An increment in human tick bite cases has been noticed in Eastern Spain in the last years. Three tick species has been detached from patients assisted at Vall d’Alba Heath Center during 2018 and 2019: Dermacentor marginatus, Hyalomma lusitanicum and Rhipicephalus sanguineus. H. lusitanicum, with 204...

The house centipede (Scutigera coleoptrata) is a thermophilic species mainly distributed in the Mediterranean region. This nocturnal predator kills its pray with toxic bites. As early as shortly after the last Ice Age it has settled in the “Kaiserstuhl”, one of the warmest regions in Germany. Procee...

The landscape of public health pest control is changing. Budgets are being cut across the country, with most local authorities (LAs) still being the main source of dealing with public health pest problems as they did before, but with significant reductions in resourcing. Through analysing the UK pes...

Mosquito Aedes aegypti is the most efficient vector in the transmission of dengue, chikungunya and zika in Colombia. Villavicencio, located in the central part of the country, is one of the cities that report more cases of these pathologies. Despite the strategies of communitarian education to contr...

The construction of a hydroelectric power station on Zeya River near the town of Zeya (Amur Region, Russian Far East) in the early 1970s spurred the development of a new urban settlement in the town for construction workers. Natural conditions of this area supported the persistence of populations of...

Dermatitis linearis is skin irritation resulting from contact with the hemolymph of rove beetles from the genus Paederus. Paederus neither bite nor sting, but accidental crushing on human skin causing the release of the toxin paederin. Massive outbreaks are frequently reported in tropical regions of...

The occurrence of Ixodes and Dermacentor ticks is not limited to natural biotopes. These arthropods inhabit recreational parks and small forests situated in the city and in the suburban zone of Warsaw as well. In studies carried out in Warsaw recently the level of infected by Borrelia burgdorferi s....

There are several regions in Poland where mosquitoes emerge in huge numbers almost every year. Some of them are areas of protected nature - mainly wetlands, where the insects cannot be controlled in mass actions. Many inhabitants or tourists visiting these regions try to cope with the problem on the...

In Brazil there are three types of spiders of medical importance, Phoneutria sp. (Araneae: Ctenidae), Loxosceles sp. (Araneae: Sicariidae) and Latrodectus sp. (Araneae: Theridiidae). The accidents are characterized as follows: accidents by Phoneutria sp. - represent a form of araneism most commonly ...

This present study focused on the Municipal Program of Culex Control at the Pinheiros River and the new methods used for surveillance and control of this mosquito. This river has 54 km of banks and its polluted and stagnant water allows great proliferation of Culex quinquefasciatus. This mosquito is...

Spiders are an important part of ecosystems due to their feeding habits which involve predation, especially of insects. This group of arthropods currently includes over 40 thousand described species present on all continents except for Antarctica. They forage in diverse ecotopes and some are resista...

Outbreaks of mysterious skin lesions on multiple personnel at five military installations were initially blamed on spiders. Requests were made for pest inspection and control to remedy the situation. Pesticides were applied at four of the installations even though no medically important arthropods w...

The bed bug, Cimex lectularius L., has made a rapid and unexpected comeback in the United States. In an online survey of 509 U.S. pest control firms, 91% encountered bed bugs in the past two years, whereas only 37% recalled seeing them five years ago. Perpetual movement of people, zero tolerance for...

Ants can bite, sting and squirt formic acid. Usually the effects of the stings are mild but ants, like wasps, are capable of multiple stinging and this can induce anaphylactic shock. A few ants (such as Formica rufibarbis) are secondary hosts of Dicrocellium dentriticum in north and northwest of Ira...

Twenty one commercial insect repellent products, including 12 natural, 6 deet-based, and 3 other synthetic organic, were evaluated as larvicides and as oviposition deterrents of Aedes albopictus. Ten of the 12 natural products at 0.1% concentration provided 57-100% mortality of laboratory-reared 4th...

Unlike insects foraging above ground where individuals can explore over an area and then lay a recruitment trail for others to follow, subterranean termites search for food by constructing underground tunnels. Studies have showed that termite tunnel orientations are affected by physical irregulariti...

Since first identified in the 1980’s, Lyme Disease has become the most widely diagnosed vector-borne disease in the United States. Lyme Disease occurs from the infection of human and animal hosts by the bacterium Borrelia burgdorferi. Infection of hosts results from the bite and completion of a succ...

Tick-borne relapsing fever (RF) is considered to be caused by the spirochaete Borrelia persica, transmitted to humans by Ornithodorus tholozani, and is a notifiable disease in Israel. Between 1980 and 2002, 184 cases were reported, i.e. an average of eight cases per year (range 0-16). Among them, ab...

Structure-infesting ants are an important group of insect pests in many parts of the world, particularly in residential premises, food outlets, and factories. In Malaysia, it is gradually becoming a major problem especially in urban settings (Lee et al., 1999; Lee and Robinson, 2001). Currently, ant...

In the Czech Republic there are large areas in the Labe and Morava – Dyje Lowlands where mosquitoes are an almost unberable nuisance following occasional summer floods (e.g. in 1997 and 1998), Aedes vexans and Ae. stictius being the main pest species. The capital of the Czech Republic, Prague, lies ...

Control of cockroach populations in urban environments is now very often performed with insecticides presented in food bait formulations. To be efficient, food baits must attract pests so that contact is made with the active substance and/or that it is ingested. Food baits may be less efficient for ...

Mosquitoes required for testing chemical or biological products have been reared successfully using anaesthetised guinea pigs as a source of blood. In an attempt to eliminate the need for keeping and using live mammals to provide the blood meal, alternative methods have been investigated. Finally th...

Skin lesions resulting from arthropod exposure may arise via various pathologic pathways. There may be direct damage to human skin from mouthparts, fangs, stingers, etc., or indirect damage such as immune reactions to arthropod saliva or venom injected upon biting. Hypersensitivity may develop again...

The phenomenon of autogeny has been well known in the Culex pipiens complex which consists of several physiological forms. Females of the autogenous form of Cx. pipiens are able to produce the first egg batch without a previous blood meal, whereas anautogenous females need a blood-meal for egg produ...

CDC traps are employed as an efficient tool in monitoring mosquito population changes, evaluation of climatic and human made changes on species abundance and composition as well as for estimation of success of control programs. Despite the great advantage in labor saving and sampling the species whi...

Among argasid ticks, Argas reflexus is one of the main parasites entering and living in houses in many Israeli towns. Its hosts are birds, mainly doves, closely linked with human dwellings. A. latus, a member of the A. reflexus group known only from Turkmenistan, was found in houses in several areas...
