Citrus peelminer larvae are beginning to appear in pummelos
Degree days indicate that the 3rd flight of citrus peelminer will occur the last week of June. The Lindcove entomology crew has been monitoring pummelos this week and found a few small mines confirming that the 3rd flight is starting. If you have pummelo or grapefruit varieties that have had infestations of citrus peelminer, you should treat now to prevent moths from depositing eggs and/or eggs from hatching into larvae.
