“…Entomopathogenic fungi have been recommended since they are effective and present a low risk for humans and other mammals. Some of these fungi are M. anisopliae and B. bassiana, evaluated by Quesada-Moraga et al (2004) in nymphs and adults of Periplaneta americana. These two genera of fungi, Metarhizium and Beauveria, are generally easily cultured and formulated (Glare et al 2002).…”

The greater wax moth Galleria mellonella L. (Lepidoptera: Pyralidae) is occasionally found in beehives and is a major pest of stored wax. Entomopathogenic fungi have recently received attention as possible biocontrol elements for certain insect pests. In this study, 90 isolates of Beauveria bassiana and 15 isolates of Metarhizium anisopliae were screened for proteases and lipases production. The results showed significant variations in the enzymatic action between the isolates. In the bioassay, the selected isolates evinced high virulence against the 4th instar of the G. mellonella larvae. The isolates BbaAUMC3076, BbaAUMC3263 and ManA-UMC3085 realized 100% mortality at concentrations of 5.5×10 6 conidia ml −1 , 5.86×10 5 conidia ml −1 , and 4.8×10 6 conidia ml −1 , respectively. Strong enzymatic activities in vitro did not necessarily indicate high virulence against the tested insect pest. The cuticle of the infected larvae became dark and black-spotted, indicating direct attack of fungus on the defense system of the insects. The LC 50 values were 1.43× 10 3 , 1.04×10 5 and 5.06×10 4 for Bba3263AUMC, Bba3076AUMC and Man3085AUMC, respectively, and their slopes were determined by computerized probit analysis program as 0.738±0.008, 0.635± 0.007 and 1.120±0.024, respectively.

“…Different studies with entomopathogenic fungi have shown effects over the reproductive potential of infected females. Castillo et al (2000) show that Metarhizium anisopliae affect females fecundity of Ceratitis capitata Wiedemann, as well as Blatella germanica (Linneo) (Quesada-Moraga et al, 2004) and Anopheles gambiae (Giles) (Scholte et al, 2006), among other species.…”

Obscure mealybug, Pseudococcus viburni (Signoret), is a cosmopolitan pest that causes damage by suction of vascular juices and the production of honeydew, as well as for being a quarantine insect. Within control options, entomopathogenic fungi are a good alternative, nevertheless, more research is needed. In this research, the Metarhizium anisopliae var. anisopliae (Metschnikoff) isolate Qu-M984 was evaluated on P. viburni under laboratory conditions. Virulence was evaluated by lethal dose 50 (LD 50 ) and lethal time 50 (LT 50 ), for each of the four life stages of the female. The doses tested were 10 5 , 10 6 , 10 7 and 10 8 conidia mL -1 . Also fecundity, egg size, fertility, and longevity of adult females were evaluated at doses of 10 5 and 10 6 conidia mL -1 , the evaluations were made every 2 d throughout the insect life time. The LD 50 and LT 50 obtained were variable for each life stage, although without statistical differences among life stages (P > 0.05), ranging from LD 50 = 7.3 × 10 5 to 4.9 × 10 9 conidia mL -1 and LT 50 = 7.74 to 9.97 d at 10 8 conidia mL -1 . Significant differences (P ≤ 0.05) were observed on longevity at 10 6 conidia mL -1 . Longevity was 29% less compared to the control. This result on longevity at relatively low dose is relevant due to the fact that decrease possibilities to find live quarantine insects at the moment of harvest. Fertility, fecundity and egg size showed no differences (P > 0.05).
