The hemolymph of each caste of the primitive dampwood termite Zootermopsis nevadensis (Isoptera, Termopsidae, Termopsinae) contains a high molecular mass lipoprotein which functions as a specific, high affinity carrier for juvenile hormone (JH) III, as detected by JH III‐displaceable covalent modification by the tritium‐labeled photoaffinity analog (10 R )‐10, 11‐epoxyfarnesyl diazoacetate ([ 3 H]EFDA). The Formosan termite Coptotermes formosanus (Rhinotermitidae, Coptotermitinae) and Eastern subterranean termite Reticulitermes flavipes (Rhinotermitidae, Rhinotermitinae) possess analogous proteins. Variations among the major proteins and the JH‐binding lipoproteins are described.
