1. A Massive Expansion of Effector Genes Underlies Gall-Formation in the Wheat Pest Mayetiola destructor.

    Current Biology 25(5):613 (2015) PMID 25660540

    Gall-forming arthropods are highly specialized herbivores that, in combination with their hosts, produce extended phenotypes with unique morphologies [1]. Many are economically important, and others have improved our understanding of ecology and adaptive radiation [2]. However, the mechanisms th...

  3. A genome-wide survey of small interfering RNA and microRNA pathway genes in a galling insect.

    Journal of Insect Physiology 59(3):367 (2013) PMID 23232437

    Deployment of resistance (R) genes is the most effective control for Hessian fly, Mayetiola destructor (Say); however, deployment of R genes results in an increased frequency of pest genotypes that display virulence to them. RNA interference (RNAi) is a useful reverse genetics tool for studying ...

  5. Population structure and the colonization route of one of the oldest North American invasive insects: stories from the worn road of the Hessian fly, Mayetiola destructor (Say).

    PLoS ONE 8(3):e59833 (2013) PMID 23544103 PMCID PMC3609732

    An integral part to understanding the biology of an invasive species is determining its origin, particularly in pest species. As one of the oldest known invasive species, the goals of this study were to evaluate the evidence of a westward expansion of Hessian fly into North America, from a poten...

  7. Population structure and spatial influence of agricultural variables on Hessian fly populations in the southeastern United States.

    Environmental Entomology 40(5):1303 (2011) PMID 22251741

    Population structure dictates the evolution of each population, and thus, the species as a whole. Incorporating spatial variables with population genetic statistics allows for greater discovery beyond traditional population genetics alone and can inform management decisions. The understanding o...

  9. Virulence in Hessian fly (Diptera: Cecidomyiidae) field collections from the southeastern United States to 21 resistance genes in wheat.

    Journal of Economic Entomology 103(6):2229 (2010) PMID 21309248

    Genetic resistance in wheat, Triticum aestivum L., is the most efficacious method for control of Hessian fly, Mayetiola destructor (Say) (Diptera: Cecidomyiidae). However, because of the appearance of new genotypes (biotypes) in response to deployment of resistance, field collections of Hessian ...

    Genetics 184(3):769 (2010) PMID 20026681 PMCID PMC2845344

    Two nonoverlapping autosomal inversions defined unusual neo-sex chromosomes in the Hessian fly (Mayetiola destructor). Like other neo-sex chromosomes, these were normally heterozygous, present only in one sex, and suppressed recombination around a sex-determining master switch. Their unusual pro...

    Toxicon 55(2):298 (2010)

    Neurotoxic and cytotoxic effects of venoms from Scorpio maurus palmatus taken from different populations were assessed for geographic based variability in toxicity, and to evaluate their insecticidal potency. Scorpions were collected from four regions. Three locations were mutually i...
