Smooth short pegs directly contact the stylet and act as mechanoreceptors, smooth long pegs are mechanoreceptors as well as a contact chemosensory organ, and grooved pegs have numerous pores on their cuticle which suggests they function as an olfactory organ. Phenacoccus manihoti is a scale insect species. The introduction of A. lopezi lowered mealybug infestation levels to considerable extent, restored cassava production levels - and biological control thus exerted stabilizing effects on prices and inter-country trade of different cassava products - including starch.
