Several yellowjacket species are important pests in both their native habitat and in areas where they are invasive. Traps that contain one or more chemical attractants to lure insects inside are commonly used to combat these yellowjackets in urban environments. Usually, attractants are placed within the trap and combined indiscriminately, though little is known about how this design influences ...

The bibionid fly Plecia nearctica Hardy, commonly called the ‘lovebug’, is a widely recognized insect found alongside roadways in all southern states bordering the Gulf of Mexico as well as Georgia, and North and South Carolina (Denmark et al. 2010). In Florida, descriptions of this insect in large numbers coincide with peak seasonal flight periods in Apr-May and Aug-Sep, with a smaller third f...

Females of Cylindrocorpus longistoma and C. curzii excrete attractants which probably function to bring the sexes together before mating. Intraspecific and interspecific heterosexual and homosexual pairing experiments showed the attractants to be species specific as well as sex specific. Observations on mating behavior support the hypothesis that sexual attraction and copulation require indepen...

Animals can be innately attracted to certain odorants. Because these attractants are particularly salient, they might be expected to induce relatively strong responses throughout the olfactory pathway, helping animals detect the most relevant odors but limiting flexibility to respond to other odors. Alternatively, specific neural wiring might link innately preferred odors to appropriate behavio...

L ike the proverbial donkey that follows the carrot, tumor cells follow chemical attractants. Unlike the donkey, however, the tumor cells even make their own carrots, according to a report The group was interested in how tumor cells migrate to lymphatic vessels—the fi rst step in malignancy for most carcinomas. Migrating tumor cells express receptors for attractants that lym-phatics normally pr...

Networks of protoplasmic tubes of organism Physarum polycehpalum are macro-scale structures which optimally span multiple food sources to avoid repellents yet maximize coverage of attractants. When data are presented by configurations of attractants and behaviour of the slime mould is tuned by a range of repellents, the organism preforms computation. It maps given data configuration into a prot...

For a hundred years it was known that motile bacteria are attracted to a variety of small organic molecules. However, few scientists were interested in bacterial chemotaxis, probably because they were unwilling to believe that these lowly organisms possessed any capability for information processing or could exhibit even simple forms of behavior. Despite evidence to the contrary, it was general...

Abstract Wildlife tourism can have adverse effects on the behaviours and movements of animals, with implications for health fitness individuals populations. We used acoustic-tracking to show that food-based attractants in shark-tourism increases activity (15%) burst (60%) yellowtail kingfish (Seriola lalandi, n = 18). Increased was restricted periods when were same side island group as berleyin...
