Özet:
The range of Agrilus planipennis Fairmaire (Emerald Ash Borer) has been increasing over the last decade since their discovery in North American in 2002. Their range increase has been caused by human activity, such as the transportation of lumber and fire wood from quarantined areas. Scientists have been determined in recent years to come up with a plan to halt the spread of the EAB. In order to do this, we must understand how they allocate nutrients during their life stages. Little is known about their nutritional ecology, particularly changes the acquisition and storage of nutrients during major transitions of their life cycles. My study tested three scenarios for the allocation of resources acquired by juvenile and adult EAB: 1) resources for reproduction come strictly from the adult's diet and reserves acquired during the larval stage are used for maintenance, 2) Resources retained from larval reserves are devoted to reproduction, 3) Nutrients acquired by larvae and adults are allocated towards reproduction. To test these scenarios, I measured levels of protein, carbohydrates, amino acids, and lipids from eggs, J- larvae, emerging adults and post-mated adults. Eggs and J-Larvae were found to be significantly different than the adult EAB in level of amino acids, lipids and carbohydrates. The Eggs were not different in protein compared to unmated males and females, and J-Larvae were not different in protein levels compared to the mated males and females. It was determined that the EAB did not follow just one scenario but a combination of two of them. The J-Larvae synthesized their amino acids into protein in their unpaired counter parts. The protein synthesis was a result of larvae reserves following part of scenario 2; adults allocated the rest of the nutrients required for reproduction and egg production, following scenario 3.
