Acrobasis tricolorella
destructive prune worm, tricolored acrobasis moth
Acrobasis tricolorella is a snout moth (Pyralidae: Phycitinae) described by Augustus Radcliffe Grote in 1878. The species occurs in southern Canada and the northern United States. Adults are active from June to October. Larvae feed on buds and fruits of various Rosaceae and related woody plants, and overwinter in the larval stage.
Agrilus sinuatus
sinuate peartree borer, hawthorn jewel beetle
Agrilus sinuatus is a metallic wood-boring beetle in the family Buprestidae, native to Europe and Northern Asia (excluding China) with introduced or established populations in North America. The species has emerged as a significant pest of rosaceous trees in European orchards and nurseries, particularly pear, quince, and hawthorn. It was historically an occasional pest in the 19th century, became rare during the broad-spectrum insecticide era, then resurged dramatically from 1992–1997 in Germany, the Netherlands, and Belgium, with a major population explosion recorded in Hungary in 2019 causing 40–50% tree mortality in a quince orchard. The species exhibits a two-year life cycle with thermophilic tendencies, showing increased population growth following hot summers.
Chaetosiphon thomasi
American Hairy Rose Aphid
Chaetosiphon thomasi is an aphid species in the family Aphididae, commonly known as the American Hairy Rose Aphid. It was described by Hille Ris Lambers in 1953. The species belongs to a genus associated with feeding on Rosaceae plants, particularly roses and strawberries.
