Relative susceptibility of Spodoptera litura pupae to selected entomopathogenic fungi

Biopesticidal Formulation Of Beauveria Bassiana Effective Against Larvae Of Helicoverpa Armigera.

“…Among the three different formulations, it was found that the bentonite based liquid formulation had the highest efficacy. Anand et al [1] has reported that the fungal pathogen Beauveria bassiana infects pupae of Spodoptera litura in a dose-dependent manner for each of the formulations investigated which corroborates the findings of the present investigation. They also reported that Beauveria bassiana was more infective and resulted in maximum average percent mortality among the three species viz.…”

“…The larvae collected 25 days after treatment developed infection in a maximum period of 32 days after collection from the field. This was in accordance with the field bioassay of Anand et al [1].…”

“…In recent years, crop protection based on biological control of crop pests with microbial pathogens like virus, bacteria, fungi and nematodes has been recognized as a valuable tool in pest management [1,2]. The appropriate use of eco friendly microbial biopesticide can be engaged in recreation of sustainable organic crop production by providing a stable pest management program.…”

Differential pathogenicity of Metarhizium anisopliae and the control of the sugarcane root spittlebug Mahanarva fimbriolata

“…Additional benefits of using this particular pathogen are that it is also active against the borer Diatraea saccharalis (Fabricius) but does not affect some of the natural enemies of the spittlebug such as the wasp Salpingogaster nigra (Schiner) and predator ant Pheidole genalis (Borgmeier) (Mendonça and Mendonça, 2005). Several studies have been conducted that focus on the isolation and screening of entomopathogenic fungi which may be effective in controlling the pest insects (Entz et al, 2008;Anand et al, 2009). For example, the pathogenicity of isolates of M. anisopliae from different hosts and regions of Brazil have been tested against the spittlebug M. fimbriolata (Loureiro et al, 2005;Macedo et al, 2006).…”

Efficacy of Beuveria bassiana on Different Larval Instars of Tobacco Caterpillar (Spodoptera litura Fab.)

“…It is one of the most destructive pest of cauliflower, groundnut, cotton, tomato, cabbage and other cruciferous crops (Anand et al, 2009). It passes through 5-6 overlapping generations annually (Sasidharan and Varma, 2005;Kumar and Chapman, 1984) and if not controlled timely, it may result in huge crop losses ranging from 25.8-100 per cent in various parts of India (Ahmad et al, 2005).…”
