I have found that aphids will appear to favor certain pepper plants over others, leaving some almost untouched. They are however, nothing to be ignored in the very least if your plants are young and indoors. Outdoor grows seem to not be affected as much due to rain, hose watering and predatory insects. Indoor starts are a whole different game, I assure you. I answering your question more specifically, yes. orange habaneros will take some of the brunt of an aphid infestation.
