“…Diadromus species are primary prepupal and pupal parasitoids of DBM in various regions of the world including England (Hardy 1938), Holland (Lloyd 1940), Canada (Harcourt 1960;Anonymous 1996;Braun et al 2004), Australia (Goodwin 1979), Moldavia (Mustata 1992), South Africa (Kfir 1997(Kfir , 1998Kirk et al 2004), China , India (Chauhan & Sharma 2004), France, Turkey, Bulgaria, Georgia and Greece .…”

“…This crucifer specialist may have its origin in Europe (Hardy 1938), but on the basis of the presence of its biocontrol agents (14 species of parasitoids) and host plants (175 species, of which 32 are exotic), Kfir (1998) speculated that it originated in South Africa. Using similar arguments, are of the view that P. xylostella originated in China.…”

The diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), is one of the most destructive cosmopolitan insect pests of brassicaceous crops. 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. In certain parts of the world, economical production of crucifers has become almost impossible due to insecticidal control failures. Consequently, increased efforts worldwide have been undertaken to develop integrated pest management (IPM) programs, principally based on manipulation of its natural enemies. Although over 130 parasitoid species are known to attack various life stages of DBM, most control worldwide is achieved by relatively few hymenopteran species belonging to the ichneumonid genera Diadegma and Diadromus , the braconid genera Microplitis and Cotesia , and the eulophid genus Oomyzus . DBM populations native to different regions have genetic and biological differences, and specific parasitoid strains may be associated with the specific DBM strains. Therefore, accurate identification based on genetic studies of both host and parasitoid is of crucial importance to attaining successful control of DBM through inoculative or inundative releases. Although parasitoids of DBM larvae and pupae are currently its principal regulators, bacteria-derived products (e.g., crystal toxins from Bacillus thuringiensis ) and myco-insecticides principally based on Zoophthora radicans and Beauveria bassiana are increasingly being applied or investigated for biological control. Viruses, nematodes and microsporidia also have potential as biopesticides for DBM. When an insect pest is exposed to more than one mortality factor, there is the possibility of interactions that can enhance, limit, or limit and enhance the various aspects of effectiveness of a particular control tactic. This paper reviews the effectiveness of various parasitoids and entomopathogens against DBM, interactions among them, and their possible integration into modern IPM programs.

“…This approach was employed in tfie vegetable growing areas of South East Asian countries where P. xylostella parasitoids were imported and successfully integrated into the management strategies for this pest (Sastrosiswojo & Sastrodihardjo, 1986). A similar approach can be adopted in South Africa but in this case it may not be necessary to import paras ito ids as there already is a wide range of naturally-occurring P. xylostella parasitoids (Kfir, 1997(Kfir, , 1998. A study carried out in the Northwest Province of South Africa (Kfir, .1997) showed that the most abundant parasitoid in the area was the larval endoparasitoid Cotesia plutellae Kurdjumov (Hymenoptera: Braconidae).…”

“…This requires information about the local resources especially the wild ·host-plants capable of sustaining viable populations of P. xylostella and its pa~asitoids. It has been suggested that in South Africa, there are 175 wild cruciferous species which can serve as alternate hosts of P. xylostella (Kfir, 1998). Currently, there is insufficient information about the preferred non-cultivated host-plants of P. xylostella.…”

Experiments were conducted in plantings of cabbage in spring 1999 and 2000 to evaluate a novel, new matrix system for delivering sex pheromone to suppress sexual communication by diamondback moth, Plutella xylostella (L.). The liquid, viscous, slow-release formulation contained a combination of diamondback moth pheromone, a blend of Z-11-hexadecenyl acetate, 27%:Z-11-hexadecen-1-ol, 1%:Z-11-tetradecen-1-ol, 9%:Z-11-hexadecenal, 63%, and the insecticide permethrin (0.16% and 6% w/w of total formulated material, respectively). Field trapping experiments showed that the lure-toxicant combination was highly attractive to male moths for at least four weeks using as little as a 0.05 g droplet of formulated material per trap; and the permethrin insecticide had no apparent influence on response of moths to lure baited traps. Small field plots of cabbage were treated with the lure-toxicant-matrix combination using droplets of 0.44 and 0.05 g each applied to cabbage in a grid pattern at densities ranging from 990 to 4396 droplets/ha to evaluate the potential for disrupting sexual communication of diamondback moth. There was no significant difference in the level of suppression of sexual communication of diamondback moth, as measured by captures of males in pheromone-baited traps located in the treated plots, versus moths captured in untreated control plots, among the treatments regardless of droplet size (0.05 or 0.44 g) or number of droplets applied per ha. Plots treated with the smallest droplet size (0.05 g) and with the fewest number of droplets per ha (990) suppressed captures of male diamondback moths > 90% for up to 3 weeks post treatment. Although laboratory assays showed that the lure-toxicant combination was 100% effective at killing the diamondback moth, the mode of action in the field trials was not determined. The results indicate that the liquid, viscous, slow release formulation containing diamondback moth pheromone could be used to effectively suppress sexual communication of this pest in cabbage and other crucifers, although as many as three applications probably would be required for suppression over an entire growing season.
