“…Surfactin produced by Bacillus amyloliquefaciens G1 showed insecticidal potency against the green peach aphid, Myzus persicae, by affecting the aphid cuticles and inducing significant dehydration of the cuticle membrane to cause death [77]. Moreover, Khedher et al (2015) [16] have reported the potential of B. amyloliquefaciens AG1 biosurfactant to control the Tuta absoluta larvae.…”

Biosurfactants are amphipathic surface-active molecules produced by bacteria, fungi, and yeast. Owing to their low toxicity, high degree of biodegradability, optimal activity at extreme environmental conditions, and environmental friendly nature, biosurfactants have received attention in pest management. Most recently, the insecticidal activities of the biosurfactants obtained from different bacterial species have been reported. Therefore, considering the role of biosurfactants in novel insecticide production and environmentally safe insect pest management, we reviewed the isolation and identification of the biosurfactant-producing bacteria, the production methods of biosurfactants, and their potential applications in insect pest management, as well as delineated the possible future research areas. Finally, we concluded that, in the near future, biosurfactants will be the green pesticides that will replace the synthetic pesticides, and thus, for the discovery of novel insecticides, biochemical and molecular approaches, such as genomic and transcriptomic studies, are appreciable.

“…Das and Mukherjee (2006) and Geetha et al (2011) reported mosquito larvicidal and pupicidal activities of cyclic lipopeptides producing by B. subtilis and B. amyloliquefaciens strains, respectively. Yun et al (2013) also showed that surfactin produced by B. amyloliquefaciens G1 has insecticidal property against Green peach aphid (Myzus persicae). However, the insecticidal activity of metabolites produced by B. amyloliquefaciens and their mode of action remains unknown and needs to be elucidated.…”

“…Our results suggest that development of a program to select bacterial endophytes to improve hosta resistance to herbivores and pathogens could yield positive results if enough endophytes are screened. Yun et al (2013) found that the lipopeptide surfactin showed aphicidal activity. However, in our experiment, we did not see a significant detrimental effect on larvae fed with leaves dipped in lipopeptides (L+) (t-test, p = .3289, df = 24).…”

A total of 84 bacterial endophytes were isolated from seeds of 6 cultivars of ornamental hostas, and they were identified to 5 species based on morphological characteristics and 16S rDNA sequence analysis. Among them, the strain 'Blu-v2', which was isolated from the seeds of cultivar 'Blue Umbrella' and identified to be Bacillus amyloliquefaciens, showed highest antifungal activity and capacity to deter feeding by Fall armyworms (Spodoptera fruigiperda). Lipopeptides in cultures of Blu-v2 were determined using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) and its antifungal activities were verified. However, the lipopeptide preparation did not show toxicity to larvae of Fall armyworms. In a greenhouse experiment, Blu-v2 was inoculated into small plantlets of hosta (cultivar 'Rainforest Sunrise'). The leaves of plants with bacteria (endophyte-infected = E+) and without bacteria (endophyte-free = E−) were used in seven-day feeding experiments employing fourth-instar larvae of Fall armyworms. We found that there was a significant decrease in the weights of larvae fed with E+ compared to E− plants; and the mortality rate of larvae fed with E− leaves was lower (3.33%) compared to that of larvae fed with E+ leaves (30%). Based on our studies, we suggest that endophytic B. amyloliquefaciens strain Blu-v2 has potential value as a biocontrol agent to reduce damage from fungal diseases and insect pests of hosta cultivars.
