Fusarium graminearum is a pervasive plant pathogenic fungal species. Biological control agents employ various strategies to weaken their targets, as shown by Bacillus species, which adopt various mechanisms, including the production of bioactive compounds, to inhibit the growth of F. graminearum. Various efforts to uncover the antagonistic mechanisms of Bacillus against F. graminearum have been undertaken and have yielded a plethora of data available in the current literature. This perspective article attempts to provide a unified record of these interesting findings. The authors provide background knowledge on the use of Bacillus as a biocontrol agent as well as details on techniques and tools for studying the antagonistic mechanism of Bacillus against F. graminearum. Emphasizing its potential as a future biological control agent with extensive use, the authors encourage future studies on Bacillus as a useful antagonist of F. graminearum and other plant pathogens. It is also recommended to take advantage of the newly invented analytical platforms for studying biochemical processes to understand the mechanism of action of Bacillus against plant pathogens in general.

Lycorma Delicatula

With the recent introduction of the non-native spotted lanternfly (Lycorma delicatula) to the USA, research and concern regarding this insect is increasing. Though L. delicatula is able to feed on many different plant species, its preference for the invasive tree-of-heaven (Ailanthus altissima) is apparent, especially during its later life stage. Therefore, management focused on A. altissima control to help limit L. delicatula establishment and population growth has become popular. Unfortunately, the control of A. altissima is difficult. Verticillium nonalfalfae, a naturally occurring vascular-wilt pathogen, has recently received attention as a potential biological control agent. Therefore, we studied if L. delicatula fourth instars or adults could vector V. nonalfalfae from infected A. altissima material to healthy A. altissima seedlings in a laboratory setting. We were unable to re-isolate V. nonalfalfae from the 45 A. altissima seedlings or from the 225 L. delicatula utilized in this experiment. We therefore, found no support that L. delicatula could effectively vector this pathogen between A. altissima in laboratory conditions. Since L.delicatula’s ability to vector V. nonalfalfae has implications for the dissemination of both this beneficial biological control and other similar unwanted plant pathogens, future research is needed to confirm these findings in a field setting.

Selection Of

The search for commercially viable entomopathogenic fungi for use in integrated pest management programs involves several steps. Fungal species must first be obtained from diseased insects or the environment and identified. Then, they must be evaluated under laboratory conditions to identify the most promising candidates. Because of that, bioassays must be repeatable and reliable to determine accurate pathogenicity or virulence. Variability in results may be caused by the variation in the components of an assay. However, the availability of a standardized bioassay is limited. Few reports detail the methods used to develop bioassays for a specific purpose and, without these details, it is difficult to develop bioassay methodologies suitable to evaluate the fungus-host relationship. We described a protocol based on the immersion method to evaluate entomopathogenic fungi (larval and adult stages), that can be reproduced to reduce variability. This protocol can be used in several stages of biopesticide development: selection of the biological control agent, characterization of the microorganism, formulation compatibility, and in vitro evaluation of efficacy.
