Opis:: Beauveria bassiana is an entomopathogenic fungus that is widely used in Thailand to control pest insects. However, the increasing temperature has influenced the insect control efficiency of the fungus. Therefore, determination of thermotolerant isolates of B. bassiana that can grow and remain pathogenic at higher temperatures than its current optimum temperature may be a better way to control pest insects in a high temperature environment. Three isolates of B. bassiana obtained from the Rice Department, Thailand were selected for mutagenesis using ethyl methanesulfonate (EMS) with subsequent screening at high temperatures (33 and 35°C). In addition, the recovery of fungal growth after exposure to a high temperature for a period of time (5–15 days) and then transferring to 25°C was evaluated. No isolates were found that grew at 35°C but one mutant isolate (BCNT002MT) produced larger diameter colonies and more spores than the corresponding wild type (WT) at 33°C. Growth and spore production of the BCNT002MT isolate were greater than its WT when incubated at 25°C for 14 days following exposure to 33°C for 7 days. In addition, the spore germination level (%) of BCNT002MT was significantly higher than its WT during culture at 25°C after prior exposure to 33°C for 5, 10 and 15 days. The pathogenicity against the brown planthopper, Nilaparvata lugens (Stål), of this mutant isolate was also prominent.

Opis:: We carried out an experiment with using the entomopathogenic fungus Beauveria bassiana (Bals.) Vuill. for sanitation of active infested trees. We used 15 active infested trees from which 5 stems were treated with an insecticide, 5 were treated with solution of the tested entomopathogenic fungus and 5 were left as control. The used insecticide was pyretroid Fury 10 EW. We used a biopreparation based on the entomopathogenic fungus B. bassiana in form of wettable powder. The material was diluted. The suspension contained 107spores of the tested entomopathogenic fungus in 1 ml. The suspension was applied across the whole stem surface. We succeeded to infect about 28.75% of Ips typographus L. individuals in the treated stems. The number of live individuals was comparable with the variant using the insecticide.

Opis:: The Brazilian poplar moth is the most important pest of poplar plantations in Brazil. This research evaluated the effect of Beauveria bassiana Bals. (Vuill.) on the mortality and development of Condylorrhiza vestigialis Guen. (Lepidoptera: Crambidae). The aim was to develop alternative methods for management of this pest. The pathogens were sprayed on poplar leaves and consequently, the pathogens reached the caterpillars. Bacillus thuringiensis var. kurstaki Berliner was sprayed as the standard treatment. The spray for the control was distilled water. Both pathogens B. bassiana and B. thuringiensis affected insect development with increase mortality at each stage of the insect cycle, reaching a satisfactory control level. Microbial control of Brazilian poplar moth with B. bassiana is promising. Tests with other strains and species of pathogens, mainly under field conditions, were also encouraging. This is the first report about the action of B. bassiana against C. vestigialis.

Opis:: Although pear is one of the most preferred fruits globally due to its high nutrient content, its juice products have not received equal consumer acceptability due to their undesirable haziness and turbidity. However, enzymatic treatment of juice has been noted to improve the overall acceptability of juices better than traditional decantation, filtration, and heating methods, which are either expensive or detrimental to the product quality. In this study, pear juice was effectively clarified using partially purified polygalacturonase from an entomopathogenic fungal endophyte Beauveria bassiana SAN01. The optimization of the juice clarification process led to 137% improvement in clarification compared to control, under optimal conditions of 39.37 U/mL enzyme load, 36.87°C temperature and 2.75 h treatment time. Results also showed that the polygalacturonase treatment resulted in a significant decrease in viscosity and an increase in the pseudoplasticity of the pear juice as the rheological data of the juice was observed to fit adequately into the power law model (R2>0.9). Furthermore, the enzyme-assisted juice clarification was found to reduce browning index (-14.34%) and turbidity (-19.72%) while increasing the reducing sugar content (9.55%). Unlike some conventional juice treatments, the polygalacturonase treatment preserved the antioxidant potential and the total phenolic contents of the pear juice as no significant changes were observed after the treatment. This study thus demonstrates the efficacy of a fungal polygalacturonase in improving pear juice quality as well as the potential applicability of B. bassiana enzymes in the food industry.

Opis:: The effect of three pesticides used in corn protection: Targa Super 05 (chizalofop-P-ethyl), Roundup 360SL (glyphosate) and Karate Zeon 050CS (lambda-cyhalothrin), on the growth of entomopathogenic fungi Hirsutella nodulosa Petch and Beauveria bassiana (Bals.) Vuill. was evaluated under laboratory conditions. Fungi isolates were cultured on Sabouraud’s medium with addition of pesticides at three different concentrations. H. nodulosa was more susceptible to pesticides than B. bassiana. The most inhibitory effect on tested entomopathogenic fungi showed chizalofop-P-ethyl herbicide. Lambda-cyhalothrin at the recommended field dose showed minor toxic effect on entomopathogenic fungi, which suggests the possibility of compatible use of this insecticide with biopesticides based on the tested species.

