This study examined whether low-density co-inoculation of Myanmar Bradyrhizobium yuanmingense strain MAS34 and Streptomyces griseoflavus P4 would enhance nodulation, N2 fixation, and seed yield in two soybean varieties. A field experiment was conducted during the July to November 2012 growing season at Kyushu University Farm, Japan, using a split-plot design with three replications and the following four treatments: T1, an uninoculated treatment with peat moss (uninoculated);T2, a single inoculation with S. griseoflavus P4 (P4);T3, a single inoculation of B. yuanmingense MAS34 (MAS34);and T4, a dual inoculation of P4 with MAS34 (P4 + MAS34). Two varieties of soybean, Yezin-3 (Rj4) and Yezin-6 (non-Rj), were used. The N2 fixation activity of soybean was evaluated by the relative ureide method using xylem solute from root bled sap at the early pod-fill stage (R3.5). Dry matter production, N2 fixation, and seed yield were significantly (P 0.01) different between the inoculated treatments. The effect of variety was also significant (P 0.05) for nodule dry weight at the V6 stage, percentage of N derived from the atmosphere at the R3.5 stage, and seed yield at the maturity stage. The number of nodules on the tap roots was significantly higher in Yezin-3 than in Yezin-6. The single inoculation of P4 did not have a significant effect on dry matter production, N2 fixation, and seed yield in either soybean variety. The dry matter production, relative ureide index, percentage of N derived from the atmosphere, and seed yield were significantly (P 0.01) enhanced by a single inoculation of MAS34 in Yezin-3 and by dual inoculation of P4 + MAS34 in Yezin-6. These results indicate that low inoculum concentrations (105 cells seed-1) increase N2 fixation and seed yield in these soybean varieties under open field conditions. Myanmar B. yuanmingense MAS34 and S. griseoflavus P4 are expected to be useful biofertilizers for soybean production.

Black gram (Vigna mungo L. Hepper) is one of the main leguminous crops that provide chief source of food. Several Bradyrhizobium species are able to induce effective nodules in black gram cultivars. In the present study, we characterized forty isolates of indigenous black gram bradyrhizobia from Myanmar based on the sequence analysis of the bacterial 16S rRNA gene. The sequence analysis confirmed that all isolates were categorized and identified as the genus Bradyrhizobium and they were conspecific with B. elkanii, B. sp., B. liaoningense, B. japonicum and B. yunamingense. Almost all the collected isolates from major black gram growing regions of Nyaunglebin Bago Regio, Chaungzon Mon State, Sittwe Rakhine State, Danubyu Ayeyarwady Region and Launglon Tanintharyi Region were identified as B. liaoningense. At Danubyu Ayeyarwady Region and Pyinmanar Nay Pyi Taw Region, most of the strains were identified as B. japonicum. On the other hand, more or less all the isolates from Launglon Tanintharyi Region and Hpa-an Kayin State were related to B. elkanii. However, all B. sp. strains were found in Salingyi Sagaing Region black gram growing region. This is the first report describing Bradyrhizobium strains that were isolated from soil samples of major black gram growing areas in Myanmar. Evaluation of the effectiveness of Myanmar Bradyrhizobim strains isolated from soil samples of major black gram growing areas of Myanmar for plant growth and nitrogen fixation was studied in pot experiments with completely randomized design and three replicates. The nodule dry weight, shoot dry weight and acetylene reduction activity of the plant inoculated with Bradyrhizobium elkanii LauBG38 were significantly higher in ARA per plant, nodule and shoot dry weights than the other tested isolates in both Yezin-4 and Yezin-7 black gram varieties. We expect that Myanmar Bradyrhizobium elkanii LauBG38 will be able to use as Biofertilizer for black gram cultivars.

Paddy fields are natural and artificial wetland ecosystems that supply rice for the people and provide the wildlife especially insect diversity of different functional aspects. A total of 71 insect species belonging to 40 families under eight orders were observed during the study period. Among the 71 insect species, 18 species of beetles, nine species of bugs, eight species of dragonfly, five species of butterflies, four species of leafhoppers, plant hoppers and moths, three borer and spiders, two crickets, one species of skippers, grass hopper, hispa, ant, weevil, hairy caterpillar, leaf roller, katydid, thrips, maggot and water boatmen were recorded in the study sites. Total of 41 species of pests, 18 species of predators and 12 species of beneficial species (they function as pollinating the flowering plants in the paddy field wetland ecosystem) were recorded in the study sites. In the monsoon season, the 41 species of pest species, 18 species of predator species and 12 species of beneficial species were recorded from monsoon rice field. According to Shannon Evenness value (H'/S = -0.012564), the data showed that the insect species recorded from the one habitat was not the similar to another. In summer paddy fields, 36 species of pest species, 16 species of predator species and 9 species of beneficial species were recorded. Total arthropod insect species were recorded 61 species from the dry rice fields. According to Shannon Evenness value (H'/S = -0.000120), the data showed that the insect species recorded from the one habitat was not the similar to another. Population growth and duration of life cycle of insects is mainly dominated by the temperature, the duration of life cycle is shorter in the high temperature than in the low temperature.

