  摘要：

  Four EAG-active components (A-D) were found in the solvent extract of virgin females of the clear-winged tussock moth, Perina nuda, The most abundant component (B, ca. 250 ng/female) was identified as (3Z,6S,7R,9Z)-6,7-epoxyhenicosa-3,9-diene by GC-MS analyses of the extract, chemical derivatization, and comparative chiral HPLC. Minor components also elucidated were (3Z,9Z)-cis-6,7-epoxyicosa-3,9-diene, (A); (3R,4S,6S,7R,9Z)-3,4-6,7-diepoxyhenicos-9-ene, (C): and its 3S,4R,6S,7R isomer, (D): with amounts of 0.4, 5, and 8 ng/female, respectively. Component B showed weak attractiveness to mate moths in the field. The attractiveness was significantly enhanced by addition of component(s) C and/or D. No males were captured with either the antipode of component B or its mixtures with the minor components. In this field test, noctuid Hypocala rostrata males were also attracted with the synthetic P. nuda pheromone.

  The Synthesis of Long Chain Dialkylalkynes, Dialkyldiynes and Their Hydrogenation to Monoenes and Dienes

  摘要：

  Long methylenic chain dialkylalkynes have been synthesised in high yield by an improved procedure. The methodology has been extended to nonconjugated diynes. Catalytic hydrogenation with a poisoned palladium catalyst affords cis-monoenes and cis,cis-dienes respectively. An improved synthesis of cis-9-tricosene is described.
