If mostly small nymphs are captured in a sticky trap, what does this imply?

The presence of mostly small nymphs captured in a sticky trap strongly implies that there may be a localized pocket of infestation within a short distance. Small nymphs indicate that the population is likely in its early development stages, and capturing them suggests that they are emerging from a nearby source of infestation. This often happens when adults lay eggs in proximity to the trap, and with nymphs being more vulnerable, they are more likely to be caught.

Capturing primarily small nymphs suggests an ongoing reproductive cycle nearby rather than an established adult population or a declining one, which would typically manifest in older life stages. Observing this life stage indicates active growth, thus supporting the notion of a localized issue rather than a larger, more dispersed infestation or the absence of one. This underscores the importance of targeted intervention in that specific area to manage the potential spread before it escalates.
