Chemical defense in harvestmen (Arachnida, Opiliones): Do benzoquinone secretions deter invertebrate and vertebrate predators?
(Springer, 2005-11)
Two alkylated 1,4-benzoquinones were identified from the defensive secretion produced by the neotropical harvestman Goniosoma longipes (Gonyleptidae). They were characterized as 2,3-dimethyl-1,4-benzoquinone and ...
Composition and biological activity of essential oils from Labiatae against Nezara viridula (Hemiptera: Pentatomidae) soybean pest
(John Wiley & Sons Ltd, 2011-08)
BACKGROUND: Plant essential oils have been recognised as an important natural source of insecticide. This study analysed the chemical constituents and bioactivity of essential oils that were isolated via hydrodistillation ...
Foraging experience modulates response to aversive odour cues in social wasps
(Academic Press Ltd - Elsevier Science Ltd, 2020-06)
Experience can modify how animals respond to relevant stimuli from their environment, for example, through associative learning. In particular, odour stimuli play a central role in foraging by influencing decision making. ...
Superconducting heterostructures: From antipinning to pinning potentials
(IOP Publishing, 2014-07)
We study vortex lattice dynamics in a heterostructure that combines two type-II superconductors: a niobium film and a dense triangular array of submicrometric vanadium (V) pillars. Magnetic ac susceptibility measurements ...
Thymol bioactivity: A review focusing on practical applications
(Elsevier, 2020-12)
Thymol is a natural volatile monoterpenoid phenol that is the main active ingredient of oil extracted from species Thymus vulgaris L., commonly known as thyme, and other plants such as Ocimum gratissimum L., Origanum L., ...
PH-responsive ion transport in polyelectrolyte multilayers of poly(diallyldimethylammonium chloride) (PDADMAC) and poly(4-styrenesulfonic acid-co-maleic acid) (PSS-MA) bearing strong- and weak anionic groups
(Royal Society of Chemistry, 2015-10)
The layer-by-layer construction of interfacial architectures displaying stimuli-responsive control of mass transport is attracting increasing interest in materials science. In this work, we describe the creation of interfacial ...
Defying Coulomb's law: A lattice-induced attraction between lithium ions
(Pergamon-Elsevier Science Ltd, 2018-11)
Normally ions with the same charge repel each other, but in very rare cases an intervening medium can produce an apparent attraction. We have studied the adsorption of Li-ions on semiconducting carbon nanotubes by density ...
Invasive exotic grasses and seed arrival limit native species establishment in an old-field grassland succession
(Springer, 2012-12)
Plant communities developing in abandoned semi-natural areas are being increasingly dominated by invasive exotic species. How these 'novel residents' affect re-colonisation by native perennial species, a process generally ...
International recommendations for an effective control of head louse infestations
(Wiley Blackwell Publishing, Inc, 2020-08)
Head louse infestations continue to be a concern of public health in most countries, including the most developed ones. The present recommendations are intended to inform and stress the role and impact of the different ...
Effects of Butylated Hydroxytoluene (BHT) on Tribolium confusum (Coleoptera: Tenebrionidae)
(South Carolina Entomological Soc, 2021-11-22)
The objective of this study was to evaluate different doses of butylated hydroxytoleuene (BHT) against the confused flour beetle, Tribolium confusum Jacquelin du Val (Coleptera: Tenebrionidae). The effects on feeding ...
