dc.description.abstract | The Comstock mealybug (CMB) Pseudococcus comstocki (Kuwana) (Rhynchota Pseudo-coccidae) is a highly polyphagous species widespread in Central Asia, Eastern Europe, USA and other regions. It is one of the most serious pest of apple, pear and other agricultural crops. Scientific investigations and field tests demonstrated that 2,6-dimethyl-l,5-heptadien-3-yl acetate is the most attractive one for these species. According to literature, synthesis of this pheromone suffers from low overall yield (cca 9%), as well as increases the self-cost of this compound. Hereby, we report an efficient synthetic route for obtaining of 2,6-dimethyl-l,5-heptadien-3-yl acetate with total yield more than 60%. | en |
dc.description.abstract | Specia Rhynchota Pseudococcidaeeste o insectă (răspândită în Asia Centrală, Europa de Est, SUA şiînalte regiuni),care distruge culturile agricole. Investigaţiile şi testările pe teren au demonstrat că cel mai eficient remediu în lupta cu acest dăunător este atractantul 2,6-dimetil -l,5-heptadien-3-acetat. Conform datelor din literatura, sinteza atractantului implică o serie de dificultăţi însoţite de reducerea considerabilă a randamentului totalizant (cca 9%) şi,respectiv,de termină mărirea sinecostului acestui produs.În studiul de fa ţă propunem o cale eficientă şi economicoasă de obţinere a 2,6-dimetil-l,5-heptadien-3-acetatului cu unrandament general de peste 60%. | |
