Concentrations of substituted p-benzoquinones and 1-pentadecene in the flour beetles Tribolium confusum J. du Val and Tribolium castaneum (Herbst)


, : Concentrations of substituted p-benzoquinones and 1-pentadecene in the flour beetles Tribolium confusum J. du Val and Tribolium castaneum (Herbst). Comparative Biochemistry and Physiology, B 61(1): 25-28

Concentrations of 2-methyl-1,4-benzoquinone (MBQ), 2-ethyl-1,4-benzoquinone (EBQ) and 1-pentadecene (PD) in Tribolium confusum Duv. and T. castaneum (Hbst.) were found to be extremely low in newly emerged adults (<20 mu g/insect). The levels of all 3 compounds increased with age until 20-30 days after adult emergence, after which time the concentrations were maintained or declined slowly.

Interarch occlusal relationships are defined by temporomandibular joint (TMJ) position. Determination of the most physiologic joint position is a logical prerequisite for occlusal analysis. Existing classification systems for occlusion do not cons...