Opis:: Laboratory bioassays were conducted to assess the insecticidal efficacy of the formulation SilicoSec® used alone or in combination with isolates of entomopathogenic fungi, Metarhizium anisopliae (Metschinkoff) Sorokin and Beauveria bassiana (Balsamo) Vuillemin. SilicoSec® is a commercial diatomaceous earth (DE) formulation. Wheat was treated with 200 mg/kg of DE, 400 mg/kg of each isolates alone or a combination of them, against Tribolium castaneum Herbst, Rhyzopertha dominica (F.), and Oryzaephilus surinamensis L. The experiments were carried out at 27±1°C and 65±5% relative humidity (RH) in continuous darkness. The pathogenicity of all isolates was significantly low even after 7 days of exposure, with the exception of R. dominica. The isolates were virulent to the beetles, but the efficacy of the isolates was enhanced in combination with the DE. Tribolium castaneum was the most resistant species, followed by R. dominica. The findings indicated that the addition of the DE to the isolates increased the pathogenicity especially at the highest exposure interval. The addition of DE may provide satisfactory control of the insect-pests of stored products.

Opis:: Bollworms comprise the most harmful and economically relevant species of lepidopteran. Helicoverpa gelotopoeon (D.) (Lepidoptera: Noctuidae) is native to America and affects many crops. Tobacco is an industrial crop in which methods of pest control rely mainly on the application of insecticides. To develop new eco-friendly strategies against insect pests it is very important to overcome the side effects of insecticides. The utilization of fungal entomopathogens as endophytes is a new perspective that may accomplish good results. The present study aimed to evaluate the ability of endophytic Beauveria bassiana (Bals.-Criv.) Vuill. to affect H. gelotopoeon life parameters and feeding behavior on tobacco plants. Beauveria bassiana LPSC 1215 as an endophyte did not reduce the amount of vegetal material consumed by H. gelotopoeon larvae but affected the life cycle period of the plague, particularly the larval and adult stages. Also, egg fertility was affected since adults laid eggs that were not able to hatch. The results of this investigation provide new information on endophytic entomopathogen potential to be incorporated in Integrated Pest Management (IPM) programs.

Opis:: We evaluated the efficacy of four different methods for endophytic inoculation of entomopathogenic fungus Beauveria bassiana in tomato plants. Fourteen days after inoculation, root dipping and leaf spraying allowed recovery of B. bassiana from leaves, while the fungus was recovered from roots in all inoculation methods, except soil drenching. Significant increases in mortalities of nymphs and adults of the greenhouse whitefly, 36 to 52%, were recorded on B. bassiana-endophyt plants. The total phenolic and protein contents of tomato plants were increased by endophyte colonization. Results of this study confirm the efficiency of foliar spraying of B. bassiana for colonization in tomato plants and its insecticidal activity against whitefly. The persistence of B. bassiana as endophyte was confirmed up to 56 days after inoculation. Given the insecticidal activity and beneficial effects of the endophyte on plant growth, B. bassiana could be considered as a suitable element in integrated pest management.
Oceniliśmy skuteczność czterech różnych metod endofitycznej inokulacji entomopatogennego grzyba Beauveria bassiana do pomidorów. 14 dni po zaszczepieniu stwierdzono obecność B. bassiana w liściach w przypadku inokulacji poprzez zanurzanie korzeni i oprysk liści, natomiast obecność grzyba w korzeniach stwierdzono przy wszystkich metodach inokulacji, z wyjątkiem zwilżania gleby. Na pomidorach zainfekowanych B. bassiana odnotowano znaczny wzrost śmiertelności nimf i osobników dorosłych mączlika szklarniowego, wynoszący od 36 do 52%. Całkowita zawartość fenoli i białka w tkankach pomidora wzrosła w wyniku kolonizacji endofitów. Wyniki badań potwierdzają skuteczność oprysku dolistnego B. bassiana w kolonizacji pomidora i jego owadobójcze działanie na mączlika szklarniowego. Trwałość B. bassiana jako endofitu została potwierdzona do 56 dni po inokulacji. Biorąc pod uwagę aktywność owadobójczą i korzystny wpływ endofitu na wzrost roślin, B. bassiana można uznać za odpowiedni element zintegrowanej ochrony roślin przed szkodnikami.

Opis:: The inducible metalloproteinase inhibitor (IMPI) discovered in Galleria mellonella is currently the only specific inhibitor of metalloproteinases found in animals. Its role is to inhibit the activity of metalloproteinases secreted by pathogenic organisms as virulence factors to degrade immune-relevant polypeptides of the infected host. This is a good example of an evolutionary arms race between the insect hosts and their natural pathogens. In this report, we analyze the expression of a gene encoding an inducible metalloproteinase inhibitor (IMPI) in fat bodies of the greater wax moth larvae Galleria mellonella infected with an entomopathogenic fungus Beauveria bassiana. We have used a natural infection, i.e. covering larval integument with fungal aerospores, as well as injection of fungal blastospores directly into the larval hemocel. We compare the expression of IMPI with the expression of genes encoding proteins with fungicidal activity, gallerimycin and galiomycin, whose expression reflects the stimulation of Galleria mellonella defense mechanisms. Also, gene expression is analyzed in the light of survival of animals after spore injection.

