Opis:
The epidemiological and epizootic importance of ticks has been known for a few decades since of the discovery of their role as vectors of many new diseases, and the better detection of those already known. Given the durability of chemical preparations in the environment and the increasing problem of developing tick resistance, natural strategies for biological control are sought. A promising alternative to chemical pesticides is the use of entomopathogenic organisms for effective integrated pest management of low environmental impact. A number of promising microbes have been identified during the search for effective means of controlling the tick population, but the knowledge about the impact of these pathogens on the environment and other non-target organisms is still insufficient. Previous research has still not provided a definite answer about the safety of their use. It is known, however, that the chemicals which are currently used have a negative impact on the environment and/or cause resistance. No efficient biocompound has yet been devised for commercial use. Potential microorganisms for tick biocontrol (mainly bacteria and fungi) are natural tick pathogens, living in the same environment. With their adhesive properties, and their ability to digest the cuticle, they may constitute an appropriate ingredient of bioacaricides. Until now, fungal insecticides have been used only to control crop pests.

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:
The paper presents results of various experiments on the use of entomopathogenic fungi (e.g. Beauveria bassiana, B. brongniartii, Metarhizium anisopliae, Lecanicllium spp.) to control leaf feeding insects (Lymantria spp., Dendrolimus pini, Cephalcia abietis, Diprionidae) and insects feeding on bark and cambium (Hylobius spp., Scolytinae)

Opis:
Pleśniakowiec lśniący (Alphitobius diaperinus) Panzer występuje w dużych liczebnościach w brojlerniach. Owady te są szczególnie niebezpieczne jako potencjalne nośniki patogenów, takich jak bakterie, wirusy i pasożyty. Badania dotyczyły możliwości wykorzystania lokalnych szczepów grzybów entomopatogennych izolowanych ze ściółki i gleby do ograniczania populacji tego owada. Izolowane grzyby wykazywały niską patogeniczność w stosunku do chrząszczy owada. Po infekcji zawiesiną w stężeniu 1 × 108 zarodników/ml tylko 4 izolaty Metarhizium anisopliae sensu lato wykazywały najwyższą śmiertelność owadów w zakresie 30–36%. Jeszcze mniejszą patogeniczność w stosunku do chrząszczy owada wykazywały izolaty Beauveria bassiana, tylko 4 z nich powodowały śmiertelność w zakresie 17–26%. Izolaty Isaria fumosorosea i I. farinosa powodowały śmiertelność chrząszczy na poziomie wariantu kontrolnego. Larwy były bardziej podatne na infekcję. Z wyjątkiem I. fumosorosea wszystkie badane gatunki grzybów powodowały 100% śmiertelność larw. Do dalszych badań można wyselekcjonować izolat B. bassiana 3K (ze ściółki) ze względu na wysoką śmiertelność (100%) i wysoką infekcyjność larw (50% porośniętych grzybnią).
The lesser mealworm Alphitobius diaperinus is present in great numbers in poultry houses. These insects are especially dangerous as a potential carriers of pathogens such as bacteria, viruses and parasites. We explored the possibility of using local strains of entomopathogenic fungi isolated from litter and from soil to control lesser mealworm populations. Isolated fungi showed low pathogenicity to lesser mealworm beetles. Infection with a suspension at a concentration of 1 × 108 spores/ml resulted in only 4 Metarhizium anisopliae sensu lato isolates showing the highest insect mortality in the range of 30–36%. Still lower pathogenicity was found in isolates of Beauveria bassiana, with only 4 isolates of B. bassiana causing a mortality of 17–26%. Isolates of Isaria fumosorosea and I. farinosa did not cause mortality in beetles that differed significantly from that in the control variant. The larvae were more susceptible to infection. Except for I. fumosorosea, all species caused 100% mortality in larvae. For further studies, the B. bassiana 3K isolate (from the litter) could be selected because of its high mortality (100%) and high larval infectivity (50% overgrown with mycelium).
