Patogenicidad del hongo Beauveria bassiana (Bals.) Vuill. sobre la chinche Monalion dissimulatum distant plaga del cacaotero Teobroma Cacao L.

Previus test with several entomopathogenic fungus species on Monalonion dissimulatum Distant bug (Hem.; Miridae) gave priority to 1he pathogen Beauveria bassiana (Bals.) Vuill. Two B. bassiana strains were evaluated: one of them comming from Metamasius hemipterus sericeus (Olivier) (Col.; Curculionidae) (Bb T 011) and the other isolated from M. dissimulatum (Bb 012), to 1 x 106,2.5 X 103,5 X 108,7.5 X 103 and 1 x 109 conidium/ml increasing dosage. All insects treated independently of its biologycal state of development were susceptibles to 1he pathogenic attack of 1he two strains. For OO1hfungis strains 1he dosage at which a higher percentage of significant mortality was obtained ranged between 2.5 x 103 and 7.5 x 1011 conidium/ml with mortality was ranged between 33.75 -49.75 and 43.75 - 62.5 for Bb T 011, 68.75 - 86.87 and 78.12- 89.37 for Bb 012 in 10 and 15 days respectivetly.
