A host-recognizing kairomone responsible for the stinging behavior of the parasitic wasp, Dinarmus basalis, was studied. Fresh azuki beans coated with an acetone extract of the azuki beans, from which both emerged wasps and their host weevils were removed, elicited stinging behavior from female wasps. The kairomone is a mixture of saturated hydrocarbons and diacylglycerols, both of which are required for activity. The kairomone is composed of normal and methyl-branched hydrocarbons with carbon numbers ranging from 25 to 35, most of which are known as the hydrocarbon constituents of an oviposition-marking pheromone of the host azuki bean weevils, Callosobruchus chinensis. This indicates that D. basalis utilizes the oviposition-marking pheromone of its host weevils as a host-recognizing kairomone.
Certain dimers as crystallization depressants

Page/Page column 7; 8, (2017/05/21)
This application relates to certain dimers as crystallization depressants for biodiesel fuels, and methods for making the same. Such dimers, due to their particular structure and conformation, disrupt the regular packing of linear saturated fatty acid methyl esters, thereby delaying nucleation and mitigating crystal growth. In some embodiments, the dimer includes (E)-1-(1-(oleoyloxy)-3-(stearoyloxy)propan-2-yl) 18-(1-(oleoyloxy)-3-(stearoyloxy)propan-2-yl)octadec-9-enedioate.

Paragraph 0037; 0045, (2015/11/27)
This application relates to triacylglycerol oligomers derived from the metathesis of natural oils. These oligomers are structure controlled dimers and quatrimers, and the effect of saturation, molecular size, and positional isomerization are also described herein.
