Bactrocera dorsalis (Hendel, 1912) (Diptera: Tephritidae), commonly known as the oriental fruit fly, is a highly destructive pest that globally infests fruits and vegetables, resulting in significant annual economic losses. Initially detected Taiwan Island, it has rapidly expanded its distribution range to various regions mainland China since 1980s, with continuous northward spread. To mitigate damage caused by this pest, extensive efforts have been undertaken comprehend ecological physiological adaptations develop management strategies. This review article provides an overview of invasion history B. China, mechanisms facilitating invasion, progress made understanding major biological characteristics. Moreover, key approaches for managing or are likely be implemented presented, including quarantine measures, monitoring procedures, physical controls, sterile insect technique, RNA interference, CRISPR-Cas-9. Finally, some suggestions future research directions provided.

Bactrocera dorsalis is a major pest causing economic losses in fruit and vegetable production. Current control methods, such as synthetic pesticides male annihilation techniques, have drawbacks, including health risks, resistance development, ineffectiveness against females. This study investigates the attractions oviposition stimulant activities of five common volatiles-[isobutyl acetate (A), isoamyl (B), isobutyl butyrate (C), isovalerate (D), (E)]-from most preferred hosts: mango, guava, orange, banana. These volatiles were tested at three different concentrations, both individually complex blends. Choice tests performed using Y-tube olfactometer Petri plate with agarose assays, antennal responses determined electroantennogram (EAG) recordings. Among them, blend comprising 1.25% acerate (10.95 µg/µl), (10.75 20% (172.40 µg/µl) (B1D1E3) emerged potent attractant for sexes Moreover, combining B1D1E3 banana, or orange juice significantly enhanced egg-laying behavior. Electrophysiological recordings supported these findings, eliciting strongest responses. Results suggest could be used to elicit strong mass rearing B. Sterile Insect Technique.

Exotic tephritid incursions are of high concern to Australia’s biosecurity and its horticultural industries. It is vital that Australia remains ready respond as they arise, an incursion fruit fly species will result in significant economic losses. In this review, we compared Australian management strategies for flies with global identified possible areas where improvements could be made context. Overall, has a good understanding the main threats, which Bactrocera from across Torres Strait (northern Australia) most concern. Effective tools detection early warning surveillance at points entry place ports Australia-wide provide basis initiating responses event incursion. Area-wide control measures used successful eradication attempts globally available use Australia. However, specific emergency response plan identifying suitable options not yet available. We have policies exotic incursion, but speed accomplished would greatly improved by development species-specific plans.

The ability to recognize a host plant is crucial for insects meet their nutritional needs and locate suitable sites laying eggs. Bactrocera dorsalis highly destructive pest in fruit crops. Benzothiazole has been found induce oviposition behavior the gravid B. dorsalis. However, ecological roles olfactory receptor responsible benzothiazole are not yet fully understood. In this study, we that adults were attracted benzothiazole, which was an effective stimulant. vitro experiments showed BdorOR49b narrowly tuned benzothiazole. electroantennogram results knocking out significantly reduced antennal electrophysiological response Compared with wild-type flies, attractiveness of knockout adult attenuated, mutant females exhibited severe decrease behavior. Altogether, our work provides valuable insights into chemical communications potential strategies control pest.

Fruit volatiles play a crucial role in the host localization by oriental fruit fly, Bactrocera dorsalis Hendel (Diptera: Tephritidae). This study focused on identifying from Sanyue plum and Sanhua (Prunus salicina Lindl.), which are 2 varieties of same species, examined their impact behavior B. using Y-olfactometer. A total 35 54 were identified, respectively. Among these, 23 elicited electroantennographic (EAG) responses adults, showing concentration-dependent effects males females. Ethyl butyrate, butyl acetate, hexanoate, ethyl caproate, hexyl acetate significantly attracted compared to liquid paraffin, while nonaldehyde was avoided. There no significant difference behavioral both sexes sorbitol esters, isobutyrate, 1-tetradecene with control paraffin group. Interestingly, (3Z)-C-3-hexenyl females, but not males. The above findings suggest that likely facilitate adults may even aid mate-finding. opens up new avenues for exploring novel plant-based attractants might be value integrated management dorsalis.
