    The sex pheromone glands ofDermacentor variabilis (Say) andDermacentor andersoni stiles (1981)
    Springer
    Journal of chemical ecology 7 (1981), S. 345-357

    Notes: Abstract Evidence is presented indicating the presence of the tick sex pheromone, 2,6-dichlorophenol in lipid droplets in the foveal glands ofDermacentor variabilis (Say) andDermacentor andersoni Stiles. The pheromone appears to be dissolved in the lipid droplets. The droplets consist of neutral lipids, mostly triacylglycerides and cholesterol esters. The esterified fatty acid profiles of foveal gland triacylgylcerides are different from those of other tissues examined or reported for other ticks. The percentage of shorter chain, mostly saturated fatty acids were decreased, while the longer chain polyunsaturated fatty acids were increased. The biological advantages of lipid solution for storage, translocation, and release of the sex pheromone from the female tick are discussed.

    Biochemical adaptations of the bruchid beetle,Caryedes brasiliensis tol-canavanine, a higher plant allelochemical (1983)
    Springer
    Journal of chemical ecology 9 (1983), S. 803-815 
    Details
    ISSN: 1573-1561
    Keywords: Caryedes brasiliensis ; Coleoptera ; Bruchidae ; l-canavanine ; l-canaline ; Dioclea megacarpa (Leguminosae) ; allelochemicals ; detoxification ; adaptation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract This communication reviews recent biochemical studies ofl-canavanine that have provided significant understanding of the interaction between the seed ofDioclea megacarpa (Leguminosae) and the bruchid beetleCaryedes brasiliensis (Bruchidae). The principal biochemical bases are proposed for: canavanine toxicity, the ability of the beetle larvae to adapt to its presence, the metabolic sequestration and detoxification of ammonia, and the potential amplification by microbial symbionts of the beetle's abilities to adapt to toxic components of the host.
