Opis:: The effects of pyriproxyfen were determined on the cellular immunity and phenoloxidase activity in the 4th instar larvae of Chilo suppressalis Walker. The bioassay results revealed the effective concentrations of: 10L : 18C, 30L : 72C and 50L : 190C μg · ml–1. The sole effect of 18 and 72 μg · ml–1 concentrations at intervals of 1–3 h caused a higher number of total hemocytes in the treated larvae than the control, but the reverse results were observed after 6–24 h. The number of plasmatocytes was lower than that of the control for intervals of 3–24 h but the number of granulocytes was higher than the control after 1–3 h although no significant differences were observed at the other times. In the treated larvae, the activities of phenoloxidase were higher and lower than those of the control after 1–3 h and 6–24 h, respectively. The combined effects of pyriproxyfen and the entomopathogenic fungus, Beauveria bassiana isolate B3 caused higher numbers of total hemocytes, plasmatocytes, and granulocytes in the treated larvae by use of the three concentrations of pyriproxyfen, at intervals of 6 and 12 h. Although the numbers of nodules in the larvae treated with concentrations of 18 μg · ml–1 were higher than those of other treatments, the overall numbers were lower than those of the control. Finally, the activity of phenoloxidase in the treated larvae was higher than that of the control, at intervals of 6 and 12 h post-treatment. Findings of the current study indicate an intervening role of pyriproxyfen in the cellular immunity of C. suppressalis to entomopathogenic objects.

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:: 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:: Fungal entomopathogens can naturally regulate populations of various insects. The entomopathogen Beauveria bassiana (Bals.- Criv.) Vuill. is also able to endophytically colonize different plants. Endophytic colonization by entomopathogens may provide a source of indirect interactions between fungi and insects and has been associated with the ability of the fungus to control insect pests. The tomato leaf miner, Tuta absoluta (Meyrick) is considered one of the most devastating pests of tomato (Solanum lycopersicum L.) and its difficult control is due to its miner habit, short life cycle, and high reproductive capacity. The aims of this study were: (i) to use three different techniques, i.e. leaf spraying, seed immersion and root dipping, for the endophytic inoculation of B. bassiana in tomato plants; and (ii) to assess the effect of B. bassiana on tomato leaf consumption and mortality of T. absoluta after inoculation. The percentage of colonization by B. bassiana was assessed 7, 14 and 28 days after inoculation. All inoculation techniques employed allowed the recovery of B. bassiana, although our results showed significant differences between techniques. Leaf spraying was the most effective, with the highest percentage of colonization recorded 7 days after inoculation. We also evaluated (i) the effect on the mortality of T. absoluta by direct contact with conidia of B. bassiana, and (ii) the effect on tomato leaf consumption and mortality by indirect contact through ingestion of inoculated plant tissues with B. bassiana. Mortality bioassays showed that B. bassiana infected T. absoluta, either by direct contact or indirectly, via ingestion of inoculated tomato leaves. Direct contact showed a higher percentage of mortality and a lower median survival time (MST) than indirect contact. Significant differences in the mortality percentages of T. absoluta after exposure with B. bassiana were found among the treatments and the control. Our results suggest that the endophytic inoculation of B. bassiana in tomato crops provides the basis for further investigation, which should focus on the virulence of the endophytic B. bassiana against T. absoluta.

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:: Interest in growing roses in Poland is related to the production of cut flowers as ornamentals and of petals and hips for cosmetics or food products. However, recently there has been an increasing number of reports of pest damage on rose plantations. In the case of fruits the damage has been attributed to flies (Rhagoletis alternata) or moths (Cydia tenebrosana), while nematodes have been implicated for growth reduction even on plantations grown under soil-less conditions. Field trials and laboratory experiments to test the possibility of controlling R. alternata larvae or pupae with entomopathogenic fungi and nematodes resulted in a lack of parasitism. On the other hand, the use of Bacillus thuringiensis subsp. kurstaki or Cydia pomonella granulovirus effectively controlled C. tenebrosana. Meloidogyne incognita infestation of roses growing on rock wool substrate was drastically reduced by Arthrobothrys oligospora or abamectin. Factors such as the method of product application or pest susceptibility to the used microbial-based products accounted for the observed differences in efficacy.

Beauveria bassiana
Opis:: Grzyby owadobójcze z łatwością porażają larwalne stadia rozwojowe owadów żerujące w glebie oraz te, które schodzą do gleby w celu przepoczwarczenia czy przezimowania. Wirulencja tych grzybów może być z powodzeniem wykorzystana w biologicznej walce ze szkodnikami ziemniaka. Zapewnienie odpowiedniego siedliska patogenom w pobliżu pól uprawnych zwiększa szanse wystąpienia maso- wych chorób szkodników w warunkach naturalnych. Na bazie rodzimych szczepów powstają komer- cyjne preparaty stosowane w integrowanej ochronie roślin oraz uprawie ekologicznej.

Opis:: The soil is a habitat for many entomopathogenic fungi (EPF) all over the world. The Galleria bait method has been chosen to isolate the EPF from soil samples. The common occurrence of EPF in agricultural land was confirmed by these studies, which concluded, that the soil of Cape Verde is a habitat for EPF, such as Beauveria bassiana and Metarhizium anisopliae. The presence of B. bassiana was recorded in the cultivable land of the island of Fogo, while M. anisopliae occurred in the soil of Fogo as well as Santiago. There were no records of EPF in woodlands. Statistically, more soil samples containing B. bassiana were derived from perennial crops. The amount of sand in the soil determined the presence of the fungus. On the other hand, M. anisopliae was present on less inclined grounds. Fusarium spp. was present in half of the examined soil samples. The isolation of native EPF and their subsequent application in developing countries may significantly contribute to reduce pest populations in agriculture effectively.
Występowanie grzybów owadobójczych w glebach wysp Santiago i Fogo (Republika Zielonego Przylądka). Gleba jest siedliskiem wielu grzybów owadobójczych (EPF) na całym świecie. Do izolowania EPF z prób glebowych zastosowano metodę owadów pułapkowych. Powszechność występowania EPF na terenach rolnych została potwierdzona niniejszymi badaniami, w wyniku których stwierdzono, że gleby Republiki Zielonego Przylądka są siedliskiem EPF, takich jak Beauveria bassiana i Metarhizium anisopliae. Obecność B. bassiana zarejestrowano w glebie wyspy Fogo a występowanie M. anisopliae zarówno na wyspie Fogo, jak i Santiago. Nie stwierdzono EPF na terenach zalesionych. Statystycznie więcej prób glebowych zawierających B. bassiana pochodziło z terenów pokrytych uprawami roślin wieloletnich, przy czym istotnym czynnikiem wpływającym na obecność grzyba była zawartość piasku w glebie. M. anisopliae był natomiast obecny na terenach o mniejszym nachyleniu terenu. Fusarium spp. był obecny w połowie przebadanych prób glebowych. Izolowanie EPF rodzimych z późniejszym ich zastosowaniem w krajach rozwijających się może w istotny sposób przyczynić się do skutecznego ograniczenia liczebności populacji szkodników w uprawach.
