There is an urgent need to develop biological control methods against the eriophyoid mite, Phyllocoptes gracilis, which causes significant losses in organic raspberry production in Europe. The use of entomopathogenic fungi (EF) is a sustainable alternative to conventional chemical pesticides, reducing the risks of pesticide resistance and other negative environmental impacts of agriculture. The objective of this study was to assess the pathogenicity of three strains of EF, two of Beauveria bassiana and one of Metarhizium anisopliae, on P. gracilis under laboratory conditions. Fungal spore suspensions (1 × 107 spores per mL) were sprayed on detached leaves infested with P. gracilis. Treated mites were kept under controlled conditions (25 ± 3 °C, 72 ± 10% relative humidity and photoperiod of 16:8 (light/dark)) and mite mortality was assessed three, five and seven days after inoculation. At all three measurement points (days after inoculation), the mortality of P. gracilis was highest for B. bassiana strain BB 1.1 and M. anisopliae strain MA 10.1. Our data demonstrate that EFs are promising candidates for the development of biological control agents against P. gracilis in raspberry crops.

“…In the present study fungal pathogens that parasitize mites are valuable tools for biological control and play an important role in encouraging integrated pest management. Till date, H. thompsonii has been used to manage mites (Yadav Babu, 2004;Aghajanzadeh et al, 2006;Fernando et al,2007).…”

Efficacy of fungal pathogens, Fusarium semitectum Berk. and Ravenel and Hirsutella thompsonii Fisher was evaluated against red spider mite, Tetranychus neocaledonicus (Andre) of okra under laboratory and greenhouse conditions. Among the treatments evaluated under laboratory conditions, the highest mortality of 78.20 and 88.34 percent adults and immatures, respectively was recorded at 2.10 x 109 spores per ml of F. semitectum, whereas it was 82.05 and 92.31 per cent adults and immatures, respectively in case of H. thompsonii at 4.60 x 108 spores per ml. Among the twelve treatments evaluated under greenhouse conditions, H. thompsonii 4.60 x 108 spores per ml, F. semitectum 2.10 x 109 spores per ml + H. thompsonii 4.60 x 108 spores per ml, H. thompsonii 4.60 x 108 spores per ml + dicofol 0.025% and F. semitectum 2.10 x 109 spores per ml + H. thompsonii 4.60 x 108 spores per ml + dicofol 0.025% were found to be on par with each other with a cumulative percent mortality of 81.20, 81.48, 81.21 and 82.59 percent, respectively. By testing the field efficacy of F. semitectum and H. thompsonii against T. neocaledonicus, these fungal pathogens can be used as potential biocontrol agents for the sustainable management of mites on okra. Hence the present study evaluates the potentiality of F. semitectum for the management of T. neocaledonicus by comparing with the well-known acaricidal fungus, H. thompsonii.
