Summary: DMP exhibits greater attractiveness to sexually mature males of the Oriental fruit fly than E-CF in laboratory bioassays, with varying responsiveness throughout the day. Toxicological experiments demonstrate that DMP is non-toxic, showing promise as an effective lure for controlling B. dorsalis.

Summary: In this study, the CncC gene of Bactrocera dorsalis was cloned and its protein structure was analyzed. The expression levels of the gene in different developmental stages and tissue sites were investigated. The study provides a theoretical basis for further understanding the function of CncC in regulating pesticide resistance in B. dorsalis.

Summary: This study utilized SMRT sequencing to analyze the full-length transcriptome of Bactrocera dorsalis, identifying a large number of SSR genetic markers that could be used for population research. The results lay a foundation for further understanding the genetic diversity and population structure of B. dorsalis.

Summary: The massive use of synthetic pesticides leads to environmental pollution and health hazards. Plant secondary metabolites dominated by terpenoids have the potential to be developed as novel alternatives to synthetic chemicals. In this study, the toxicity, oviposition deterrence, and repellent activities of six major essential oil constituents were evaluated against the oriental fruit fly. The results suggest that these essential oil constituents have the potential to be used as alternative pesticides against B. dorsalis.

Summary: This study used different greenhouse gas emission scenarios and the MaxEnt model to predict the potential distribution of Beauveria bassiana and Bactrocera dorsalis. The results show that the distribution area of B. bassiana will increase under the RCP8.5 scenario, but decrease under the RCP2.6 scenario.

Summary: The Oriental fruit fly is a highly destructive and invasive pest of fruits. The male annihilation technique (MAT) and the sterile insect technique (SIT) have been used for its control. However, the efficacy of both techniques is reduced due to the inability to attract non-ME-responsive males.

Summary: Male lure dispensers and traps have different effects on monitoring fruit fly pests, with higher ME loadings being more effective for B. dorsalis and yellow Delta traps baited with TML being effective for C. capitata monitoring. The type of dispenser and trap used should be considered for efficient monitoring of target pests.

Summary: The infestation of agricultural commodities by insect pests, such as the highly invasive Oriental fruit fly (Bactrocera dorsalis), poses economic, import and export, food safety, and invasive insect introduction issues. Detecting infestations early on is crucial for ensuring food safety and controlling the spread of invasive insects. This study investigated the odors of infested mangoes to identify compounds that can be used for rapid and non-destructive detection of infested fruit.

Summary: The oriental fruit fly, Bactrocera dorsalis, is a damaging insect pest that has developed resistance to various chemical insecticides. This study identified several glutathione S-transferases (GSTs) in B. dorsalis and characterized their relationships with five insecticides. It was found that an antenna-abundant BdGSTd8 responded to four different classes of insecticides. Further analysis confirmed that BdGSTd8 is primarily located in the antenna and has the ability to enhance cell viability by interacting with specific insecticides. These findings enhance our understanding of GST characteristics in B. dorsalis and their role in detoxification.

Summary: Insect responses to chemical attractants are often measured using olfactory bioassays. This study compares the effectiveness of three common bioassay methods (Y-tube, small-cage arena, and rotating carousel field-cage) for measuring the attraction of Bactrocera dorsalis to methyl eugenol (ME). The results show that the rotating carousel field-cage and small-cage arena methods are effective at observing attraction to ME and detecting a significant reduction in ME response from ME-exposed males, while the Y-tube method is not suitable for this purpose.

Summary: This study evaluated the effects of different soil depths on the survival, normality, and development time of interspecific hybrids of Bactrocera carambolae and B. dorsalis. The results showed that soil depth had a significant, negative impact on emergence survival and development time. The best emergence rate and survival were observed at 4 cm and 10 cm depths, while the lowest survival occurred at depths of 50 cm and 60 cm.

Summary: Currently, insect populations are mainly controlled by killing males through sexual attractants. However, the mating ability of attracted insects may limit the effectiveness of sex attractants. A study on the Oriental fruit fly, Bactrocera dorsalis, revealed that males can mate an average of 11 times, while females only mate 1.93 times, with 10.81% of males mating more than 20 times. The reproductive capacity of male B. dorsalis significantly decreased after four to five instances of continuous mating. Different mating patterns showed that interval mating was the most effective and not polyandry. This behavioral evidence revealed a limiting factor to the effectiveness of sex attractants in B. dorsalis.
