Soybean Aphids per Plant Among Soybean Lines Containing Various Rag Genes

    The files presented here report the number of soybean aphids on soybean lines that differed in the *Rag* genes they contained. Tests were conducted separately against two soybean aphid colonies, which were maintained on soybean plants at North Central Agricultural Research Laboratory (NCARL), USDA-ARS, Brookings, South Dakota, USA.

    Data from: Comparative analysis of genome sequences from four strains of the Buchnera aphidicola Mp endosymbiont of the green peach aphid, Myzus persicae

      Myzus persicae, the green peach aphid, is a polyphagous herbivore that feeds on hundreds of species of mostly dicot crop plants. Like other phloem-feeding aphids, M. persicae rely on the endosymbiotic bacterium, Buchnera aphidicola (Buchnera Mp), for biosynthesis of essential amino acids and other nutrients that are not sufficiently abundant in their phloem sap diet. To determine whether the endosymbiotic bacteria of M. persicae could play a role in tobacco adaptation, the Buchnera Mp genomes from two tobacco-adapted and two non-tobacco M. persicae lineages are sequenced.

      Data from: Phylogeography of the Wheat Stem Sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae): Implications for Pest Management

        The wheat stem sawfly is a key pest of wheat in the northern Great Plains of North America, and damage resulting from this species has recently expanded southward. The genetic divergence between samples collected in North America and northeastern Asia using two mitochondrial regions (COI and 16S) are examined. The structure of genetic diversity in the main wheat producing areas in North America are also characterized using a combination of mtDNA marker and microsatellites in samples collected both in wheat fields and in grasses in wildlands.

        Data from: A High-Quality Genome Assembly from a Single, Field-collected Spotted Lanternfly (Lycorma delicatula) using the PacBio Sequel II System

          A 2.3 Gb *de novo* genome assembly of a field-collected adult female Spotted Lanternfly (*Lycorma delicatula*) using a single PacBio SMRT Cell is provided. Supporting files for the manuscript "A High-Quality Genome Assembly from a Single, Field-collected Spotted Lanternfly (*Lycorma delicatula*) using the PacBio Sequel II System", include several intermediate versions of the assembly (raw output from Falcon, raw output from Falcon unzip, etc.) as well as the final assembly primary contigs and haplotigs (for the regions of the genome that were phased).

          SGA Pro (elevator storage)

            Stored Grain Advisor (SGA) is a decision support system for managing insect pests of farm-stored wheat. The program predicts the likelihood of insect infestation, and recommends appropriate preventative actions . It also provides advice on how to sample and identify insect pests of stored wheat. SGA Pro was designed for use in commercial elevators as part of the Areawide IPM Project for stored grain. Grain samples are taken with a vacuum probe and processed over an inclined sieve. SGA Pro analyzes the insect data, grain temperatures and moistures, and determines which bins need to be fumigated.

            AgroAtlas

              The Russian-English Agricultural Atlas is the world’s most comprehensive source of information on the geographic distribution of plant-based agriculture in Russia and neighboring countries. The Atlas contains 1500 maps that illustrate the distribution of 100 crops, 560 wild crop relatives, 640 diseases, pests and weeds, and 200 environmental parameters. Additionally, the Atlas provides detailed biological descriptions, illustrations, metadata and reference lists. Currently, individual maps can be downloaded and viewed using freely available AgroAtlas GIS Utility software, which can also be downloaded at this site.
