BACKGROUND This is the third in a series of papers detailing the terrestrial arthropods collected during an intensive survey of a site near Steel Creek campground along the Buffalo National River in Arkansas. The survey was conducted over a period of eight and a half months using twelve trap types - Malaise traps, canopy traps (upper and lower collector), Lindgren multifunnel traps (black, gree...

Current hypotheses propose that, in the invertebrates, neuropeptide F (NPF), the vertebrate NPY homologue, may be capable of regulating responses to diverse cues related to nutritional status and feeding. An investigation into the effects of Drosophila melanogaster NPF (DrmNPF) and Anopheles gambiae NPF (AngNPF) on hindgut physiology of Rhodnius prolixus Stal (Heimptera: Reduviidae) suggests a ...

Next-generation sequencing data analysis on Triatoma infestans Klug, 1834 (Heteroptera, Cimicomorpha, Reduviidae) revealed the presence of the ancestral insect (TTAGG)n telomeric motif in its genome. Fluorescence in situ hybridization confirms that chromosomes bear this telomeric sequence in their chromosomal ends. Furthermore, motif amount estimation was about 0.03% of the total genome, so tha...

The corn leafhopper Dalbulus maidis (Hemiptera: Cicadellidae), is an important corn pest in most of tropical and subtropical America. This leafhopper has a rich natural enemy complex of which parasitoids and pathogens are the most studied; knowledge on its predators is limited. We noted the presence of the native assassin bug Zelus obscuridorsis (Hemiptera: Reduviidae) predating diverse motile ...

Parasites have been shown to manipulate the feeding behaviour of their invertebrate vectors, which results in an increased probability of transmission to definitive hosts. Most evidence for this hypothesis comes from protozoan species with salivary transmission but evidence for stercorarian parasite transmission is lacking. We present experimental evidence that infection of the kissing bug Mepr...

A new species of Stenolemus Signoret, 1858, Stenolemus annulatus sp. nov. (Reduviidae: Emesinae) is described from India. This new species is closely related to S. susainathani Wygodzinsky from Nilgiri Hills, South India and S. larat Wygodzinsky from Moluccas, Larat, by sharing common characteristics such as the ratio of distance between eyes and their width, long antennal first segment, slight...
