Aggregation in Aphis fabae scop. II. Visual components
Animal Behaviour, 1966Summary An examination was made of the behaviour of apterous A. fabae alienicolae in a number of simple visual situations representing the different components of the visual situation presented by a live stationary aphid. o 1. Most walking aphids approached black objects in a manner typical of the simple optomotor behaviour which mediates ‘form ...

Effects of dietary and gaseous fluoride on the aphid Aphis fabae
Environmental Pollution, 1998A large proportion of leaf fluoride consists of surface deposits and a sucking herbivore would be expected to take in a smaller load of fluoride in its food than a chewing herbivore. In these experiments, fluoride was applied aerially, through the leaves, and systemically, via the roots, to compare uptake by aphids and effects on their fecundity ...

Walking and take‐off in Aphis fabae.
Physiological Entomology, 1978ABSTRACT. Illumination either from one side or alternating between the two sides induced aphids to turn towards the light and also delayed their take‐off as compared with illumination from the front. Illumination from in front or from both sides simultaneously delayed take‐off as compared with dorsal ...

Biologia, 2016
Aphis craccivora and Aphis fabae were found to infest broad bean in Egypt. Aphis craccivora was found to be more dominant than A. fabae; A. craccivora was collected from nine locations that represented different agroecosystems in Egypt. At the same time, A. fabae was found in one location only. Single Nucleotide Polymorphisms (SNPs) in mtDNA Cytochrome

Walking and take‐off in Aphis fabae.
Physiological Entomology, 1977ABSTRACT. A walking aphid ready to emigrate is directed by light, gravity and mechanical stimuli to the upper and outer parts of the plant. There, the new conditions enhance the probability of take‐off, as a kinetic response, but the precise moment at which the aphid stops walking and takes flight does not ...

The photoperiodic counter in the black bean aphid, Aphis fabae
Journal of Insect Physiology, 1994Abstract The photoperiodic counter mechanism in the black bean aphid, Aphis fabae, was analysed by exposing newly-born, presumptive gynoparae to a variety of photoperiodic regimes at 15°C, and by the development of a model. It was shown that the counter accumulated long as well as short scotophases and that the “inductive strength”, or “value”, of ...
