Campylomma
mullein bugs
Campylomma is a genus of plant bugs (family Miridae, tribe Nasocorini) comprising at least 12 recognized species. The genus is best known from detailed studies of C. verbasci, the mullein bug, which exhibits a predator-phytophage feeding strategy and has been investigated for pheromone-based mating disruption in orchard systems. Japanese species have been taxonomically revised, with emphasis on genitalic characters for identification. The genus occurs across temperate regions of the Northern Hemisphere including North America, Europe, and East Asia.
Campylomma verbasci
mullein bug
Campylomma verbasci, commonly known as the mullein bug, is a plant bug in the family Miridae. It is a predator-phytophage that functions as a biological control agent in orchards, feeding primarily on pear psylla (Psylla pyricola) and European red mite (Panonychus ulmi). The species overwinters as eggs on woody hosts including apple, pear, Rosa spp., and Amelanchier sp., then completes two to four generations annually depending on region. Adults disperse to herbaceous plants, particularly common mullein (Verbascum thapsus), during summer months before returning to orchards in autumn. It has been studied extensively for pheromone-based mating disruption, representing the first documented case of such control in Heteroptera.
