Bionomics of two aspen bark beetles, Trypophloeus populi and Procryphalus mucronatus (Coleoptera: Scolytidae)

Beetles of Trypophloeus populi attacked green bark of unhealthy aspen ( Populus tremuloides ) and hastened the death of the tree. Beetles of Procryphalus mucronatus favored dead bark and were of little significance in the death of the aspen. These two beetle species were distinguished from each other by their primary galleries, eggs, larvae, larval mines, and mating behavior. In T. populi, there were three larval instars and one to one and one - half generations per year; only larvae overwintered, and the eggs of the first generation were present by mid - July. In P. mucronatus, there were two larval instars and one and one - half to two generations per year; both larvae and adults overwintered, and the first eggs of the new season were present by late May.

A search for characters to make the generic classification of Platypodidae more nearly objective resulted in the discovery of new anatomical features that appear to reflect patterns in phylogeny for this family. The Platypodidae are members of the Curculionoidea and are very closely allied to Scolytidae. Three subfamilies of Platypodidae are recognized: (1) Coptonotinae, containing Coptonotini ( Coptonotus Chapuis, Protohylastes Wood, Scolytotarsus Schedl), Mecopelmini ( Mecopelmus Blackman, Protoplatypus Wood), and Schedlarini ( Schedlarius Wood [= Chapuisia Dugès]); (2) Tesserocerinae, containing Diapodini ( Diapus Chapuis, Genyocerus Motschulsky [= Diacavus Schedl], and Tesseroccrini ( Platytarsulus Schedl, Notoplatypus Lea, Tesserocranulus Schedl, Tesserocerus Saunders [= Damicerus Spinola, Tesseroplatypus Schedl, Tesserocephalus Schedl]), Spathidicerus Chapuis, Periommatus Chapuis [= Asetus Nunberg, Setanus Nunberg], Chaetastus Nunberg [= Symmerus Chapuis], Cenocephalus Chapuis, and Mitosoma Chapuis [= Platypicerus Nunberg, Coecephalonus Schedl]); and (3) Platypodinae, containing Platypodini ( Platypus Herbst [= Cylindra Illiger, Stenoplatypus Strohmeyer, Platypinus Schedl, Austroplatypus Browne], Treptoplatypus Schedl, Crossotarsus Chapuis, Trachyostus Schedl, Neotrachyostus Browne, Platyscapulus Schedl [= Platyscapus Schedl, Costaroplatus Nunberg], Baiocis Browne, Cylindropalpus Strohmeyer, Triozastus Schedl, Mesoplatypus Strohmeyer, Doliopygus Schedl [= Scutopygus Nunberg, Pygodolius Nunberg, Mixopygus Nunberg, Mesopygus Nunberg], and 11 genera named as new to science derived from the genus Platypus of Schedl 1972. The following are new genera and their type-species: Peroplatypus (for Platypus truncatipennis Schedl), Dinoplatypus (for Platypus cupulatus Chapuis), Myoplatypus (for Bostrichus or Paltypus flavicornis Fabricius), Oxoplatypus (for Scolytus or Platypus quadridentatus Olivier), Platyphysus (for Platypus obtusus Chapuis), Megaplatypus (for Platypus dentatus Dalman), Euplatypus (for Bostrichus or Platypus parallelus Fabricius), Epiplatypus (for Platypus desceptor Wood), and Teloplatypus (for Platypus concinnus Blandford). The archaic ""sektionen"" used by Schedl in his 1972 classification of this family are eliminated. A key for the identification of genera, a discussion of characters, and remarks on phylogeny are included.     

The bark and ambrosia beetles of the Cook Island and Niue (Coleoptera: Scolytidae and Platypodidae)

Twenty-two species of Scolytidae (including one new species), and one species of Platypodidae are recorded from the Cook Islands and Niue in the South Pacific, and a key is given to all species. Corrections are made to earlier records from the islands. Xyleborinus perexiguus (Schedl) comb. n. is transferred from Xyleborus. The faunal composition, breeding habits and geographical distribution of the species are discussed and related to those of other islands in the Pacific. Many species have probably been introduced by man. In the absence of a major timber industry, the species are likely to be of minor economic importance.
