Evaluation of Entomopathogenic Fungi against Coffee Antestia Bug, (Antestiopsis Intricate) Under Laboratory Condition at Jimma

The Efficacy of Entomopathogenic Fungi for Antestia Bugs (<i>Antetiopsis intircata</i>: Pentatomidea, Hemimptera) Control

“…On other hand, since antestia bug is big in size it required higher concentration for kill. This is in-line with Tamiru et al who reported PPRC-56 and PPRC-2 recorded higher mortality of antestia bug at higher concentration [44]. The study agreed with Sanjaya et al who found the maximum mortality of the tested insect species at higher concentration (1×10 8 conidia/ml) [40,47,56].…”

“…This finding agrees with Nahayo and Bayisenge, and Sevim et al who conducted study on B. bassiana fungus to control antestia bugs and concluded the pathogenecity of the fungus against antestia bugs [32,44]. Erler and Ates, and Tamiru et al also indicated that B. bassiana product was more effective than the formulations of M. anisopliae product [45,44]. Similarly, Samuels et al reported that B. bassiana as one of the most promising biological control agents for coffee berry borer and an effective component within an integrated pest management program in Mexico [46].…”

“…The study indicated that B. bassiana species, PPRC-44BC and PPRC-27J isolates were more pathogenic than M. anisopliae species. This finding agrees with Nahayo and Bayisenge, and Sevim et al who conducted study on B. bassiana fungus to control antestia bugs and concluded the pathogenecity of the fungus against antestia bugs [32,44]. Erler and Ates, and Tamiru et al also indicated that B. bassiana product was more effective than the formulations of M. anisopliae product [45,44].…”

“…Feng et al also indicated that B. bassiana has proved to be competitive with chemical insecticides for forest and farm insect pests in China [48]. And Tamiru et al promoted PPRC-56 isolate, B. bassiana against antestia [44].…”

“…PPRC-44BC and PPRC-27J isolates showed complete mortality after 18 th and 21 st days of isolates application, respectively. But, Tamiru et al reported that PPRC-56 and PPRC-2 killed antestia bug above 70% within twenty days [44]. Kooyman et al reported that 80% reduction in grasshopper populations was recorded in treated plots after twenty-one days of isolates application [50].…”
