“…In the case of astigmatid mites, the female sex pheromones are distributed in both sexes in different amounts, even during the nymphal stages 26 . The differences in the content ratios of female sex pheromones between males and females function to aid males in recognising conspecific females.…”

Although the nymphs of Corythucha marmorata form clusters on the undersides of host plant leaves, as frequently observed for Hemiptera, the adults are scattered in the vicinity of the nymph population. By investigating the biological activities of volatile secretions from the adult, we found that the secretions activated male mounting behaviour. A chemical analysis revealed that borneol was a common component of the secretions from both sexes. The absolute configuration of the natural product was the (+)-enantiomer of borneol and the optical isomer was undetectable. Although (+)-borneol showed significant sex pheromone activity against males, the antipode (−)-borneol also induced sex pheromone activity, albeit only slightly. Males may not have a strict identification mechanism based on stereochemistry. To verify the origin of this sex pheromone, we analysed the components of the essential oil of the leaves of Solidago canadensis L. (Compositae: Asteraceae), a host plant; bornyl acetate was detected to be a major component. The plant-produced bornyl acetate had different stereochemistry from the sex pheromone. The results suggested that the adults do not utilise the secondary metabolites of plants but biosynthesise this sex pheromone themselves. This is the first report on sex pheromone identification in Tingidae.

“…was raised in a culture dish (90 mm in diameter Â 20 mm in height) by feeding dry yeast in a humid condition at around [20][21][22][23][24][25] C. The species was collected from organic soil in Ishigaki Island, and its ITS portion was composed of a 324 base pair (measured as reported 23) ). The culture dish was kept in a zip-lock plastic bag (240 Â 170 Â 0:04 mm) to maintain moisture and to prevent any escape or contamination with other mites.…”

“…The female sex pheromone is distributed between both sexes in the genus Sancassania (¼ Caloglyphus); however, the amount is biased toward females, being 1.4-8.4 times more than that in the male secretion. 20) Although the pheromone has not been studied in the genus Tyreophagus, the pheromone may also be localized in Tyreophagus females. The presence of 2 is one of the characteristics of the present species.…”

Polyalkyl furans are widespread in nature,o ften performing important biological roles.D espite ap lethora of methods for the synthesis of tetrasubstituted furans,t he construction of tetraalkylf urans remains non-trivial. The prevalence of alkylgroups in bioactive furan natural products, combined with the desirable bioactivities of tetraalkylf urans, calls for ageneral synthetic protocol for polyalkylfurans.This paper describes aM ichael-Heck approach, using sequential phosphine-palladium catalysis,f or the preparation of various polyalkylf urans from readily available precursors.T he versatility of this method is illustrated by the total syntheses of nine distinct polyalkylated furan natural products belonging to different classes,n amely the furanoterpenes rosefuran, sesquirosefuran, and mikanifuran;the marine natural products plakorsins A, B, and Dand plakorsin Dmethyl ester;and the furan fatty acids 3D5 and hydromumiamicin.
