Chemical crypsis in predatory ants

  title={Chemical crypsis in predatory ants},
  author={Christopher Longhurst and Raymond Baker and Philip E. Howse},
The repellent responses of worker termites to ants are determined by the exocrine gland secretions of the latter. Specialized termite predators produce non-repellent aliphatic alcohols as the major components of their mandibular glands, whereas unspecialized con-generics usually produce repellent ketones and aldehydes. 

Predatory behavior in the genusLeptogenys: A comparative study

L. mexicana are attractive at a distance to the isopods Bathytropidae living in the same natural environment, as a consequence, prey capture is possible without foraging for this species.

Ecology of Termites

The ecological role of termites is examined and explored and it is shown that these tiny insects are a center of attraction because they damage the human economy as wood pests.

Behavioural and electrophysiological responses of Liothrips jatrophae (Thysanoptera: Phlaeothripidae) to conspecific extracts and some of its identified compounds

Investigation of the behavioural and electrophysiological responses of the thrips Liothrips jatrophae to conspecific extracts and some of its identified compounds revealed an escape response, accompanied by other behavioural responses, such as rapid sideways movement and lifting of the abdomen and secretion of a drop at the tip of the appendix.

Is the Pirate Really a Ghost? Evidence for Generalized Chemical Camouflage in an Aquatic Predator, Pirate Perch Aphredoderus sayanus

A habitat selection experiment with aquatic beetles is described and results of 11 experiments involving colonizing beetles and ovipositing tree frogs are summarized that provide evidence that pirate perch Aphredoderus sayanus are chemically camouflaged with respect to a diverse array of prey organisms.

Etude eco-ethologique de la prédation chez les fourmis du genreSmithistruma (Formicidae-Myrmicinae-Dacetini) II. Attraction des proies principales (Collemboles)

A study of predation in Smithistruma truncatidens and S. emarginata produces a variety of arguments supporting the hypothesis that the foraging workers attract Entomobryan Collembola, which could be due to an allomone.

The University of Chicago Is the Pirate Really a Ghost ? Evidence for Generalized Chemical Camouflage in an Aquatic Predator

Camouflage occupies a central role in arsenals of both predators and prey and invokes visions of organisms possessing specific characteristics or altering their shape, color, or behavior to blend




Movement of 9‐oxodec‐2‐enoic acid, a queen honeybee pheromone, from one part of a bee to another was studied using material labelled with tritium, causing some difficulty in precise interpretation of the results.

On the significance of certain oscillatory movements of termites

It was found that the Longitudinal Oscillatory Movement occurred after the termites had been disturbed and that it appeared to be a response to a relatively low-intensity stimulus to antennal sensilla.

Cerebral ammonia production during hypoglycaemia in the newborn calf

The effect of insulin hypoglycaemia on cerebral blood flow, and cerebral metabolic rates of glucose, oxygen and ammonia was investigated in the unanaesthetized newborn calf. A net loss of ammonia

Foraging, recruitment and predation by Decamorium uelense (Sanstchi) (Formicidae: Myrmicinae) on termites in Southern Guinea Savanna, Nigeria

A scout ant searches for foraging termites and returns to the nest where it recruits a column of 10–30 ants which attack and immobilize the termites, and a mass recruitment phase is then instigated, with larger numbers of ants retrieving the prey.
