ABSTRACT The brown planthopper (Nilaparvata lugens Stål), the most destructive pest of rice, has been identified, including biotypes with high virulence towards previously resistant rice varieties. There have also been many reports of a yeast-like symbiont of N. lugens, but little is known about the bacterial microbes. In this study, we examined the bacterial microbes in N. lugens and identified a total of 18 operational taxonomic units (OTUs) representing four phyla (Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes) by sequencing and analyzing 16S rRNA gene libraries obtained from three populations of N. lugens, which were maintained on the rice varieties TN1, Mudgo, and ASD7. Several of the OTUs were similar to previously reported secondary symbionts of other insects, including an endosymbiont of the psyllid Glycapsis brimblecombei, an Asaia sp. found in the mosquito Anopheles stephensi, and Wolbachia, found in the mite Metaseiulus occidentalis. However, the species and numbers of the detected OTUs differed substantially among the N. lugens populations. Further, in situ hybridization analysis using digoxigenin-labeled probes indicated that OTU 1 was located in hypogastrium tissues near the ovipositor and ovary in biotype 1 insects, while OTU 2 was located in the front of the ovipositor sheath in biotype 2 insects. In addition, masses of bacterium-like organisms were observed in the tubes of salivary sheaths in rice plant tissues that the insects had fed upon. The results provide indications of the diversity of the bacterial microbes harbored by the brown planthopper and of possible associations between specific bacterial microbes and biotypes of N. lugens.

The Impact

Aim: To evaluate the impact of saline irrigation water on yield, quality and economics of various rice varieties under different agronomic management options. Study Design: The experiment was laid out in strip-plot design with three replications. Place and Duration of Study: At College Farm, College of Agriculture, Rajendranagar, Hyderabad, during kharif, 2018. Methodology: After the preliminary layout, local variety of dhaincha was broadcasted in the experimental site with seed rate of 40 kg ha-1 and incorporated during initiation of flowering in the respective treatment plots. Farm Yard Manure (FYM) (10 t ha-1) was applied and thoroughly mixed with the soil. Four rice varieties RNR-15048, KNM-118, JGL11118 and CSR-36 were were choosen because of its popularity in Telangana and raised well in advance and transplanted in respective treatments. Results: The highest grain and straw yield was recorded by CSR 36 followed by (fb) RNR 15048 in combination with GM (In situ green manuring), Among the varieties, the highest amylose content was registered by JGL 11118 (24.16%) followed by RNR 15048 (21.9%). The highest L/B ratio was recorded by RNR 15048 (3.33) which was significantly higher than CSR 36 (3.20) and JGL 11118 (3.13). The highest head rice recovery was observed in CSR 36 which was on par with RNR 15048. In situ green manuring in RNR 15048 variety of Telangana received higher income. Under control treatment only the recommended dose of fertilizers (120:60:40 kg ha-1) was applied. Conclusion: GM should therefore be done under saline water irrigation in registering superior yield, quality and economics in RNR 15048 in the district of Telangana.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
