“…Beauveria bassiana is a pathogenic insect fungus that occurs in the soil, which can be used as a biopesticide in the management of crop pests. Fungal survival and infection potential are influenced by the soil pH, the insect cuticle and its hemocoel (Padmavathi et al, 2003). Pathogen-based biopesticides also can be used to control pests.…”

Biopesticides are living organisms or natural products that control agricultural pests including bacteria, fungi, weeds, viruses and insects. Biopesticides can be classified into different categories, such as microbial pesticides, plant-incorporated protectants and biochemicals. Biopesticides are a crucial component of integrated pest management programs for pest control, which lead to more natural alternatives to chemical pesticides that are eco-friendly and safer. Since the emergence of biopesticides for potential pest management, numerous products have been released and some of them dominate the market. This review paper will discuss the current status, future prospect and challenges associated with the use of biopesticides in pest control.

“…During the fermentation process the pH value was not regulated due to the fact that fluctuating pH values between 4.0 and 6.5 have no considerable impact on the growth of B. bassiana (Padmavathi et al [2003]; Thomas et al [1987]). The typical limitation of oxygen can be prevented by increase of the stirrer speed or agitation rate (Patel et al [2011]).…”

Screening of liquid media and fermentation of an endophytic Beauveria bassiana strain in a bioreactor

A novel approach for biological control of insect pests could be the use of the endophytic entomopathogenic Beauveria bassiana isolate ATP-02. For the utilization of the endophyte as a commercial biocontrol agent, the fungus has to be mass-produced. B. bassiana was raised in shake flask cultures to produce high concentrations of total spores (TS), which include blastospores (BS) and submerged conidiospores (SCS). The highest concentration of 1.33×109 TS/mL and the highest yield of 5.32×1010 TS/g sucrose was obtained in the TKI broth with 5% sugar beet molasses which consists of 50% sucrose as a carbon source. In spite of the lower sugar concentration (2.5%) the amount of TS could be increased up to 11-times in contrast to the cultivation with 5% sucrose. The scale-up to a 2 L stirred tank reactor was carried out at 25°C, 200–600 rpm and 1 vvm at pH 5.5. A TS yield of 5.2×1010 TS/g sucrose corresponding to a SCS yield of 0.2×1010 SCS/g sucrose was obtained after 216 h. With regards to the culture medium the cost of 1012 TS amounts to 0.24 €. Plutella xylostella larvae, which were fed with oilseed rape leaves treated with spores from fermentation resulted in 77 ± 5% mortality. Moreover, spores from submerged cultivation were able to colonize oilseed rape leaves via leaf application. This is the first report of fermentation of an endophytic B. bassiana strain in a low-cost culture medium to very high yields of TS.

“…Phenotypic characters in different colony surfaces covered isolate Bb3 and Bb16 isolates with curved shape; Bb6 and Bb2 which were raised, flat or bowl-shaped. Phenotypic characters in colony morphology of isolate B. bassiana were classified into two colonies: dusty and chalky colony (Padmavathi et al, 2003).…”

“…Dusty colony represented higher growth rate of colony (mm/day) than the chalky one (Padmavathi et al, 2003). The curved character colony of isolate (Bb3 and Bb16) had higher growth rate of colony than raised and bowlshaped character (isolate Bb2).…”

“…Selection of fungus isolate according to phenotypic character in colony morphology is easier and more affordable compared with that of biological and molecular characters. Various isolates of B. bassiana indicate that phenotypic character in colony morphology is correlated to virulence isolates (Padmavathi et al, 2003;Cheng-Shu et al, 2002).…”

The research aimed to isolate entomo-pathogenic fungus B. bassiana and describe phenotypic characters in colony morphology as well as measure the growth rate from several natural habitats such as the leaf surface, soil and including larval insect Spodoptera litura and Helicoverpa armigera. The research was done in Kepanjen, Malang from July to October 2000. Purposive random sampling method was used for data gathering. The result showed that B. bassiana isolate managed to be isolated from the three natural habitats involving larva S. litura and H. armigera, the soil, and surface of tomato leaves. B bassiana isolate of insect habitat represented phenotype in colony morphology with curved character, while isolate of the leaves surface and soil indicated phenotype in colony morphology with raised and bowl-shaped character. Isolate of insect with curved colony character represented higher growth rate than that of the leaves surface or the soil with raised and bowl-shaped colony character. Thus, B. bassiana isolate with the curved colony of insect served as an isolate which was expected to be virulent as controlling agent to biological elements. This reseach approve that curve phenotype character in colony morphology can be used as virulence estimation in B. bassiana.
