dc.descriptionBiological control is proving effective against two pests that have been major problems in Fiji, rhinoceros coconut beetle (Oryctes rhinoceros) in coconut and diamond-back moth (Plutella xylostella) in cruciferous crops, in particular European cabbage. A combination of viral and fungal pathogens, together with changes in management, has reduced rhinoceros beetle numbers and the damage they cause very significantly. A new approach to bio-control against diamond-back moth is showing better results than earlier attempts, when the release of predators and pathogens was prejdiced by continuing use of broad spectrum insecticides. Most recently, two hymenopterous predators of P. xylostella have been released, Cotesia plutellae and Diadegma eucerophiagi, and insecticides specific to Lepidoptera have been used: Dipel, a bacteria-based product, and Atabron, a chitin inhibitor. The latest control regime has resulted in the need for spraying against diamond-back moth being reduced from 8-12 times during the growth period of cabbage to 2-3 times. Farmers are very satisfied because of the saving in costs of chemicals and spray applications, while consumers are benefiting from reduced risk of pesticide contamination in fresh vegetables.
