Abstract Unfed adult Ixodes scapularis Say were treated with spores of the entomopathogenic fungus Metarhizium anisopliae Metschnikoff in the laboratory and in the field. An M. anisopliae suspension containing 4 × 109 spores per milliliter caused 96% mortality in the laboratory, versus 53% mortality among field-treated ticks. The LC50 value for unfed adult I. scapularis in the laboratory was 4 × 107 spores per milliliter. Our results indicate that M. anisopliae was highly pathogenic to unfed… 
Pathogenicity of Metarhizium anisopliae (Deuteromycetes) and permethrin to Ixodes scapularis (Acari: Ixodidae) nymphs
TLDR
To assess whether a chemical acaricide would synergistically enhance pathogenicity of the fungus, the authors challenged unfed nymphal I. scapularis with combinations of M. anisopliae and permethrin in two separate bioassays, supporting neither synergism nor antagonism.
Effectiveness of Metarhizium anisopliae (Deuteromycetes) against Ixodes scapularis (Acari: Ixodidae) engorging on Peromnyscus leucopus.
TLDR
Targeting I. scapularis ticks engorging on white-footed mice with an effective biological control agent, such as the fungus Metarhizium anisopliae, could be an effective and relatively safe control technique.
Mortalities induced by entomopathogenic fungus Metarhizium anisopliae to different ticks of economic importance using two formulations
TLDR
The results indicate that the type of conidia formulation is critical to the performance of fungi as biological control agents for ticks.
Evaluation of Metarhizium anisopliae Strain F52 (Hypocreales: Clavicipitaceae) for Control of Ixodes scapularis (Acari: Ixodidae)
TLDR
Field efficacy of an emulsifiable concentrate formulation of the entomopathogenic fungus Metarhizium anisopliae strain F52 for the control of Ixodes scapularis nymphs was evaluated at residential sites in northwestern Connecticut in 2007 and could provide another tool for the integrated approach to managing ticks in the residential landscape.
Laboratory evaluation of three strains of the entomopathogenic fungus Metarhizium anisopliae for controlling Dermanyssus gallinae
TLDR
The pathogenicity of three strains of the entomopathogenic fungus Metarhizium anisopliae on different life stages of Dermanyssus gallinae was evaluated in the laboratory and it was concluded that it was concentration and time dependent.
Pathogenicity of the entomopathogenic fungus
Rhipicephalus evertsi evertsi is an economically-important tick of livestock in Africa mainly due to its ability to transmit Babesia equi to horses, Anaplasma marginale to cattle and to cause
Sublethal Effects of Metarhizium anisopliae (Deuteromycetes) on Engorged Larval, Nymphal, and Adult Ixodes scapularis (Acari: Ixodidae)
TLDR
It is indicated that M. anisopliae reduces fitness (fecundity and body mass) in all active I. scapularis stages and indicates that its impact as a biocontrol agent might be higher than that suggested by direct mortality alone.
Pathogenicity of the entomopathogenic fungus Metarhizium anisopliae to the red-legged tick, Rhipicephalus evertsi evertsi
TLDR
The pathogenicity and hence the bio-control potential of Metarhizium anisopliae to eggs and all other off-host stages of R. evertsi, an economically-important tick of livestock in Africa, is investigated.

TLDR
The studies developed in the Universidade Federal Rural do Rio de Janeiro demonstrate that some isolates of the fungi Metarhizium anisopliæ and Beauveria bassiana are pathogens for ticks and their action effects the mortality of ticks and reduces the populational levels in subsequent generations.

TLDR
The pathogenicity of five species of entomopathogenic fungi to the various developmental stages of Boophilus annulatus ticks was compared under laboratory conditions and prevented or reduced the egg laying capability of the ticks several days before their death.

TLDR
Entomopathogenic nematodes may be useful as an alternative management method for I. scapularis populations, and may be more acceptable than acaricidal chemicals for use in infested areas.
