This suggests to me that it may be some kind of deterrent and warning. The red bodied male grows a pair of long white wax tails. Chemical control should be applied to the crawler (first instar) stage because they lack the outer waxy layer that protects older nymphs and adults and they are more mobile on the plant (Furness 1976). If identification to species is not possible using morphological characteristics, DNA-based identifications can be made. Martin NA. The mealybugs suck the plant’s sap, which is high in sugars and low in other nutrients. malacearum Ferris, Ps. 2013). longispinus latipes Green, Ps. Postharvest Biology and Technology 12: 255-264.
