Exempel på hur man kan använda ATTRACTANTS i en mening

• Nepetalactones are cat attractants, and cause the behavioral effects that catnip induces in domestic cats.
• Studies in multiple organisms including, mice, rats, chicks, the nematode Caenorhabditis elegans, the fruit fly Drosophila melanogaster and the zebrafish Danio rerio have indicated that secreted netrins are bifunctional, meaning that they can act as either attractants or repellants in directing axonal extension.
• It is usually used in the field of chemical ecology to encompass pheromones, allomones, kairomones, attractants and repellents.
• An increase in concentration of attractants led to an increase in methylation level of MCP; similarly, a decrease in attractants or increase in repellents led to a decrease in methylation level.
• Chemical probes of bacterial signal transduction reveal that repellents stabilize and attractants destabilize the chemoreceptor array.
• In at least species that are attracted to prey of Nephilinae in Florida, the major attractants released by Heteropteran prey appear to be low-molecular-weight carbonyl compounds, among which trans-2-hexenal and hexanal are prominent.
• Although they are not produced by the cat themselves, and therefore are not pheromones, cat attractants are semiochemical odorants that have an effect on cat behavior and can be used for environmental enrichment.
• Rivnay on the possible utilization of insect attractants and repellents for suppressing the density of harmful insect populations, particularly in the phytophagous cotton leafworm Spodoptera littoralis (Noctuidae, Lepidoptera), the haematophagous bedbug Cimex lectularius (Cimicidae, Hemiptera) and the cereal feeding khapra beetle Trogoderma granarium (Dermestidae, Coleoptera).
• Aerotaxis, similar to other types of bacterial taxis, involves repeated cycles of straight-line swimming followed by short reversals that reorient bacteria so that they are constantly drawn up their oxygen gradients toward attractants and away from repellants.
• Trails laid with the sternal glands, relatively short-lived, serve to recruit nestmates to food patches, while secretions from the pygidial gland release attractants to food at short range (up to 15 cm).
• Orchids in the genus Pterostylis have been found to attract male fungus gnats with chemical attractants and then trap them using a mobile petal lip.
• Baker is an American entomologist, focusing in study of insect pheromones and odor-mediated behavior, neuroethological studies of olfaction, identification and development of insect attractants for IPM systems, and development of olfaction-based biosensors and chemical ecology, currently Distinguished Professor at Pennsylvania State University and an Elected Fellow of the American Association for the Advancement of Science.
• The objectives of meliponiculture are to produce and sell hives (or parts of them), honey, pollen, resins, propolis, wax, and other substrates such as attractants and trap nests; in addition to the ecosystem service of pollination itself, since bees are one of the main agents of pollination and the maintenance of biodiversity.
• Additionally, certain species of Bulbophyllum attract specific male Dacini fruit flies through particular male attractants such as methyl eugenol (ME), raspberry ketone (RK), or zingerone (ZN).
• These classes of pheromonal action are the opposite-sex attractants, the same-sex repellants (territorial markers), mother–infant bonding attractants and those modulating the timing of the fertile cycle.
• Bossert introduced the term releaser and primer pheromones for this purpose, to distinguish the behavior-controlling effect of, for example, sex attractants from the pheromones that interfere with the endocrine system of the receiver.
