I've got some pumpkin plants in my yard and am having trouble with the blooms. The buds appear all nice and everything. But when the pretty yellow flowers are supposed to bloom they don't. The tips shrivle up but the base of the petals stays in tackt. I forced one open to see what was going on and I found some really nasty round translucent orange things in it. Has some kind of nasty bug laid its eggs in my pumpkin flower and if so is this keeping them from opening? What can I do about this?
