English Abstract

Geotrogus deserticola Blanch.

(Coleoptera: Scarabaeidae) is one of the most important insect pests in Algeria.

Larvae cause severe damages to the roots of various cultural crops.

Laboratory studies were conducted to determine the potential of the fungus Metarhizium anisopliae (Metsch.) Sorokin (Deuteromycetes: Hyphomycetes) for the control of the pest larvae.

Positive results were obtained when larva! instars were sprayed with different concentrations of fungus eomdia (5, 10.

20, 30, 40 x 10J conidiaml).

Concentrations at 30 and 40 x 10J conidiaml showed S2 and 93.3% larval mortality, respectively.

These results revealed that the rates of infection and mortality were significantly related to the concentration of eonidia m the corresponding samples.

The larval mortality percentage decreased with larval instars development (r = - 0.97).

M anisopliae can be considered as a promising biocontrol agent of G.

deserticola.

but field experimentation is necessary to substantiate these finding.
