Neotropical Entomology 36(2): 161-179 (2007) Controle Microbiano de Artrópodes-Praga em Fruteiras Tropicais RESUMO -Muitos insetos e ácaros atacam fruteiras nos trópicos. O método tradicional para controlar a maioria dessas pragas é a aplicação de inseticidas químicos. A crescente preocupação sobre os efeitos negativos desses produtos vem encorajando o desenvolvimento de alternativas. Agentes do controle biológico aplicados de forma inundativa ou inoculativa têm sido pesquisados como método de controle alternativo para uma variedade de pragas em grande número de culturas, incluindo fruteiras tropicais. A maioria das pesquisas e aplicações em fruteiras tropicais tem sido feita em citros, insetos. Em banana, o controle do moleque-da-bananeira, Cosmopolites sordidus Germar (Coleoptera: Curculionidae) com nematóides e fungus também é considerado de sucesso. Oryctes rhinoceros (L.) (Coleoptera: Scarabaeidae) é uma das principais pragas em côco e um dos mais importantes exemplos de controle biológico clássico por vírus não-ocluso. As pragas-chave em manga que têm sido controladas com diferentes agentes de controle microbiano são as moscas-das-frutas (Diptera: Tephritidae), com nematóides e fungos, o gorgulho-da-manga, Sternochetus mangiferae (Fabricius) (Coleoptera: Curculionidae), com fungos, e vários hemípteros com fungo. O controle microbiano de a maior aplicabilidade dessas tecnologias é o desenvolvimento de combinações compatíveis entre entomopatógenos, predadores e parasitóides juntamente com outras técnicas de controle. PALAVRAS-CHAVE: Bactéria, vírus, fungo, nematóideABSTRACT -A multitude of insects and mites attack fruit crops throughout the tropics. The traditional method for controlling most of these pests is the application of chemical pesticides. Growing concern on the negative environmental effects has encouraged the development of alternatives. Inundatively and inoculatively applied microbial control agents (virus, bacteria, fungi, and entomopathogenic nematodes) have been developed as alternative control methods of a wide variety of arthropods including tropical fruit pests. The majority of the research and applications in tropical fruit agroecosystems has been conducted in citrus, banana, coconut, and mango. Successful microbial control initiatives of citrus pests and mites have been reported. Microbial control of arthropod pests of banana includes banana weevil, Cosmopolites sordidus Germar (Coleoptera: Curculionidae) (with EPNs and fungi) among others Oryctes rhinoceros (L.) is one of the most important pests of coconut and one of the most successful uses of non-occluded virus for classical biological control. Key pests of mango that have fungi), and other pests. Also successful is the microbial control of arthropod pests of guava, papaya and pineapple. The challenge towards a broader application of entomopathogens is the development of successful combinations of entomopathogens, predators, and parasitoids along with other interventions to produce effective and sustainable pest management.

“…Fries (=Paecilomyces farinosus), Hirsutella thompsonii Fisher, and Neozygites floridana Weiser and Muma often play an important role in decreasing native populations of phytophagous mites (Chandler et al, 2000;Van der Geest et al, 2000). Searching for microbial control agents in laboratory experiments it has been shown that some of the tested isolates of B. bassiana and M. anisopliae are highly virulent to the active stages of T. urticae (Alves et al, 2002a;Tamai et al, 2002;Chandler et al, 2005) and T. evansi Baker and Pritchard (Wekesa et al, 2005). According to Feng (2006, 2009) some of the tested isolates of B. bassiana, Paecilomyces fumosoroseus (Wize) Brown and Smith and M. anisopliae have high lethal effect on eggs and females of T. urticae.…”

SUMMARYBioassays with five isolates of the entomopathogenic fungus Beauveria bassiana (Bals.-Criv.) Vuillemin were conducted under laboratory conditions with a goal to estimate their virulence to the two-spotted spider mite Tetranychus urticae Koch. (Acari: Tetranychidae). Common bean plants with mites were treated by spraying conidial suspensions of isolates at concentrations of 10 6 , 10 7 and 10 8 conidia/ml. Lethal effects of the fungal isolates were evaluated as percentages of cumulative daily mortality due to mycoses, corrected for mortality in the control variant. Virulence of the isolates was estimated based on values of the median lethal time (LT 50 ) calculated by probit analysis for the variants treated with conidial suspensions at the concentration of 10 6 conidia/ml.The two-spotted spider mite was found susceptible to the examined isolates of the entomopathogenic fungus B. bassiana.Mycosis caused to T. urticae by the B. bassiana isolates 444 Bb and 445 Bb had fast lethal effect after treatment with conidial suspensions even at the concentration of 10 6 conidia/ ml. The mean mortality values of host individuals were 83.78 ± 3.62% and 68.49 ± 4.28% on the first day, respectively, and up to 100% in both variants on the fourth day.The isolates 426 Bb, 444 Bb and 445 Bb of B. bassiana were highly virulent to two-spotted spider mites with values of the median lethal time varied within overlapped narrow confidence intervals from 0.122 to 1.084 days (average value 0.162 days), from 0.117 to 1.398 days (average value 0.146 days) and from 0.106 to 1.162 days (average value 0.131 days), respectively. Significant differences regarding virulence of the three isolates at p-level < 0.05 could not been proved. The other two examined isolates were distinctly less virulent to T. urticae than these three B. bassiana isolates.

“…This species is the most widely used one available commercially all over the world (Goettel et al, 2005). Products based on this species are available for use against a very wide variety of insect pests, from banana weevils [Cosmopolites sordidus (Germar, 1824)] in Brazil (Alves et al, 2003) to pine caterpillars (Dendrolimus spp.) in China (Feng et al, 1994).…”

The willow leaf beetle, Plagiodera versicolora (Laicharting, 1781), is one of the most destructive pests of many Salix and Populus species worldwide. A total of 12 entomopathogenic fungi including Beauveria bassiana (Bals.) Vuill., B. cf. bassiana, Metarhizium anisopliae (Metch) Sorok, and Isaria fumosorosea (Wize) (formerly Paecilomyces fumosoroseus) were tested against the larvae of this pest under laboratory conditions in order to find any possible fungal biocontrol agent against it. A conidial concentration of 1 × 10 7 conidia ml -1 for each isolate was applied to third instar larvae of the pest. Among tested fungal isolates, the highest mortality was obtained as 100% from B. bassiana KTU-57 within 14 days after inoculation (p < 0.05). This isolate also caused the highest mycosis value (83%) (p < 0.05). It was selected for dose-response test according to the screening test, and lethal concentration at 50% (LC 50 ) value of the fungus on the larvae of the pest was calculated as 1.03 × 10 5 conidia ml -1 based on probit analysis. Consequently, B. bassiana KTU-57 appears to be a significant promising isolate against the willow leaf beetle as a possible biocontrol agent.
