	abstract = {Usinggas chromatography with flame ionization detection (FID) and electroantennographic detection (EAD) in parallel, butanoic acid, skatole, and (E)-2,6-dimethyl-6-octen-2-ol were identified as constituents of the abdominal sex-attracting secretion of the male dung beetle, Kheper subaeneus, which reproducibly elicited EAD responses in male and female antennae. This is the first report of the occurrence of (E)- 2,6-dimethyl-6-octen-2-ol as a natural product, for which the name (E)-subaeneol is proposed. In some experiments, a few other constituents of the secretion also gave reproducible responses in specific male and female antennae but did not elicit responses when the analyses were repeated with other antennae. The major volatile constituent of the secretion, identified as (S)-(C)-2,6-dimethyl-5-heptenoic acid, is one of these EAD-active compounds. Both this compound and (E)-2,6- dimethyl-6-octen-2-ol were synthesized from authentic starting materials for comparison with the natural products.},

	abstract = {Resource-based trade-offs are known to be important in determining investment in both sexual ornamentation and immunity in insects. Because of the strict resource limitation experienced during metamorphosis, we predict that if insects are trading off ornament size and immunity this should be most apparent immediately after eclosion and that the relationship between sexual ornament size and immunity should change with maturation feeding because of the changing patterns of resource availability during this process. We therefore present an investigation into the relationship between morphology, sex, and two measures of immune response (phenoloxidase [PO] activity and encapsulation ability) in the horned beetle Euoniticellus intermedius, imme- diately after eclosion and after maturation feeding. Both measures increased with maturation, with sex differences in PO activity becoming discernable after maturation feeding. PO activity was positively correlated with horn length in male beetles both on eclosion and after maturation feeding, and encapsulation ability was positively correlated with elytra length. We conclude that resource limitation in the pupating insect does have effects on immunity but that this resource limitation does not translate into a measurable trade-off between horn length and immunity. The correlation between horn length and PO activity may arise because both horn length and PO activity are correlated with the same elements of the animal{\textquoteright}s biology that allow some animals both to grow a long horn and to sustain a higher level of PO activity.},
