Plant-derived pyrrolizidine alkaloids play an important role in the biology of salt marsh moth, Estigmene acrea (Lepidoptera: Arctiidae). They are phagostimulants for larvae and they stimulate growth development adult male androconial organs called coremata. In this study, we have shown that alkaloid monocrotaline N-oxide (MNO) fed to also affects courtship behavior males. Males a diet containing MNO display their coremata while males on same without rarely display. This explains why it has...

Analysis of the extracts ant Myrmicaria melanogaster from Brunei in Indonesian archipelago by GC-MS and GC-IR revealed presence five new alkaloids, identified as (9Z)-3-propylindolizidine (1), cis- trans-2-butyl-5-propylpyrrolidine (2 3, respectively), (10E)-3-butyllehmizidine (7), (5Z,8Z,9Z)-3-butyl-5-propyl-8-hydroxyindolizidine (10a), whose structures were established comparison with synthetic samples. In addition monoterpene hydrocarbons β-pinene, myrcene, limonene detected along all...
Significance We document the behavioral interactions among three ant species: a fungus-growing host ant, permanently associated parasitic guest and raiding agro-predator ant. show that presence of ants becomes advantageous when are attacked by raider ants, because use alkaloid venom to defend their colony. Furthermore, detection odors is sufficient discourage scouts from recruiting nestmates colonies. Guest likely have evolved this protective behavior they also perish colony dies.
With fossil representatives from the Silurian capable of respiring atmospheric oxygen, millipedes are among oldest terrestrial animals, and likely first to acquire diverse complex chemical defenses against predators. Exploring origin adaptive traits is critical for understanding evolution Earth's biological complexity, defense serves as an ideal study system. The classic explanation complexity by gradual increase simple complex, passing through intermediate "stepping stone" states. Here we...
The crested auklet, Aethia cristatella, emits a class of aldehydes shown to be potent invertebrate repellents when used by heteropterans against their predators. Our aim was determine the efficacy these mosquitoes in laboratory. Synthetic analogues auklet odorant were strongly repellent controlled laboratory trials. Furthermore, similar previous reports for commercial mosquito repellents. These results, combination with previously published study, show that constituents aldehyde are broad...

A variety of alkaloids, most which occur or are structurally related to alkaloids that in skin glands dendrobatid poison frogs, were assayed for antimicrobial activity against the Gram-positive bacterium Bacillus subtilis, Gram-negative Escherichia coli and fungus Candida albicans. Certain pyrrolidines, piperidines decahydroquinolines, perhydro-histrionicotoxin, a synthetic pumiliotoxin active B. subtilis. Only 2-n-nonylpiperidine was E. coli.

Analyses of the chief volatile constituents defensive secretions three oplionids were carried out. Leiobunum nigripalpi produces closely related C7 compounds: E-4-methyl-4-hexen-3-one(I), 4-methylhexan-3-one(II), and 4-methylhexan-3-ol(III), along with E-4-methyl-4-hepten-3-one(IV), E,E-2,4-dimethylhexa-2,4-dienal(IX), a minor, unidentified component. L. leiopenis secretion contains 4-methylheptan-3-one(V), E,E-2,4-dimethylhexa-2,4-dien-1-ol(VII), E,E-2,4-dimethylhepta-2,4-dien-1-ol(VIII)....
The exocrine secretion of the "stinkpot turtle," Sternotherus odoratus, discharged by animals in response to disturbance, contains four omega-phenylalkanoic acids (phenylacetic, 3-phenylpropionic, 5-phenylpentanoic, and 7-phenylheptanoic). last two these are new natural products. first powerfully malodorous responsible for stench fluid. Lesser components, including several aliphatic acids, also present. Only a few milligrams turtle at any one time. Although bioassays with fish suggest that...
