  • THE ECOLOGY and MANAGEMENT of the ORIENTAL COCKROACH Blatta Orientalis
    THE ECOLOGY AND MANAGEMENT OF THE ORIENTAL COCKROACH Blatta orientalis l. (ORTHOPTERA: BLATTIDAE) IN THE URBAN ENVIRONMENT by Ellen Mary Thoms Dissertation submitted, to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of DOCTOR OF PH I LOSO PHY in Entomology APPROVED: W.H Robinson, Chairman J.B. Ballard R.M. Andrews J. L. Eaton D. E. Mullins May, 1986 Blacksburg, Virginia THE ECOLOGY AND MANAGEMENT OF THE ORIENTAL COCKROACH Blatta orientalis L. (ORTHOPTERA: BLATTIDAE) IN THE URBAN ENVIRONMENT by Ellen Mary Thoms Committee Chairman: William H Robinson Entomology (ABSTRACT) The oriental cockroach, Blatta orientalis L., was found to be an important seasonal household pest. Of 151 residents interviewed in two Roanoke apartment complexes in Virginia, 90% had seen oriental cockroaches, 60% considered one oriental cockroach indoors to be a problem, and 77% had taken steps to control these cockroaches. Monitoring oriental cockroach populations indicated when and where treatment would be necessary to reduce cockroach infestations. The adult cockroach population peaked in late June and July, and declined through August and September while the number of nymphs increased. Eighty percent of all cockroaches trapped at Roanoke apartment buildings were caught at porches, the primary cockroach harborage sites. In a mark-recapture study at four apartment buildings, 50% of the resighted oriental cockroaches remained at one porch, 36% moved alc:>ng one side of a building, 13% moved between the front and back of a building, and 2% moved between two buildings. Only 1-5% of the oriental cockroaches marked outdoors were ever captured indoors.

    EENY159 Oriental Cockroach, Blatta orientalis Linnaeus (Insecta: Blattodea: Blattidae)1 Kim McCanless2 Introduction The origin of the oriental cockroach, Blatta orientalis Linnaeus, is uncertain, but it is thought to be from Africa or south Russia. It is a major household pest in parts of the northwest, mid-west, and southern United States. It is also sometimes referred to as the “black beetle” or a “water bug” because of its dark black appearance and tendency to harbor in damp locations.

  • Characters for Identifying Common Families of Blattodea1 (Not Including Termites)
    Characters for Identifying Common Families of Blattodea1 (not including termites) Cryptocercidae and Blaberidae have NO spines on the posteroventral margins of the middle and hind femora. These roaches do not occur in Minnesota, but are none-the- less interesting. Cryptocercidae - Brown-hooded cockroaches. Wings completely absent in adults and nymphs; sides of body nearly parallel-giving a more elongate appearance; 7th abdominal tergum and 6th sternum extend over tip of abdomen (hiding the cerci); sub- social, lives in colonies in rotting logs. The common, Cryptocercus punctulatus, along with other species in the genus, is found in the mountains of the eastern US; other species occur in the Pacific Northwest and in China. They are wingless and live communally in rotting logs, especially oak, and are able to ingest wood with the aid of symbiotic flagellates. Blaberidae - Giant cockroaches and relatives. Tip of abdomen not covered by preceding abdominal sclerites; usually with wings. Usually large species (> 15 mm or much larger) or smaller and pale green. Not sub-social, solitary These are roaches of the Deep South and tropical areas, including the Surinam roach, Pycnoscelus surinamensis, the giant cockroach, Blaberus discoidalis, and the green banana roach, Panchlora nivea. 1 Characters from Bland and Jaques (1978); photographs from Univ.

As pests, many are omnivorous, feeding on and defiling our foodstuffs, books, and other possessions. What is perhaps less well known is their relation to the spreading of disease. Several species of cockroaches closely associated with man have been shown to be capable of carrying and transmitting various microorganisms (Cao, 1898; Morrell, 191 1 ; Herms and Nel- a resurgence of inter- son, 191 3 ; and others). Recently there has been est in this subject, and some workers have definitely implicated cock- roaches in outbreaks of gastroenteritis. Antonelli (1930) recovered typhoid bacilli from the feet and bodies of Blatta orientalis Linnaeus which he found in open latrines during two small outbreaks of typhoid fever. Mackerras and Mackerras (1948), studying gastroenteritis in children in a Brisbane hospital, isolated two strains of Salmonella from Periplaneta americana (Lin- naeus) and Nauphoeta cinerea (Olivier) that were caught in the hos- pital wards.

