Anthocoris nemoralis
Orchard Bug, Pear Bug
Anthocoris nemoralis is a predatory true bug in the family Anthocoridae, native to Europe and introduced to North America. It serves as a dominant natural enemy of pear psylla (Cacopsylla pyri) in European pear orchards and is commercially reared for biological pest control. Adults are approximately 3 mm long, predominantly black with distinctive white markings on the wings. The species exhibits temperature-insensitive predation efficiency, with females demonstrating higher attack rates and shorter handling times than males.
Anthocoris nemorum
Common Flowerbug
Anthocoris nemorum is a predatory anthocorid bug native to Europe, commonly known as the common flowerbug. It is an important biological control agent in orchards and agricultural systems, preying on aphids, psyllids, mites, and other small arthropods. The species exhibits distinct oviposition preferences, laying eggs primarily on apple leaves near leaf margins, and shows preference for damaged leaves over healthy ones. Multiple generations occur annually, with adults overwintering and reproducing in spring.
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.
