Insecticidal baits are one of the most popular tools for controlling cockroaches. They rely on precise label dosage guidelines to achieve control for a varied number of cockroach species. Periplaneta americana can consume high quantities of bait before being incapacitated. This has the potential for...

In April 2018, the Vector Control Department of Health Madrid received a communication from a pest control company about an Australian cockroach (Periplaneta australasiae) infestation in a building. After an initial inspection of the affected area, the presence of two foci was detected and entomolog...

The control in the field of insect large geographical distribution as Periplaneta americana species, that is a mechanical vector of several pathogens to man, may be affected by genetic variability among their populations. They can be segregating, resulting in differences in susceptibility to the con...

Periplaneta americana and Blattella germanica are pests of great importance in urban areas, mainly due to their role as vectors of pathogens and capability of causing allergies. The interspecific differences between these cockroaches can lead to different results in their control. No chemical (liqui...

The applicability of entomopathogenic fungi for Periplaneta americana’s control in urban sewage is still not well studied, even though its importance as an urban pest capable of disease dissemination being a constant. Females have an important role on dissemination of the species due to their ovipos...

Cockroaches (Blattodea) are important mechanical vectors for the transmission of many pathogens including bacteria, protozoa, fungi, and viruses, and can contaminate food, water, and affect animals and humans. These pathogens can be carried in different parts of the cockroach body (legs, mouthparts)...

Gel bait treatments are widely used for cockroach control, in part because they are considered to be safer and more effective than other methods. However, commercially available baits are considered to have a limited range over which they can attract and, as a result, fail to lure cockroaches out of...

Entomopathogens have been used in many agricultural and veterinary programs of pest control. Studies with fungi have shown great potential for control of urban pests, such as cockroaches, but there are few studies on the subject. Thus, the aim of this study was to investigate the pathogenicity of en...

Periplaneta americana is a vector of various diseases and its control is usually done with chemical pesticides. However, this insect can be controlled with the use of entomopathogenic fungal formulations. Therefore, it is necessary to identify these control agents and also characterize sprays used i...

Commo...

Health services are colonized by urban pests, being generally an integral part of urban infrastructure, especially considering the neotropical climate that is warm and wet. Therefore, pest control is widely quoted in our legislation and hospitals should be free of pests. In practice, it is observed ...

Dietary carbohydrates, lipids, and proteins constitute the nutrient reserves for the American cockroach, Periplaneta americana. Adults collected from an urban population were evaluated by their body weight and for their storage and utilization of metabolic reserves. Mean dry body weight of females c...

LT50 values for American cockroaches ranged from &...

Shape and characteristics in five domiciliary cockroach-feces Feces of domiciliary cockroaches often contaminate food or medicine packages. The presence of feces in foraging places is evidence of a cockroach infestation. The shape and other characteristics of feces differ among species. When they fe...

Field studies were conducted to compare the performance of a new formulation of Goliath® cockroach gel (0.3g/kg fipronil) to a range of other commercial cockroach gels. These were carried out in Sydney, NSW, Australia, against German cockroach, Blattella germanica (L), and in Cairns, Queensland, Aus...

The use of baits for the control of cockroaches in homes is now commonplace. To date, most bait studies have focused on the German cockroach, Blattella germanica (L). However, in many parts of the world, especially the tropics, the American cockroach,Periplaneta americana(L), is a more common pest. ...

Experimental gel and powder bait formulations containing 0.25, 0.5, and 1.0% Indoxacarb were evaluated in a series of laboratory and field studies against the German cockroach,Blattella germanica (L.). Mortality was first determined in 18 by 31 by 10 cm plastic boxes with loosely fitting covers. Twe...

Pest status of household and structural pests is based primarily on their persistence in the urban environment. Persistence of pest populations is determined by availability of reservoir habitats that harbor large and stable populations, which supply individuals to maintain small, local infestations...

Most formulates that are using now for their control have relatively low persistance and this forces to increasing the treatme...

Cockroaches could represent one of the most important hygienic problems, since they can contaminate food with bacteria, transmit diseases and cause human allergies. For this reason, urban governments and food industries devote part of their balance to cover the cost of their control. One of the firs...

Lithium perfluorooctanesulfonate (LPOS, proposed common name SulfotineTM) is an isomeric mixture containing approximately 70% of the linear isomer and 30% branched isomers. Molecular formula for LPOS is C8F17LiO3S, and acute oral LD50 is greater than 5,000 mg/kg. LPOS exhibits promising oral toxicit...

Cockroaches settling down in various sanitary trade institutions, industrial establishments as well as in residential buildings may spread potential infectious diseases and allergy or - through their disgust provoking effect - may disturb people living or working there. As a consequence, regular con...

Laboratory comparisons of pyrethroid toxicities on a range of insect pests demonstrated greater kill activity than expected for the photolabile allethrin series compounds relative to other pyrethroids. Further investigation in chamber and warehouse trials confirmed the utility of S-bioallethrin in s...

A focal point for pest management programs is often limiting the amount of insecticide to the minimum level while still maintaining the maximum benefit for population reduction. With that in mind we conducted a field study in 28 homes to evaluate the efficacy of applying insecticide to habitats iden...

Decision-making for managing household cockroach infestations is a complicated process. Proper decisions concerning cockroach pest management should be made based on the integration of 1) biotic factors, such as pest biology, ecology, and behavior; 2) abiotic environmental factors, such as temperatu...
