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.

    Data from: Mortality Dynamics of a Polyphagous Invasive Herbivore Reveal Clues in Its Agroecosystem Success

      Field-based, partial life table data for immature stages of silverleaf whitefly on 6 host plants including alfalfa, broccoli, spring and fall cantaloupe, cotton, ornamental lantana, and several species of annual weeds in Maricopa, Marana and Yuma Arizona, USA. Data provide the marginal, cause-specific mortality for eggs, and 1st, 2nd, 3rd, and 4th instar nymphs collectively and stage-specific marginal mortality for each stage over all causes.

      Systemic production of grapevine phenolics in response to mixed infections by wood-colonizing fungi

        This data is collected from two experiments, one in 2018 and one in 2019, that left untreated or inoculated grapevines with Diplodia seriata, Neofusicoccum parvum, Phaeomoniella chlamydospora, or mock-inoculated, and then two months later inoculated with one of the three pathogens. Grapevine stem phenolic levels were measured at the time of the second inoculation on a different branch, and comparisons were made between pathogen infected plants or those left non-inoculated. Lesion sizes of the second inoculations also were compared to examine the effects on the first inoculation on these.

        Data from: Host plant water deficit stress impairs reproduction and development of the galling fly (Parafreutreta regalis), a biological control agent of Cape-ivy (Delairea odorata)

          Data from choice and no-choice tests associated with the paper cited below. Drought leading to water deficit stress is known to reduce performance of galling insects. The shoot tip-galling fly Parafreutreta regalis has been released for biological control of Cape-ivy (Delairea odorata) in California. Lack of moisture during the dry season causes wilting of Cape-ivy shoots, and subsequent reduced host quantity and quality could influence the fly’s ability to multiply and establish. We imposed water deficit stress on potted Cape-ivy plants, then measured the plant’s and insect’s response to water deficit compared to fully-watered plants.
