Zusammenfassung
Tree endophytic fungi play an important role in
reducing insect herbivory, either by repelling them or kill-
ing them directly. Identifying which fungi show such activ-
ity could lead to new environmentally friendly pesticides.
In this study, the Mediterranean basin climate conditions
are projected to harshen in the next decades, will increase
vulnerability of tree species to pest invasions. Endophytic
fungi were isolated from wood and leaves of Quercus pyr-
enaica, Q. ilex and Q. suber and tested for virulence against
adults of the mealworm beetle, Tenebrio molitor L. using a
direct contact method. Only 3 of 111 sporulating isolates had
entomopathogenic activity, all identified as Lecanicillium
lecanii. The pathogenicity of L. lecanii on T. molitor resulted
in a median lethal time (TL50) of 14–16 d. Compared with
commercial products, L. lecanii caused faster insect death
than the nematode Steinernema carpocapsae and nuclear
polyhedrosis virus (no effect on T. molitor survival), and
slower than Beauveria bassiana (TL50 = 5), Beauveria pseu-
dobassiana (TL50 = 8d) and Bacillus thuriengensis (80%
mortality first day after inoculation). Mortality was also
accelerated under water stress, reducing TL50 by an addi-
tional 33%. Remarkably, water stress alone had a comparable
effect on mortality to that of L. lecanii isolates. This study
confirms T. molitor as a good model insect for pathogenicity
testing and agrees with management policies proposed in the
EU Green Deal.
