“…This species is commonly found indoors in dog kennels and homes and is known to be permethrin resistant and tolerant to fipronil, which are commonly used for its control [ 69 ]. In contrast, only 30–41% mortality after three weeks occurred in D. albipictus larvae that were sprayed with 1 × 10 6 –10 8 conidia/mL, respectively [ 52 ].…”

“…For example, fungi are not universal in their ability to cause mortality, and some reports have shown that increased application rates of Bb -GHA may be needed against some tick species to provide suppression comparable to the same rate of Mb -F52 under controlled laboratory conditions. For example, mortality of D. albipictus larvae was significantly less when treated with Bb -GHA (30–41%) in comparison to Mb -F52 (82–99%) when the two strains were applied at the same rates [ 52 ]. In contrast, Bb -GHA killed R. sanguineus sensu lato nymphs faster and caused greater sporulation than Mb -F52 [ 54 ].…”

There is a need for the development of sustainable, nonchemical tick management strategies. Mycoacaricide and mycoinsecticide product development worldwide has focused primarily on fungi in the genera Beauveria (Hypocreales: Cordycipitaceae) and Metarhizium (Hypocreales: Clavicipitaceae). Microbial biopesticides containing entomopathogenic fungi have potential in tick management. However, despite considerable progress in the development of fungal biopesticides over the past 20 years, the establishment of commercial products available for use against ticks continues to be slow. We reviewed published scientific literature and compiled a comprehensive list of reports of the effectiveness of commercial biopesticides based on the fungal genera Metarhizium and Beauveria and registered for use in the USA against ixodid ticks under laboratory and field conditions. We also report on results when these biopesticides were used as a part of integrated tick management. Until efficacious fungus-based products become more available, tick management will rely primarily on synthetic chemical acaricides, with natural-product acaricides as the alternative.

“…Lastly, direct approaches to winter tick management are being explored to lessen the impact of ticks on moose fitness. The naturally occurring Metarhizium anisopliae fungus found in the soil has shown detrimental effects on winter tick survival in the laboratory setting (Sullivan et al, 2020).…”

“…Little is known about the ecology, abundance, and management of winter ticks in their natural setting. Managers may use the potential "hotspots" results to focus field research (e.g., Sullivan et al, 2020) that could ultimately help break the negative impacts of the tick-moose cycle.…”

Moose Habitat Selection and Fitness Consequences During Two Critical Winter Tick Life Stages in Vermont, United States†

et al. 2021

The moose (Alces alces) is a charismatic species in decline across much of their southern distribution in North America. In the northeastern United States, much of the reduction has been attributed to winter tick (Dermacentor albipictus) infestations. Winter ticks are fairly immobile throughout all life stages, and therefore their distribution patterns at any given time are shaped largely by the occurrence of moose across the landscape during the peak of two critical time periods: fall questing (when ticks latch onto moose) and spring drop-off (when engorged female ticks detach from moose). We used recent land cover and lidar data within a dynamic occupancy modeling framework to estimate first-order habitat selection (use vs. non-use) of female moose (n = 74) during the tick questing and drop-off periods. Patch extinction and colonization rates between the fall questing and spring drop-off periods were strongly influenced by habitat and elevation, but these effects were diminished during the fall questing period when moose were more active across the landscape. From the fall questing period to the spring drop-off period, patches where colonization was high and extinction was low had higher proportions of young (shrub/forage) mixed forest at higher elevations. Further, we evaluated the fitness consequences of habitat selection by adult females during the fall questing period, when females and their calves acquire ticks. We compared Resource Selection Functions (RSF) for five females that successfully reared a calf to age 1 with five females whose calves perished due to ticks. Adult female moose whose offspring perished selected habitats in the fall that spatially coincided with areas of high occupancy probability during the spring tick drop-off period. In contrast, adult female moose whose offspring survived selected areas where the probability of occupancy during the spring drop-off was low; at present, natural selection may favor female adults who do not select the same habitats in fall as in spring. Our model coefficients and mapped results define “hotspots” that are likely encouraging the deleterious effects of the tick-moose cycle. These findings fill knowledge gaps about moose habitat selection that may improve the effectiveness of management aimed at reversing declining population trends.

“…It was proven to be effective against Amblyomma parvum [136] and Haemaphysalis qinghaiensis, such as B. bassiana [137]. In a trial on Dermacentor albipictus larvae, a spray application of M. anisopliae was more effective and active in a shorter time, such as M. brunneum, when compared to B. bassiana [138].…”

The present study aimed to review the papers dealing with the biological activity of fungi and bacteria against some mites and ticks of veterinary interest. In particular, the attention was turned to the research regarding acarid species, Dermanyssus gallinae and Psoroptes sp., which are the cause of severe threat in farm animals and, regarding ticks, also pets. Their impact on animal and human health has been stressed, examining the weaknesses and strengths of conventional treatments. Bacillus thuringiensis, Beauveria bassiana and Metarhizium anisopliae are the most widely employed agents. Their activities have been reviewed, considering the feasibility of an in-field application and the effectiveness of the administration alone or combined with conventional and alternative drugs is reported.
