%X This paper reviews recent progress in the research of insect host marking pheromones. Insect host marking pheromones are chemical compounds produced by females and deposited on or into hosts to signal the presence of conspecific brood. The oviposition behavior of females is mediated by host marking pheromones. Females avoid laying eggs on host resources with host marking pheromones to reduce competition among their offspring. Host marking pheromones sometimes may bring adverse effects on the releaser, such as eavesdropping and cleptoparasitism. Host marking pheromones may also play a role in mediating the competition for host resources shared by closely-related species. The interspecific discrimination to host marking pheromones reflects the interspecific competition ability. The sites for production and/ or storage of host marking pheromones are usually associated with either the exocrine, digestive or reproductive systems such as Dufour's gland, poison gland, Malpighian tubules, phrothoracic gland, abdominal gland, mandibular gland, lateral oviduct, ovary, midgut, and hind gut. The host marking pheromones produced usually are deposited into and/or on the hosts by ovipositors, mouthparts or orifices used in defecation. Egg parasitoids tend to mark hosts externally and detect with antennae, while parasitoids utilizing other host stages tend to mark hosts internally and examine with ovipositors. Phytophagous insects deposit host marking pheromones exclusively on the surface of host plants and detect them with antennae and/or ovipositors. Insects use chemoreceptors on ovipositors, mouthparts, antennae or tarsi to detect marking pheromones. The routine of demonstrating the existence of marking pheromone includes isolation, identification, synthesizing of functional chemicals and bioassay. Several host marking pheromones have been isolated and identified.
