The Tephritidae family, commonly referred to as true fruit flies, comprises of a substantial group within order Diptera. Numerous species this family are major agricultural pests, with tendency infest wide array fruits and vegetables in tropical sub- regions, leading considerable damage consequent reductions the market value crops. current study was aimed propose promising solution menace posed by flies offering rapid, accurate reliable identification using character-based DNA barcode methodology. Tephritid specimens were collected from Cucurbitaceous plants southern parts West Bengal, India, total eight obtained belonging three genera, namely Bactrocera (Macquart, 1835), Dacus (Fabricius, 1805) Zeugodacus (Hendel, 1927). Their morphological features meticulously studied based on available literature, along genetic analysis mitochondrial COI ND1 gene sequences.

Abstract East Nusa Tenggara (ENT), an archipelagic region characterized by predominantly dry land, supports a wide range of horticultural crops, including mango, jackfruit, and watery rose apple, which are significant economic value for local regional markets. However, these crops face substantial threats from fruit flies (Diptera: Tephritidae), designated as Quarantined Plant Pest Organisms (QPPO) due to their highly destructive nature. If unmanaged, can lead severe yield losses ranging 30–75%, directly impacting crop quality farmer livelihoods. This study aimed identify characterize the diversity fly species infesting apple plants in Kupang City, ENT. Through field trapping morphological analysis, three primary were identified: Bactrocera dorsalis , carambolae musae . Each exhibited unique features across thorax, wing patterns, abdomen, facilitating accurate identification. Infestation was marked appearance black spots on skin, progressing water-soaked, rotting areas that ultimately caused premature drop. These findings highlight urgent need targeted management strategies mitigate impact infestations safeguard productivity key Tenggara.

Abstract Incursions by exotic tephritids continue to threaten Australia. Host suitability for a specific tephritid is ranked the number of adults which can emerge from one kg fruit or Reproduction Number (HRN). Bactrocera dorsalis has previously invaded northern Australia but was eradicated. However, remains largest threat and likely invade through B. tryoni other are already well established. One question what hosts would provide best early warning an incursion. Here, HRN 40 were established scientific literature. The reproductive advantages species over calculated dividing higher lower HRN. fruits with highest advantage (> 30) favouring soursop, mango capsicum. estimate compared surveillance data collected during eradication in north Queensland 1995 1997.

An automated monitoring system designed for was employed in this study elucidate annual population dynamics four counties: Yuanjiang, Huaping, Guangnan, and Ludian Yunnan. The utilizes sex parapheromone image recognition technology. data uploaded by device are used analyze different regions. results showed populations adult all counties peaked twice annually, with Yuanjiang experiencing earliest peak periods, followed Ludian. Adult occurred throughout year, had highest number monitored.
