Human-insect relationships: an ANTless story? children's, adolescents', and young adults' ways of characterizing social insects
Contributor(s):: Sammet, R., Andres, H., Dreesmann, D.
Ants may serve as powerful model organisms for uncovering principles of insect biology and social behavior. The aim of this study was to provide a quantitative analysis of secondary-school students' perceptions and knowledge of ants. It was part of a longitudinal project based on the concept of...
A note on the effect of controlling stable flies ( Stomxys calcitrans ) in the resting activity and pen distribution of dairy cows
Contributor(s):: Vitela, I., Cruz-Vazquez, C., Orihuela, A.
This study investigated the effect of controlling stable flies (Stomoxys calcitrans) on the number of dairy cows lying down and their pen distribution. The study randomly assigned 80 Holstein cows to 1 of 2 groups. The treated group (T) included cows individually sprayed with insecticide when...
Use of conditioned place preference/avoidance tests to assess affective states in fish
Contributor(s):: Millot, S., Cerqueira, M., Castanheira, M. F., Overli, O., Martins, C. I. M., Oliveira, R. F.
Animal welfare has been defined as the balance between positive and negative experiences or affective states. Despite the growing evidence of complex cognitive abilities and the expression of affective states such as pain and fear, very little is known about ability to experience memory based...

Estimating the diet of urban birds: the problems of anthropogenic food and food digestibility
Contributor(s):: Ottoni, I., Oliveira, F. F. R. de, Young, R. J.
A variety of methods exist for assessing the diets of wild birds, each of which has its strengths and weaknesses. The objective of this study was to compare diet data collected in parallel by behavioural observations and faecal analysis from an urban population of Penelope superciliaris...
Resting and social behaviour of dairy heifers housed in slatted floor pens with different sized bedded lying areas
Contributor(s):: Nielsen, L. H., Mogensen, L., Krohn, C., Hindhede, J., Sorensen, J. T.
The hypothesis that an increase in the straw bedded resting area for group housed heifers would increase synchronization of resting behaviour and decrease aggressive and abnormal behaviour was tested. An experiment was conducted on 2 Danish commercial dairy farms with 20 Danish Friesian heifers...
Animal behaviour, animal welfare and the scientific study of affect. (Special Issue: Animal suffering and welfare.)
Contributor(s):: Fraser, D.
Many questions about animal welfare involve the affective states of animals (pain, fear, distress) and people look to science to clarify these issues as a basis for practices, policies and standards. However, the science of the mid twentieth century tended to be silent on matters of animal affect...
Grooming and control of fleas in cats
Contributor(s):: Eckstein, R. A., Hart, B. L.
Oral grooming is common in cats, as in rodent and bovid species where grooming has been shown to be effective in removing lice and ticks. In Experiment 1, we examined the effectiveness of oral grooming in removing fleas which are the main ectoparasite of cats. Elizabethan collars (E-collars)...
Face-fly pest intensity, fly-avoidance behavior (bunching) and grazing time in Holstein heifers
Contributor(s):: Schmidtmann, E. T., Valla, M. E.
In field studies in New York State in 1978-79, the relationship between feeding by adults of Musca autumnalis Deg., and fly-avoidance behaviour (bunching) and grazing time of heifers was examined in herds that were either exposed to the ambient pest intensity levels or treated with permethrin...
Effects of headfly ( Hydrotaea irritans Fallen) infestations and repellents on ear-flicking and head-shaking behaviour of farmed red deer ( Cervus elaphus L.)
Contributor(s):: Woollard, T. H., Bullock, D. J.
The effects of Hydrotaea irritans on farmed red deer in Scotland are described. The degree of irritation by headfly varied with the age and sex of the deer. Yearling hinds had higher ear-flicking rates than either yearling or adult stags. Both sexes of yearlings had higher head-shaking...
Effects of fly disturbance on the behaviour of a population of reintroduced Przewalski horses ( Equus ferus przewalskii ) in Mongolia
Contributor(s):: King, S. R. B., Gurnell, J.
Flies constitute a cost to animals by feeding from them, passing on disease or by preventing them feeding effectively. These costs could be more severe to animals suffering from some kind of stress such as reintroduction as part of a conservation programme. This study focused on the effects of...
Reproductive status and differential response to attacking insects in female reindeer
Contributor(s):: Kojola, I.
In Finland, the activity budgets (i.e. time spent lying, standing, feeding, walking and running) of lactating and yeld (i.e. barren, dry) female wild forest reindeer (Rangifer tarandus fennicus) during gadfly (Tabanidae) attacks were compared on 6 sunny afternoons during mid and late summer in...
Behavior of grazing cattle exposed to small populations of stable flies ( Stomoxys calcitrans L.)
Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Cornelius, P. L.
The authors hypothesized that cattle grazing in the presence of low-level infections of stable flies may offset reductions of grazing time by increasing their rate of herbage intake, and that this may contribute to the determination of economic threshold populations. On 4 consecutive days, 4...
Daily selection of feeding areas by cattle in homogeneous and heterogeneous environments
Contributor(s):: Bailey, D. W.
Plots containing 3 heterogeneous patches that varied in forage quality and quantity, and plots containing 3 homogeneous patches were grazed by yearling steers in a 2-part study. During the 1st trial, steers selected patches from a central decision area, and fences divided the patches. During the...
Face flies ( Musca autumnalis De Geer) and the behavior of grazing beef cattle
Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Bradley, N. W.
Zero, 400 or 800 laboratory-reared adult face flies (Musca autumnalis De Geer), which had been deprived of nutrients and water for 12 h, were released in large (5 m x 5 m x 2 m) screened enclosures each containing one tethered adult Angus beef cow (Bos taurus) grazing tall fescue (Festuca...
Moderation of grazing behaviour of beef cattle by stable flies ( Stomoxys calcitrans L.)
Three concatenated latin squares (4 x 4) were used to evaluate the effects of stable flies on the behaviour of Angus cows grazing in screened enclosures. Four populations (0, 50, 100 and 150) of starved, laboratory-reared stable flies were released into each enclosure at 15 min intervals during 1...
