(Z)-5-dodecen-1-ol (Z5-12:OH), (Z)-5-dodecenyl acetate (Z5-12:Ac), and (Z)-5-tetradecenyl acetate (Z5-14:Ac) were found in the extracts of the female sex pheromone gland of the carpenterworm moth Holcocerus artemisiae Chou et Hua, a pest of Artemisia filifolia. The average amounts of Z5-12:OH, Z5-12:Ac, and Z5-14:Ac in a single sex pheromone gland of a calling moth were (7.14 +/- 0.73) ng, (54....

BACKGROUND The Chinese pine caterpillar moth, Dendrolimus tabulaeformis Tsai and Liu (Lepidoptera: Lasiocampidae) is the most important defoliator of coniferous trees in northern China. Outbreaks occur over enormous areas and often lead to the death of forests during 2-3 successive years of defoliation. The sex pheromone of D. tabulaeformis was investigated to define its chemistry and behaviora...

Fractional branes on the non-compact orbifold C3/Z5 are studied. First, the boundary state description of the fractional branes are obtained. The open-string Witten index calculated using these states reproduces the adjacency matrix of the quiver of Z5. Then, using the toric crepant resolution of the orbifold C3/Z5 and invoking the local mirror principle, B-type branes wrapped on the holomorphi...

Extracts of female sex pheromone glands of the sand Salix carpenterworm moth, Holcocerus arenicola, a serious pest of desert thicket, were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Based on comparison of retention times and mass spectra of synthetic standards, four compounds were identified as cis-7-tetradecen-1-ol (Z7-14:OH), cis-5-tetradecen-1-yl ac...

Using the renormalization group approach, the Coulomb gas and the coset techniques, the effect of slightly relevant perturbations is studied for the second parafermionic field theory with the symmetry Z5. New fixed points are found and classified. ∗ Unité Mixte de Recherche UMR 7589 While the first series of parafermionic conformal field theories [1] is well studied and applied in various domai...

A three-generation SU(5) GUT (three 10 and a single 5–5 pair) is constructed by compactification of the E8 heterotic string. The base manifold is the Z5 × Z5-quotient of the quintic, and the vector bundle is the quotient of a positive monad. The group action on the monad and its bundle-valued cohomology is discussed in detail, including topological restrictions on the existence of equivariant s...

A novel electroactive porous aromatic framework (JUC-Z4-Cl) was designed and synthesized via Yamamoto-type Ullmann cross-coupling reaction with the monomer tris(4-chlorophenyl)phosphine. By simple redox chemical reactions, stable, reductive, porous polytri(p-phenyl)phosphine (JUC-Z4) and polytri(p-phenyl)phosphine oxide (JUC-Z5) could be obtained as off-white powders. The structures of JUC-Z4 a...

A computer calculation with Magma shows that there is no extremal self-dual binary code C of length 72 that has an automorphism group containing either the dihedral group D10 of order 10, the elementary abelian group Z3 ×Z3 of order 9, or the cyclic group Z7 of order 7. Combining this with the known results in the literature one obtains that Aut(C) is either Z5 or has order dividing 24.

We recently defined cancer metastatic chemoprevention as utilizing safe and effective molecules to comprehensively prevent the spark of activation-adhesion-extravasation-proliferation metastatic cascade caused by circulating tumor cells (CTCs). The strategy focuses on preventing the most important starting point of the cascade. We identified an extract from a well-known medical plant Murraya pa...

While many Plusiinae species commonly secrete (Z)-7-dodecenyl acetate (Z7-12:OAc) as a key pheromone component, female moths of the rice looper (Plusia festucae) exceptionally utilize (Z)-5-dodecenyl acetate (Z5-12:OAc) to communicate with their partners. GC-MS analysis of methyl esters derived from fatty acids included in the pheromone gland of P. festucae showed a series of esters monounsatur...