Opis:: Five morphological types of hemocytes were recognized in hemolymph of the 4th instar larvae of Hyphantria cunea (Drury). These hemocytes were: prohemocytes, plasmotocytes, granulocytes, oenocytoids, and spherulocytes. Tests were done on the effects of four isolates of the entomopathogenic fungus Beauveria bassiana (Bals.-Criy) (Fashand, spt-22, Ir-K-40 and 566), one isolate of Isaria farinosae (Holmsk.) Fr. (1872c), and latex-beads on the cellular immune defense mechanism and Phenoloxidase (PO) activity of H. cunea. Observation showed that plasmatocytes and granulocytes engulfed fungal pathogens by phagocytosis. The most phagocytosis occurred 30 and 60 min after injection but nodulation occurred in 3 and 6 hours, in all treatments. The total hemocyte count (THC) and granulocyte, and plasmotocyte numbers increased after the injection of spores. Phenoloxidase activity was determined in the presence of L-DOPA (L-3,4-dihydroxyphenylalanine), as a substrate in intervals, after injection of fungal spores, and latex beads. These studies demonstrated that B. bassiana is a promising candidate for biological control of H. cunea.

Opis:: Aphids (Hemiptera: Aphididae) are serious pests of crops causing direct damage by feeding and indirect by the transmission of plant viruses. The use of conventional insecticides for controlling aphids has caused different problems and insecticide resistance. Accordingly, there is more interest in alternative control methods such as biological control by natural enemies for sustainable agricultural management. Among biological control agents, entomopathogenic fungi are one of the most significant microbial pathogens of insects. Also, Coccinellidae, as a major group, is a serious natural enemy. Both larval and adult stages of Coccinellidae feed on different soft-body pests, such as aphids. Eriopis connexa (Germar) (Coleoptera: Coccinellidae) is a common species in agroecosystems of the Neotropical region where it is considered to be a potential control agent. Pathogens and arthropod natural enemies may contribute to the control of phytophagous pests; however, it is important to assess potential interactions within biological control agents that share hosts (intraguild interaction) to evaluate their combined use for pest control. Therefore, the aim of this study was to evaluate the compatibility and interaction (lethal and sublethal effects) between E. connexa and the entomopathogenic fungus Beauveria bassiana (Bals.-Criv.) Vuill. (Ascomycota: Hypocreales). Both are important biological control agents of aphids. The pathogenicity of B. bassiana against larvae, pupae and adults of the predator E. connexa was evaluated, and results showed, that B. bassiana infected the coleopteran. On the other hand, interaction between B. bassiana and the predator was evaluated through infected-prey. The effects of fungus on larvae survival were significantly different when we analyzed the accumulated survival (from first larval instar to adulthood). The daily fecundity was significantly reduced at five days compared to control group. By contrast, no significant differences were observed between the five oviposition days in the rate of hatched eggs. This study shows that despite having received a single dose of the fungus in its life cycle, the population parameters of the predator E. connexa are affected. More studies would be necessary to help identify interactions between microbes and natural enemies to increase and enhance opportunities and further develop biological pest control programs.

Opis:: In this in vitro study, the influence of tin ions at concentrations of 1–1,000 ppm on the development and enzymatic activity of four entomopathogenic fungi (Beauveria bassiana, B. brongniartii, Isaria fumosorosea, and Metarhizium robertsii), that are commonly used in biological plant protection, are examined. Each of the fungal species tested reacted differently to contact with the Sn2+ ions at the tested concentrations. Exposure to Sn2+ ions affected the rate of development, morphology, and enzymatic activity of fungi. Of the four fungal species studied, M. robertsii was the most resistant and showed complete growth inhibition at the highest Sn2+ concentration tested (1,000 ppm). For the other entomopathogenic fungi, the fungicidal effect of Sn2+ ions was noted at the concentration of 750 ppm. Exposure to Sn2+ ions (up to 500 ppm) resulted in enhanced biochemical activity; and all entomopathogens that were tested showed increased production of N-acetyl-β-glucosaminidase (NAG) as well as several proteases. Moreover, B. brongniartii and M. roberstii showed increased lipases synthesis. These changes may increase the pathogenicity of the fungi, thereby making them more effective in limiting the population of pest insects. The exposure of the entomopathogenic fungi to a medium containing Sn2+ ions, at concentrations that were appropriate for each species, induced hyperproduction of hydrolases, which might be involved in aiding the survival of entomopathogenic fungi in the presence of heavy metals. This study shows that the fungistatic effect of Sn2+ on entomopathogenic fungi did not restrict their pathogenicity, as evidenced by the stimulation of the production of enzymes that are involved in the infection of insects.
