Notes: [Conference: Management Strategies for the Control of the Hibiscus Mealybug. Centeno (Trinidad and Tobago). 12 Apr 1998.] Studies conducted on cost of production of the Australian ladybird, Cryptolaemus montrouzieri Mulsant, and the Indian ladybird, Scymnus coccivora Aiyar, fed on hibiscus mealybug, Maconellicoccus hirsutus (Green) revealed that the predators could be successfully mass-produced and the rearing protocols of these predators are discussed. The use of 2 percent bleach solution for sterilization of glassware and buckets and the dusting of sulphur helped in reducing mite contamination. Seventy percent alcohol, petroleum jelly and soapy water were used to contain the high population of high population of Hibiscus Mealybug existing in the laboratory. Finally, kerosene was used in the daily incineration of all waste material removed after routine maintenance of the lab cultures.
