Oviposition Preference and Offspring Performance of the Oriental Fruit Fly Bactrocera Dorsalis (Diptera, Tephritidae) on Eight Host Plants

Abstract

The oriental fruit fly, Bactrocera dorsalis, is one of the most destructive pests of tropical and subtropical fruit crops. The aim of this study was to assess the effect of 8 fruit species on oviposition preference and the offspring performance of B. dorsalis.Total soluble solids and pH of fruits were determined by using respectively a refractometer and pH meter.The oviposition preference was evaluated in choice and nochoice tests respectively inside1 by 0.6 by 0.6 m and 30 by 30 by 30 cm cages at laboratory conditions.The offspring performance was assessed by infesting the fruits with freshly laid eggs and followed until the emergence of adults.The values of total soluble solids content werevaried from 4.18 ± 0.99 (tomato) to 14.11 ± 0.99 (mango) ° Brix. The highest pH value was obtained on the papaya (5.61 ± 0.08) while the lemon was the most acidic fruit with a pH of 2.47 ± 0.08. The oviposition preference results revealed that papaya and mango were the most preferred hosts by B. dorsalis among tested fruits in choice and no-choice tests. However lemon was the least preferred fruit in this study.Mango seems to be the most favorable fruit for the development of B. dorsalis with a shorter development time (18.68 ± 0.61 days) after the papaya (17.68 ± 0.61 days) and a higher percentage of eggs survival to puparia (67.83 ± 8.11%) as compared to other fruits. However lemon was the unfavorable fruit for offspring survival of B. dorsalis, with a longer development time (22.16 ± 0.61 days) and a lower percentage of eggs survival to puparia (19.09 ± 11%) as compared to other fruits.

The Variation of Oviposition Preference and Host Susceptibility of the Oriental Fruit Fly (Bactrocera dorsalis Hendel) (Diptera: Tephritidae) on Commercial Mango Varieties

“…The fruit damage of B. dorsalis is also influenced by the fruit variety and its physiological characteristics [5,8,13,14]. Boinahadji et al [15] recorded that the oviposition preference and offspring emergence of B. dorsalis are high in mangoes, with a shorter development time relative to seven other fruits tested in their study in Senegal.…”

Developing an Effective Push–Pull System for Managing Outbreaks of the Invasive Pest Bactrocera dorsalis (Diptera: Tephritidae) in Nephelium lappaceum Orchards

“…The oriental fruit fly (Bactrocera dorsalis) is a highly destructive pest that poses a significant threat to global fruit production [1][2][3][4]. Originating from tropical and subtropical regions of Asia, this pest has a broad adaptability to various host plants [5] and exhibits robust reproductive capacities [6,7].…”

CRISPR/Cas9 Ribo nucleoprotein complex‐mediated editing of the OBP13 gene affected the response of male Bactrocera dorsalis (Diptera: Tephritidae) to methyl eugenol

“…Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is one among the catastrophic Tephritids (Boinahadji et al., 2020) capable of achieving up to 100% yield loss if management measures are not adopted (Miano et al., 2022). As these flies are ambiguous endophagous feeders, dispersive, efficient fliers with highly suited ovipositional behaviour of females to lay eggs deeper into the fruit mesocarp confer the chemical control less efficient and lead to resistance to insecticides.…”
