The Japanese cockroach (Periplaneta japonica), also known as the Yamato cockroach, [1] is a cockroach native to Japan, 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]
Initial first-instar nymphs are dark brown, with white or brownish white tips of the maxillary and labial palps. Adults measure 25–35 millimetres (2+1⁄2–3+1⁄2 cm) 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. [5]
Unlike most cockroaches, the major hydrocarbon in P. japonica’s cuticular lipids is cis-9-nonacosene. [6] Males have significant amounts of cis-9-heptacosene not found on females, as do P. australasiae and P. fuliginosa males and females. [6] Glucose, myo-inositol, scyllo-inositol and trehalose were found in overwintering nymphs and are thought to be a factor in their freeze tolerance. [7]
Nymphs have been observed in the wild hibernating in subfreezing temperatures during winter in snow-covered habitats. [8] Overwintering nymphs were able to survive laboratory supercooling experiments in the −5 to −8 °C (23 to 18 °F) temperature range, enduring 12 hours of tissue freezing, [7] 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]
Primarily an outdoors species, populations are adaptable to living indoors in houses and buildings where food is stored, prepared, or served. [5] [9]
A P. japonica nymph alone or in sparse populations accumulates a viscous secretion along its rear dorsal surface, droplets of which it can be splashed some distance toward a threat through a shaking action. The presence of an aggressive species of ant, Formica exsecta , triggered this defensive response, rendering the ants helpless. [10]
Originally from Japan, P. japonica has spread to China, Korea and far eastern Russia, though it is considered a common pest primarily in central and northern Japan. [4] [5] [9] [11]
The species was found in New York City in 2013 by Evangelista et al., [12] : 581 [13] : 40 [14] the first time the species was found in the United States. [15] It was found by an exterminator beneath plantings in High Line, a Manhattan park, and was able to survive over a cold winter. [16] 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. [15] This identification demonstrates the use of DNA barcoding for urban pest control. [12] [13]
The American cockroach is the largest species of common cockroach, and often considered a pest. In certain regions of the U.S. it is colloquially known as the waterbug, though it is not a true waterbug since it is not aquatic. It is also known as the ship cockroach, kakerlac, and Bombay canary. It is often misidentified as a palmetto bug.
The Florida woods cockroach is a large cockroach species which typically grows to a length of 30–40 mm (1.2–1.6 in). When alarmed, adults can eject an extremely foul-smelling directional spray up to 1 m, which inspired several of its other common names: Florida skunk roach, Florida stinkroach, skunk cockroach, skunk roach, stinking cockroach, and stinkroach. Two other naming variations include Florida cockroach and Florida woods roach.
The German cockroach, colloquially known as the croton bug, is a species of small cockroach, typically about 1.1 to 1.6 cm long. In color it varies from tan to almost black, and it has two dark, roughly parallel, streaks on the pronotum running anteroposteriorly from behind the head to the base of the wings. Although B. germanica has wings, it can barely fly, although it may glide when disturbed. Of the few species of cockroach that are domestic pests, it probably is the most widely troublesome example. It is very closely related to the Asian cockroach, and to the casual observer, the two appear nearly identical and may be mistaken for each other.
The Surinam cockroach or greenhouse cockroach is a species of burrowing cockroach. It is a common plant pest endemic to the Indomalayan realm that has spread to tropical and into subtropical regions around the world, and in isolated populations to temperate climates where protective habitat such as greenhouses provide shelter for individuals inadvertently shipped in the soil of plants. Its populations are almost exclusively female, and it reproduces through parthenogenesis, having evolved several clonal strains from its sexual progenitor P. indicus.
The Australian cockroach is a common species of tropical cockroach, with a length of 23–35 mm (0.91–1.38 in). It is brown overall, with the tegmina having a conspicuous lateral pale stripe or margin, and the pronotum with a sharply contrasting pale or yellow margin. It is very similar in appearance to the American cockroach and may be easily mistaken for it. It is, however, slightly smaller than the American cockroach, and has a yellow margin on the thorax and yellow streaks at its sides near the wing base.
The smokybrown cockroach is a large species of cockroach, winged, and growing to a length of 32–35 millimetres (1.3–1.4 in).
The Pennsylvania wood cockroach or Pennsylvanian cockroach is a common species of cockroach in eastern and central North America.
The brown cockroach is a species of cockroach in the family Blattidae. It is probably originally native to Africa, but today it has a circumtropical distribution, having been widely introduced. In cooler climates it can only survive indoors, and it is considered a household pest.
Cockroaches are insects belonging to the order Blattodea (Blattaria). About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known pests.
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not necessarily by cold but by dry conditions; passing through such periods could likewise be called overwintering.
Periplaneta is a genus of cockroaches containing some of the well-known pest species with cosmopolitan distributions, such as:
Corazonin is a highly conserved neuropeptide found in many insects, in particular locusts and cockroaches.
Scirtothrips dorsalis, the chilli thrips or yellow tea thrips, is an extremely successful invasive species of pest-thrips which has expanded rapidly from Asia over the last twenty years, and is gradually achieving a global distribution. It has most recently been reported in St. Vincent (2004) Florida (2005), Texas (2006), and Puerto Rico (2007). It is a pest of economic significance with a broad host range, with prominent pest reports on crops including pepper, eggplant, mango, citrus, strawberry, grapes, cotton, tea, peanuts, blueberry, and roses. Chilli thrips appear to feed preferentially on new growth, and infested plants usually develop characteristic wrinkled leaves, with distinctive brown scarring along the veins of leaves, the buds of flowers, and the calyx of fruit. Feeding damage can reduce the sale value of crops produced, and in sufficient numbers, kill plants already aggravated by environmental stress. This thrips has also been implicated in the transmission of three tospoviruses, but there is some controversy over its efficiency as a vector.
Evania appendigaster, also known as the blue-eyed ensign wasp, is a species of wasp in the family Evaniidae. Its native range is not known, but it likely originated in Asia. Today it occurs throughout the tropics and subtropics and in many temperate regions. As with the rest of its family, the blue-eyed ensign wasp is a parasitoid known for specializing on cockroach eggs.
Periplaneta japanna is a subtropical field-dwelling cockroach endemic to southern Japan. The Japanese common name means urushi cockroach, or lacquer tree cockroach.
The Turkestan cockroach, Periplaneta lateralis, also known as the rusty red cockroach, red runner cockroach or simply rusty red, red runner, or lat, is a primarily outdoor-dwelling cockroach native to an area from northern Africa to Central Asia. Adults measure around 3 cm (1.2 in) in length. Adult males are a brownish orange or red, are slender, and have long, yellowish wings which allow it to attract females and to glide. Adult females are dark brown to black, with cream-colored markings on the shield and a cream-colored stripe edging its wings; they are broader than males, and have short vestigial wings. Nymphs are brown in front, black on the rear, and are wingless.
Parcoblatta divisa, the southern wood cockroach, is a species of cockroach native to the United States.
Parcoblatta americana, the western wood cockroach, is a species of wood cockroach that occurs in Mexico and the western United States.
Potato leafhopper belongs to family Cicadellidae and genus Empoasca within order Hemiptera. In North America they are a serious agricultural pest. Every year millions of dollars are lost from reduced crop yields and on pest management. Crops that are impacted the most are potatoes, clover, beans, apples and alfalfa.
Neostylopyga is a genus of cockroaches described by Robert Walter Campbell Shelford in 1911.
