“…Previous studies have shown that B. bassiana and M. anisopliae have great potential as biological control agents for different arthropod species 5,6 . In the current study, C. felis felis eggs exposed to Bb747 at 10 8 conidia mL −1 had low hatchability after 36 h compared to controls, while those exposed to Bb986 showed low hatchability after 48 h (Table 1).…”

Ctenocephalides felis felis is a flea species that parasitizes dogs and cats. The current study verified the in vitro virulence of the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana to eggs and adults of C. felis felis. The fungal isolates were cultivated on rice grains in plastic bags. Conidial suspensions were then prepared by immersing the grains in Tween 80 aqueous solution (0.01%). Eggs and adults of C. felis felis were obtained from a laboratory colony. Experiments were composed of one control and four treatment groups (10(5), 10(6), 10(7), and 10(8) conidia mL(-1)). Both insect pathogens inhibited egg hatchability and caused adult mortality. Among isolates used in this study, M. anisopliae (isolate E9) was the most successful at inhibiting hatching, while B. bassiana (isolate 986) was the most powerful for causing mortality in adults. The results indicate that these entomopathogenic fungi have promising potential for use in controlling both C. felis felis egg and adult stages.

“…However, the ability of B. microplus to develop resistance to acaricides, consumer's demands for chemical free foods, and the negative environmental effects of acaricides call for the development of alternative strategies (Kay and Kamp 1994). Therefore, alternative methods for tick control, such as biological control using filamentous fungi, chiefly, M. anisopliae (Correia et al 1998;Kaaya and Hassan 2000) and Beauveria bassiana (Monteiro et al 1998b), have been pursued.…”

Morphological Alterations of Metarhizium anisopliae During Penetration of Boophilus microplus Ticks

et al. 2005

Chronological histological alterations of Metarhizium anisopliae during interaction with the cattle tick Boophilus microplus were investigated by light and scanning electron microscopy. M. anisopliae invades B. microplus by a process which involves adhesion of conidia to the cuticle, conidia germination, formation of appressoria and penetration through the cuticle. Twenty-four hours post-infection conidia are adhered and germination starts on the surface of the tick. At this time, the conidia differentiate to form appressoria exerting mechanical pressure and trigger hydrolytic enzyme secretion leading to penetration. Massive penetration is observed 72 h post-inoculation, and after 96 h, the hyphae start to emerge from the cuticle surface to form conidia. The intense invasion of adjacent tissues by hyphae was observed by light microscopy, confirming the ability of M. anisopliae to produce significant morphological alterations in the cuticle, and its infective effectiveness in B. microplus.

“…However, engorged R. microplus and R. sanguineus females were more susceptible to entomopathogenic fungi in comparison to H. excavatum females (Gindin et al, 2003). Further, 100% susceptibility of eggs to fungi were also reported (Gorshkova, 1966;Monteiro et al, 1998;Kaaya, 2000). Elham et al (2013) studied the effect of Scopulariopsis brevicaulis fungal spore suspension and culture filtrate on larvae, nymphs and adults of H. anatolicum and high mortality of larvae and reduced biotic potential of the adults was reported.…”

The Hyalomma species of ticks have gained additional attention due to their role in the transmission of Theileria annulata infection in animals and the Crimean-Congo Haemorrhagic Fever (CCHF) virus in humans. Apart from these, many other pathogens viz., other species of Theileria, a few species of Babesia, Rickettsia and viruses are either maintained or transmitted by this tick species. The medium to large size species with longer proboscis has inflicted additional burden on the overall impact of tick infestations. Being a multi-host species, management of the species is very challenging. Presently, the traditional method of tick management using chemical acaricides is found insufficient and unsustainable. Henceforth, the overall burden of tick infestations and tick-borne diseases are increasing gradually. After the successful development of vaccines against cattle tick, Rhipicephalus microplus, the anti-Hyalomma vaccine is considered a feasible and sustainable management option. In the recent past research on herbal acaricides and its possible application for tick control seems promising. Other eco-friendly methods are still under experimental stage. The present review is focused on impact of Hyalomma species infestation on human and animal health with special emphasis on progress on its sustainable management.
