It has been introduced to several countries or regions and has established as a successful biocontrol.
Biological control of diamondback moth . Another common symptom is the defoliation of the plant. DBM has been estimated globally to cost US$ 1 billion in direct losses and control costs. It was the first crop insect reported to be resistant to DDT and now, in many crucifer producing regions, it has shown significant resistance to almost every synthetic insecticide applied in the field. The diamondback moth is a global pest. Box 12301, 50774 Kuala Lumpur Status of DBM and other pests of crucifers and their biocontrol 71 Classical biological control of diamondback moth: the Malaysian experience Syed, A.R. Diamondback moth larvae can eat the head, which can lead to making it unattractive and worse, unmarketable. Loke 2 & I. Fauziah 1MARDI Cameron Highlands, 39007 Tanah Rata Cameron Highlands, Pahang 2 Strategic, Environment and Natural Resources Center, MARDI,G.P.O. In Talekar, N.S., and Griggs T. D. The rate of infection of diamondback moth larvae can be high enough to limit the development of additional generations late in the season.
Abstract. In Queensland the most significant of these is Diadegma semiclausum , a small, black, 7 mm long wasp which lays its eggs into young DBM caterpillars. The use of parasites in the biological control of the yponomeutid Plutella xylostella, a pest of crucifers, is reviewed, and attempts to import parasites and release them in various countries are critically examined.
Many glucosinolates stimulate feeding in diamondback moths… The diamondback moth (DBM), Plutella xylostella (L.), remains a major pest of brassica crops worldwide.
Biological control of the diamondback moth, Plutella xylostella: A review. The host range of diamondback moths is limited to crucifers that contain mustard oils and their glucosides (60, 61, 71, 113, 181, 182). Chemical control of this pest remains difficult due to the rapid development of resistance to insecticides and to their effect on natural enemies. Abstract The diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), is one of the most destructive cosmopolitan insect pests of brassicaceous crops.
Despite the abundance of potential biological control agents, the only effective way of controlling a diamondback moth outbreak once the population exceeds the economic threshold is to apply an insecticide.

In Queensland the most significant of these is Diadegma semiclausum, a small, black, 7 mm long wasp which lays its eggs into young DBM caterpillars. Biological control A range of predators and parasitoids attack DBM and can give good control of the pest in mild weather. Biological Control of Diamondback Pacific D.F. Loke 2 & I.
