Crawlers of the summer generation are starting to hatch. We found 15 ovisacs: crawlers were hatching from 3 of these, but not from the other 12 ovisacs.
These are the very early stages of egg hatch. The hatched crawlers were still located under the bark. We did not find any GMB activity on the leaves or in the clusters. Eventually, nymphs of the summer generation will move to the fruit and foliage to feed.
Once the nymphs move to the fruit and foliage, this will be the appropriate timing for a contact or IGR insecticide application targeting the summer generation. Systemic insecticides should have already been applied for this generation.
We are seeing increasing evidence of activity of natural enemies: both predators and parasitic wasps. We found larvae, pupae, and an adult of the mealybug destroyer beetle (Scymnus). Unwarranted insecticide applications should be avoided to minimize disruption of natural enemy populations.
