Bactrocera invadens Drew, Tsuruta & White, Bactrocera papayae Drew & Hancock, and Bactrocera philippinensis Drew & Hancock, key pest species within the Bactrocera dorsalis species complex, have been recently synonymized under the name Bactrocera dorsalis (Hendel). The closely related Bactrocera carambolae Drew & Hancock remains as a discrete taxonomic entity. Although the synonymizations have been accepted by most researchers, debate about the species limits remains. Because of the economic importance of this group of taxa, any new information available to support or deny the synonymizations is valuable. We investigated the chemical epicuticle composition of males and females of B. dorsalis, B. invadens, B. papayae, B. philippinensis, and B. carambolae by means of one- and two-dimensional gas chromatography-mass spectrometry, followed by multiple factor analyses and principal component analysis. Clear segregation of complex cuticule profiles of both B. carambolae sexes from B. dorsalis (Hendel) was observed. In addition to cuticular hydrocarbons, abundant complex mixtures of sex-specific oxygenated lipids (three fatty acids and 22 fatty acid esters) with so far unknown function were identified in epicuticle extracts from females of all species. The data obtained supports both taxonomic synonymization of B. invadens, B. papayae, and B. philippinensis with B. dorsalis, as well as the exclusion of B. carambolae from B. dorsalis.

Dermatitis contacta iritativa je pojem zahrnující zánětlivé projevy, vznikající působením toxické noxy na kůži. Během života potká každého. Při akutním průběhu se často dá zvládnout volně dostupnými prostředky, kterých je na trhu nepřeberné množství. Zejména při chronickém průběhu může docházet k senzibilizaci na mnohé látky a původně iritační dermatitida se pak mění v alergickou. Onemocnění může být komplikované bakteriální či virovou infekcí. Pak je už vhodné, aby péči vedl dermatolog.

Irritant contact dermatitis is a term referring to inflammatory reactions occurring due to the action of toxic agents on the skin. It is encountered by everyone in their lifetime. In the acute course, it can often be managed with over-the-counter products, of which there is a vast variety available in the market. In the chronic course in particular, sensitization to many substances can occur, and an originally irritant dermatitis changes into an allergic one. The disease can be complicated by bacterial or viral infection. In such a case it should be taken care of by a dermatologist.
