“…Our results showed that Metarhizium and Hypocrea isolates elicited high mortality with quicker killing speed and lower LT 50 values than Beauveria isolates. The higher virulence effect of Metarhizium isolates than that of Beauveria isolates confirms earlier reports on similar patterns of activity with these fungal pathogen species [7,13,[51][52][53][54][55]. Metarhizium brunneum Cb15-III, M. anisopliae ICIPE 30 and ICIPE 60, and H. lixii F3ST1 were the most virulent against the tested termite species.…”

This study was conducted in the scope of developing a sustainable effective approach against subterranean termite pests using entomopathogenic and endophytic fungus-based biopesticides. Termites, Odontotermes spp. workers, were tested for their susceptibility to 15 entomopathogenic fungal isolates through the direct spraying of conidia suspensions at 1 × 108 conidia/mL. In general, all the isolates screened were pathogenic, with 100% mortality 4–7 days post-inoculation. However, the most virulent isolates were Metarhizium brunneum Cb15-III; the M. anisopliae isolates ICIPE 30 and ICIPE 60; Hypocrea lixii F3ST1; and the Beauveria bassiana isolates ICIPE 279, ICIPE 706 and ICIPE 662. These isolates were further tested for their endophytic colonization of cocoa seedlings using seed soaking, soil drench and foliar spray at 1 × 108 conidia/mL. The colonization of the plant tissues by the fungi was determined using a culture-based technique. Only the B. bassiana isolates ICIPE 706 and ICIPE 279, and H. lixii F3ST1 colonized the cocoa seedlings, with varied colonization rates among isolates and inoculation methods. Three naturally occurring endophytes—Trichoderma asperellum, Fusarium solani and F. redolens—were also isolated from the cocoa seedling tissues. These findings suggest that cocoa seedlings are conducive to endophytic fungal growth either occurring naturally or from artificial inoculation Our findings could possibly lead to an innovative approach to the management of herbivory and subterranean termite pests in cocoa agroforests.

“…Pik-Kheng et al (2009) however reported pathogenicity of isolates of M. anisopliae causing 100% mortality at 1x10 7 conidia ml -1 within 3 days post-inoculation but against on a different genus, Coptotermes curvignathus. Sileshi et al (2013) reported that at the highest concentration of 1x10 9 conidial ml -1 , both B. bassiana and M. anisopliae isolates caused 100% mortality of Macrotermes worker termite population after sixth days of exposure.…”

Odontotermes obesus (Rambur) is an important termite pest of tea of North East India. The current study shows that a novel strain of Metarhizium anisopliae (Metarhizium anisopliae strain DULS TTRA, Accession no. KT 119358) a tea soil fungus is highly pathogenic to both worker and soldier caste of Odontotermes obesus in in-vitro condition. Efficacy of the experimental fungi further assessed by comparing with commercial formulation showed to have less LT50 and LC50 than the established virulent strain. We recommend the strain as a potential bio-control candidate against Odontotermes obesus.

“…isolates at higher concentration registered higher mortality [40,58]. Addisu et al also suggested that the use of EPF at higher concentrations is an eco-friendly effective mycoinsecticides that causes more than 95% mortality of Macrotermes [59]. All the fungal products varied in ability to infect June beetle larvae, and their impact on mortality largely depended on the conidial concentrations applied and the elapsed time after application [45].…”

“…PPRC-27J and PPRC-44BC isolates showed promising result while, EPF infection usually takes 5 to 10 days to kill an insect [60]. Addisu et al reported that the isolate had LT 50 ranging from 7.74 days in M. anisopliae isolate PPRC-2 to 8.80 days in B. bassiana isolate 9609 [59]. Cheraghi et al revealed that B. bassiana and M. anisopliae are highly pathogenic to An.…”

Antestia bug (Antestiopsis intricata) is the major coffee insect pest affecting coffee productions in Ethiopia.Therefore, the study was carried out to evaluate entomopathogenic fungi based management options for antestia bug control. The efficacy test of entomopathogenic fungi was done under laboratory condition in Jimma Agricultural Research Center, Entomology and Pathology laboratories. The entomopathogenic fungi isolates were brought from Haramaya University and Ambo Agricultural Research Center. Seven isolates of Beauvaria bassiana (DLCO-12, APPRC-0247, DLCO-90, DLCO-56, DLCO-76, PPRC-44BC, and PPRC-27J) and four isolates of Metarhizium ansopliae (PPRC-51, DLCO23A, DLCO-91 and PPRC-02BC) species were tested for germination. Completely Randomized Design with three replications and probit analysis were used for data analysis by using SAS, GenStat and Microsoft excel. Eight isolates: APPRC 0247, DLCO 90, DLCO 56, DLCO 76, PPRC-44BC, PPRC-27J, PPRC-51 and PPRC-02BC which recorded higher germination were used for pathogenicity test against antestia bugs. All the tested isolates killed antestia bugs but their levels of efficacy differ across exposure time. Among tested isolates, PPRC-44BC and PPRC-27J registered complete mortality against antestia bugs and lower median lethal time, LT 50 (9.98 and 10.98 days, respectively). As a result these were taken as promising isolates and used for further isolates rate test. PPRC-44BC and PPRC-27J isolates applied at 1x10 8 conidia ml -1 killed all the tested antestia bugs in shorter exposure time. Even though PPRC-44BC and PPRC-27J isolates showed promising results under laboratory conditions, it needs further investigations on its formulation and under field conditions. Isolations of biocontrols from natural coffee growing areas and the effect of biocontrols against natural enemies should be studied.
