American cockroaches are an important source of household allergens in tropical and semitropical climates. To determine which outdoor niches produce American cockroaches, traps were placed at 40 homes in New Orleans to collect nymphs. Nymphs were collected from the sewers, yards, and within the homes themselves. To compare sewers and yards as sources of cockroaches entering homes, adult cockroaches were collected, marked, and released into yards and sewers. No sewer-released cockroaches were collected in homes. Cockroaches released into yards were collected in the homes, suggesting that yards, rather than sewers, are a more important source niche. A field trial applying boric acid granules to the yard was performed in an effort to reduce entry of cockroaches. There was a significant reduction in the cockroach antigen collected in intervention homes compared with controls.

Insects are known invertebrate species with economic, ecological, pathological, and medicinal value, as well as closely associated with human populations. Entomophagy and entomotherapy are future promising prospects largely attributable to the abundant availability, high protein content, and climatic sustainability of insects. In particular, the insect brain is an important system with a secluded, compact, and protective exoskeleton.

The American cockroach Periplaneta americana (L.) (Blattodea, Blattidae) has been a model organism for biochemical and physiological study for almost a century, however, its use does not benefit from the genetic tools found in key model species such as Drosophila melanogaster. To facilitate the use of the cockroach as a model system in neuroscience and to serve as a foundation for functional and translational experimentation, a transcriptome of the cephalic ganglia was assembled and annotated, and differential expression profiles between these ganglia were assessed.

Ischemic stroke (IS) is a highly lethal type of cardiovascular and cerebrovascular disease. Improving survival rates and promoting recovery in patients with IS pose significant challenges, however, recent research has identified the gut-brain axis as a therapeutic target. In this study, we evaluated the regulatory effect of (L.

Infected wounds caused by bacteria commonly cause delayed wound healing and even serious tissue damage, evolving into one of the most problematic clinical issues. Traditional therapies and wound dressings cannot achieve either the ideal antibiotic activity or the accelerated wound healing outcomes. Based on our previous finding that glycoproteins (PAGP) derived from medicinal animal insect Periplaneta americana L.

Background: Insect-associated actinomycetes represent a potentially rich source for discovering bioactive metabolites. However, the diversity, antibacterial and phytotoxic activities of symbiotic actinomycetes associated with have not yet been conducted.
Results: A total of 86 strains of actinomycetes were isolated from the cornicles and intestines of both nymphs and adults of .
