Aphid update:
If you recall, I had an aphid infestation on some of my 2nd crop sweet corn tassels. I learned that aphids secrete a sticky sweet substance which sticks to the plant & attracts ants to the area. I'm not sure exactly why attracting the ants is beneficial to the aphids, but the ants get a good meal out of the substance anyway. I did have lady bugs & an assortment of other beetles feeding on the aphids, just not a lot of them. Upon the discovery of aphids, I did blast them off some of the plants with a high pressure stream of water which did remove the majority of the aphids & the sticky substance that was on the tassels. I'm glad I did this, because I later found out that the sticky substance can actually create mold problems & I needed that pollen for my corn silks.
I checked on the corn today, & it is entirely aphid free, sticky substance free, mold free, & doing great. The tassels have attracted about a dozen sweat bees per plant. I wonder what that relationship is about? Are they there for pollen, did they eat the aphids, or is it simply a convenient perch to rest?
Dirty hands + a sweaty handkerchief = hope for the future.
