“…1 and 2). Sheeba et al (2001) applied B. bassiana against S. oryzae and recorded (86.2%) the mortality rate in adults after day 25. In another study, Khashaveh et al (2011) tested the commercial product of B. bassiana against S. granarius, Oryzaephilus surinamensis, and Tribolium castaneum at 24 ± 2°C recording 88.33, 78.31, and 64.99% mortality, respectively.…”

Efficacy of the five native entomopathogenic fungi (EPFs), Beauveria bassiana, Isaria fumosorosea, Lecanicillium muscarium, Metarhizium anisopliae, and Simplicillium lamellicola, against adults of the stored-grain insect pests, Sitophilus granarius and Sitophilus oryzae (Coleoptera: Curculionidae), was evaluated under laboratory conditions at two different temperatures. Conidial suspensions (1 × 10 8 conidia ml −1 ) of the fungi were directly applied to both the pests in Petri dishes (2 ml per dish), using a Potter spray tower. All the dishes were incubated both at 20 and 25°C in 16 h light/8 h dark and in 75 ± 5% relative humidity (RH). Dead individuals were counted daily, following treatments, for 7 days. Lethal time values (LT 50 and LT 90 ) for EPFs were calculated. The results demonstrated that the mortality rates varied according to both the temperature and the tested EPFs. The highest effect among EPFs at (1 × 10 8 conidia ml −1 ) concentration on S. granarius at 20°C at the end of day 7 was showed by I. fumosorosea (92.69%) and M. anisopliae (90.35%), followed by the other EPFs. Similarly, M. anisopliae and I. fumosorosea were the most effective ones with 90.48 and 84.21% mortality rates, respectively, at 25°C. However, while M. anisopliae (85.68%) showed the highest effect among all the EPFs applied on S. oryzae at 20°C, B. bassiana with a mortality rate of 93.66% was the most effective one at 25°C. LT 50 values for I. fumosorosea and M. anisopliae were 2.75 and 2.88/days, respectively, and LT 90 values were 4.17 and 4.47/ days, respectively, at 20°C for S. oryzae. However, LT 50 values for M. anisopliae on S. granarius in both temperatures were the lowest. This study indicated that M. anisopliae and I. fumosorosea had a significant potential as a biological control agent against S. granarius and S. oryzae. Further studies are necessary to evaluate the efficacy of the isolate on the pests under storage conditions.

“…Several Hyphomycetes, such as Beauveria bassiana and Metarhizium anisopliae, offer good potential for mass production on artificial media and have been investigated for use as microbial control agents (Lacey et al, 2001). There have been investigations of the use of entomopathogenic fungi in the control of weevils such as Curculio camelliae (Saito and Suzuki, 1982), the sweet potato weevil, Cylas formicarius (Ohba and Aizawa, 1988), the boll weevil, Anthonomus grandis (Wright and Chandler, 1991), the pea weevil, Sitona lineatus (Verkleij et al, 1992), the ash weevil, Stereonychus fraxini (Markova, 1992), and the rice weevil, Sitophilus oryzae (Sheeba et al, 2001). These studies therefore led us to hypothesize that entomopathogenic fungi might be useful in the control of the chestnut weevil.…”

We used a baiting method to isolate 65 entomopathogenic fungi with pathogenicity to the chestnut weevil larva from soil samples. Metarhizium anisopliae strain HF293 showed the highest pathogenicity. Under laboratory conditions, the LD 50 value of strain HF293 on the 10th day after treatment of newly emerged larvae was 9.9ϫ10 3 conidia/larva, and the mortality rate of larvae reached 56% at five weeks after treatment with a conidial dose of 2.0ϫ10 2 /larva. Susceptibility of the larvae that had been stored at 6°C to strain HF293 gradually decreased over the first three months of storage but stabilized by the fourth month. The results of a field study of larvae in flowerpots indicated that the survival rate of larvae decreased with increasing doses of conidia of M. anisopliae strain HF293.

“…Variations in pathogenicity (virulence) among isolates against stored product insects have been previously reported in assays with B. bassiana and M. anisopliae on S. zeamais (Adane Kassa et al, 1996;Hildago et al, 1998; Adane Kassa, 2003), Sitophilus oryzae (Dal Bello et al, 2001;Sheeba et al, 2001;Padin et al, 2002), Prostophanus truncatus (Miekel et al, 2001; Adane Kassa, 2003), Sitophilus granarius (Athanassiou and Steenberg, 2006), Rhizopertha domonica (Lord, 2001), Caryedon serratus (Ekesi, 2001), Cryptolestes ferrugeneus (Lord, 2001), Oryzophilus surrinamensis (Thorne and Lord, 2004), Plodia interpunclella and Ephestia kuehniella (Bischoff and Reichmuth, 1997).…”

Evaluation of eleven Metarhizium anisopliae and six Beauveria bassiana isolates against the maize weevil Sitophilus zeamais was conducted under laboratory with the objectives of identifying the most virulent locally available fungal isolates, and determining the dose mortality response. The pathogenicity (virulence) of the entomopathogenic fungi was determined using LT 50 and percent mortality at the conidial concentration of 1 x 10 8 ml-1. The most virulent isolates of M. anisopliae (PPRC-2, PPRC-14 and PPRC-51) and B. bassiana (PPRC-GG and PPRC-HH) caused 84.4% to 98.3% mortality to S. zeamais. These isolates had LT 50 ranging from 3.8 to 4.3 days. The dose response study with the isolates PPRC-2, PPRC-14 and PPRC-51 at doses ranging from 1x 10 4 to 1x 10 8 conidia ml-1 revealed susceptibility of the S. zeamais with mortality ranging from 25 to 95.5%. There was an increase in the resulting LT 50 from 4.0 to 11.9 days with a decrease in conidial concentration from 1x 10 8 to 1x 10 4 conidia ml-1. PPRC-2 showed the lowest LC 50 (1.46x 10 conidia ml-1) followed by PPRC-14 and PPRC-51 (3.5x 10 5 and 3.9x 10 5 conidia ml-1 , respectively). In conclusion, the isolates PPRC-2, PPRC-14, PPRC-51, PPRC-GG and PPRC-HH, can be considered as a potential candidates in the development of mycoinsectisdes against S. zeamais.
