Lueheia karachiensis, new species (Acanthocephala: Plagiorhynchidae) from the small intestine of a bird (Accipiter badius cenchroides (Serertzov) is being described. The new species possesses the following characters viz. Body elongated measuring 13.60 by 0.72-1.04. Broadest body width at the end of proboscis receptacle or at level of anterior testis. Proboscis short, sub-globular with 20-24 ro...

Abstract Background Butterflies make an important part for plant-pollinator guild. These are nectar feeder or occasionally pollen and thus proboscis of the butterfly species considered as one most variable in relation to collection food from plants. In butterfly-plant association, source is principally determined by quality nectar, corolla length, quantity. For butterfly, uptake length because ...

Mathematical theory predicts that small changes in container shape or in contact angle can give rise to large shifts of liquid in a microgravity environment. This phenomenon was investigated in the Interface Configuration Experiment on board the NASA USML-2 Space Shuttle flight. The experiment’s “double proboscis” containers were designed to strike a balance between conflicting requirements of ...

Plasticity in the honeybee brain has been studied using the appetitive olfactory conditioning of the proboscis extension reflex, in which a bee learns the association between an odor and a sucrose reward. In this framework, coupling behavioral measurements of proboscis extension and invasive recordings of neural activity has been difficult because proboscis movements usually introduce brain mov...
