“…According to Briscoe and Chittka 34 , the insect vision perceives three specific colors of the ultraviolet, blue or green, while red or infrared lights emitted by the tungsten incandescent light bulb are invisible to certain insect species. Paederus fuscipes are mostly found attracted to fluorescent lightings instead of tungsten filament incandescent light bulbs 35 . During our experiment on the dispersal of beetles towards human dwellings, fluorescent lamps were predominantly used for lighting in all landed houses and high-rise apartment building.…”

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. fuscipes dispersion from the rice fields towards human dwellings. The present study showed a significant interaction between different light illuminances and rice cultivation phases in attracting P. fuscipes to disperse and invade human dwellings. The highest number of P. fuscipes was captured near the bright light. P. fuscipes flights increased in line with each floor level, and the highest captures took place at higher building floor levels (levels 2 and 3) compared to lower building floor levels (ground floor and level 1) of a three storey apartment in both rice seasons. This finding not only conveys a better understanding on P. fuscipes dispersal pattern, but also draws public attention on the occurrence of dermatitis linearis caused by the Paederus beetles.

IntroductionContact dermatitis due to Paederus is a particular form of accident by animal contact. It is characterized by the sudden onset of erythematous and vesicular lesions with burning sensation on exposed areas of the body. The aim of this study was to describe the epidemiological and clinical findings of an outbreak of Paederus dermatitis in Panama.MethodsClinical and epidemiological findings of an outbreak of contact dermatitis caused by Paederus sp. in the province of Darien in eastern Panama is reported. After reviewing the clinical records, a clinical-epidemiological questionnaire was developed and used in 20 communities where reported cases were found. We captured and collected the specimens for species characterization for three consecutive days using three different methods of capture.ResultsDuring May-July, 2014, 68 cases of Paederus irritant contact dermatitis occurred in 20 communities of the Darien. Fifty-three percent were females. The age group of zero to five years had the highest number of cases, 15 (22%). The most common clinical presentation was the classical linear dermatitis (58%); 42% of the subjects had mirror image lesions, multiple vesicular-pustular lesions, and crust lesions. Symptoms were most commonly reported as a burning sensation (65%), followed by pruritus in 60%, pain (25%), and fever (nine percent). A total of 81 specimens of Paederus were collected, 68% in peridomiciliary areas.ConclusionsThis Paederus sp. dermatitis report represents one of the largest outbreak described in Latin America and the diagnosis could be confused with others skin diseases like pyodermitis or other contact dermatitis.

“…Keratoconjunctivitis or periorbital dermatitis due to Paederus beetle is popularly called as “Nairobi eye.”[ 1 ] The ocular involvement is usually unilateral in nature. [ 4 ] The eyes being an exposed part during sleep, and presence of rugosities, make periorbital area prone to deposition of pederin. [ 3 ] The periocular lesion can be either due to the direct contact of the toxin or by accidental transfer through fingers from elsewhere on the skin.…”

“…[ 1 ] The toxin, being a weak base, cannot penetrate the cornea and conjunctiva and hence the damage is limited. [ 4 ] Iritis and keratitis may occur secondary to mechanical trauma when a beetle hits the eye with force. The other complications include post-inflammatory hyper pigmentation and temporary blindness.…”

“…The differential diagnosis to be considered are herpes simplex, herpes zoster ophthalmicus, impetigo, acute allergic or irritant contact dermatitis, millipede dermatitis, phytophotodermatitis, preseptal cellulitis, and dermatitis artefacta. [ 3 4 ] Immediate washing of the contact area with soap and water, wet compresses and topical steroids forms the mainstay of treatment. [ 1 ]…”
