9-(Z)-Pentacosene is a olefin that can be isolated from Fannia canicularis. 9-(Z)-Pentacosene has anti-insect activity.

(Z)-9-Nonadecene is the anal secretion of a species of thrips.

(3E,5E,7E,9E)-5.7-Diethyl-9-methyl-3,5.7,9-tetracontatriene (Compound 9) is an insect pheromone (male C. dimidiatus).

(7Z)-7-Tricosene is a pheromone and can be produced by Aleochar curtula.

(3E)-4,8-Dimethylnona-1,3,7-triene, a sesquiterpene, is the major herbivore-induced plant volatile that help in defense directly by acting as repellants and indirectly by recruiting insects' natural enemies. (3E)-4,8-Dimethylnona-1,3,7-triene attractes Asian corn borer (ACB, Ostrinia furnacalis) larvae. External supplementation with (3E)-4,8-Dimethylnona-1,3,7-triene hampered the larvae's ability to locate pre-infested maize.

(E,E)-4,8,12-Trimethyl-1,3,7,11-tridecatetraene (TMTT), a sesquiterpene, is the major herbivore-induced plant volatile that help in defense directly by acting as repellants and indirectly by recruiting insects' natural enemies. (E,E)-4,8,12-Trimethyl-1,3,7,11-tridecatetraene attractes Asian corn borer (ACB, Ostrinia furnacalis) larvae. External supplementation with (E,E)-4,8,12-Trimethyl-1,3,7,11-tridecatetraene hampered the larvae's ability to locate pre-infested maize.

Tetratriacontane is an ester product.

6(Z),9(Z)-Tricosadiene is an ester product.

Pentatriacontane is an ester product.

Eicosane is an alkane with anti-microbial effects. Eicosane inhibits the growth of B. subtilis, E. coli and P. aeruginosa. Eicosane is used to form candles.

2-Methylhexacosane is a saturated hydrocarbon and an insect pheromone. It has been found in the cuticle of M. dasystomus females, but not males, where it contributes to the mating behavior of males, as well as in D. melanogaster females where it modulates aggression of males towards females. 2-methylhexacosane has also been found in yellow jacket (V. vulgaris) trail extracts.

Geranylacetone is a natural compound isolated from the stems of Ferula akitschkensis.
