Chamaesphecia empiformis on a red rubber septum pheromone lure. A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure is encased in a conventional trap such as a bottle trap, delta trap, water-pan trap, or funnel trap.

A pheromone (from Greek phero "to bear" + hormone from Greek – "impetus") is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual. [ 5 ]
Bedbug nymphs protect themselves with such a pheromone, which has a specific mixing ratio of the aldehydes -2-hexenal, -2-octenal and 4-oxo--2-hexenal, against mating attempts by male bedbugs. The latter directly drills a hole into the abdomen of sexually mature female bedbugs and injects its sperm there ( traumatic insemination ).
Androsterone, or 3α-hydroxy-5α-androstan-17-one, is an endogenous steroid hormone, neurosteroid, and putative pheromone. [1] It is a weak androgen with a potency that is approximately 1/7 that of testosterone. [2] Androsterone is a metabolite of testosterone and dihydrotestosterone (DHT).
Androstadienone, or androsta-4,16-dien-3-one, is a 16-androstene class endogenous steroid that has been described as having potent pheromone-like activities in humans. [1] The compound is synthesized from androstadienol by 3β-hydroxysteroid dehydrogenase, and can be converted into androstenone (a more potent and odorous pheromone) by 5α-reductase, which can subsequently be converted into 3α ...
In July 2009, the university college had the first batch of the programmes of study approved by Senate at the University of Nairobi. [10] The curricula are in the areas of electrical and electronic engineering and comprise the Bachelor of Engineering (B. Eng. in Electrical and Electronic Engineering, Bachelor of Technology (B.Tech.) in Electrical and Electronic Engineering Technology, and the ...
Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species.
