The novel mesoionic insecticide triflumezopyrim was highly effective in controlling both imidacloprid-susceptible and resistant planthopper populations in Malaysia. However, the toxicity of triflumezopyrim to planthopper populations and their natural enemies has been under-investigated in China. In this study, the median lethal concentrations (LC50) of triflumezopyrim were determined in eight field populations of Nilaparvata lugens and one population of Sogatella furcifera from China under laboratory conditions...

Paederus fuscipes, a health pest, causes dermatitis linearis in humans. Wintergreen oil exhibits optimal insecticidal activity against P. fuscipes. However, the insecticidal mechanism remains unclear not only in P. fuscipes but also in other pests. In this study, we explored the insecticidal mechanism of wintergreen oil in terms of its effect on the activity of acetylcholinesterase (AChE) enzyme and detoxifying enzymes (carboxylesterase, glutathione-S-transferase, and mixed function oxidase); such effect was studied by fumigation both in vivo and in vitro in P...

Vorderman (1901) was the first to record blisters caused by beetles in medical literature. Blister beetle dermatitis is a cutaneous condition caused by the toxins released by blister beetles. The vesicant chemical in the body fluids of these insects causes an acute irritant contact dermatitis characterized by erythematovesicular lesions associated with burning sensation on exposed parts of the body. The aim of this study was to investigate the morphological patterns of blister beetle dermatitis. We conducted a 1-year (January-December 2014) prospective study of the clinical presentation of Paederus dermatitis noticed in urban and semiurban areas close to paddy fields in the Cauvery Basin, Mysuru, Karnataka...

Paederus dermatitis is an irritant dermatitis caused by pederin, a toxin produced by the rove beetle (Paederus). The disease occurs worldwide, but it is often not recognized as a history of contact with the insect is frequently absent. It is commonly seen in the rainy season. Crushing the insect releases pederin, resulting in the characteristic linear lesions with a burning sensation that heal with hyperpigmentation. Treatment comprises immediate washing of the area to eliminate the toxin and topical application of a topical steroid-antibiotic combination...

Paederus fuscipes, a vector of Paederus dermatitis in most tropical and subtropical countries of the world have a high prevalence in human dwellings due to their positively phototaxic behaviour which has caused a tremendous impact on human health. In this paper, P. fuscipes dispersal flights were studied for two seasons of the rice cultivation phases in residential premises built close to rice field areas (≈32-60 m and 164 m) in mainland Penang, Malaysia. We examined the effects of different light illuminance, building floor level and their association with rice stages as a focal cause of P...

BACKGROUND: Linear dermatitis is endemic in Iran where most cases occur in the Caspian Sea coast and Fars province. The disease is caused by beetles of the genus Paederus which are active from early spring to beginning of autumn although its incidence rises from May to August. The classic taxonomy of Paederus spp. is based on the male genitalia that is very complex and needs expertise. In this study, we report a DNA-based method to discriminate Paederus fuscipes and Paederus littoralis (=syn: P...

Paederus fuscipes Curtis is a nocturnal insect. The attractiveness of artificial light sources from residential premises eventually causes the risk of severe dermatitis effect, once Paederus is in contact with human skin. The objective of this study is to investigate whether the light and height factors of residential buildings and its' association to rice cultivation phases are primary reasons for P. fuscipes's mass dispersal into human residential areas. The study site was located in residential premises that were built adjacent to rice field areas (≈ 32-60 m and 164 m) north of the rice field located in Teluk Air Tawar, mainland of Pulau Pinang...

T1C-19 is newly developed transgenic rice active against lepidopteran pests, and expresses a synthesized cry1C gene driven by the maize ubiquitin promoter. The brown planthopper, Nilaparvata lugens, is a major non-target pest of rice, and the rove beetle (Paederus fuscipes) is a generalist predator of N. lugens nymphs. As P. fuscipes may be exposed to the Cry1C protein through preying on N. lugens, it is essential to assess the potential effects of transgenic cry1C rice on this predator. In this study, two experiments (a direct feeding experiment and a tritrophic experiment) were conducted to evaluate the ecological risk of cry1C rice to P...

This irritant blister dermatitis is caused by the genus Paederus whose geographical distribution is worldwide, with a higher incidence in tropical areas. It is induced by direct skin contact with pederin, a blistering and caustic substance found in the abdomen (coelome) of Paederus insects (insect order Coleoptera: family Staphylinidae). The diagnosis is based on the presence of typical clinical features combined with compatible epidemiological features. Our goal is to describe the epidemiological and clinical features of this irritant contact dermatitis in Cameroon through a retrospective study conducted at the end of the rainy season at the Oku Hospital in Northwest Cameroon and to also include cases reported at the medical center of the French Embassy in Yaounde during this same timeframe...
