Insect repellent textiles offer protection against disease-causing vectors such as mosquitoes, flies, and ticks. Protection is based on the incorporation of insect compounds present in plant oil derivatives or synthetic oils. The effectiveness application natural repellents citronella grass, lemongrass, rosemary, peppermint, holy basil, tea tree, neem, lavender, thyme, lemon eucalyptus, clove, ...

We tested toxins of Bacillus thuringiensis against larvae from susceptible, Cry1C-resistant, and Cry1A-resistant strains of diamondback moth (Plutella xylostella). The Cry1C-resistant strain, which was derived from a field population that had evolved resistance to B. thuringiensis subsp. kurstaki and B. thuringiensis subsp. aizawai, was selected repeatedly with Cry1C in the laboratory. The Cry1...

In a recent paper a new subfamily of Psychodidae was inadequately named Protopsychodinae. This nomenclatural act cannot be considered as a valid name under ICZN regulations because the subfamily name is not based on the type genus Datzia Stebner et al., 2015, and furthermore the fossil genus Protopsychoda Azar et al., 1999 was originally described under the subfamily Psychodinae. Therefore, the...

Barrier islands are complex and dynamic systems that provide critical ecosystem services to coastal populations. Stability of these systems is threatened by rising sea level and the potential for coastal storms to increase in frequency and intensity. Recovery of dune-building grasses following storms is an important process that promotes topographic heterogeneity and long-term stability of barr...

Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system.  Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...

Beetles in the genus Tetraopes share a long evolutionary history with milkweeds (Asclepias spp.), feeding on roots as larvae and leaves as adults. Despite their extreme specialization on milkweed, Tetraopes require drying grass stems as oviposition sites, even though they do not consume grass. The natural history of the interaction suggests that herbivory may be likely only when milkweeds are i...
