Japanese cockroach

The Japanese cockroach (Periplaneta japonica), also known as the Yamato cockroach,[1] is a cockroach native to Japan that is adapted to cooler northern climates.[2][3][4] It has a flexible univoltine or semivoltine (one or two year) lifecycle, depending on the timing of its hatching, and is unusual in being able to spend two winters as diapause nymphs before reaching maturity.[3]

Freeze tolerance[edit]

Nymphs have been observed in the wild hibernating in sub-freezing temperatures during winter months in snow-covered habitats.[5] Overwintering nymphs were able to survive laboratory supercooling experiments in the -5 °C to -8 °C temperature range, enduring twelve hours of tissue freezing,[6] as well as recover from burial in ice.[1] The ability to walk on ice was also found to be unique among several cockroach species tested.[1]

Physiology[edit]

Initial first-instar nymphs are dark brown, with white or brownish white tips of the maxillary and labial palps. Adults measure 25–35 mm in length, and have a shiny, uniformly black to blackish-brown body, with brown tarsi and maxillary and labial palps. The adult male's wings extend slightly beyond the body's length, while the female's wings are around half the body's length.[7]

Unlike most cockroaches, the major hydrocarbon in P. japonica’s cuticular lipids is cis-9-nonacosene.[8] Males have significant amounts of cis-9-heptacosene not found on females.[8] Glucose, myo-inositol, scyllo-inositol and trehalose were found in overwintering nymphs and are thought to be a factor in their freeze tolerance.[6]

Habitat[edit]

Primarily an outdoors species, populations are adaptable to living indoors in houses and buildings where food is stored, prepared, or served.[7][9]

Defense[edit]

P. japonica nymphs that are alone or in sparse populations accumulate a viscous secretion along its rear dorsal surface, droplets of which it can be splashed some distance toward a threat through a shaking action. A study found that the presence of an aggressive species of ant, Formica exsecta, triggered this defensive response, rendering the ants helpless.[10]

Invasive species[edit]

Originally from Japan, P. japonica has spread to China, Korea and southeast Russia, though it is considered a common pest primarily in central and northern Japan.[4][7][9][11]

The species was found in New York City in 2013, the first time the species was found in the United States.[12] It was found by an exterminator beneath plantings in High Line, a Manhattan park, and was able to survive over a cold winter.[13] Scientists who confirmed the identity of the species through genetic testing theorize that it may have been imported in the soil of ornamental plants used in the park.[12]
