“…Boulenouar et al [23] also observed that the different strains of the same bacteria may show different growth and toxic activities, which may be due to the differences in growth requirements of different strains. In the past, many attempts have been made to culture Bacillus to produce toxin at cheaper cost which has provided similar mosquito toxicity as observed in the present study [24–26]. …”

Production of indigenous isolate Bacillus thuringiensis sv2 (Bt sv2) was checked on conventional and nonconventional carbon and nitrogen sources in shake flasks. The effects on the production of biomass, toxin production, and spore formation capability of mosquito toxic strain were determined. Toxicity differs within the same strain depending on the growth medium. Bt sv2 produced with pigeon pea and soya bean flour were found highly effective with LC50 < 4 ppm against larvae of Aedes aegypti. These results were comparable with bacteria produced from Luria broth as a reference medium. Cost-effective analyses have revealed that production of biopesticide from test media is highly economical. The cost of production of Bt sv2 with soya bean flour was significantly reduced by 23-fold. The use of nonconventional sources has yielded a new knowledge in this area as the process development aspects of biomass production have been neglected as an area of research. These studies are very important from the point of media optimization for economic production of Bacillus thuringiensis based insecticides in mosquito control programmes.

“…Mediums to use can be prepared from organic waste materials available locally (such as liquid manure, rice bran, cotton meal, molasses, and potato starch/dextrose, coffee husks) (Poopathi and Abidha, 2011;Abbasi et al, 2013). A medium should have a proper C:N ratio (optimal between 5-15).…”

ReferaatIn dit rapportage bevat technische advies over massaproductie en de formulering van bacteriële isolaten (Bacillus en Pseudomonas) en entomopathogene schimmels (Beauveria en Metarhizium). Dit advies zal de eindgebruikers in Ethiopië helpen om weloverwogen beslissingen te nemen wat betreft het meeste passende strategieën voor de productie van biologische bestrijders (BCA) op semi-industriële schaal. AbstractIn this report the technical advice in given for mass production and formulation of bacterial isolates (Bacillus and Pseudomonas) and entomopathogenic fungi (Beauveria and Metarhizium). This advice will allow the end users in Ethiopia to make an informed decision about the strategies for the production of biological control agents (BCA's) on semi-industrial scale. The purpose of the production being application to the crops against plant pathogenic Fusarium species and insect pests.

“…Use of such methods would reduce waste treatment costs, prevent environmental pollution, improve the soil condition and yield biologically active re-useable substances. Considering the above applications, there has been an identification recently of several bio-organic waste materials from industries, for the production of biopesticides [96,[99][100][101][102][103]. All the raw material are rich in nutrient sources (carbohydrate and proteins) and lead to production of bacterial biopesticides (Bacillus sphaericus, Bs and B. thuringiensis subspecies P. israelensis, Bti), which are well known biocontrol agents used in mosquito vector control programs [17,51,104].…”

Bacillus sphaericus Neide (B) and B. thuringiensis serovar israelensis (Bti) de Barjac provides effective alternatives to broad spectrum larvicides in many situations, with little or no environmental impact. Taking into account environmental benefits including safety for humans and other non-target organisms, reduction of pesticide residues in the aquatic environment, increased activity of most other natural enemies and increased biodiversity in aquatic ecosystems, their advantages are numerous. In addition to recombinant bacteria used as larvicides, research is also underway to develop transgenic algae and cyanobacteria using larvicidal endotoxins of Bti and Bs. The advent of recombinant DNA technology is now having an enormous impact on agriculture and medicine, and it is appropriate that the ability to manipulate and recombine genes with this technology be applied to improving larvicides for vector control. These new recombinant bacteria are as potent as many synthetic chemical insecticides, yet are much less prone to resistance, as they typically contain a mixture of endotoxins with different modes of action. The existing recombinants also have what can be considered disadvantageous, in that they do not show significantly improved activity against aedine and anopheline mosquitoes, in comparison to Bti. But it may be possible to overcome this limitation using some of the newly discovered mosquitocidal proteins, such as the Mtx proteins and peptides such as the trypsin-modulating oostatic factor, which could be easily engineered for high expression in recombinant bacteria. While other microbial technologies such as recombinant algae and other bacteria are being evaluated, it has yet to be shown that these are as efficacious and environment friendly as Bti and Bs. By combining the genes from a variety of organisms, it should ultimately be possible to design 'smart' bacteria that will seek out and kill larvae of specific vector mosquitoes. Thus, recombinant bacteria show excellent promise for development and use in operational vector control programs, hopefully within the next few years. documented [5,6]. Vector control is recognized as an effective tool for controlling tropical diseases. Several strategies have been adopted to control these dipteran pests, and to reduce vector-borne diseases. Synthetic insecticides have been effectively used during the past several decades for mosquito-control operations. But the chemical approach has several demerits, such as the development of insecticide resistance, environmental pollution, bio-amplification of contamination of food chain, and harmful effects to beneficial insects. Hence, there has been an increased interest in recent years, in the use of biological agents for mosquito control. Bio-Pesticides as Effective Tools for Mosquito Control In recent years, it has been witnessed, an increased interest in the usage of bio-pesticides as effective tool for mosquito control. Several bio-control agents were screened for their potency, mammalian safety and environmental imp...
