I have a lemon tree in a pot and today I saw after I watered the tree, some insects in the soil. Maybe someone can recognize these insects? Here you can find more photos: http://www.mediafire.com/folder/e5wwcwgn5x5aj/Citrus_Tree_in_Pot_-_Unidentified_Insects_in_Soil
Lemon Tree – Unidentified Insects in Soil!?
Yes, those could be springtail nymphs. The good news is that they don't damage crops. http://ipm.ucanr.edu/PMG/PESTNOTES/pn74136.html
Yes, I know that the picture is blurry, but I can not make a clearer picture because the camera is not meant to make clear shots for this insects so small. I used a 20X magnifying glass but I need a microscope camera for these insects that are very small. Regarding these insects, I think they are springtails!?, but who has more experience can confirm. Thank You!
The picture was blurry when I enlarged it so I can't tell for sure. It looks like either a white aphid or mealybug. If mealybug seems correct (aphid is more likely), look for ladybug larvae before reaching for a pesticide. Ladybug larvae eat mealybugs and the two are not easy to tell apart.
