Wasps and yellow jackets do essentially no pollination....they may visit a flower on occasion, but because they have essentially no hair on their bodies, they don't pick up and transfer pollen from one flower to another; nor do they return to their nest with pollen on their bodies and get it transferred inhive to another bee who will vist another apple blossom. There are solitary bees that are efficient pollinators, but seldom are there enough of them in an orchard to make a significant dent....unless they are brought in intentionally...the Blue Orchard bee, the mason bee...those that are managed specifically for this purpose.

How much pollination of tree fruit is done by wasps and yellow jackets and do they have the same water requirements? Seems I am seeing more of them than bees. Are they predators of our pollinating bees? Thanks, D. Del Boca N.W.

One thing to check is early morning, when new blossoms open, before they have a chance to dehise. I haven't done much with apples in many years, but used to a lot, and found this to be true...but I don't recall the varieties. What led to this was a grower saying our bees weren't doing their job...so we were out before dawn, measuring flight activity when it began, and what trees it was on....just fyi. And you are exactly correct on providing water as close to the bees as reasonable. One caution...long ago it was customary to empty sprayers in orchards when done spraying....although this isn't the norm, it can, if practiced, be deadly if bees need, and don't have other water. Another fyi.

Best thing a grower can do is make sure a water supply the bees can access without drowning is close by.

Here in central Massachusetts we have had temps in the 88 degree range for the last 3 to 4 days. Have not seen much bee activity in McIntosh at all. We see some activity in the Cortland, Delicious etc. Growers that get bees from different suppliers are noticing the same thing. Can it get too hot and make the pollen unattractive to the bees?
