Amblyseius andersoni
Amblyseius andersoni is a generalist predatory mite in the family Phytoseiidae, widely distributed across Europe, North America, and parts of Asia. It is commercially available and employed as a biological control agent against spider mites, eriophyid mites, and other small arthropod pests in orchards, greenhouses, and open-field crops. The species exhibits broad dietary flexibility, feeding on plant-feeding mites, thrips, whiteflies, and various pollens. Laboratory studies demonstrate that it can be mass-reared on alternative diets such as cattail pollen and the stored product mite Carpoglyphus lactis without loss of predatory efficiency on natural prey.

Franklinothrips is a pantropical genus of predatory thrips in the family Aeolothripidae, comprising 14 recognized species. The genus is distinguished by striking ant-mimicry, particularly in females, which exhibit fast-running behavior and body forms resembling ants or bethylid wasps. Most species are bisexual with localized distributions, though F. vespiformis is notably unisexual and widespread. Several species have been developed as biological control agents against pest thrips in greenhouses and agricultural systems.
Franklinothrips vespiformis
Vespiform Thrips, Vespiform Thrip
Franklinothrips vespiformis is a predatory thrips species in the family Aeolothripidae, notable for its ant-mimicking adult morphology and distinctive red, humped-back larvae. It is widely distributed across tropical and subtropical regions worldwide and has been extensively studied as a biological control agent for various agricultural and greenhouse pests. The species exhibits myrmecomorphy—mimicking ants in appearance and fast, erratic movement behavior—which likely serves as a defense against predation. It is primarily parthenogenetic, with males being rare.
