- Abstract
Ditylenchus halictus n. sp. was collected as dauer juveniles from the genital region of adult males and females of the soil-dwelling sweat bee, Halictus sexcinctus (Halictidae), in Brandenburg, Germany, and cultured on the fungus, Monilinia fructicola. It is the first species of Ditylenchus to be reported in an active phoretic association with insects and is described and illustrated herein. Dissections revealed that 25% of female bees carried the dauer juveniles of D. halictus n. sp. internally in the Dufour's gland and/or seminal receptacle and/or genital region (range 1-193 dauer juveniles per bee), and 38% of males were infested in the genital capsule, copulation apparatus, and/or distal testes with 1-64 dauer juveniles. Morphologically, D. halictus n. sp. has six lines in the lateral field and appears closest to D. myceliophagus but can be differentiated based upon a combination of morphological characters, the mode of reproduction and molecular sequence data. Molecular analysis of the near full length SSU rDNA, D2/D3 expansion segments of the large subunit (LSU) rDNA, and internal transcribed spacers (ITS-1 and 2) and 5.8S rDNA support that this nematode species is unique.
