out that the DL compounds 5, 8 were prepared from DL-aminobutyric acids. By analogy with the compounds 2 — 2 D and 3 3 D we expect that the biologically active components of the racemates were only their L-forms. All the compounds listed in Table I were subjected to additional topical or injection bioassays on a Pentatomid bug Graphosoma and on pupae of Tenebrio. No JH activity was recorded her...

The genus Ambrosiella accommodates species of Ceratocystidaceae (Microascales) that are obligate, mutualistic symbionts of ambrosia beetles, but the genus appears to be polyphyletic and more diverse than previously recognized. In addition to Ambrosiella xylebori, Ambrosiella hartigii, Ambrosiella beaveri, and Ambrosiella roeperi, three new species of Ambrosiella are described from the ambrosia ...

Trissolcus egg parasitoids, when perceiving the chemical footprints left on a substrate by pentatomid host bugs, adopt a motivated searching behaviour characterized by longer searching time on patches were signals are present. Once in contact with host chemical footprints, Trissolcus wasps search longer on traces left by associated hosts rather than non-associated species, and, in the former ca...
