“…The oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), is one of the most widespread and destructive agricultural insect pests in the world [ 1 ]. It has a wide range of hosts and infests more than 250 kinds of fruits and vegetables, including citrus fruits, mangos, guavas, and peaches [ 1 , 2 ].…”

The sensilla on the antennae and maxillary palps are the most important olfactory organs, via which the insect can perceive the semiochemicals to adjust their host seeking and oviposition behaviors. The oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), is a major agricultural quarantine pest infesting more than 250 different fruits and vegetables. However, the sensilla involved in olfaction have not been well documented even though a variety of control practices based on chemical communication have already been developed. In this study, the ultrastructure of the sensilla, especially the olfactory sensilla on the antennae and maxillary palps of both males and females, were investigated with field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). Three types of olfactory sensillum types including trichodea, basiconica, and coeloconica, and two non-olfactory sensilla including both chaetica and microtrichia, were observed. Each of these three types of olfactory sensilla on the antennae of B. dorsalis were further classified into two subtypes according to the morphology and number of receptor cells. For the first time, the pores on the sensilla trichodea and basiconica cuticular wall were observed in this species, suggesting they are involved in semiochemical perception. This study provides new information on B. dorsalis olfaction, which can be connected to other molecular, genetic, and behavioral research to construct an integral olfactory system model for this species.

“…More detailed knowledge on the invasive pest B. dorsalis will contribute to developing effective strategies for its control and quarantine issues [15,16]. Although various pest management techniques have been employed [17,18,19,20], controlling this fly has mainly relied on spraying insecticides, and insecticides resistance in B. dorsalis has been reported in many countries [16]. Therefore, a reasonable method or strategy is necessary to reduce resistance that results from the overuse or improper use of insecticides.…”

Intrapuparial development is a special pattern of metamorphosis in cyclorrhaphous flies, in which the pupa forms in an opaque, barrel-like puparium. This has been well studied in forensic insects for age estimations. In this study, the intrapuparial development of a quarantine agricultural pest, Bactrocera dorsalis (Hendel), was studied under a constant temperature of 27 ± 1 °C and 70 ± 5% relative humidity. Results showed that intrapuparial development could be divided into five stages: Larval-pupal apolysis, cryptocephalic pupa, phanerocephalic pupa, pharate adult, and emergent adult. It lays a morphology-based foundation for molecular mechanism studies and enhances the understanding of the physiological basis for changes in intrapuparial development. More importantly, the chronology of intrapuparial development can be used to predict the emergence time of tephritid flies, indicating when to spray insecticides to control these phytophagous agricultural pests. This may be an effective approach to reduce the use of insecticides and slow down the evolution of insecticidal resistance.

“…Various methods, including sterile techniques, and bait sprays have been used to control this pest . However, management efforts have relied mostly on chemical control, and thus, insecticide resistance is common in this fly; in fact, rapid development of insecticide resistance is a major obstacle to its control . Thus, examining the mechanisms of insecticide resistance in B. dorsalis , resulting from overexpression of metabolic enzymes, is needed urgently.…”

BACKGROUNDBactrocera dorsalis (Hendel) is a notorious agricultural pest worldwide, and its resistance to insecticides is a major obstacle in successful control. Cytochrome P450s (P450s) are major metabolic enzymes associated with insecticide resistance. The genome of B. dorsalis was sequenced recently, allowing an integrated genome‐wide analysis of P450 genes (P450s) and the analysis of correlations between these genes and insecticide resistance in this pest.RESULTSTotally, 101 P450s were identified in the B. dorsalis genome and classified into four clans, 25 families and 57 subfamilies. Quantitative reverse transcription polymerase chain reaction results showed that most of these genes were highly expressed in adults (46) and in metabolic tissues, including the fatbody (63), midgut (61) and Malphagian tubules (66). In a malathion‐resistant strain, 13 and 9 genes were significantly upregulated and downregulated, respectively, compared with a susceptible strain, and these genes were screened as candidate genes associated with malathion resistance.CONCLUSIONThis study provides useful information for understanding the evolution and potential functions of P450s in B. dorsalis, and the results lay the foundation for further studies on the correlations between P450s and malathion resistance in B. dorsalis. © 2020 Society of Chemical Industry
