Blattella
Blattella is a genus of small cockroaches in the family Ectobiidae, distributed worldwide. The genus includes both domestic pest species, notably the German cockroach (Blattella germanica), and wild species such as the Asian cockroach (Blattella asahinai) and Japanese field roach (Blattella nipponica). Species within this genus exhibit diverse ecological preferences, ranging from human dwellings to outdoor habitats including mountainous regions and field environments.
Lyctini
Powderpost beetles (tribe)
Lyctini is a tribe of wood-boring beetles within the family Bostrichidae, commonly known as powderpost beetles. Members are characterized by their ability to digest cellulose through symbiotic yeasts, enabling them to infest and damage seasoned hardwoods. The tribe includes economically significant pests such as species in the genus Lyctus. These beetles are distinguished from other Bostrichidae by their small size, cylindrical bodies, and reduced elytral declivity.
Pulvinaria
cottony cushion scales, soft scales
Pulvinaria is a genus of soft scale insects (family Coccidae) characterized by females that produce conspicuous cottony or flocculent wax ovisacs to protect their eggs. The genus includes economically significant agricultural and ornamental pests with broad host ranges spanning numerous woody plant families. Several species have invasive potential and have established beyond their native ranges, including P. aurantii, P. psidii, and P. urbicola. The genus exhibits considerable morphological variability, complicating species identification.
