Mealybugs are found injurious to tobacco (Nicotiana tabacum) in India, Zimbabwe, Africa, Italy, Argentina, etc. Phenacoccous solenopsis Tinsley has been reported both in the nursery and fields in India. Heavy infestation of Ph. solani has been reported found in Zimbabwe. In the nursery, Phenacoccous solenopsis appears in early sown tobacco nurseries and multiplies in large number and causes damage to young leaf by sucking sap form the succulent leaf. The affected leaf shows puckering symptoms and become brittle in later course of development. The Australian ladybird beetle Cryptolaemus montrouzieri Mulsant at 2–3/- tobacco plant gave good control of Ferrisia virgata in the glass house. On tobacco, methomyl 90.80 % and profenophos had significantly reduced the mealybug population of Ph. solenopsis in Gujarat. In Gujarat, India, the encyrtid Aenasius bambawalei Hayat was found on P. solenopsis up to 30 % parasitism.
