Data from: Fitness and host use remain stable in biological control agent after many years of hybridization

    This data was generated to test how hybridization of an introduced insect biological control agent impacts host use. The data characterize the species composition of individual *Diorhabda spp.* collected across New Mexico and Texas, USA. Species composition of each individual was determined using genomic methods and Structure. Lab reared colonies were tested for host specificity, by measuring feeding preference in 24-hour feeding tests and measuring frass deposited below three host plants. Data on several attributes were also collected, including body mass, fecundity during the 24-hour feeding trial, and oviposition preference. The larval offspring of these individuals were also reared in families for 12 days on the three host plants and larval survival and mass were measured to quantify larval performance on the hosts.

      This dataset contains all data and code necessary to reproduce the analysis described under the heading "Experiment 3" in the manuscript: Taliercio, E., Eickholt, D., Read, Q. D., Carter, T., Waldeck, N., & Fallen, B. (2023). Parental choice and seed size impact the uprightness of progeny from interspecific Glycine hybridizations. Crop Science. https://doi.org/10.1002/csc2.21015 Included are .Rmd notebook containing code, HTML rendered output of notebook, and .xlsx data files required to reproduce analyses described in notebook.

      Data from: Long-lasting insecticide-incorporated netting and interception traps at pilot-scale warehouses and commercial facilities prevents infestation by stored product beetles

        Data are presented from a study of the efficacy for insecticide netting and interception traps in pilot-scale and commercial food facilities. Excel files cover: Attraction Assessment; Dose Dependency Data; Spillage Trap Collections; Spillage Trap Progeny; Trial 1 Recapture; Trial 1 Progeny Production; Trial 2 Recapture; Trial 2 Progeny Production.

        GENOSIM

          The genosim package simulates genotypes, breeding values, and phenotypes; simulates DNA sequence read depth (numbers of A and B alleles); and resolves SNP conflicts between parent and offspring genotypes.

          Non-dominated Sorting Genetic Algorithm-II

            This code is implements the nondominated sorting genetic algorithm (NSGA-II) in the R statistical programming language. The function is theoretically applicable to any number of objectives without modification. The function automatically detects the number of objectives from the population matrix used in the function call. NSGA-II has been applied in ARS research for automatic calibration of hydrolgic models (whittaker link) and economic optimization (whittaker link).

            Data from: Life history changes in Trogoderma variabile and T. inclusum due to mating delay with implications for mating disruption as a management tactic

              Egg and progeny counts for Trogoderma variabile and Trogoderma inclusum adults with delays in mating. These data were generated to examine the effect of mating delay on life history and reproductive capacity as a cue to the use of mating disruption tactics such as pheromone lures. Survivorship was calculated as the last day egg counts were recorded for an individual. Blocks were adults that were all mated on the same day. Reps are an individual female. Control beetles are coded with either an "f" or an "m" for female and male and were never mated. Male control data was examined for similarity to female control data but was not used in further analysis and comparison. The experiment was all done at 30C, 65% relative humidity and a 16 light/8 dark photoperiod. Adults were transferred every 2 days to new vials and eggs were then counted and save for progeny counts. Trogoderma variabile populations were laboratory colonies for over 20 years. T. inclusum populations were collected in Kansas in August of 2012. We did not transform these data.

              Data from: Defensive aphid symbiont Hamiltonella defensa effects on Aphelinus glycinis and Aphelinus atriplicis

                *Aphelinus glycinis* was collected in the Peoples Republic of China under a Memorandum of Understanding between their Ministry of Agriculture and the United States Department of Agriculture (USDA). *Aphelinus atriplicis* was collected by employees of the USDA, Agricultural Research Service (ARS), in the Republic of Georgia with the permission of that government. The parasitoids were imported into the USDA, ARS, Beneficial Insect Introductions Research Unit containment facility in Newark, Delaware, under permits from the USDA, Animal and Plant Health Inspection Service (Permit Numbers P526P-08-02142 and P526P-09-01929). No specific permissions were required to collect *Aphis craccivora* or *Acyrthosiphon pisum* because these are cosmopolitan aphids that occur in the field throughout North America. None of the species collected or studied are endangered or protected.
