“…Three concentrations (10 6 , 10 7 and 10 8 CFU/ml) were used in this study, and their efficacy was checked after 2 days up to 2 weeks in laboratory experiment and the most promising results were given by the highest concentration. Trinh et al (2020) also used the same concentration against aphid, and his results were supportive to the obtained findings that the efficacy of EPF has increased by increasing the concentration. Time interval is also an important for EPF, as the maximum mortality was observed at 14 DAT.…”

Background Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae) is the most destructive pest of bitter gourd. Conventionally, it is controlled by chemical insecticides despite their hazardous impacts. Entomopathogenic fungi are considered as eco-friendly and safer alternative of chemical. This study aimed to evaluate the efficacy of Beauveria bassiana and Metarhizium anisopliae against B. cucurbitae on bitter gourd. Results The study revealed that B. bassiana and M. anisopliae were efficient against B. cucurbitae in controlled as well as field conditions. Both mode of application (i.e., contact and oral) were found to be effective; however, high efficacies of them were observed through contact application (73.43 and 59.72%), respectively. Pathogenicity of both fungi increased with increase in concentration and time intervals. Under field conditions, significantly low fruit infestations and significantly a high population reduction of B. cucurbitae were observed at 30 DAT when both fungi were applied with 108 CFU/ml concentrations. Conclusions Beauveria bassiana and M. anisopliae had the potential to be used against B. cucurbitae; however, the former showed high efficiency comparatively.

“…The potential use of Lecanicillium sp. in biological control against insect pests of crops has been demonstrated by many authors (Kim et al, 2007;Xie et al, 2019;Trinh et al, 2020), as an entomopathogen. Many findings carried out the biological control of plant diseases by Lecanicillium sp.…”

Early and late leaf spots caused by Cercospora arachidicola and Phaeoisariopsis personata respectively, are the most widespread peanut fungal diseases in West Africa. These diseases lead to notable crop losses in the rural area. In the recent decades, chemical fungicides are used to fight against crop losses, but these chemical substances cause big damages to the environment including the animals and human beings. Thus, the biological control is encouraged by scientific community and all government because it is well known to be safety and cost effective. For this reason, we investigated on the effectiveness of Lecanicillium lecanii on leaf spots of peanut in Burkina Faso. To do so, spore suspensions (10 6 spores / ml) from four strains of L. lecanii was used in vitro. The results revealed that L. lecanii 4181 inhibited the pathogen conidia germination up to 87%, as well as elongation germ tube with highest rate of 56%. Compared to the distilled water control, the severity scores vary between 5.7 and 8, but our results showed a notable decrease of score from 2.3 and 4.7. From our findings, the treatments with L. lecanii spore suspensions on peanut leaves significantly reduced the severity of leaf spots and may be potentially used to promote organic farming in West Africa.

Because of their negative effects on the environment, humans, and other organisms, chemical pesticides have been prohibited in many countries. Alternative microbial management is easy-to-implement, effective, and safe for humans and the environment. Fungus-based biopesticide products like kojic acid could commercialize as effective alternative chemical pesticides. Aspergillus oryzae ASU44 (OL314732) was isolated from hollyhock rhizosphere and identified using 18S rRNA gene sequencing. The strain showed high ability of kojic acid production especially after optimizing the production using 41-run Box-Behnken statistical design. Maximum kojic acid production was 46.53 g/l (predicted values 46.62 g/l) obtained in run number (23) using Glucose (150, g/l), Yeast extract (5 g/l), KH2PO4 (3 g/l), MgSO4.7H2O (0.5 g/l) and pH (3). The design was effective to applied with coefficient (R 2 ) 0.988, 0.986 (adjusted R 2 0.975, 0.972) for kojic acid (g/l) and dry fungal mass formation (g/l). The pathogenicity of the fungus and their kojic acid in addition to standard synthetic kojic acid was investigated to the cotton aphid, Aphis gossypii Glover (Homoptera: Aphididae). All treatments had a considerable impact on aphid mortality. The mortality rate was relative to the duration of exposure and the quantities of bio-pesticides agents. However, data revealed that as concentrations increased, the lethal time values decreased. Aspergillus oryzae ASU44 and its extract containing kojic acid were found effective against A. gossypii. As a result, this research suggests that these agents could be effective in aphid cotton management.
