Brown planthopper is the most important rice pest in Indonesia. Its high adaptability to feed and reproduce on previously introduced resistant varieties to form more virulent population often causes BPH outbreak and hopperburn that lead to total crop yield loss. Rice breeding for resistant to BPH requires information on the current status of BPH virulences in the fields to anticipate the virulence adaptation on new varieties. The objectives of this study were to investigate the degree of virulence of BPH populations and to cluster the BPH virulence to form BPH core collection. Thirteen BPH populations collected from paddy fields in six provinces (Banten, West Java, Central Java, East Java, South Kalimantan, and South Sulawesi) in 2011 and 2013 were tested on 10 differential rice varieties and seven host varieties of BPH populations, using the standard seedbox screening technique. Based on resistance reaction of four differential varieties (TN1, Mudgo, ASD7, and Rathu Heenathi), most BPH populations were identified as more virulent than biotype 4 (T1, Banten, PG, West Java; BY, East Java; B2 and B3, South Kalimantan; X1 and X3, South Sulawesi), four populations were biotype 4 (JWDL, Central Java; SD, East Java; X2 and X4, South Sulawesi), and one population each was biotype 3 (T2, Banten) and biotype 2 (S1, West Java). Populations X1 and B3 showed broad virulences to all varieties, whereas T2 was the least virulent. BPH field’s population had evolved into more virulence than biotype 4. Genotype resistance screening should use the BPH of this virulence population. Five BPH clusters which were further divided into 10 subclusters representing differential virulence toward 10 differential varieties were present in the tested BPH. Each virulence cluster was characterized by its ability to overcome four to eight single or double resistant genes. This BPH virulence core collection can be used in the characterization studies of candidate for resistant varieties or to form near-isogenic lines, or to study the insect and rice plant interaction.

16039 To have a better understanding of the current status of symptom management the national multi-center epidemiological study among patients with advanced cancer was initiated in Russia in 2005. Specific aims of this study are to describe the prevalence of pain, fatigue, and other cancer-related symptoms among cancer patients being treated in multiple sites across Russia and to assess current symptom treatment and response to it across different centers. The expected sample size is 500 patients with advanced cancer from 10 cancer centers across Russia. Symptom status was assessed using M.D. Anderson Symptom Inventory and Brief Pain Inventory at two time points. The analysis of data from 252 patients: male/female ratio - 111/141, mean age 44.3 (SD 30.1), included in the study from all participating centers is presented. As a result, the most severe symptom was fatigue (4.3) with its prevalence of 83.7%. Other pronounced symptoms were pain (3.4), distress (3.4), and sadness (3.1) with the prevalence of 66.7%, 67.7%, and 68.7% respectively. Out of the total sample, 70 patients (27.7%) had only mild symptoms and 179 patients (71%) reported at least one symptom as moderate-to-severe. Among them there were 72 patients (40.2%) who had 5 or more moderate-to-severe symptoms and 10 patients (5.6%) who had 10 or more such symptoms. Fatigue was treated only in 66 (26.9%) patients; the decrease in fatigue level was achieved in 15 (22.7%) patients. Inadequate pain management (as confirmed by the negative value of the Pain Management Index) was provided for 38.5% of patients. In conclusion, fatigue was prevalent in the vast majority of advanced cancer patients, but the attending oncologists offered the treatment of this symptom to less than 30% of patients. In addition, two thirds of patients reported at least one moderate-to-severe symptom. The results of this symptom outcome study will provide the initial data on symptom control in Russia and will establish the framework for identifying the populations who experience poor symptom assessment and management. No significant financial relationships to disclose.

Refining integrated rice tungro disease management based on escaped strategy and varieties rotation. Rice tungro virus transmitted mainly by green leafhopper, N. virescens, infected rice in central rice  production in Indonesia. Tungro epidemic in South Sulawesi were succesfully controlled by integrating appropriate planting time and rotation of green leafhopper resistant varieties since 1973. Tungro was reported in 1998 after climate anomaly, caused by El-Nino and La-Nina. Pattern of green leafhopper population fluctuation and tungro disease incidence and green leafhopper adaptation to green leafhopper resistance variety were evaluated. The results showed that the fluctuation pattern of green leafhopper population in Lanrang which represents of areas  in Eastern Coarse of South Sulawesi  has changed. Green leafhopper colonies from endemic area in South Sulawesi were almost all well adapted to 4 groups of green leafhopper resistance varieties. Therefore it was suggested to adjust planting date and recommended to plant tungro virus resistance variety instead of green leafhopper resistance varieties.

An examination of some specialized lunar and planetary ephemerides has revealed inconsistencies in the adopted planetary masses, the presence of non-gravitational terms, and some outright numerical errors. They should be considered of temporary usefulness only, subject to subsequent amendment as required for the interpretation of observational data.