  • The Cockroach – the World’S Oldest Pest
    Cockroaches, Blattodea , are insects to which we have a particular aversion. They make a mess and often occur in large numbers in places we certainly don’t want to see them - in our kitchens and larders! The cockroach – the world’s oldest pest THE COCKROACH IS ALSO one of the oldest insects in the world. Species very similar to present-day cockroaches have been found in deposits dating back to the Carboniferous period. This means that cockroaches are an astonishing 400 million years old. There are about 4 000 species, about ten of which live close to humans. The others can be found in the natural environment, mostly in the Tropics. The largest species can be almost 12 cm long and the smallest just a few millimetres. Cockroaches are closely related to grasshoppers and crickets. They are flat with a large neck shield, have large spiny legs and two long, thin antennae protruding from their inward-pointing head. The back of the fully-fledged adult is covered by a pair of parchment-like wings, although cockroaches don’t normally fly long distances. Indoors, they normally move by running, and they can run very fast. The species that live and breed indoors in Sweden are the German cockroach, Blattella germanica , and the brown-banded cockroach, Supella longipalpa . COCKROACHES ARE OMNIVORES. The species that occur in the Tropics live on the ground, where they degrade leaves and dead animals. In our indoor environment, they eat anything they can get at. They are averse to light and are therefore active at night. They give off a nasty- smelling secretion from glands in the abdomen and their droppings are also malodorous.

  • Blattodea (PDF)
    Blattodea BLATTODEA Cockroaches / Waterbugs The name Blattodea is derived from "blatta", the Greek word for cockroach. Classification Life History & Ecology Distribution Physical Features Economic Importance Major Families Fact File Hot Links Life History & Ecology: The cockroaches, often known as "waterbugs", are scavengers or omnivores. They are most abundant in tropical or subtropical climates, but they also inhabit temperate and boreal regions. Some species are commonly found in close association with human dwellings where they are considered pests. Cockroaches have an oval, somewhat flattened body that is well-adapted for running and squeezing into narrow openings. Rather than flying to escape danger, roaches usually scurry into cracks or crevices. Much of the head and thorax is covered and protected dorsally by a large plate of exoskeleton (the pronotum). When cockroaches lay eggs, the female's reproductive system secretes a special capsule around her eggs. This structure, known as an öotheca, may be dropped on the ground, glued to a substrate, or retained within the female's body. Production of an öotheca is a special adaptation found only in cockroaches and http://www.cals.ncsu.edu/course/ent425/compendium/roach.html (1 of 5) [10/24/2007 12:06:22 PM] Blattodea praying mantids.

  • MF2765 Cockroaches: Household Pests
    Household Pests Cockroaches Cockroaches are one of the most common household insect pests. A major concern with cockroaches is that they are repulsive and objectionable to people simply by their presence. They are also capable of transmitting bacterial pathogens (Salmonellla spp., Shigella spp. Staphylococcus spp., Streptococcus spp.) that cause food poisoning, diarrhea, or typhoid. Recently, cockroaches have been recognized as being an important source of indoor allergens found in their body, saliva and fecal matter. Cockroaches can also damage household items, by eating glue in wallpaper, books, and furniture. Habitat The place where cockroaches live and eat is called their habitat. Cockroaches may become pests in homes after being introduced in cartons, grocery bags and containers. In apartment complexes, cockroaches move via common plumbing fixtures connecting individual units. Nymph Cockroaches prefer warm, undisturbed areas with high humidity and a nearby source of food. In general, cockroaches are active at night. By day, they hide in dark areas such as under Adult refrigerators and stoves, in kitchen cabinets, and in cracks and crevices in walls. Their oval, flattened body shape allows them to enter cracks and crevices easily. They are extremely hardy and can survive long periods without food or water. Egg case Life cycle Figure 1. Life cycle of a cockroach (Courtesy of WHO) Cockroaches undergo incomplete metamorphosis that consists of three stages: egg, nymph (immature), and adult. Quick facts about roaches Depending on the species, 12 to 40 eggs are contained in an ootheca (egg case) that protrudes from the tip of the female • Obnoxious: Roaches are among the most intolerable abdomen.

