“…Outbreaks of DBM in Southeast Asia sometimes cause crop losses of more than 90% (Verkerk & Wright 1996). It is a very destructive pest in southern Sind (Hyderabad and Karachi region) of Pakistan where cruciferous vegetables are grown throughout the year and due to its severe infestations, growers are sometimes compelled to plough down their standing crops in spite of multiple insecticide applications (Abro et al 1994).…”

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.

“…For example, major Southeast Asian outbreaks of P. xylostella sometimes cause crop losses exceeding 90% (Verkerk and Wright, 1996). Control failures caused by widespread insecticide resistance in this pest have stimulated great interest in integrated pest management (IPM) of P. xylostella (Potting et al, 1999).…”

The influence of food supply on the survival and oviposition ability of Cotesia plutellae, the larval parasitoid of the diamondback moth, Plutella xylostella, was examined in the laboratory. The longevity of the parasitoid decreased drastically under a lack of sugar availability. The oviposition ability, evaluated by functional response to host density, was highly suppressed by a lack of food supply. Thus, sugar availability is a very important condition for the effective utilization of C. plutellae as a biological control agent of P. xylostella in greenhouses.

“…Plutella xylostella (L.) (Lepidoptera, Plutellidae). The Diamondback moth (DBM) constitute an important threat for this food supply because it can cause yield losses higher than 90% (Verkerk and Wright, 1996;Mondédji, 2010). This insect species is a problem in the tropical and subtropical countries where cabbage is grown all year round.…”

Conservation biological control, which fosters the optimal use of indigenous natural enemies, is a promising way for reducing pesticide reliance in horticultural systems. The objective of this study is to determine the distribution of parasitoid species, their parasitism rates on pest populations in relation to environmental conditions in the main Senegalese market garden area (Niayes). To do this, one hundred and sixteen cabbage plots, distributed in the Niaye segmented into three areas, along a South-North transect, are chosen. These plots were observed during four crop seasons from October 2012 to May 2014. Pest larvae were counted every three weeks using 24 randomly chosen cabbage plants per plot. Four hymenopteran parasitoid species were identified; Oomyzus sololowskii (Kurdjumov), (Eulophidae), Brachymeria sp. (Chalcididae), Apanteles litae Nixon and Cotesia vestalis (Haliday) both Braconidae. The percentage of parasitism varied between the plots, the geographical locations and the sampling period. O. sokolowskii and A. litae species were predominant and were affected by the growing season. The species distribution in the three sampling areas revealed that O. Sokolowskii was more efficient during the cold dry season, whereas A. litae was more efficient during the hot dry season. These results aim at identifying conditions favorable to the regulation of populations of cabbage moth by natural enemies. Parasitoids can play a promising role as biological control agents in Senegal. In order to do this, studies such as these must be carried out and the results communicated to farmers who often misunderstand the primordial role that natural enemies can play in pest control.
