Mani, M., & Krishnamoorthy, A. 2001 Suppression of Maconellicoccus hirsutus (Green) on guava.. Insect Environment 6(4): 152.
Notes: A study on the biological control of the pink mealybug, M. hirsutus, on guava by the Australian ladybird beetle, Cryptolaemus montrouzieri, is presented. The ladybird beetle was released at 20/plant in the first week of June, in 1992, in Bangalore, Karnataka, India. A mean mealybug population of 918.50/plant was observed in the first week of June at the time of releasing the predator. There was a reduction in the mealybug population, a month after the release of the predator, and a mean of 4.60/plant was recorded by the end of August 1992 on the predator-released plants compared to 781.40 on the control plants.
