Rats pose a significant problem to society (zoonoses, severe property damage and food loss). The urban environment favours high population density, especially of the Brown rat (Rattus norvegicus). Due to high food availability and the presence of attractive habitats for rats in urban parks and garde...

Arboviruses transmitted by Aedes mosquitoes becomes a serious public health problem in numerous regions with increasing worldwide cases of dengue, zika and chikungunya infections. The absence of effective vaccines leads the prevention of these diseases to be focused on vector control activities. The...

It will be twenty years in 2022 that the notifications of active substances had began in Europe. Companies mainly from Europe and a few elsewhere have notified a bit more than 1650 actives under the 21 Product Type groups. Today there are only some 450 actives left in the system. What has happened d...

Stored product pests are not typically called urban pests, however because of urbanisation and the concentration in towns and cities of the population world-wide, silos and other types of grain warehouses and mills are also nearer to cities or are even built right into the cities. One of the greates...

Insecticide resistance in bed bugs (Cimex lectularius L. and C. hemipterus F.) is a major factor in the pest’s resurgence. Various studies have demonstrated resistance to the pyrethroids, carbamates and the organophosphates. Resistance has been suspected in Australia, with anecdotal reports of poor ...

The bed bug has had a longstanding relationship with low-income high-density housing. Proximity of dwellings, re-use of furniture, and control options limited by affordability, have all contributed to the continuation of this pest in such areas. The recent resurgence and spread of this pest may be a...

Anoxia resulting from contained atmospheres of ~ 0 .1 % oxygen (1,000 ppm) was lethal to all stadia of a variety of insect pests commonly encountered in museums and other sensitive areas. Low % 02 in a closed system was achieved and maintained by displacement with gaseous nitrogen. The effect of ano...

The results of a four year study with six termiticides including: bifenthrin, chlorpyrifos, cypermethrin, fenvalerate, permethrin, and isofenphos indicate significant differences in effectiveness among products applied to different soil types in Texas. Each of the five field test locations represent...

In the European Union and the USA allergens of arthropods comprise a rising health problem. Atopic diseases resulting from insect or mite exposure cost several hundreds of millions British pounds per European country per year. This article is devoted to major sources of inhalant arthropod allergens,...

Cockroach control in the Netherlands is carried out with the use of the synthetic pyrethroids deltamethrin, cyfiuthrin or permethrin or of the organophosphate chlorpyrifos. The German cockroach is the species most frequently found in buildings. There are some indications that resistance against inse...

Public pressures, and mandates by government agencies will require that we develop strategies that reduce exposure of humans to pesticides. These must be developed so that they manipulate populations to the extent that likelihood of infestation is reduced, or assuming that they will infest a structu...

Insecticidal space sprays are widely and effectively used for control of insects in the urban environment. They are especially useful for flying insect control, be it for disease vector or nuisance pest, but space sprays can also be very effective for rapid control of crawling pests such as cockroac...

The ability of mobile stages of oriental cockroaches to survive at -5C increased with acclimation at 10°C. Fully acclimated insects had LT5Os (time) of 1.3 - 4.1 days, depending on stage. A minimum of 8 days at - 5°C or 1 days at - 10°C was required to kill all stages; insects could survive for more...

Resistance to organochlorine, organophosphorous (OP) and carbamate insecticides in the German cockroach Blattella germanica has been documented for many years. In the past, significant bendiocarb resistance has been reported in the United Kingdom. More recently, resistance has been reported to the p...

Elevation of esterase activity is the most common form of organophosphate resistance in the Culex pipiens complex. There are several electrophoretically distinguishable forms of esterase which can be elevated. Raymond et a1 (1991) have put forward the hypothesis that the most common form of elevatio...
