> I'll not write a long e-mail because, as I wrote to some of you in private

> idea is may be 20 years old.
> Please find in attachment the figure of a recent paper written by Roger
> Seymour (Univ. of Adelaide, Australia) and myself on the thermogenesis of
> Philodendron melinonii.
> The paper is a bit complicate but the this figure present a real picture
> and the equivalent IR picture of the same inflorescence during
> thermogenesis (heating phase).
> Hence you can see the inflorescence like an insect could "see" it through
> its IR receptors. Flashy!!! There is no question if the pollinating beetles
> have IR receptors they can detect a heating inflorescence. The questions
> now to study are:
> Do Cyclocephala beetles have IR receptors ?
> What are their sensibility & efficiency?
> Are IR radiations used as a guide by Cyclocephala beetles to find the
> inflorescences to visit or are odors sufficient ?
>
> To finish, I would like to say that I have the honor to be the IAS speaker
> during the Annual show next September, and that I'll pleased to tall you
> some "nice "stories around thermogenesis and IR radiations.
>
> All the best,
