Abstract

Bioassays were conducted to determine the susceptibility of eggs ofPerileucoptera coffeella Guerin-Meneville to different spore doses ofMetarhizium anisopliae (Metsch.) isolate CM-14 at 28±1°C and 95±5% R. H. The fungi was highly virulent against eggs. Larval mortality by the fungi was 100% in all cases. The larvae were infested inside the gallery or when they were seeking site for pupation. LD50 of fungi to eggs was determined to be of 4.6 mg/100 ml water.

Résumé

Des essais biologiques ont été conduits pour déterminer la sensibilité des œufs dePerileucoptera coffeella Guérin-Meneville à différentes doses deMetarhizium anisopliae (Metsch.) Sorokin souche CM-14, à 28±1°C et 85±5% H.R.

Le champignon s'est montré hautement virulent pour les œufs. On a obtenu une mortalité de 100% des chenilles à toutes les concentrations étudiées. Les chenilles mortes de mycose ont été trouvées à l'intérieur des galeries ou sur les feuilles quand elles étaient à la recherche d'abris pour se nymphoser.

La DL-50 du champignon pour les œufs deP. coffeella est de 4,6 mg/100 ml d'eau.
