Synthesis of Biologically Active and Environmental Friendly Insect Pesticides: Pheromones

Abstract

There is a continuous fight with insects and herbs by utilizing pesticides in agricultural productions. Besides their insect killing benefits, these chemicals are extremely harmful for other living things. Recently, pheromones are being suggested as an alternative to these harmful chemicals, especially for the preservation of air, water and soil. These are the secretion of insects used for the comunicating each other by perceiving that secretion. The most important problem with such an application is the synthesis of these substances. Pheromones have ability to select the harmful insects and provide opporunity to kill them. Therefore, in this study, synthesis of two pheromones are studied for the harmful insects cotton- and apple-worms. Under laboratory conditions, synthesis method was developed for biologically active substance transtrans- 8,10-dodecadien-1-ol. Then its suitable aldehyde and ester derivatives were also synthesized.
