* Research allelochemicals and write a report on one type of allelochemical interaction that is beneficial to the plant and detrimental to a pest (kairomone or allomone
It has been suggested that the longer-chained aliphatic acids found in arthropod allomone
blends serve to improve the penetration of the shorter-chained acids (Eisner et al., 2005).
At least one species of nudibranch incorporates a defensive allomone
into its benthic spawn mass (12), although the location within eggs or extraembryonic investments is unknown.
In the eastern lubber grasshopper, Romalea microptera (Beauvois), the secretion contains a mixture of chemicals such as various phenols and quinones, plant derived allomones
, and the sesquiterpenoid, romallenone, but the exact mixture of these chemicals is variable among individuals (Jones et al.
in the three species of Hypselodoris (Gastropoda: Nudibranchia) from the Cantabrian Sea.

, either as suppressants, deterrents or anorexigenics (Warthen and Morgan 1990).
This observation implies that the solo guppies are responding to a chemical signal given off by a "scared" guppy or to chemical signals, called allomones
, given off by an anticipatory predator.

of the fire bee, Trigona (Oxytrigona) mellicolor.
Some terpenes are used by insect pests as precursors for essential messenger molecules (allomones
tabaci adult's ability to react to plant substances (Walker and Gordh 1989) as well as the types of allomones
to which they could respond (Warthen and Morgan 1990) and how their effects could be recognized (Walker and Perring 1994) have been discussed elsewhere (Flores et al.
