Feeding responses and food preferences in the tropical, fruit-feeding butterfly, Bicyclus anynana

Journal of Insect Physiology, 2008
In the tropical butterfly Bicyclus anynana (Nymphalidae) essential components of fitness (such as fecundity and longevity) depend to a large degree on exogenous adult-derived nutrients, particularly carbohydrates. We investigated which of the nutrients/compounds found in the adult diet act as feeding stimuli, and whether butterflies show preferences ...

APPARENT FEED PARTICLE SIZE PREFERENCE BY BROILERS

Canadian Journal of Animal Science, 1988
Broiler chicks of different ages were used to study particle size disappearance and the effect of particle size on feed intake. The disappearance of particles larger than 1.18 mm was obvious at all ages. However, it was noticed that at 8 and 16 d disappearance of particles between > 1.18 mm and < 2.36 mm was most pronounced.

Feeding behaviour and host preferences of British mosquitoes

Bulletin of Entomological Research, 1971
The arrival of mosquitoes at human bait under natural conditions could be divided into three behavioural phases, the exploratory, the penetration and feeding periods. The duration of these periods was recorded in Mansonia richiardii (Fie), Anopheles plumbeus Steph., Aedes punctor (Kby.), Ae. detritus (Hal.), Ae. cinereus Mg. and Ae.

Feeding Specialization and Preference in Herring Gulls

The Journal of Animal Ecology, 1986
(1) Previous claims that herring gulls have preferences for particular foods or that they specialize in them have been based on food remains at the nest and repeated observations of tagged individuals. The complex temporal pattern of food availability and the constraints of incubation make such observations hard to interpret.

Feeding preferences of supralittoral isopods and amphipods

Canadian Journal of Zoology, 2000
We examined the feeding preferences of 3 supralittoral crustacean species in the Pacific Northwest of North America. The isopod Ligia pallasii (Brandt, 1833), the rocky-shore amphipod Traskorchestia traskiana (Stimpson, 1857), and the sandy-beach amphipod Megalorchestia californiana (Brandt, 1851) had similar feeding preferences, suggesting that ...

Dynamics of feeding preferences by a predator

Ecological Modelling, 2002
A mathematical model describing the dynamics of food choice by feeding predator is suggested. The model is developed on the basis of the equation proposed by M. Eigen (1971) for the description of natural selection of biological macromolecules. The model is illustrated by classical experiments on selective feeding of fishes.

Feeding preferences of blood-sucking insects

1991
Blood-sucking insects feed from a range of different host animals. For obvious and often painful reasons, we are aware of the fact that many of them feed from mammals, but many other host animals are also exploited including birds, reptiles, amphibians and fish, and even insects, arachnids and annelids (Hocking 1971).

Feeding Preferences and Dietary Specialisation Among Obligate Coral-Feeding Butterflyfishes

2013
[Extract] Coral reef fishes have long been known to exhibit highly specialised patterns of habitat use (e.g., Fautin, 1985; Munday et al., 1997; Gardiner and Jones, 2005), but are generally considered to be highly versatile in their feeding (Ross, 1986; Bellwood et al., 2006c), opportunistically consuming a wide range of different prey.

Feeding Preferences of Triatoma Dimidiata Maculipennis in Yucatan, Mexico

The American Journal of Tropical Medicine and Hygiene, 1977
To determine whether a low preference for human blood by Triatoma dimidiata maculipennis Stal, 1859, the only known vector of Chagas' disease in Yucatan, Mexico, would account for the low prevalence of antibodies to Trypanosoma cruzi in man in the area, the intestinal contents of 924 bugs were tested against antisera to blood antigens of chicken ...
