A cross-coupling reactions of terminal alkynes with terminal alkenes 32 supported on Merrifield-resin (Scheme 4.5) in the presence of Grubs ruthenium initiator [Cl2(PCy3)2Ru = CHPh] provided efficient access to supported 1,3-dienes 33 which were transformed into octahydrobenzazepinones 34 via MeAlCl2 catalyzed Diels-Alder reaction [27]. 

Diene alcohol (38) is the pheromone of the codling moth, tlie creature responsible for the grubs in apples, and of the various possible disconnections (a) is best as it gives most simplification and a stabilised ylid (39) which will produce the requi red trans double bond. Allylic bromide (40) and aldehyde-ester (41) are available,... 

Although not of fatty acid origin another group of scarab beetles utilizes amino acid derivatives as pheromones [119]. The large black chafer, Holotrichia parallela, uses L-isoleucine methyl ester [ 120] and the cranberry white grub, Phyllophaga anxia, uses both L-isoleucine and i.-valine methyl esters [121]. More recently L-isoleucine methyl ester, N-formyl L-isoleucine methyl ester, and N-acetyl L-isoleucine methyl ester were identified in the scarab beetle Phyllophaga elenans [ 122]. These pheromone components are obviously derived from the amino acids isoleucine and valine. 

While considering these issues it is worthwhile to have in mind the quite amazing transformations that occur both early and late in the life of certain animals. One only has to examine the life of many an insect from egg to grub to chrysalis to adult...

Cannayane et al. (2007) conducted a laboratory experiment to test the pathogenic potential of H. indica and S. glaseri on cardamom root grub, Basilepta fulvicorne. After mortality the cadaver of B. fluvicorni exhibited brick red to brown colour when infested with H. indica and also luminescent under ultraviolet, whereas, yellow and flaccid nature was due to S. glaseri infestation.

Rut give it to the clod, lo the self-indulgent, to the blase—to the average man, in a word—and he is lost. He flays, and his logic is perfect This is what 1 want. He knows not, neither can he know, the true path and the false path is the only one for him. There is cocaine at his need, and he takes it again and again. The Contrast between his grub life and his butterfly life is too bitter for his unphilosophic soul to bear he refuses to take the brimstone with the treacle,... 

The principal soil inhabiting pests of corn are the larvae of Diahrotica and white grubs. While more research needs to be done on the dosage requirements and residual effects of the chemicals used to control these important pests under tropical conditions, results to date indicate that the soil insecticides commonly used in the United States, such as chlordan, aldrin, and dieldrin, are promising. 

Other insects are of local importance including various beetles, grubs, the lesser cornstalk borer, and several vectors of virus diseases. The latter might be controlled by systemic insecticides. 

The leaf miner, Leucoptera spp., white grubs, and the tree cricket or chacuatete, Idiarthron subquadratum S. and P., also present problems. 

Banana borers destroy portions of the rhizome of the plant by tunneling and feeding in the grub stage. This results in tip-over of the plant as its fruit increases in size, but before it reaches maturity. Adult borers are active outside of the plant. At this stage they can be killed by dieldrin, aldrin, and heptachlor, but not by DDT. Borers are widespread and the population is kept down by clean cultivation, but even so fruit losses are considerable.
