ABSTRACT
Experimental techniques that we have found useful during our studies of insect blood-feeding behaviour are reviewed. Some of the principal findings resulting from these techniques are discussed. Where directly applicable, the work of others is included, but no complete review of the subject has been attempted.
Subject(s)
Feeding Behavior/physiology , Insect Bites and Stings , AnimalsABSTRACT
This paper continues a discussion of approaches and methodologies we have used in our studies of feeding in haematophagous insects. Described are techniques for directly monitoring behaviour: electrical recording of feeding behaviour via resistance changes in the food canal, optical methods for monitoring mouthpart activity, and a computer technique for behavioural event recording. Also described is the use of "flow charts" or "decision diagrams" to model interrelated sequences of behaviours.

Se tratan diversas técnicas de cría y alimentación de triatominos en el laboratorio, analizándose las ventajas, desventajas y resultados, tanto de aquellas técnicas que requieren animales vivos, como de las que emplean alimentación artificial en base a dietas con sangre de un vertebrado tratada de diversas formas, y que, generalmente, tiene lugar a través de membranas artificiales, y las que utilizan dietas no nutritivas. Se mencionan técnicas de estudio del comportamiento alimentario de los triatominos y sus posibles aplicaciones para la investigación

Se revisa literatura existente sobre alimentación, procesos post-alimenticios y vuelvo de triatominos (Rhdnius prolixus, Triatoma infestans y Panstrongylus megistus fueron las especies más estudiadas), considerándose aspectos de la conducta alimentaria, localización de huéspedes, digestión, nutrición, metabolismo, excreción, requerimientos nutricionales, comensalismo (simbiontes), efectos de la carencia de alimentos, papel de la alimentación en el desarrollo, ecdisis y reproducción; y aspectos del vuelo: iniciación, balancehídrico durante el mismo y metabolismo (mencionándose el papel de los aminoácidos como fuente energética)
