A neuron (green and white) in an insect brain (blue) Insect cognition describes the mental capacities and study of those capacities in insects. The field developed from comparative psychology where early studies focused more on animal behavior. [1] Researchers have examined insect cognition in bees, fruit flies, and wasps.
Circular dendrogram of feeding behaviours. A mosquito drinking blood ( hematophagy) from a human (note the droplet of plasma being expelled as a waste) A rosy boa eating a mouse whole. A red kangaroo eating grass. The robberfly is an insectivore, shown here having grabbed a leaf beetle. An American robin eating a worm.
Oligophagy refers to the eating of only a few specific foods, and to monophagy when restricted to a single food source. [1] The term is usually associated with insect dietary behaviour. [2] Organisms may exhibit narrow or specific oligophagy where the diet is restricted to a very few foods or broad oligophagy where the organism feeds on a wide ...
Polyphaga is the largest and most diverse suborder of beetles. It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species discovered thus far. Key characteristics of Polyphaga are that the hind coxa (base of the ...
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Ceroplastes ceriferus is a polyphagous insect, meaning that it feeds on a wide variety of different plants. It has been recorded as utilising plants in 108 genera in 60 different families as hosts . These include such cultivated crops as apple , pear , plum , citrus , mango , tamarind , fig , pomegranate , avocado , tea , coffee , squash and ...
Animal cognition. A crab-eating macaque using a stone tool to crack open a nut. Experiments like the string-pulling task performed here by a Carib grackle provide insights into animal cognition. Animal cognition encompasses the mental capacities of non-human animals including insect cognition.
In biology and medicine, a host is a larger organism that harbours a smaller organism; [ 1] whether a parasitic, a mutualistic, or a commensalist guest ( symbiont ). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes ), cells harbouring pathogenic (disease ...
