Arrestant pheromone /Aggregation arrestant pheromone:pheromone resources



Arrestant pheromone /Aggregation arrestant pheromone



Aggregation arrestant pheromone:

Aggregation behavior and reduced locomotory activity in the German cockroach is caused  by chemical compounds in the feces  (mixture of six carboxylic acids out of a total of 29) and a steroid glucoside denoted as blattellastanoside A, which has been suggested as an aggregation arrestant pheromone in Blattella germanica (Jürgen Scherkenbeck et al., 1999).


Hydroquinone found in the labial glands of a number of termite species acts as a primary phagostimulating factor, but, instead may act as a repellent at higher concentrations. The attractant/arrestant of the Formosan termitemay have multiple components of which hydroquinone, at low doses, could be one (Ashok k. Raina,2005).


Behavioral responses to an extract of aggregated mites were compared to 30 common mite (Dermatophagoides farinae Hughes) attractants identified in cuticular lipids, excretory products and mammalian skin in a refined two-choice bioassay. None of the mite-derived chemicals, including the extract, displayed significant attraction activity. Mammalian skin lipids serve as food attractants for house dust mites. Clustering is most likely due to the physical presence of an inanimate object or another mite's body without the involvement of arrestant-aggregation pheromones (Emmett V. Glassa et al.,2001).


Arrestant pheromone:
Arrestment (=assembly) is defined as the cessation of kinetic activity, a response that reduces the distancebetween individuals that perceive the stimulus in their environment (Carde´ and  Baker, 1984) and leads to clusters of individuals in their natural environment.

Female, male, and juvenile firebrats, Thermobia domestica (Packard) (Thysanura: Lepismatidae), employ a pheromone that arrests conspecifics on contact. One or more debris components from a T. domestica shelter constitute the source of the arrestment pheromone (Nathan Woodbury and  Gerhard Gries, 2008).

Arrestment pheromone are also reported in Argas ticks by Leahy et al.(1973), in Ixodes ricinus (Graf,1978), I. holocyclus and Aponnomca concolor (Treverrow et al.,1977), Hyalomma dromedarii (Leahy et al.,1981), Rhipicephalus appendiculatus and Amblyomma cohaerans (Otieno et al., 1985), R. evertsi (Gothe and  Neitz, 1985), in  soft ticks, Ornithodoros moubata (Leahy et al.,1975), in black-legged deer tick, Ixodes scapularis (Allan  and  Sonenshine, 2002).
