When I first noticed yellow aphids on the undersides of some leaves on the mystery marrow plant, I sighed, looked at the abundance of leaves, and decided there were enough leaves to share with the invading insects. It’s one of the most difficult decisions to make when you’re trying to grow your veggies organically and stay pesticide-free.
Unlike my watermelon plants – that were the next to be infested – this hardy plant barely seemed affected, and I forgot about the aphids until I looked closely at the photos I’ve been taking to document the progress of the plant.
There were two white ladybug larvae meandering their way on the new marrow that had just set fruit, and when I looked more closely, I noticed small yellow aphids on the fruit and on the neighbouring leaves. I had completely forgotten about the aphids!
These white larvae are from the Scymnus sp. ladybugs, which are small, dusky brown ladybugs that have orange heads (rather, the front part is orange) and rear ends. They are the ones that love feeding on aphids and mealybugs, and I’m always happy to see them here. That just means that I’ve got automatic pest control that’s not chemically harmful to the creatures living here!
I wish they had made their way to the nearby watermelon plants, though, because the plants are in a miserable state right now.
