CC   -!- FUNCTION: Represses the synthesis of methyl farnesoate, the precursor
CC       of insect juvenile hormone III in the mandibular organ.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Produced by the medulla terminalis X-organ in the
CC       eyestalks and transported to the sinus gland where it is stored and
CC       released.
CC   -!- SIMILARITY: Belongs to the arthropod CHH/MIH/GIH/VIH hormone family.
CC       {ECO:0000305}.
