“…In contrast, Fargues & Robert (1978) demonstrated pathogenicity changes of two pathotypes of M. anisopliae after subculture or passage. Other studies (Ganhao, 1956;Hartmann & Wasti, 1974;Krejzova, 1975Krejzova, , 1977Nagaich, 1973;Wasti & Hartmann, 1975;Timonin et al 1980) also suggest that infectivity is changed following subculture or passage but these authors did not use sensitive bioassay systems to determine infectivity.…”

SUMMARYThere are many species of fungi attacking terrestrial and aquatic insects of agricultural and medical importance. Of these, few species have received much attention with a view to their use as biological control agents. The mechanisms of infection have been comparatively well studied, although many questions remain to be answered. The knowledge so far obtained has shed some light on the reasons for host specificity. Temperature, above all relative humidity, and their interactions are the most important physical factors influencing infection of terrestrial insects by entomopathogenic fungi and these are discussed in relation to epizootiological events. In aquatic environments, temperature, salinity and organic pollution are the important factors. In addition to these physical factors, numerous biotic factors at the level of the insect and the fungal pathogen influence both infection and spread of disease in insect populations. The complexity of the interactions of the biotic and abiotic factors makes it extremely difficult to study the influence of any one of these. Virulence of fungal pathogens and its measurement are discussed, together with the shortcomings of present bioassay systems; virtually no laboratory bioassay system exists which has been designed to yield data meaningful in the field. Mass-production techniques are described as are their inherent problems and those of formulation and storage. Finally, the achievements of fungal control of insects in the field are reviewed. Thus far, several species are mass-produced and are in widespread use, two of which,Verticillium lecaniiandHirsutella thompsonii, have been commercialized. More studies, ecological, fundamental and developmental are required in this field to realize fully the potential of other candidate fungi.

“…Fogal et al (1986) described a simple mass production technique for M anisopliae using wheat bran as the carrier medium. Number of carrier cum growth media such as wheat bran, (Fogal et ai, 1986, Timonin et al, 1980 sorghum grains, boiled rice grains, coffee husk, coconut water, etc. have been used for their efficacy in promoting the growth and sporulation of Manisopliae.…”

Indeed, third instar C. rosaceana were found to be susceptible to 23 isolates of B. bassiana in laboratory trials (Todorova, Coderre, Vincent, & Côté 2002) in which larvae were dipped in conidia suspensions and placed on meridic diet.…”

The susceptibility of immature Choristoneura rosaceana (Harris) to Beauveria bassiana-GHA (BotaniGard † 22WP) was evaluated under laboratory and field conditions. Although egg masses 524 h old were susceptible to infection by topically sprayed B. bassiana spores in the laboratory and resulting mycosis significantly reduced the percent of neonates able to emerge, no significant egg mass infections resulted from orchard treatment of 524Á48 h eggs. Exposure to high levels of the B. bassiana product on apple leaf surfaces in the laboratory caused significant dose-related mortality in first to fourth instar C. rosaceana. First instar C. rosaceana were the most susceptible of the larval stages assayed in the laboratory although only 36% of neonates introduced into the orchard prior to Beauveria treatment and 27% of the neonates emerging from orchard treated egg masses became infected. Fourth instar mortalities were similar but moderate when treated with 1)10 8 spores mL (1 in the orchard and on leaf surfaces in the laboratory. Beauveria bassiana-induced larval mortalities were significantly higher when the spores were applied directly to the larval integument as opposed to the leaf surface where the insect would encounter the pathogen in a treated orchard. Feeding of C. rosaceana larvae on antibiotic containing meridic diet prior to their use in trials did not impact the susceptibility of the larvae to B. bassiana. Antibiotic containing meridic diet significantly reduced larval C. rosaceana mortality when treated larvae or the spores were placed directly on the diet as opposed to leaf tissue.
