We investigated the seasonal abundance and flight activity of adult Limnophyes natalensis within a food industry. A total of 43,163 insects were automatically counted with a special light trap during the study period. The automatically counted numbers reflected the abundance of L. natalensis, becaus...

Pesticides are applied in residences, schools, hospitals and other edifications to control urban pests as cockroaches, ants, fleas, flies and termites. The use of these products in indoor environment can result in exposure of children and pets to particles in the air or adhered to the floor, carpets...

Globalization is a major causal agent for the introduction of exotic species into new territories. In this regard, it is well known that air traffic is an ideal route for the arrival of mosquitoes to new countries and even new continents. In order to evaluate the possible arrival of allochthonous ve...

It is the challenge of every thermal treatment to achieve the lethal temperatures in inaccessible harborages. With thermal treatments hot air is the heat transfer medium. This medium has a low heat capacity and the heat transmission rate from hot air on a solid body is relatively poor, especially if...

The poultry red mite, Dermanyssus gallinae, is the most important ectoparasite in European egg production. The mites hide in cracks and crevices in the near vicinity of the resting places of the birds, coming out to feed mainly during the night. Large mite populations may cause anaemia or even death...

When the fathers of public health were establishing the environmental health industry in the 19th century, there were five main problems facing them: poor housing conditions; inadequate pest control; a lack of proper drainage; polluted air quality; and an unwholesome supply of water. Today we have p...

Mass emergences of adult caddisflies often lead to severe nuisance conditions. The objective of this study is to clarify the abundance and seasonal trend of adult caddisflies in the middle reaches of the Shinano River. All of the adult caddisflies attracted to the illuminated showcase of a vending m...

The species composition and abundance of chironomid midges attracted to the illuminated showcase of a vending machine, set on the riverside in the middle reaches of the Shinano River (Ueda City, Nagano Prefecture, Japan), were investigated. A total of 4,439 midges (1,719 males and 2,720 females) wer...

In recent years, different essential oils, distilled from various plant species, have been used to replace chemical pesticides. 1.8-cineole (eucalyptol) has been considered as insecticide; such active ingredient is present in a number of vegetal species and it reaches the greatest concentration in t...

The Formosan subterranean termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), is the most economically important structural pest in the New Orleans metro area, Louisiana, U.S.A.. In 1998, two significant projects were initiated to determine the effectiveness of area-wide subterranea...

Carpenter ants are major structural pests in the United States, Canada, and Scandinavian countries. With the advent of non-repellent chemicals and more attractive baits, shifts have occurred in management strategies that include either perimeter sprays or baiting as the sole method for control. Four...

In the area of Lake Suwa in central Japan, massive swarms of chironomid midges have repeatedly caused problems for local residents. Until now, light has been used as the customary countermeasure against chironomids wherever they occur, e.g., around natural lakes. In recent years, large numbers of sw...

A modified Ebeling choice box was designed to evaluate the repellency of moving ambient air to American, Periplaneta americana (L.), German, Blattella germanica (L.), and smokybrown, Periplaneta fuliginosa (Serville), cockroaches using air velocities of 0 - 4.75 m/s. The modified choice box tested t...

The main sensitiser and trigger for asthma is house dust mite (HDM) allergen. Removing HDM allergens in homes has been shown to be effective in reducing symptoms in asthmatic patients. Regular vacuum cleaning is important to decrease allergen reservoirs in homes. However, vacuum cleaning with an ine...

The control of bedbugs (Cimex lectularius) as well as pigeon ticks (Argas reflexus) in human dwellings is usually carried out by a treatment with residual insecticides/acaricides combined with special flushingout- preparations. As the hiding and breeding places of bed bugs and pigeon ticks can be sp...

The past few years have seen an unprecedented interest in indoor air quality, driven in part by unexplained increases in asthma throughout the world. According to the American Academy of Allergy, Asthma, and Immunology, allergic rhinitis affects more than 40 million people yearly in the US, resultin...

House flies Musca domestica (L.) are a nuisance to humans and animals and are potential vectors of pathogens. One of the methods to control flies is using attractive odours to lure them to a trap (Cossé and Baker, 1996). However, existing commercially available baits showed variable results (Browne,...

The present investigation demonstrates the effect of a single treatment with a chitin synthesis inhibitor (lufenuron) on small, medium and large nymphs as well as adults of the German cockroach, Blattella germanica (L.).
