Pathogenicity of Beauveria bassiana and Metarhizium anisopliae to the tobacco spider mite Tetranychus evansi

et al. 2005

Seventeen isolates of Metarhizium anisopliae (Metschnikoff) Sorokin and two isolates of Beauveria bassiana (Balsamo) Vuillemin were evaluated for their pathogenicity against the tobacco spider mite, Tetranychus evansi Baker & Pritchard. In the laboratory all the fungal isolates were pathogenic to the adult female mites, causing mortality between 22.1 and 82.6%. Isolates causing more than 70% mortality were subjected to dose-response mortality bioassays. The lethal concentration causing 50% mortality (LC5o) values ranged between 0.7 x 10(7) and 2.5 x 10(7) conidia ml(-1). The lethal time to 50% mortality (LT50) values of the most active isolates of B. bassiana and M. anisopliae strains varied between 4.6 and 5.8 days. Potted tomato plants were artificially infested with T. evansi and treated with B. bassiana isolate GPK and M. anisopliae isolate ICIPE78. Both fungal isolates reduced the population density of mites as compared to untreated controls. However, conidia formulated in oil outperformed the ones formulated in water. This study demonstrates the prospects of pathogenic fungi for the management of T. evansi.

“…Positive response to root exudates by M. anisopliae was also suggested by Klingen et al (2002). Different isolates of the same entomopathogenic fungus can have varying pathogenicity for a particular pest (Poprawski et al 1985;Bruck 2004) as well as respond differently to biotic and abiotic conditions. Biological control agents differ fundamentally from chemical agents in that in order to be effective, they must proliferate in the environment they are introduced (Nelson et al 1994).…”

Impact of fungicides on Metarhizium anisopliae in the rhizosphere, bulk soil and in vitro

The entomopathogenic fungus Metarhizium anisopliae (Metchnikoff) Sorokin (Hypocreales: Clavicipitaceae) is registered in the United States and The Netherlands for black vine weevil, Otiorhynchus sulcatus (Coleoptera: Curculionidae) control in container-grown ornamentals. These studies were conducted to determine the compatibility of M. anisopliae (F52) with a wide range of fungicides commonly applied to container-grown ornamentals for the management of soil-borne plant pathogens. The impact of fungicides on spore germination and mycelial growth were determined in vitro. In addition, M. anisopliae persistence in bulk and rhizosphere soil was determined 30 days following dual application of each fungicide at 7-28 days intervals as prescribed. A number of fungicides (thiophanate-methyl, dimethomorph, captan, triflumizole, triflozystrobin, pyraclostrobin, azoxystrobin) inhibited spore germination in vitro. A larger number of fungicides (fosetyl-AI, thiophanate-methyl, dimethomorph, captan, quintozene, triflumizole, fludioxanil, triflozystrobin, pyraclostrobin, fludiox-mefanox, iprodione, azoxystrobin, phosphorus acid/K-salts) inhibited mycelial growth in vitro. Only three fungicides (etridiazole, propamocard and mafanoxam) had no significant impact in vitro on spore germination or mycelial growth. While a number of fungicides had a detrimental impact in vitro, there was no impact on M. anisopliae populations in bulk soil following dual application of any fungicide. However, the fungicides captan and triflumizolet, which have a short reapplication interval, had a detrimental impact on M. anisopliae populations in the rhizosphere. As researchers develop rhizosphere competence as an alternative management strategy for black vine weevil, the fungicides captan and triflumizole should be avoided.

“…Ainsi, pour lutter contre les curculionides en zone tempérée, Doberski (1981 ) et Soares et al (1983) ont sélectionné des isolats fongiques dont l'activité pathogène se maintient à des températures inférieures à 15°C . À l'opposé, Ignoffo et al (1976a) et Mohammed et al (1977) ont étudié l'effet des tempéra-tures supérieures à 25 °C sur diverses souches de Nomuraea rileyi (Farlow) Samson inféodées aux noctuelles de l'agroécosystème soja dans le Sud-Est des États-Unis d'Amérique (Ignoffo et al, 1976b;Ignoffo, 1981 (Fargues, 1972;1976), divers Scarabaeidae (Ferron, 1967;Ferron et al, 1972;Fargues et al, 1976), des Curculionidae (Soares et al, 1983;Poprawski et al, 1985), Plutella maculipennis Curtis (Hyponomeutidae) (Robert et Marchal, 1980) ou Ostrinia nubilalis Hübner (Pyralidae) (Riba et al, 1983 (Roberts et Campbell, 1977;Hall et Papierok, 1982;Ferron et al, 1991 (Roberts et Campbell, 1977;Hall et Papierok, 1982 (Ignoffo et al, 1976a;Kish et Allen, 1978). En dehors de quelques exceptions (Fargues, 1972; Fargues et Rodriguez-Rueda, 1980;Maniania et Fargues, 1992) la plupart des travaux ont aussi souligné la concordance entre l'optimum thermique de l'activité végétative du champignon et celui de l'infection fongique sur l'insecte hôte (Hall et Papierok, 1982;Ferron, 1985 (Heinrich, 1981).…”
