Pheromones female tiger moth

Female tiger moths signify their presence to male moths by giving off a sex attractant (pheromone) The sex attractant has been isolated and found to be a 2 methyl branched alkane having a molecular weight of 254 What is this material... 

Chemical substances used for communication in nature are called pheromones. The pheromone used by the female tiger moth to attract the male is the 18-carbon-atom alkane 2-methylheptadecane. Write its structural... 

Z,9S,10 )-9,10-Epoxyhenicos-6-ene (13) is the female sex pheromone of moths such as ruby tiger moth (Phragmatobiafuliginosa), fruit-piercing moth (Oraesia excavata), and painted apple moth (Teia anartoides). Scheme 23 summarizes Shi s synthesis of 13 based on Sharpless asymmetric dihydroxylation (AD) [36]. Mori synthesized 13 employing lipase to prepare A (Scheme 24) [37]. Alkylation of the acetylide anion C was possible neither with tosylate nor with iodide, but triflate B could alkylate C to give D.
