Molecular Markers for Ornamental Cultivars of Weigela Weigela (Caprifoliaceae) is a popular ornamental genus that includes approximately 10 species, all of which are native to East Asia. Two species have mainly been hybridized to produce the currently available cultivars, but four other species have also been used to a lesser extent. Despite limited ge... Development and characterization of 20 genomic SSR markers for ornamental cultivars of weigela Weigela (Caprifoliaceae) is a popular ornamental genus, which includes species that have been hybridized to produce commercially available cultivars. Limited genetic resources currently exist for the genus. Whole-genome sequencing of Weigela Spilled Wine® was completed and 20 genomic simple sequence... Integration of physical and chemical tactics for managing Systena frontalis at ornamental nurseries The Red-headed Flea Beetle [Systena frontalis (F.); RHFB] is native to the central and eastern U.S. and has become a costly multivoltine pest of containerized nursery plants. We tested discs of long-lasting insecticidal netting (LLIN) secured over rims of plant containers in spring of 2023, using fo... Seasonal abundance and diversity of potential Xylella (Xanthomonadales: xanthomonadaceae) vectoring leafhoppers in Mississippi muscadine vineyards Pierce’s disease remains an important economic problem for producers of wine grapes, and while muscadine grapes do exhibit resistance, stressed or weakened vines can be more susceptible. Vector management may be a useful tool in limiting the pathogen spread within a vineyard, but knowledge of leafho... Integration of Physical and Chemical Tactics for Managing Systena frontalis [F. (Coleoptera: Chrysomelidae)] at Ornamental Nurseries The Red-headed Flea Beetle [Systena frontalis (F.); RHFB] is native to the central and eastern U.S. and has become a costly multivoltine pest of containerized nursery plants. We tested discs of long-lasting insecticidal netting (LLIN) secured over rims of plant containers in spring of 2023, using fo... Sensitivity to imidacloprid insecticide varies among some social and solitary bee species of agricultural value Bioassays using Apis and wild non-Apis species with differing natural histories tested the health effects of sublethal concentrations of imidacloprid on bee longevity and paralysis. Species were chosen for their high abundance and differences in sociality, floral specialization, age, and sex. Throug...

Honey bee Apis mellifera L. responses to oxidative stress induced by pharmacological and pesticidal compounds The western honey bee, Apis mellifera L., is a eusocial insect that plays major roles in ecosystem balances and pollination of plants and food crops. Honey bees face multiple biotic and abiotic stressors, such as pathogens, diseases, chemical pesticides, and climate change, which all contribute to h... Honey bee Apis mellifera L. Responses to Oxidative Stress Induced by Pharmacological and Pesticide Compounds The western honey bee, Apis mellifera L., is a eusocial insect that plays major roles in ecosystem balances and pollination of plants and food crops. Honey bees face multiple biotic and abiotic stressors, such as pathogens, diseases, chemical pesticides, and climate challenges which all contribute ... Evaluation of the efficacy of Steinernema riobrave against Rhipicephalus microplus larvae at semi-field conditions The entomopathogenic nematode, Steinernema riobrave has a moderate impact on larval cattle fever ticks, Rhipicephalus microplus under semi-field conditions. Weekly foliar applications of in vitro reared S. riobrave (BASF – Nemasys-R) applied as spray on tick-infested potted buffelgrass caused signi... Surviving the summer dearth: Managed and wild bees utilize soybeans during a resource poor season Bee declines are being driven by a combination of factors, and some potential responses we can take include establishment of wildflower habitats among croplands and provision of late-season forage when resources are becoming scarce. We tested three trap types and three trap colors for monitoring pol... Herbicide spray drift from ground and aerial applications: Implications for potential pollinator foraging sources A field spray drift experiment using florpyrauxifen-benzyl, a synthetic auxin herbicide, was conducted to measure drift potential of commercial applications from ground and aerial spray equipment, evaluate spray drift impacts on soybean [Glycine max (L.) Merr.], and compare to current United States ... Using the honey bee (Apis mellifera L.) cell line, AmE-711, to evaluate pesticide toxicity Pesticides have been identified as a leading contributor to poor performance and elevated mortality of honey bee colonies in many parts of the world. Exposure of honey bees to pesticides may occur in and around treated landscapes, but also within the hive environment, where pesticide residues may ac...

Pest population dynamics are related to a continental overwintering gradient Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled th... An insight into the microRNA profiles of an ectoparasite mite Varroa destructor (Acari: Varroidae), the primary vector of Deformed Wing Virus (DWV) of the honey bee Apis mellifera L The remarkably adaptive mite Varroa destructor is the most important honey bee ectoparasite. Varroamites are competent vectors of deformed wing virus (DWV), and the Varroa-virus complex is a major determinant of annual honey bee colony mortality and collapse. MicroRNAs (miRNAs) are 22-24 nucleotide ... Traces of a neonicotinoid pesticide stimulate different honey bee colony activities, but do not increase colony size or longevity How neonicotinoid contamination effects honey bees remains controversial. Studies have yielded contradictory results, and few have examined effects on colony development. Here we report the results of a comprehensive five-year study of the effects of the neonicotinoid imidacloprid on honey bee colon... Sublethal concentrations of clothianidin affect honey bee colony growth and hive CO2 concentration The effects of agricultural pesticide exposure upon honey bee colonies is of increasing interest to beekeepers and researchers, and the impact of neonicotinoid pesticides in particular has come under intense scrutiny. To explore potential colony-level effects of a neonicotinoid pesticide at field-re...
