, cut, had the seeds removed, and portions of 20 g were offered to 20 first-instar larvae of C. capitata (totaling 400 larvae) with up to 3 hours of emergence from the rearing in the laboratory.…”

“…Ceratitis capitata has the adaptive capacity to different hosts and, in the absence of the primary host, uses secondary hosts, favoring its maintenance in the available hosts (LEITE et al, 2019). The Mediterranean fly may have different biological characteristics, which are influenced by the host.…”

Mineral and natural films change the physical–chemical properties of grapes and modulate oviposition behaviour of Ceratitis capitata Wiedemann (Diptera: Tephritidae)

“…Even in inappropriate hosts, in an attempt to leave offspring, fruit flies can oviposit on these substrates (Aluja and Mangan, 2008). In the absence of a primary host, C. capitata searches for an alternative host, such as Opuntia ficus-indica (L.) Mill and Pereskia bahiensis Gürke, to ensure offspring survival, even though they are poorly suited hosts for larval development (Leite et al ., 2017; Leite et al ., 2019).…”
