The disruption of the trail‐based communication system of eastern tent caterpillars (ETC) (Malacosoma americanum) and forest tent caterpillars (FTC) (M. disstria) by spraying host trees with a trail pheromone mimic caused the disintegration and collapse of young colonies. A 1‐ppm formulation of 5β‐cholestan‐3‐one or a control formulation was sprayed on trees either before or after eclosion of the caterpillars in the spring. For pre‐eclosion trials, an average of 92% of the FTC colonies on… 
Larval Pheromone Disrupts Pre-Excavation Aggregation of Cactoblastis cactorum (Lepidoptera: Pyralidae) Neonates Precipitating Colony Collapse
The potential for managing pest populations of caterpillars employing this target-specific alternative to conventional pesticides is discussed.
Response of the neonate larvae of Cactoblastis cactorum to synthetic cactoblastins, a newly identified class of pheromonally-active chemicals found in the caterpillar’s mandibular glands
The characterization, synthesis, and bioassays of a family of 3-acyl fatty acid methyl esters (which is named cactoblastins), a chemically distinct group of mandibular gland compounds that also elicit trail following behavior are reported.
Trail Marking by Caterpillars of the Silverspot Butterfly Dione Juno Huascuma
It is shown that the silk was neither adequate nor necessary to elicit trail following behavior of caterpillars of the nymphalid silverspot butterfly that feed gregariously on Passiflora vines in Mexico.
Biology and Management of the Forest Tent Caterpillar (Lepidoptera: Lasiocampidae)
The forest tent caterpillar is a widespread defoliator that is native throughout most of the continental United States and Canada south of 61°N latitude and its potential to become more important in a warmer climate warrant greater attention to its population dynamics and control options.
The Ancient Chemistry of Avoiding Risks of Predation and Disease
This work hypothesized that necromones are a phylogenetically ancient class of related signals and predicted that terrestrial Isopoda would avoid body fluids and corpses using fatty acid “necromones,” and predicted a priori that social caterpillars (lacking known dispersants) would be repelled by their own body fluid and unsaturated fatty acids.
The potential for monitoring and control of insect pests in Southern Hemisphere forestry plantations using semiochemicals
The value of semiochemicals as an environmentally benign and efficient approach to managing forest plantation pests in the Southern Hemisphere seems obvious, but there is a lack of research capacity and focus to optimally capture this opportunity.
Natural History of the Processionary Moths (Thaumetopoea spp.): New Insights in Relation to Climate Change
It is difficult to find a genus of Lepidoptera showing the high variability of life history traits observed in Thaumetopoea, but in one special case a recent switch has been detected even within one species, the pine processionary moth, indicating that the natural history traits are constantly evolving at a fast rate.
Women show enhanced attractiveness ratings and neural processing of male faces associated with male chemosensory signals
This study stresses the role of AND as a human chemosignal in implicit social communication and demonstrates its effectiveness in modulating emotional learning.


Colony survivorship of social caterpillars in the field: a case study of the small eggar moth (Lepidoptera: Lasiocampidae)
We investigated survivorship of 100 caterpillar colonies of the tent-building central place-foraging moth, Eriogaster lanestris. Our aim was to demonstrate if survival patterns match those reported
Identification and behavioral assays of the trail pheromone of the forest tent caterpillar, Malacosoma disstria Hübner (Lepidoptera: Lasiocampidae)
Behavioral assays show that the steroid 5β-cholestan-3-one, isolated from the abdomen of the larva of the forest tent caterpillar (Malacosoma disstria), constitutes the chemical basis of trail
Trail Marking by the Larva of the Madrone Butterfly Eucheira socialis and the Role of the Trail Pheromone in Communal Foraging Behavior
The study shows that Eucheira employs a relatively unsophisticated system of trail-based communication and does not recruit to food, which appears to represent an early stage in the evolution of cooperative foraging that is derived from, and motivationally linked to, conflict behavior.
Argentine Ant (Hymenoptera: Formicidae) Trail Pheromone Enhances Consumption of Liquid Sucrose Solution
It is found that the Argentine ant, Linepithema humile (Mayr), trail pheromone, could enhance recruitment to and consumption of liquid sucrose solutions and was enhanced by 29%.
Chemical trail marking and following by caterpillars ofMalacosoma neustria
The chemical activity of both recruitment and exploratory trails degrades slowly, suggesting that the trail pheromone of Malacosoma neustria is a nonvolatile substance.
Trail-following behavior and natural history of the social caterpillar of Arsenura armida in Costa Rica (Lepidoptera: Saturniidae: Arsenurinae).
L Laboratory studies show that larval trail-following is elicited by surface cuticular material collected by wiping from the venter and dorsum of the abdomen of A. armida caterpillars, the first published demonstration of pheromone-based trail- Following by a saturniid.
Communal Foraging Behavior and Recruitment Communication in Gloveria sp.
The difference in the efficiency with which caterpillars of Gloveria and M. americanum recruit nestmates to food evolved in response to differences in the spatial distribution of their food supplies, postulates.
Elective recruitment by the eastern tent caterpillar (Malacosoma americanum)
Trail following and recruitment: Response of eastern tent caterpillarMalacosoma americanum to 5β-cholestane-3,24-dione and 5β-cholestan-3-one
The study shows that tent caterpillars are highly sensitive to small differences in the amount of monoketone in a trail and can distinguish between new and aged trails prepared from the compound, which constitutes the chemical basis of recruitment communication in this insect.
Identification of trail pheromone of larva of eastern tent caterpillarMalacosoma americanum (Lepidoptera: Lasiocampidae)
Two other species of tent caterpillars also responded positively to the pheromone in preliminary laboratory tests, and 5β-Cholestane-3,24-dione has been identified as an active component of the trail.
