Members of a wild group of wedge-capped capuchin monkeys (Cebus olivaceus) intentionally anoint themselves with millipedes (Orthoporus dorsovittatus). Chemical analysis revealed these millipedes secrete two benzoquinones, compounds known to be potently repellent to insects. We argue that the secretion that rubs off on the monkeys in the course of anointment provides protection against insects, particularly mosquitoes (and the bot flies they transmit) during the rainy season. Millipede secretion… 

Benzoquinones from millipedes deter mosquitoes and elicit self-anointing in capuchin monkeys (Cebus spp.)

Female yellow fever mosquitoes were presented with two millipede secretory compounds and exhibited fewer landings, fed less frequently, and flew more frequently (a possible indication of repellency) in the presence of membranes treated with benzoquinones than with controls.

Anting in a Semifree-ranging Group of Cebus apella

It is argued that anting behavior in tufted capuchins fits the hypothesis of protection against ectoparasites.

Wild Blonde Capuchins (Sapajus flavius) Perform Anointing Behaviour Using Toxic Secretions of a Millipede (Spirobolida: Rhinocricidae)

The social nature of the behavior and time of the observations (mosquito season), suggest that social bonding and mosquito avoidance is linked to the anointing behavior of the monkeys.

Anointing with commercial insect repellent by free-ranging Cebus capucinus in Manuel Antonio National Park, Quepos, Costa Rica

Fur rubbing or anointing is a well known behavior in capuchin monkeys (Cebus and Sapajus), and may have medicinal and/or social functions. Observations of anointing in capuchins have recorded the

Prey-rolling behavior of coatis (Nasua spp.) is elicited by benzoquinones from millipedes

Coatis (Nasua spp.), gregarious, omnivorous carnivores that range in forests from the southwestern USA to south America, dispatch millipedes by rolling them on the ground using rapid, alternating

Distribution of the Chuuk Islands Giant Millipede, Acladocricus setigerus (Spirobolida: Rhinocricidae), and Identification of Its Defensive Compounds

The spirobolidan millipede Acladocricus setigerus (Silvestri, 1897) grows to at least 155 mm long and is so far known only from Chuuk Islands, Micronesia; the major compounds, identified here for the first time, are benzoquinones.

Potential self-medication by brown titi monkeys, Plecturocebus brunneus, in an urban fragment forest in the Brazilian Amazon

The presence of dogs, cats and human settlements may contribute to an increase of ectoparasites, making a potential self-medication function of fur rubbing in this primate species plausible.


It is indicated that benzoquinones appropriated via anointing may reduce the tick loads of free-ranging animals, although key questions remain on the amounts of these compounds available to and effectively appropriated by anointed animals.

Chemical odorant of colonial seabird repels mosquitoes.

This report is the first empirical evidence for an endogenous mosquito repellent in birds and shows that constituents of the aldehyde odorant are broad spectrum in efficacy against ectoparasitic arthropods of birds.



Defensive Secretions of Millipeds

The millipeds, comprising the arthropodan class Diplopoda, are an ancient group dating back to Devonian times, and they have held their own to this day, despite the evolutionary diversification of those very animals, the vertebrates, insects, and arachnids, that have come to include the primary predacious enemies of milliped.


This review treats successively the large genus Cutere­ bra, the monotypic but economically and medically significant genus Der­ matobia, and the four other cuterebrid genera, followed by a listing of cited references.

Chemical Basis for Aspilia Leaf-Swallowing by Chimpanzees: A Reanalysis

Analysis of three North American taxa found high concentrations of thiarubrines and thiophenes in the roots of Eriophyllum lanatum and Chaenactis douglasii, and the roots and leaves of Ambrosia chamissonis.

Effects of bot fly (Alouattamyia baeri) parasitism on a free‐ranging howler monkey (Alouatta palliata) population in Panama

The annual pattern of howler mortality results from a synergistic effect between the age, physical condition, and fat reserves of parasitized individuals, the size of the larval burden, and increasing dietary stress as the rainy season progresses.

Infanticide in wedge-capped capuchin monkeys, Cebus olivaceus.

Three cases of infanticide are reported from a well-studied population of wedge-capped capuchin monkeys, Cebus olivaceus, located in the Venezuelan llanos. For each case, we examined the social

Defensive secretion of the millipede Floridobolus penneri.

Six quinones were identified from the defensive secretion of the millipede Floridobolus penneri, and no sex difference in the composition of the secretion was noted.

Seasonal variation in use of time and space by the wedge-capped capuchin monkey, Cebus olivaceus : implications for foraging theory

The relationship between the foraging behavior of a group of wedge-capped capuchin monkeys Cebus olivaceus and the abundance and spatial distribution of resources, was examined in a highly seasonal gallery forest in central Venezuela during 14 months to evaluate the behavioral mechanisms regulating group foraging.

Antibiotics from basidiomycetes

Three new antibiotically active metabolites were isolated from cultures of the fungus Pleurotellus hypnophilus, and the mode of action was compared with the antimicrobial and cytotoxic effects of complicatic acid and other α-methylene ketones and lactones from higher plants.

The 2-methoxy-5-methyl-1,4-benzoquinone compound isolated from mycelial cultures of Lentinus adhaerens inhibits the U46619-induced aggregation of human blood platelets and is a new thromboxane A2 receptor antagonist.