Yöntemler: 2014 yılı Nisan ve Eylül ayları arasında, Antalya şehir merkezinin 5 farklı lokalitesindeki rögar, kanalizasyon ve bodrum katlarından P. americana’nın yumurta paketleri toplanmıştır. Ergin parazitoit çıkışını belirlemek için yumurta paketleri plastik kaplara alınarak 26±2 °C sıcaklık, %60±5nem ve 12 saat aydınlık-12 saat karanlık fotoperiyot koşullarında 3 ay süreyle inkübe edilmiştir. Bulgular: Üç aylık inkübasyon süresi sonunda Konyaaltı ilçesi, Toros mahallesinden toplanan yumurta paketlerinden 6 adet yumurta parazitoiti Evania sp. (Linnaeus) (Hymenoptera: Evaniidae) çıkışı olmuştur. Diğer bölgelerden toplanan yumurta paketlerinde parazitoit çıkışı gözlenmemiştir. Parazitoit çıkışı gözlenen yumurta paketlerinin her biri sadece bir adet çıkış deliğine sahiptir. Sonuç: Doğal ortamlarda hamam böceği popülasyonları parazitoitler tarafından parazitlenmektedir. Bu nedenle biyolojik mücadele açısından önemli olan parazitoitlerin korunması, çoğaltılması ve hamam böceği mücadelesinde aktif olarak kullanılması yönünde daha çok araştırma yapılması önem arz etmektedir.

We established the presence of three species (out of five recorded in Europe): Brachygaster minutus, Prosevania fuscipes and Zeuxevania splendidula, the last based on an old literature report. We briefly discuss the patterns of their distribution and occurrence, in relation to their specific bionomy and the collecting techniques applied. KEY WORDS: Brachygaster, Prosevania, Zeuxevania, parasitoids Introduction Members of the family Evaniidae are parasitoid wasps that oviposit their eggs in the oothecae (egg-case) of cockroaches (e.g., Crosskey, 1951; Roth & Willis, 1960; Brown, 1973). Their larvae live solitarily inside an egg-case, feeding on its nutrition contents (Townes, 1949; Cameron, 1957; Deans, 2008). Together with Aulacidae and Gasteruptiidae, the family Evaniidae is classified in the superfamily Evanioidea (Deans, 2008). The three families share the common trait of a metasoma attached very high on the propodeum. In addition, members of the Evaniidae have a unique general morphology, with relatively large, nearly cubic mesosoma and comparably small, petiolate and laterally compressed metasoma.

  • Cockroach Management for the Homeowner
    Cockroach Identification and Management for the Homeowner HANDOUT Cockroaches are among the world’s most common household insect pests and they've been here for about 300 million years. Today there are about 3500 known species worldwide. Approximately 55 species can be found in the United States. Of these, only six are likely to be troublesome for Arkansans. These species include the German cockroach (Blattella germanica), the brown-banded cockroach (Supella longipalpa), the American cockroach (Periplaneta americana), the smokybrown cockroach (Periplaneta fuliginosa), the oriental cockroach (Blatta orientalis), and woods cockroaches (Parcoblatta spp.) Although cockroaches have never been incriminated as disease vectors in epidemics, their close association with people and food supplies necessitates effective cockroach management. Their habits, body structure, and mobility make cockroaches well adapted for mechanically transmitting diseases, and laboratory experiments have shown that such mechanical transmission can occur. Also, besides being particularly objectionable and repulsive, cockroaches have now been found to be an important source of household allergens. The German cockroach is the most troublesome of all cockroaches. It is light brown with a pair of parallel brown bars between the head and the front of the wings. Adults are about 5/8- inch long.
