“…However, the major metabolic fuel for male fire ants appears to be proline (Consoli and Vinson, 2002), rather than diacylglycerol. Also, previous studies indicate that male fire ants have low fat content (Vogt and Appel, 1999).…”

Antennal proteins of the male fire ant (Solenopsis invicta) were analyzed by two-dimensional gel electrophoresis, with the objective of identifying pheromone-binding proteins, which have not previously been found in ant antennae. The major low-molecular weight protein found in the male fire ant antenna was subjected to Edman degradation to determine the N-terminal amino acid sequence. Degenerate PCR primers based on this sequence were used to obtain a cDNA sequence corresponding to the full-length protein sequence. In-gel trypsin digestion followed by MALDI-TOF mass spectrometry and HPLC-ESI/MS/MS demonstrated that the protein gel spot contained only the protein corresponding to the cDNA sequence obtained by PCR. The sequence is similar to apolipophorin-III, an exchangeable lipid-binding protein. Fire ant apolipophorin-III is expressed in the antenna as well as the head, thorax and abdomen.

“…Ontogenetic scaling considers growth trajectories of the relationship between Y and M for a single individual, although crosssectional comparisons of multiple individuals from the same species at different stages of ontogenetic development are more common than longitudinal comparisons in the physiological literature (e.g., 205,280,363,382,389). Static scaling considers the relationship between Y and M among individuals of the same developmental stage within a species, such as within an instar for insects (e.g., 342,408). Evolutionary scaling considers the relationship between Y and M among individuals of different species, again at the same developmental stage.…”

Life on earth spans a size range of around 21 orders of magnitude across species and can span a range of more than 6 orders of magnitude within species of animal. The effect of size on physiology is, therefore, enormous and is typically expressed by how physiological phenomena scale with mass(b). When b ≠ 1 a trait does not vary in direct proportion to mass and is said to scale allometrically. The study of allometric scaling goes back to at least the time of Galileo Galilei, and published scaling relationships are now available for hundreds of traits. Here, the methods of scaling analysis are reviewed, using examples for a range of traits with an emphasis on those related to metabolism in animals. Where necessary, new relationships have been generated from published data using modern phylogenetically informed techniques. During recent decades one of the most controversial scaling relationships has been that between metabolic rate and body mass and a number of explanations have been proposed for the scaling of this trait. Examples of these mechanistic explanations for metabolic scaling are reviewed, and suggestions made for comparing between them. Finally, the conceptual links between metabolic scaling and ecological patterns are examined, emphasizing the distinction between (1) the hypothesis that size- and temperature-dependent variation among species and individuals in metabolic rate influences ecological processes at levels of organization from individuals to the biosphere and (2) mechanistic explanations for metabolic rate that may explain the size- and temperature-dependence of this trait.

SUMMARYWe tested the hypothesis that oxygen delivery from the atmosphere to the tissues becomes more difficult as grasshoppers increase in body size throughout development due to increases in tracheal length. If this is true,then older, larger grasshoppers should have smaller safety margins [higher critical oxygen partial pressures (PO2s)] for oxygen delivery than younger, smaller grasshoppers. We exposed grasshoppers of first, third and fifth instars and adults to decreasing levels of atmospheric O2 and measured their ventilatory responses. Contrary to our prediction, we found that larger grasshoppers had critical PO2s eight times lower than juveniles due in part to their threefold lower mass-specific metabolic rates and their ability to quadruple convective gas exchange. Adults more than doubled abdominal pumping frequency and increased tidal volume by 25% as PO2 decreased fourfold, whereas the youngest juveniles showed no such responses. This study indicates that juveniles may be more susceptible to hypoxia in natural situations, such as exposure to high altitude or restricted burrows. Also, larger size is not necessarily correlated with a smaller safety margin for oxygen delivery in insects.
