Strawberries are not considered true berries by scientists. They are called "pseudocarps", and the part of a strawberry that we eat is actually the "receptacle", the part of the plant that produces the fruit (rather than the fruit itself).
A: PEDICEL or stem.
B: PITH. Spongy tissue in the center; less flavorful. The size of the pith varies by variety.
C: ACHENE. Most people think these are seeds, but actually they are the TRUE FRUIT of the strawberry, similar to a sunflower seed and its shell. A medium-sized strawberry has about 200 achenes.
D: CALYX. Also called the "cap", the calyx is made up of SEPALS which look like small leaves.
E: VASCULAR BUNDLE. This "string" of lighter-colored flesh connects the pith with an achene.

Wouldn’t it be wonderful if we could get bees to deliver an effective agent to strawberry flowers that would protect them from infection by Botrytis cinerea? Researchers in Sweden used bumblebees to pick up a biocontrol fungus (Aureobasidium pullulans) and deliver it to strawberry flowers, reducing Botrytis fruit rot by 45% and doubling the fruit’s shelf life.
That’s impressive, especially in light of our own results with the same biocontrol fungus where it showed no efficacy against Botrytis fruit rot under field conditions.
So, what’s going on?
Why such a big difference between their results and ours?

It’s widely accepted that there are four major diseases in California strawberry caused by these soilborne pathogens:
✔ Macrophomina root rot
✔ Fusarium wilt
✔ Verticillium wilt
✔ Phytophthora crown and root rot
❓What we did not know is which of these four pathogens are most common?
