“…Our study did not measure blood meal size or count the number of unlaid eggs. However, Scholte and others 11 found that An. gambiae infected by M. anisopliae took fewer and smaller blood meals and laid fewer eggs per batch.…”

“…Entomopathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae have been shown to reduce human biting by Anopheles spp., 11 reduce vector competence, 12 and work equally well against insecticide-resistant mosquitoes as against non-resistant strains. 13,14 Infective fungus spores have been applied with preliminary success in the field to sheets of black cloth, 9,15 clay pots, 16 and outdoor resting boxes 17 to reduce mosquito survival, with minimal contribution to airborne spore load.…”

Abstract. The fungus Beauveria bassiana reduces Aedes aegypti longevity in laboratory conditions, but effects on survival, blood-feeding behavior, and fecundity in realistic environmental conditions have not been tested. Adult, female Ae. aegypti infected with B. bassiana (FI-277) were monitored for blood-feeding success and fecundity in the laboratory. Fungal infection reduced mosquito-human contact by 30%. Fecundity was reduced by (mean ± SD) 29.3 ± 8.6 eggs per female per lifetime in the laboratory; egg batch size and viability were unaffected. Mosquito survival, blood-feeding behavior, and fecundity were also tested in 5 meter + 7 meter + 4 meter semi-field cages in northern Queensland, Australia. Fungal infection reduced mosquito survival in semi-field conditions by 59-95% in large cages compared with 61-69% in small cages. One semi-field cage trial demonstrated 80% reduction in blood-feeding; a second trial showed no significant effect. Infection did not affect fecundity in large cages. Beauveria bassiana can kill and may reduce biting of Ae. aegypti in semi-field conditions and in the laboratory. These results further support the use of B. bassiana as a potential biocontrol agent against Ae. aegypti.

“…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).

“…Dentre os entomopatógenos, destacam-se Beauveria bassiana (Balsamo) Vuillemin e Metarhizium anisopliae (Metschnikoff) Sorokin que vêm sendo utilizados com sucesso no controle de pragas, tanto no Brasil como em outros países (ALVES, 1998). Trabalhos sobre a ação desses fungos contra diferentes espécies de dípteros mostraram resultados promissores para seu emprego em programas de controle biológico (EKESI et al, 2002;DIMBI et al, 2003;KONSTANTOPOULOU & MAZOMENOS, 2005;SCHOLTE et al, 2006;COSSENTINE et al, 2010), o que sugere que Z. indianus também pode ser suscetível a estes entomopatógenos.…”
