PMID: 25987889
Front Zool. 2015 May 17;12:10. doi: 10.1186/s12983-015-0102-4. eCollection 2015.

BACKGROUND: Nymphs of many spittlebug species are known to aggregate in one spittle mass, a behavior which greatly benefits the survival of the developing nymphs. Little is known, however, about the precise mechanisms that induce and regulate aggregation. Here,...

Evidence for stereoelectronic effects in the N-C-N group of 8,10,12-triaza-1-azoniatetracyclo[8.3.1.1(8,12).0(2,7)]pentadecane 4-nitrophenolate 4-nitrophenol monosolvate from the protonation of aminal (2R,7R)-1,8,10,12-tetraazatetracyclo[8.3.1.1(8,12).0(2,7)]pentadecane: X-ray and natural bond orbital analysis.

The title molecular salt, C11H21N4(+)·C6H4NO3(-)·C6H5NO3, (II), crystallizes with two independent three-component aggregates in the asymmetric unit. In the cations, the cyclohexane rings fused to the cage azaadamantane systems both adopt a chair conformation. In the crystal structure, the aggregates...

In the title complex, [PdCl2(C12H22S3)]·0.8CH3CN, a potentially tridentate thioether ligand coordinates in a cis-bidentate manner to yield a square-planar environment for the Pd(II) cation [mean deviation of the Pd from the Cl2S2 plane = 0.0406 (7) Å]. Each square-planar...

Identification of major components of larviposition pheromone from larvae of tsetse fliesGlossina morsitans morsitans Westwood andGlossina morsitans centralis Machado.

PMID: 24226080
J Chem Ecol. 1996 Jul;22(7):1211-20. doi: 10.1007/BF02266961.

The presence of pheromones produced by larvae ofGlossina morsitans morsitans andG. m. centralis, respectively, which attract gravid females and result in aggregation of pupae, is confirmed. Behavioral experiments indicated that females preferred to larviposit over moist sand conditioned by...

In this Account, we briefly discuss the recently discovered and rapidly developing superbase-promoted self-organization reactions of several equivalents of acetylenes and ketones to afford complex compounds that represent promising synthetic building blocks common in natural products. Notably, acetylenes play...

Insect epicuticle hydrocarbons (CHC) are known to be important determinants in the susceptibility degree of insects to fungal entomopathogens. Five Beauveria bassiana (Balsamo) Vuillemin (Hypocreales; Clavicipitaceae) strains were phenotypically analyzed regarding their response to CHC nutrition and their pathogenicity...
