“…The average sucrose yield achieved in plots treated with the 4ϫ rate of M. anisopliae granules and the signiÞcant linear sucrose yield response in relation to fungus application rate support previous laboratory research that demonstrated the entomopathogenic capability of M. anisopliae accession ATCC 62176 (Jonason et al 2005). Yield differences in this study were not sufÞcient to allow differentiation between placement methods or application timings of the mycoinsecticide.…”

“…Data from Þeld trials indicated that M. anisopliae was capable of reducing root maggot damage under low to moderate root maggot pressure (Campbell et al 2000). In subsequent laboratory testing, Jonason et al (2005) showed that ATCC 62176 was superior to ATCC 22099, several other M. anisopliae strains, and a Beauveria bassiana (Balsamo) Vuillemin isolate. However, information on the impacts of formulation, rate, or application timing on the pest management potential of M. anisopliae and, more speciÞcally ATCC 62176, is lacking.…”

“…In practical use, younger instars of this insect, the primary targets of control measures, are more susceptible to M. anisopliae than the third instar larvae used in these bioassays (Jonason, Boetel, Eide, Campbell, and Rao 2005). Therefore, better biocontrol efficacy by the MS granule would presumably be demonstrated in field use.…”

The entomopathogenic fungus Metarhizium anisopliae has very recently been shown to produce microsclerotia (MS) Á compact, heavily melanised, hyphal aggregates Á in liquid media. Soil incorporation bioassays of dried MS preparations of three isolates of M. anisopliae were conducted using third instar Tetanops myopaeformis (sugarbeet root maggot) in clay and/or clay loam field soils as a model system to demonstrate efficacy. At rates as low as 23 mg MS granules/100 g dry soil, the biocontrol efficacy of MS granules of M. anisopliae Strain F52 produced in liquid media with a high carbon concentration (36 g/L) and high C:N ratios (30:1, 50:1) were superior to MS preparations produced in low carbon (8 g carbon/L) media and a high carbon medium with a 10:1 C:N ratio. Bioassays using MS formulations of M. anisopliae strains MA1200 and TM109 produced in high carbon and high C:N ratio media were superior in efficacy to the other MS production media tested. MS preparations of M. anisopliae F52 showed superior efficacy against the sugarbeet root maggot in comparison with more conventional, conidia-covered nutritive (corn grit) granules in a clay and clay soil. The MS granules were also highly efficacious against the sugarbeet root maggot at soil moisture levels as low as 0.983 A w ( (2.33 MPa). Granular preparations incorporating Metarhizium MS can serve as a viable formulation for the use of this fungus against soil insects.

“…They were tested against red palm weevil Rhynchophorus ferrugineus (Olivier) revealing high mortality rate among larvae reaching 100% after 6-7 days of treatment; moreover, treated eggs expressed lower hatching percentages (Gindin et al, 2006). M. anisopliae expressed high virulence against sugarbeet root maggot larvae as reported by Jonason et al (2005). They were also applied to control brown-winged green bug, Plautia stali Scotto (Hemiptera: Pentatomidae) revealing efficient and successful outcome (Ihara et al, 2001).…”

Virulence of entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana were tested against Arabian Rhinoceros Beetle, Oryctes agamemnon arabicus larvae. Four concentrations (1×105, 1×107, 1×109 and 1×1011 conidia/mL–1) of two locally isolated entomopathogenic fungi spore suspensions were used in this study via larval direct spraying. Results revealed that both isolates can cause high mortality rate reaching 100% after 29 days. However, Beauveria bassiana scored higher mortality rate in short time especially at the concentration of 1×1011 conidia/ mL–1 with lethal time (LT)50 12.75 and LT90 20.00; while, Metarhizium anisopliae caused the higher percentage of malformed adults. Moreover, both isolates affected insect’s life cycle particularly in the pupal stage which was reduced remarkably by almost 50% in comparison with the control treatment.
