Neodusmetia sangwani is an encyrtid parasitoid from India that was used in classical biological control of the Rhodesgrass Scale, Antonina graminis (Maskell) (Pseudococcidae) which is a major pest of grasses outside of its native range in Asia.
In the two days lifespan, females lay about 6 eggs inside about 5 host scales.
Dean and others estimated that the parasitoid saved $17 million in turf management per year and would have boosted cattle production by an estimated $177 million per year.
The scale affected area was about 155,400 km2 which made it necessary to accelerate spread by air-dropping grass sprigs with parasites in cardboard boxes at about 1 per 0.25 square mile.
The total cost of introducing the parasite by the Texas Agricultural Experiment Station at Weslaco was estimated at under $200,000.
