“…The entomopathogenic hyphomycetes are known to be mesophilic since most of the isolates tested so far grow over a range of 8 to 30-32°C, with thermal optima ranging from 20 to 30°C, and limits at <5 and >35°C (Ferron et al, 1991;Fargues et al, 1992;Masuda and Kikuchi, 1992;Mietkiewski et al, 1994;Vidal et al, 1997a). In the present study, we have shown that thermal tolerance of the two isolates Pfr11 and Pfr46 were related to their history, including the geo-climatic origin.…”

“…Pathotypes were morphologically associated with sclerotium density and defoliating/non-defoliating type but unrelated to geographic origins. The results of this study provide no evidence to support a clear relationship between pathogenicity and a number of traits, e.g., ger mination rate, spore size, and sporulation ability of some Verticillium spp, as suggested by Hall (1984) and Masuda and Kikuchi (1992).…”

ABSTRACT. Verticillium dahliae is a fungal pathogen that causes wilt disease in a wide range of host plants. Charac terization of virulence, morphological, and molecular variations among V. dahliae isolates from different geographic origins is essential for any breeding program aimed at producing plant cultivars resistant to this disease. We characterized virulence variation among V. dahliae isolates from Chinese cultivated eggplant grown in Northeast China by pathogenicity testing on susceptible, moderately resistant, and resistant eggplant accessions in a glasshouse using a root-dipping method of infection. These isolates were also characterized for morphological features based on growth on potato dextrose agar media and for genetic variation based on ISSR markers. All 12 isolates were divided into three pathotypes based on the virulence, i.e., strong, moderate, or weak type. Three isolates were categorized as defoliating pathotypes, with strong virulence, and the rest of the isolates were categorized as non-defoliating pathotypes, with moderate to weak virulence. The eggplant isolates were classified into three morphological types or morphotypes, hypha, hypha-sclerotia, and sclerotia; no significant correlations were detected between pathotypes and morphotypes or geographic origins. ISSR fingerprinting indicated genetic diversity among isolates, ranging from 0.26 to 0.69. Specific fingerprint types were not correlated with either pathotype or morphotype. However, ISSR analyses did reveal two clusters in which the isolates in each share the same or neighboring geographic origins.

“…All these laboratory and greenhouse experiments led to the development of two commercial products "Vertalec" and "Mycotal" based on strains specifically selected for use against aphids and whiteflies (Gardner et al, 1984;Ramakers, 1989). V. lecanii has been tested experimentally against a range of pests, in a number of countries, with varying results which were said in general to be encouraging (Kitazawa et al, 1984;Helyer & Wardlow, 1987;Saito, 1988;Gour & Dabi, 1988;Gopalokrishnan, 1989;Ravensberg et al, 1990a;Ravensberg et al, 1990 b;Byrne, 1991;Van der Schaaf et al, 1991;Meade & Byrne, 1991;Masuda & Kikuchi, 1992;Pinna, 1992;Chandler et al, 1993;Zukauskiene & Sirvinskas, 1993;Helyer, 1993;Ravensberg et al 1994;Miranpuri and Khachatourians, 1994;Fournier, 2000;Gindin et al, 2000;Wang et al, 2004;Nirmala et al, 2006;Liande et al, 2007;Jeong et al, 2007;Van et al, 2007;Goettel et al, 2008;Jeong et al, 2008;Chavan et al, 2008;Shinya et al, 2008).…”

Chemical insecticides play an important role in the control of plant damage and plant diseases. However, extensive use of these products has led to the disruption of ecosystems because of several reasons such as death of non-target species, accumulation of pesticide residues in the environment and food, and buildup of pesticide resistance in the target species. Biological control is one of the alternatives to chemical pesticides and it can be described as the limitation of the abundance of living organisms and their products by other living organisms. Predators, parasitoids, fungi and other beneficial organisms can be used for the biocontrol of insect pests. The fungus Verticillium lecanii is one of the members of Deuteromycetes and it can be used for crop protection. This paper is a review of the international literature related to V. lecanii for the bio-control of insects of agricultural importance.
