“…Among potential biological control agents, entomopathogenic fungi, nematodes and parasitic wasps are the most promising candidates. In Germany, the fungus Metarhizium anisopliae (Metschnikoff) and the nematode species Steinernema carpocapsae (Weiser) are currently under investigation for their effectiveness in tick control (Hartelt et al. 2008).…”

The parasitic wasp Ixodiphagus hookeri parasitizes hard ticks and is therefore considered as a potential candidate for biological control of ticks. However, there are still considerable gaps of knowledge about the biology of I. hookeri, especially for European populations. Thus, the present study was performed to assess important life‐history parameters of the parasitoid in Germany. Field studies accomplished in three successive years revealed that unfed Ixodes ricinus nymphs are infested by the parasitoid at a low but constant rate of 1.9–3.8% and that adult wasps are present only during a short period in late summer. The mean developmental time of wasps in I. ricinus nymphs ranged from 28 to 70 days under constant laboratory conditions and was prolonged in the second half of the year. Bioassays on parasitization and host preference behaviour showed that unfed nymphs of the host species I. ricinus are significantly preferred in experiments, in which unfed and engorged larvae as well as fully engorged nymphs were offered as alternatives. The marsh tick Dermacentor reticulatus was not accepted as an alternative host. Our data show that the investigated I. hookeri populations differ markedly from populations in other regions of the world in many aspects. The adaptation of different strains to local conditions explains the limited success of imported strains in earlier biological control attempts and highlights the importance of doing research to enhance the control potential of native strains.

“…The susceptibility of different tick species to entomopathogenic fungi can be high. However, great variability among strains has been reported (e.g., Samish et al 2001;Gindin et al 2002;Hartelt et al 2008;Leemon & Jonsson 2008). This variability might be attributed to unfavourable and fluctuating environmental conditions, which affect the virulence of the fungi inoculum and retard the killing process (Zimmermann 1982;Wraight et al 2007).…”
