Mandibular gland allomones ofDasymutilla occidentalis and other mutillid wasps

Journal of Chemical Ecology, 1980
The mandibular gland secretion of the mutillid wasp,Dasymutilla occidentalis, possesses three short-chained ketones-4-methyl-3-heptanone (4MH), 4,6-dimethyl-3-nonanone (4,6DMN), 4,6-dimethyl-3-octanone (4,6DMO)—and several unidentified compounds. This is the first report of 4,6DMN as a natural product and its synthesis is described.

Allomones confer resistance to Musa paradisiaca L. cultivar Pisanglilin against infestation by Odoiporus longicollis [Oliver] and characterization of Allomones

Allelopathy Journal, 2021
In bioassay guided extraction of pseudostem powder of Pisanglilin by organic solvents we found the larvicidal activity in acetone extract, whose column chromatography by methanol-chloroform mixture separated the extract into 9-fractions, of which the 8th fraction showed larvicidal activity.

Allelochemical Communication in Vertebrates: Kairomones, Allomones and Synomones

Cells Tissues Organs, 2006
Communication between different species by means of chemicals (allelomones) is widespread among prokaryotes, plants and invertebrates. This study reviews data suggesting that allelochemically mediated communication also exists among vertebrates. The work aims to provide a concise, interdisciplinary review of communication mediated by infochemicals ...

A modified allomone collecting apparatus

Journal of Chemical Ecology, 1991
A modified allomone collecting apparatus was designed that could be used under water with a scuba tank. This apparatus provides a simple method of obtaining naturally secreted chemicals from benthic marine organisms at scuba depths, for the first time without the necessity of using a bilge pump.

Allomonal functions of steroid hormone, antheridiol, in water moldAchlya

Journal of Chemical Ecology, 1987
The steroid hormone antheridiol has previously been shown to play a number of key roles in regulating development of the male sex organs, antheridia, of the water moldAchlya ambisexualis. We now demonstrate that synthetic antheridiol can inhibit both sexual (determined by oogonial counts) and asexual reproduction (determined by counts of asexual spores)

A neuropterous larva uses an allomone to attack termites

Nature, 1981
Larvae of Lomamyia spp. (Neuroptera: Berothidae) have been tentatively associated with several types of prey since they were first identified1. In all cases, the assumed prey lived in a confined habitat–an ant nest or termite gallery2. Lomamyia latipennis Carpenter has been the most thoroughly studied of these unusual Neuroptera.

Allomonal secretions in cockroaches

Journal of Chemical Ecology, 1983
We have analyzed the allomonal secretions in 10 species of cockroaches belonging to seven genera and made a detailed reanalysis of these secretions in three other species previously studied. Forty-three products were identified (quinones, phenols, acids, ketones, aldehydes, lactones, hydrocarbons, alcohols and various products).

Nest plundering allomones of the fire beeTrigona (Oxytrigona) mellicolor

Journal of Chemical Ecology, 1988
Ten volatile compounds derived from the cephalic glands of the fire beeTrigona (Oxytrigona)mellicolor were bioassayed for possible allomonal activities facilitating nest plundering. Two diketones, (E)-3-heptene-2,5-dione and (E)-3-nonene-2,5-dione, caused the honeybeeApis mellifera to display avoidance behavior and reduced defensive behavior.

The Role of Pheromones, Kairomones, and Allomones in the Host Selection and Colonization Behavior of Bark Beetles

Annual Review of Entomology, 1982
Bark beetles use a complex chemical communication system to locate a new host, upon which they can feed, mate, and reproduce. Because the food resource may be either ephemeral (7) or not available until the tree dies, these beetles have evolved a pheromone that elicits behavior resulting in aggregation of the population on the new host. This population
