methoprenen.

Brit.

/ˈmɛθə(ʊ)priːn/, U.S.

/ˈmɛθəˌprin/

Origin: Formed within English, by compounding. Etymons: methyl n., isoprene n.

Etymology: < meth- (in methyl n.: see note s.v. meth- comb. form) + -oprene (in isoprene n.).

Chemistry.

A sesquiterpenoid analogue of juvenile hormone that prevents the maturation of insect eggs and larvae and is used for the control of mosquitoes, fleas, and certain agricultural pests; propyl 2-(3,7,11-trimethyl-11-methoxydodec-2-4-dien)oate, C₁₉H₃₄O₃.
