“…Alterations of the length of the Trichogramma parasitoids' egg-to-adult period may be related to changes in the host caused by the fungus [38]. However, the near absence of alterations in the egg-to-adult period reinforces prior test findings that D. fovealis eggs were not affected by EF [21].…”

“…Subsequent spray applications of two B. bassiana strains that were isolated from Coleoptera species present in strawberry crops caused high mortality among D. fovealis larvae (>60%) [ 20 ]. Recent research on B. bassiana infections of D. fovealis has shown that although the fungus effectively controlled larvae and pupae, it did not affect the eggs [ 21 ]. Indeed, eggs are considered to be the most difficult insect life stage to kill because of their protective structure, which provides a barrier against penetration by insecticides and pathogens [ 22 , 23 , 24 ].…”

The European pepper moth, Duponchelia fovealis (Lepidoptera: Crambidae), is a key pest in strawberry production. Entomopathogenic fungi (EF) and parasitoids of the Trichogrammatidae family are effective biological control agents of this pest with the potential to be used jointly for improved efficacy. This study aims to evaluate the susceptibility of Trichogramma atopovirilia and Trichogramma pretiosum to two Beauveria bassiana strains (B2 and B3) and two commercial bioinsecticides (Bovemax® and Methamax®) by applying them to D. fovealis eggs in pre- and post-parasitism periods. Pre-parasitism application of B2 and B3 did not affect the percentage of D. fovealis eggs parasitized by either Trichogramma species, except in the case of T. atopovirilia when eggs were sprayed with B3 at 1.5 × 105 conidia mL−1 (16.7% less than the control). In contrast, eggs sprayed with 1.5 × 108 conidia mL−1 of the commercial bioinsecticides were not parasitized by any Trichogramma species. Overall, the EF tested reduced the parasitism rate, adult emergence, and longevity of Trichogramma adults by less than 30% in all cases. The adverse effects of the B. bassiana strains and commercial products on the biological traits of both Trichogramma species were minimal, meaning that these agents can be used jointly in D. fovealis control strategies.

“…In this study, isolate (DM-3) was identified as C. javanica, which is a well-known insectpathogen that has been extensively used to control a wide range of insect hosts [48][49][50]. In support of our results, C. javanica isolated from Korean soils using G. mellonella entrapment was reported to have dual biocontrol potential against the green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae) and against both the fungal and oomycete pathogens Colletotrichum gloeosporioides and Phytophthora capsici, respectively [51].…”

The compound negative impact of insect pests attacking agricultural ecosystems includes (i) direct yield losses from damaged crops, (ii) the economic cost of the attempt to prevent these losses and (iii) the negative short- and long-term hazard effects of chemical pesticides on human and environmental health. Entomopathogenic fungi (EMPF) are a group of microorganisms that represent the natural enemies of a number of crop pests, presenting an opportunity to harness their evolutionary fine-tuned relationship with their insect hosts as biocontrol agents in integrated pest management programs. The aim of this study was to establish an indigenous EMPF collection via the Galleria mellonella (greater wax moth) entrapment method from the soils of Nile Delta, Egypt. Obtained insect associated fungal isolates were bio-assayed for pathogenicity against the serious pest Spodoptera litura and Tenebrio molitor, and the seven outperforming isolates were selected for molecular identification and thermotolerance assay. Based on ITS sequence analysis and phylogeny, selected isolates were identified as Beauveria bassiana (four isolates), Metarhizium anisopliae (two isolates) and one isolate of Cordyceps javanica. The obtained results demonstrated (i) the efficacy of using insect baiting coupled with molecular identification and pathogenicity screening to isolate EMPF to control insect pests, and (ii) the availability of indigenous virulent EMPF in Nile Delta’s soil, which can be exploited for the development of sustainable crop protection strategies.

“…Currently, no authorized biological or chemical pesticides for controlling L. bilineata are available in Brazil. The damage caused by this coleoptera on P. peruviana and the absence of commercial pesticides have led producers and agricultural technicians to seek alternatives [8], which include biological controls [4,9]. In this regard, the search in the wild for natural enemies, such as parasitoids, predators, and entomopathogenic fungi, associated with this coleoptera pest species is crucial for guiding new research on organisms with the potential to be used in conservation biological control strategies or applied biological control programs [4,10,11].…”

“…A highly diverse range of entomopathogenic fungi can be naturally present in agroecosystems, acting as regulators of arthropod pest populations [12,13]. However, due to the high biodiversity of these organisms, it is important to know the pathogenicity and degree of virulence of a given fungal strain against a specific pest [9,14].…”

Lema bilineata Germar (Coleoptera: Chrysomelidae) was recently reported to damage Physalis peruviana crops in Brazil. Given the potential for inflicting damage on other Solanaceae species and the lack of alternatives for controlling this pest, we assessed the pathogenicity of 15 Beauveria isolates against L. bilineata adults in vitro. In addition, three of these isolates were tested for their ovicidal effect against L. bilineata eggs. Fungal strains were isolated from mummified corpses of L. bilineata collected in a non-commercial field in Paraná, Brazil. The isolates were identified as Beauveria bassiana using molecular markers. Lema bilineata adults were susceptible to conidial suspensions of all these isolates at a concentration of 108 conidia mL−1. Deaths caused by fungal extrusion were confirmed. Three strains were found to be more virulent against L. bilineata adults and showed ovicidal effects. This is the first study on entomopathogenic fungi isolated from dead insects collected from P. peruviana crops and tested against L. bilineata carried out in Brazil. The results obtained in the laboratory indicate the high potential of the use of three B. bassiana strains against L. bilineata as a biocontrol agent.
