“…Similar levels of damage were also reported respectively in Bhutan and China by (Dorji et al, 2006;Xia et al, 2018). In western Bengal, its infestation was about 50.83% (Pashi et al, 2021). The lower mandarin losses to the CFF in Gandaki Province was mainly due to the management interventions adopted by the Agriculture Knowledge Centers and Prime Minister Agricultural Mechanization Project after an alert issued by the DoAR, Lumle (DoAR, Lumle, 2021).…”

“…Probably, this was a reason why the farmers were facing pest burden even after they were following the management practices. This was supported by a research of where they reported only 10.40 and 15.27% infestation in managed citrus orchard as compared to 40.09% infestation in unmanaged orchards of West Bengal (Pashi et al, 2021). On and above these, the citrus growers had tendency to wait for many days to collect large numbers of fallen fruits until when the larvae inside the fruits might have migrated into soil for pupation.…”

To ascertain the mandarin yield damage and pupal-density based future damage potential due to recent invasion of Chinese fruit fly (CFF) Bactrocera minax (Enderlein), a semi-structured questioning with commercial citrus growers of Gandaki Province and a field level assessment of the pupal density were carried out. Results revealed that the mandarin growers were facing sever CFF-infestation since 3-4 years, the fruits drop starting in July-August and reaching peak in September of the season leading into an average yield loss of 16.63±1.68% in Gandaki Province. Though 64% of the respondents were adopting collection and disposing of the fallen infested mandarin fruits leading into a significant decrease (78.95 ± 5.69% and 72.48 ± 3.17%, respectively in 2021 and 2022) in CFF pupal population, there were plenty of larvae gone for pupation which could be sufficient to infest the next-season mandarin. Therefore, an area-wide control measure focusing on orchard sanitation is imperative.

This study conducted between January and June 2022 aimed to assess the impact of precipitation on Bactrocera minax, a citrus pest, in Nepal's Solukhumbu and Sindhuli districts. Primary data were gathered from 84 respondents using pre-tested interview schedules, focal group discussions (FGD), and key informant interviews (KII), while secondary information was collected through literature review. The results highlighted the Chinese citrus fruit fly as a significant citrus pest causing fruit drop, particularly impacting Mandarin cultivation after sweet orange displacement. Farmers in Sindhuli exhibited greater motivation and trust in citrus cultivation compared to those in Solukhumbu. Notably, the fruit drop was lower (4.33%) in Sindhuli where the Area-wide Management Program (AWCP) utilizing protein bait and field sanitation was applied, in contrast to Solukhumbu where fruit drop was higher (35.5%), suggesting the effectiveness of AWCP. The PMAMP Sindhuli super zone played a direct role in the study, with respondents in Sindhuli demonstrating higher awareness of Chinese citrus fruit flies and AWCP. Technical and financial support for citrus cultivation was also more prevalent in Sindhuli. Furthermore, the study found that the majority of respondents perceived protein bait (AWCP) as the most straightforward, effective, and expensive management method, despite its limited application in Solukhumbu. This study underscores the importance of AWCP in mitigating citrus pest infestation, particularly in areas with high precipitation, and emphasizes the need for broader adoption of effective management strategies in citrus cultivation regions.

“…The highest number of fruit flies in Sadi might be due to suitable environmental conditions and host availability for fruit flies. Pashi et al (2021) found the infestation rate was affected by altitudes. These findings found to be in line with the results of Leblanc et al (2019), where B. dorsalis, Z. cucurbitae, B. nigrofacia, B. zonata and Z. tau is abundant at places of lower and mid altitudes than higher altitudes.…”

Fruit flies (Diptera: Tephritidae) are devastating pests in citrus orchards of Nepal causing huge losses of fruits. A farmer's survey was carried from March to December, 2021 randomly selecting 40 citrus orchard owners, and at the same time, a field monitoring of fruit flies organised in randomized complete block design with 7 times replicated 3 treatments (Cue lure and malathion in Steiner trap, Methyl eugenol and malathion in Steiner trap and protein bait in McPhail trap) were conducted in Ramechhap district of Nepal. Survey revealed that Chinese citrus fly was the most problematic insect pest of citrus orchard. However, only few farmers were practising effective control measures against this pest. Nine species of fruit flies were trapped in different lures and protein bait, when the number of fruit flies differed significantly (p<0.05) except Bactrocera correcta and Zeugodacus cucurbitae, which were found attracted in negligible number in Methyl eugenol and Cue lure, respectively. Z. scutellaris, Z. tau, B. nigrofemoralis were attracted to Cue lure. B. dorsalis and B. zonata were attracted to Methyl eugenol and B. minax, B. nigrofemoralis and Dacus sphaeroidalis were attracted in protein bait. The study concluded that the male lures and protein bait were useful to monitor specific fruit fly species in citrus orchards, hence their management strategies should be made accordingly.
