Monitoring and management of thrips populations in vegetables, row crops, and greenhouse crops in Virginia
… thrips. The lures included Chemtica P-178 floral kairomone (AgBio Inc., Westminster, CO), a floral iii kairomone lure composed of a proprietary floral compound mixture, and ThriplineAMS (Syngenta Bioline Ltd., Oxnard, CA) pheromone lure, containing the aggregation pheromone of F. occidentalis. In …

The investigation of kairomones and photosensitizers affecting Liriomyza bryoniae (Diptera, Agromyzidae) /
… volatiles, such plant-origin compounds (kairomones) could be used for insects’ attraction to the bait with photosensitizer. The aim of the study was to determine kairomones emitted by tomato leafminer L. bryoniae host-plants and investigate the effect of photosensitizers on tomato …

Use of magnetic and olfactory cues for orientation by a fossorial rodent, Thomomys talpoides
… in T-maze trials with soils containing carrot kairomone versus control soil. Binomial probability analysis revealed in all tests comparing carrot soil vs. control that gophers disproportionally selected the carrot soils. Overall my study suggests T talpoides can use both magnetic and olfactory …

Communication in the hymenoptera : chemistry, ecology and evolution
… (Z)-11- eicosen-1-ol plays a crucial role as kairomone for prey identification of honeybees by beewolf females. Third, a reanalysis of the beewolf male sex pheromone shows a remarkable similarity of compounds between the pheromone and the honeybee cuticle, besides the co-occurrence of …

Factors affecting the response of thrips to an olfactory cue
… studies undertaken previously using MI-based kairomone lures have shown large variations in trapping efficacy both within and between different trials. Most notable were results from southeast Spain where there appeared to be an overall lack of effect. Specific objectives include examination …

Investigation of dried distillers grains with solubles (DDGS) susceptibility to red flour beetle (Tribolium castaneum (Herbst)) infestation
… when a combination of DDGS and food oil kairomone lures were used compared with food oil or empty traps. Therefore, DDGS may be a good additive to food oil lures to increase trap efficacy. In conclusion, <em>T. castaneum</em> development significantly increased when fed DDGS. Diet …

Phenotypic plasticity from a predator perspective: empirical and theoretical investigations
… an inducible prey defense. Lembadion releases a kairomone (i.e. an infochemical) that induces defenses in several prey species. For example, in the herbivorous ciliate Euplotes octocarinatus, it triggers the production of protective lateral "wings". I show that Lembadion can reduce the effect of …

Orientation of polyphagous lepidoptera to hostplant kairomones
… in some oligophagous lepidopterans oviposition kairomones from hostplants can also serve as larval feeding stimulants, the relationships in chemistry of attraction of larval and adult stages to hostplants have rarely been examined in polyphagous species. Volatile constituents are known to serve …

Investigations of the integrated pest management of Colorado potato beetle, Leptinotarsa decemlineata (Say): Host plant preference, development of semiochemical-based strategies, and evaluation of a novel insecticide
Exploiting the chemical ecology of an insect can unveil novel strategies for its pest management. Though much has been learned about the chemical ecology of Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), a major pest of solanaceous crops in the U.S., …

Aggregation, dispersal and edge behavior of the bark beetle predator Thanasimus dubius (Coleoptera: Cleridae); potential use in biological control
… after having experienced conditioning with this kairomone via a reward. Finally, experiments on dispersal and edge behavior revealed that T. dubius and one of its common prey, the bark beetle I. grandicollis, exhibit a different pattern of movement within red pine stands and surrounding habitats. …
