BACKGROUNDEntomopathogenic fungi (EPF) are multifunctional microorganisms acting not only as biopesticides against insect pests but also as endophytes which regulate plant growth. The tomato leafminer, Phthorimaea absoluta (Tuta absoluta) is a devastating invasive pest of tomatoes worldwide. However, effective alternatives are needed for a sustainable management of this invasive pest. In this study, the functional effects of five EPF isolates Metarhizium flavoviride, M. anisopliae, M. rileyi, Cordyceps fumosorosea and Beauveria bassiana were evaluated on tomato growth promotion and pest protection against P. absoluta.RESULTSWhen directly sprayed with conidia, P. absoluta larvae showed high cumulative mortality of 100% to M. anisopliae under 1 × 108 conidia/mL, whereas M. flavoviride, B. bassiana, C. fumosorosea and M. rileyi caused cumulative mortality of 92.65%, 92.62%, 92.16% and 68.95%, respectively. Moreover, all five EPF isolates can successfully colonize tomato plants, whilst the colonization rate for each EPF depends on the inoculation method used. The most efficient inoculation method for M. flavoviride and M. rileyi was root dipping, for M. anisopliae and C. fumosorosea it was coating seed, and for B. bassiana it was foliage spraying. The highest plant colonization was obtained by M. flavoviride. Meanwhile, all these isolates promoted tomato plant growth upon inoculation. Furthermore, endophytic colonization of plants by the five EPF negatively affected the performance of P. absoluta, among them M. anisopliae and C. fumosorosea showed strong negative effects on the performance of P. absoluta.CONCLUSIONOur results highlight the potential of incorporating entomopathogenic fungi as endophytes in integrated pest management practices to protect tomatoes against P. absoluta. © 2023 Society of Chemical Industry.

“…While applications in this area are currently limited, the hypothesis holds significant potential and warrants further exploration. 4) The development of mixed microbial formulations with synergistic effect alongside EPF, such as ( Bacillus thuringiensis + Metarhizium species) pesticides, can offset the limitations of individual pesticides and enhance the control efficiency of EPF in field applications ( 210 , 213 ). These combined agents present a more socially acceptable strategy compared to genetically modified strains, as they entail lower safety risks.…”

Insects constitute approximately 75% of the world’s recognized fauna, with the majority of species considered as pests. Entomopathogenic fungi (EPF) are parasitic microorganisms capable of efficiently infecting insects, rendering them potent biopesticides. In response to infections, insects have evolved diverse defense mechanisms, prompting EPF to develop a variety of strategies to overcome or circumvent host defenses. While the interaction mechanisms between EPF and insects is well established, recent findings underscore that their interplay is more intricate than previously thought, especially evident across different stages of EPF infection. This review primarily focuses on the interplay between EPF and the insect defense strategies, centered around three infection stages: (1) Early infection stage: involving the pre-contact detection and avoidance behavior of EPF in insects, along with the induction of behavioral responses upon contact with the host cuticle; (2) Penetration and intra-hemolymph growth stage: involving the initiation of intricate cellular and humoral immune functions in insects, while symbiotic microbes can further contribute to host resistance; (3) Host insect’s death stage: involving the ultimate confrontation between pathogens and insects. Infected insects strive to separate themselves from the healthy population, while pathogens rely on the infected insects to spread to new hosts. Also, we discuss a novel pest management strategy underlying the cooperation between EPF infection and disturbing the insect immune system. By enhancing our understanding of the intricate interplay between EPF and the insect, this review provides novel perspectives for EPF-mediated pest management and developing effective fungal insecticides.

The tomato is one of the most nutritious, economically important, and delicate vegetables grown in the world. It is highly susceptible to insect pests and microbial pathogens. The tomato leafminer moth, Tuta absoluta Meyrick, is the current impediment to tomato production in the world. The insect showed invasive and notorious behavior and was affecting tomato production. To control this insect, the application of synthetic insecticides is seen as the primary solution. However, during the feeding stage, larvae hide within mined leaf mesophyll and bored fruits from chemical spray, besides fast developing resistance to several insecticides. Such characteristics of the insect reduced the effectiveness of the chemical control efforts. Currently, the natural, or ecofriendly pest control method is gaining the momentum to minimize the application of synthetic insecticide against this devastating insect. Studies showed that botanical extracts (phytochemicals) and natural enemies such as parasitoids, predators, entomopathogenic nematodes, entomopathogenic fungi, and entomopathogenic bacteria are effective for controlling T. absoluta. As a result, the basic attributes of the above-mentioned natural agents and their potential to control T. absoluta have been briefly discussed in this review. However, due to disease (pests), the expected outcome for the subsectors is still low. Therefore, the pinpointing of major diseases and pests and their control measures would help to significantly improve the crop production technology used by smallholder farmers and thereby sustainably improve tomato production in Ethiopia.
