V1brat0rs for Ensuring All Your Cucumber Needs

Bug G. Membracid recently had a radio show appearance!  (Is it called an “appearance” when you’re on a wireless programme and no one can see you?  Nevermind.)

But it featured her line about honeybees being ‎”little flying phalluses” – which is really funny when you remember that worker honeybees are girls!

That in turn reminded me of a story during a horticultural study tour to a Dutch production greenhouse …

Tomatoes and peppers do not need insects to transfer pollen between flowers, as the flowers are “perfect” (have both male & female parts). But for the pollen to get moved/bumped from the pistils to the stigma there still needs to be some kind of wind or other vibration.

There’s not enough wind for this to naturally happen (or rather, efficiently happen) in a greenhouse, especially when the panes are shut to the weather. So it used to be that the operators would equip their greenhouse workers with *little vibrating wands* (oh yes), which they used to buzz-pollinate Every. Single. Fresh. Flower. (Insert inevitable sniggers from the undergrads.) Of course, that’s a lot of paid worker hours.

Nowadays the thrifty Dutch use bumblebees, who work for much cheaper wages of cardboard nesting boxes and some supplemental nectar. The big, gentle bees still visit all the flowers for the pollen, and resultant heavy buzzing results in flower fertilization for good crops.

 

[N.B.  Derf; “cucumbers in the title is incorrect – they DO need to be insect pollinated! Except of course for the parthenogenetic cukes, which basically set fruit by a sort of “virgin birth” process…]
