Bed bug aggregation pheromone finally identified.

Angewandte Chemie, 2015
AbstractBed bugs have become a global epidemic and current detection tools are poorly suited for routine surveillance. Despite intense research on bed bug aggregation behavior and the aggregation pheromone, which could be used as a chemical lure, the complete composition of this pheromone has thus far proven elusive.

The male-produced aggregation pheromone of the bean flower thrips Megalurothrips usitatus in China: identification and attraction of conspecifics in the laboratory and field.

Pest Management Science, 2020
BACKGROUND Thrips, Megalurothrips usitatus, usually display aggregation behavior, which is probably mediated by a male-produced aggregation pheromone. Aggregation pheromones are species-specific, and can be used to develop commercial lures for monitoring

Plasticity of aggregation pheromones in insects

Current Opinion in Insect Science, 2023
Pheromone plasticity is widely observed in insects and enhances their survival, adaptation, and reproductive success. Aggregation pheromones, which cause notable individual aggregation and consequently impact agriculture and human life, are renowned for their special function.

Cockroach aggregation pheromone: Directional orientation

Behavioral Biology, 1973
Orientation of adult and immature cockroaches, Periplaneta americana, in a T-maze is directed by a feces-secreted aggregation pheromone. Tropochemotactic orientation is dependent on olfactory perception of the pheromone by antennal receptors.

Aggregation pheromones in Collembola

Journal of Insect Physiology, 1977
Abstract The existence of aggregation pheromones is demonstrated in the Collembola Orchesella cincta, Orchesella villosa , and Tomocerus minor . Places conditioned by these animals can be considered as pheromone-sources, causing aggregation. Although for Tomocerus minor perception is not strictly species specific, all species investigated appear ...

Anthonomus grandis aggregation pheromone induces cotton indirect defence and attracts the parasitic wasp Bracon vulgaris

Journal of Experimental Botany, 2019
Insect-derived volatiles seem to provide reliable chemical cues that plants could employ to defend themselves. Here we investigated the effect of pheromone emission from a closely associated (Anthonomus grandis; boll weevil) and an unassociated (Tibraca ...

Aggregation pheromones inDrosophila borealis andDrosophila littoralis

Journal of Chemical Ecology, 1988
Mature males ofDrosophila borealis andD. littoralis (Diptera: Drosophilidae) produce pheromones that attract both males and females in a wind-tunnel bioassay. Ethyl tiglate is a major pheromone component in both species. Isopropyl tiglate is a minor component, as active as ethyl tiglate on an equal-weight basis, but less abundant in the flies.

Aggregation Pheromone of Pityokteines elegans

Journal of Chemical Ecology, 1997
In laboratory bioassay experiments, the beetles Pityokteines elegans were attracted to volatiles captured from bolts of grand fir, Abies grandis, colonized by P. elegans males. Male-specific volatiles detected by coupled gas chromatographic–electroantennographic detection (GC-EAD) analysis and by GC–mass spectrometry employing a chiral column were: (S)-

Aggregation Pheromone Density Based Classification

2008 International Conference on Information Technology, 2008
Social insects like ants, bees deposit pheromone (a type of chemical) in order to communicate between the members of their community. Pheromone, that causes clumping behavior in a species and brings individuals into a closer proximity, is called aggregation pheromone.

Aggregation Pheromone Density Based Clustering

9th International Conference on Information Technology (ICIT'06), 2006
Ants, bees and other social insects deposit pheromone (a type of chemical) in order to communicate between the members of their community. Pheromone that causes clumping or clustering behavior in a species and brings individuals into a closer proximity is called aggregation pheromone. This paper presents a new algorithm (called APC) for clustering data
