“…Our observation revealed that all insects inoculated with M. phasmatodeae succumbed within 5 days. Considering the rapid onset, M. phasmatodeae holds promise as a biocontrol agent against stick insect outbreaks in forest ecosystems ( Sabbahi et al, 2022 ; Vivekanandhan et al, 2022 ; Perumal et al, 2023 ). However, for application in forest ecosystems, additional host specificity tests are necessary.…”

Phasmatodea, commonly known as stick insects, are recognized as noteworthy pests globally, impacting agriculture and forest ecosystems. Among them, the outbreak of Ramulus mikado has emerged as a notable concern in East Asian forests. Recently, Metarhizium phasmatodeae has been identified as utilizing stick insects as hosts. We have observed evidence of this entomopathogenic fungus infecting stick insects. Given the increase in these occurrences during the rainy period, this study investigated the relationship between the survival of R. mikado and the M. phasmatodeae infection during the rainy seasons of 2022 and 2023. We collected stick insects in two representative forests of the Republic of Korea and examined insect survival, fungal infection, and various environmental factors. No infections were detected in specimens collected in June before the rainy season, but from July onwards, both the mortality of R. mikado and the fungal infection substantially increased. By the last sampling date of each year, 75% (2022), 71.4% (2023) of the specimens were infected, and over 90% of the total individuals succumbed as a result. Fungi isolated from deceased R. mikado were successfully identified as M. phasmatodeae using morphological and taxonomic approaches. Various statistical analyses, including principal component analysis and modeling, revealed a robust association between fungal infection and the survival of stick insects. The results highlight the correlation between mass deaths of stick insects and fungal infection, particularly during the summer rainy season. These findings offer valuable insights for forecasting R. mikado population in the upcoming year and developing effective pest control strategies.

“…Entomopathogenic fungi (EPF) have been found as prospective biocontrol agents in the management of insect pest populations without affecting non-target insects (Sabbahi et al 2022). In addition, EPF can have a lethal impact not only on the initial insect host but also on other insect organisms but is limited to insect groups only.…”

Abstract. Rosa E, Damayanti RD, Yuswantoro J, Indra RN, Oktariana P, Mardianto MFF, Arifiyanto A. 2022. Pathogenicity of entomopathogenic fungi isolated from Periplaneta americana against Dolichoderus sp.. Biodiversitas 23: 5461-5468. Dolichoderus sp. was found to cause a problem for plants, buildings, and households. Many efforts have been made to regulate such animals, but they have not always been successful. Biological control has gained significance in studies as an alternative to chemical control, in which fungi and nematodes are among the successful microorganisms in managing insects. This study aimed to understand the toxicity impact of cockroach-entomopathogen against Dolichoderus sp. Isolated entomopathogens were then administrated to Dolichoderus sp. colonies under laboratory conditions to assess their mortality efficiency. The fungal suspension was sprayed on the ant colonies with concentrations of 107, 108, and 109 conidia/mL. Aspergillus carbonarius KIF3, and Penicillium sp. KIF4 were identified as entomopathogenic fungi. In this investigation, 15 individuals of Dolichoderus sp. were employed in each treatment, with three replications. Pure distilled water with 1% molasses and 0.1% Tween 80 was used as a positive control, whereas sterile distilled water was used as a negative control. The result showed that the entomopathogenic fungus Aspergillus carbonarius KIF3 significantly affected mortality in black ants when administered 109 conidia/mL conidial suspension. It was also observed that the presence of the Dolichoderus sp. population in nature is often associated with mealybugs. There is an opportunity to use an ecological control approach in black ant populations by utilizing entomopathogenic fungi.

“…The US Environmental Protection Agency (EPA) classifies biopesticides into three groups: (i) biochemical biopesticides derived from natural compounds; (ii) plant protectants; and (iii) microbial biopesticides, which include various microorganisms such as baculoviruses, fungi, bacteria, and nematodes. Insect-based biological control using entomopathogens (EPs) has the potential to reduce pollution and disruptions associated with the use of synthetic chemicals and their environmental impacts (Sabbahi et al, 2022).…”

This article aims to provide an overview of nanobiopesticides as a promising solution for sustainable and environmentally friendly pest control in agriculture. These formulations combine nanotechnology and biopesticides derived from plant extracts. The synthesis and characterization of plant extract-based pesticide nanoparticles are found to be more effective than using biopesticides alone. In this review, first, we examine the literature on the use of biopesticides, including both plant extract-based pesticides and biopesticides from microorganisms. Moreover, we review several studies on the combination of plant extract-based pesticides and biopesticides to enhance biopesticide efficacy. Finally, we discuss nanobiopesticides in supporting sustainable and environmentally friendly agriculture by utilizing biopesticides based on nanoparticles. Overall, this review highlights the promising prospects of plant extract-based nanobiopesticides and underscores their potential as effective and sustainable alternatives for pest management in modern agriculture.
