Evaluation of Duopath Legionella kit for the rapid identification of Legionella strains isolated from water samples.

Duopath Legionella (Merck KGaA, Darmstadt, Germany) is a rapid and simple immunochromatographic assay kit for the identification of Legionella species. We evaluated the precision of the kit in identifying 100 strains of Legionella and 35 strains of non-Legionella bacteria isolated from cooling tower and bath water samples. Consequently, of all the Legionella strains tested, 99 strains were judged to be Legionella, and only one strain (Legionella busanensis) was judged to be non-Legionella.

Host-recognizing kairomones for parasitic wasp, Anisopteromalus calandrae, from larvae of azuki bean weevil, Callosobruchus chinensis.

Host-recognizing kairomones for the stinging behavior of the parasitic wasp, Anisopteromalus calandrae, were identified on host azuki bean weevil larvae, Callosobruchus chinensis (L.). The kairomones were extracted with acetone from Chinese green beans, from which emerged wasps and host weevils had been removed.
