Abstract

1. 1. 2-Methyl-1,4-benzoquinone (MBQ), 2-ethyl-1,4-benzoquinone (EBQ) and 1-pentadecene (PD) concentrations in Tribolium confusum and T. castaneum were found to be extremely low in newly eclosed adults (<2.0 μg/insect). The levels of all three compounds increased with age until 20-30 days after eclosion, after which time the concentrations were maintained or declined slowly. 2. 2. In 30-day and older adults, females of both species routinely contained higher levels of MBQ, EBQ and PD than males of the same age. 3. 3. Each 30-day adult T. confusum or T. castaneum contained 35-46 μg substituted p-benzoquinone plus 14-24 μg PD. 4. 4. The odoriferous secretion of 30-day adults had a p-benzoquinone composition of 44% MBQ and 56% EBQ for T. confusum and 50-51% MBQ and 49-50% EBQ for T. castaneum.
