Enset root mealybug, Cataenococcus ensete Williams and Matile-Ferrero, (Homoptera: Pseudococcidae) is an economically important pest on enset. Adults and nymphs of overlapping generations feed on the corms and roots of enset and are difficult to control once established. Isolates of Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnickoff) Sorokin that originated from Ethiopia were evaluated for their efficacies against enset root mealybugs under laboratory, pots and field conditions. Of the tested isolates, two strains (FF and PPRC-56) of B. bassiana were found to be highly pathogenic to adults, causing 97 and 100% mortality, respectively 20 days after inoculation under laboratory conditions. On the other hand, the isolates PPRC-56, FF, PPRC-6 and Mm induced mean mortalities of 97, 95, 96 and 83%, respectively, to the adult enset root mealybugs on the pot experiment, and 51.33, 38.67, 29.33 and 19.33% mortality at the first site and 54.00, 42.67, 32.00 and 25.33% at the second site, respectively, in field experiments. The study showed B. bassiana and M. anisopliae can be used in the integrated management of enset root mealybug.
Research highlights
► Enset is a multipurpose crop which supports about 15 million people as a staple food in Ethiopia.
► The production of enset is threatened by root melaybug damage.
► Indigenous entomopathogenic fungi species were evaluated for their efficacy against the enset root melaybug.
► The manuscript presents the option of managing enset root mealybug with the use of entompopathogenic fungi and indigenous strains could be considered.
► It is also a contribution to the knowledge of root mealybug management with the use of entomopathogenic fungi.