Prevalence rate of Aedes aegypti was conducted in 20 houses from semi-urban areas of Yangon Region. Larval surveys were done at indoors and outdoors water containers of five types. Prevalence rate of larval density larvae was investigated monthly by standard indices. The highest infestation rate of the container index (CI) was in June 2018 (56.52%), the second highest was in July 2017 (48.36%) and the lowest rate was in April 2017 (5.07%);those of the Jar index (JI) was highest (36.49%) in June and second highest rate (23.8%) was in October 2017. Reasoning the Metal drum (MI) was highest (13.95%) in June 2018 and second highest (6.25%) was in July 2017. The larval infestation rate of Earthen pot (EI) was highest (42.1%) in July 2017. The larval incident rate in almost all indices showed that the highest rate was at the beginning of monsoon season, in June and July, while in the remaining months, the larval incident rate was found to decrease due to the application of insecticides in the study area by the Township Public Health Department. However, the application of insecticides did not cover all the breeding sites of the mosquitoes, the water puddles under their houses were left to apply the insecticides. The positive larval incident rate was assessed by Household (HI), Container index (CI), Breteau index (BI). The highest and second highest positive larval incident rates were all in June 2018 and July 2017 in all indices, HI (27.3% and 23.4%), CI (56.52% and 48.36%), BI (17.56% and 16.79%) and SI (28.49% and 24.38%) respectively. The lowest rate in all indices was 2.56% (HI), 5.07% (IC), 2.67% (BI) and 1.91% (SI) in April. In this study, the fluctuation of indices of infestation rates and positive larval index value was positively correlated in similar trends in the study months. The reason for difficult control measure depends on the water sources under their houses and remains stagnant throughout the year, even in the dry season. High incident and death r

The active Sagaing fault in Myanmar defines the boundary between the Indian Plate and the Eurasian Plate and causes seismic damage in the major cities of Myanmar. Small bodies of serpentinite occur along the fault. We for the first time investigated the highly sheared serpentinite bodies in the Sheinmagar area and Yega Inn area along the Sagaing fault. Extensively sheared/brecciated serpentinites and related rocks, such as talc and/or chlorite-bearing rocks contains small rock fragments of serpentinites. Serpentine texture and mineral chemistry indicate that the protolith of these serpentinites were mainly harzburgite with minor amounts of dunite, some of which are cut by gabbroic veins. No shape-preferred orientation of the antigorite is present, indicating that the serpentinization was occurred under relatively static conditions. Protolith and serpentine minerals are similar to those of the jadeitite-bearing serpentinites in the north of the Sagaing fault(the Jade Mine belt). Chemical variations of spinels in the studied area are within the compositional range of forearc peridotites and those in the mantle section of nearby ophiolites. After the formation of antigorite serpentinite under static conditions, these serpentinites were subsequently, but locally deformed, probably due to the activity of the Sagaing fault, resulting in the formation of serpentinite schist/brecciated rock. The presence of the less-deformed antigorite serpentinite in the sheared/brecciated zone indicates the strain localization mainly along the surrounding serpentine-talc(±chlorite) schistose rocks, which is probably formed by the reaction between serpentinite and country rocks. Further studies are needed to better understand whether the distribution of serpentinized peridotites cause variations in the activity of the Sagaing fault.

A total of 288 patients infected with HCV genotypes 1, 2, 3 and 6 were treated with peg-IFN alpha-2a(180 μg/wk) or alpha-2b(50 to 100 μg as a weight-based dose) and RBV as a weight-based dose(15 mg/kg/d). Treatment duration was 48 wk for genotypes 1 and 6, 24 wk for genotype 2, and 24 or 48 wk for genotype 3 based on rapid virologic response(RVR). Those co-infected with hepatitis B received 48 wk of *** Overall, SVR was achieved for 82% of patients and the therapy was well tolerated. All patients achieved SVR at equivalent rates regardless of HCV genotype(P = 0.314). Low fibrosis scores(P 96% positive predictive value for achieving SVR. Treatment duration did not significantly impact the likelihood of achieving SVR for patients infected with genotype 3 HCV(P = 0.371). The most common adverse events were fatigue(71%) and poor appetite(60%). Among patients with genotype 3 HCV, more patients in the 48-wk treatment group required erythropoietin than in the 24-wk treatment group(61.1% vs 49.2%).CONCLUSION SVR rates were high with peg-IFN and RBV therapy in Myanmar. Fibrosis scores, baseline albumin, HCV RNA levels and RVR independently predicted SVR.

Advances in Entomology 2021年第1期9卷 49-58页

作者： Kyaw Lin Maung Yin Yin Mon myat Phyu khine khin Nyein Chan Aye Phyoe Aye Thandar soe Thae Yu Yu Han Wah Wah Myo Sein Su Su San Aye Aye Khai Biotechnology Research Department Department of Research and Innovation Ministry of Education (Science and Technology) Kyaukse Myanmar

Mango is one of the largest commercial fruits in Myanmar and the fruit fly, B. dorsalis and B. correcta are the major pests. Mango is a kind of native fruit which can grow well as natural vegetation throughout the entire country under the various climatic conditions. We aimed to point out overuse of insecticide application in agricultural sector of Myanmar and further criteria of effective fruit fly control techniques were also proposed for worldwide ecosystem. Traditional fruit fly control is primarily focused on the uncoordinated use of insecticide applications which is orchard-by-orchard strategy. However, in view of flying distance, this localized strategy is not successful and harms the ecosystem. Occasionally, fruit bagging technique was applied by some farmers. In Myanmar’s agricultural sector, numerous varieties of cheap insecticides which mostly imported from China were plentiful. While conventional insecticide application controls were implemented annually, the population of fruit flies increased year after year, particularly in tropical region. The requirement of technical-scientific research reduced the worldwide fruit fly records. Furthermore, traditional insecticide application approach inhibits the yield and quality of mangoes that have adversely affected international trade. Importantly, in long term period of the entire previous decade, the conventional insecticide application controls make more fruit fly infestation.
