Unfortunately, the gubment, colleges and universities haven't funded an in depth study on this subject, and likely will not, favoring studies of the sex life of an anopheles mosquito instead. Consequently, we can only go with what little, local knowledge we possess on the subject. Now, if someone has a published scientific study on this, I would love to see it. smile
