“…This study also showed that C. javanica is host-specific and virulent to some groups of insects. C. javanica is the most prevalent fungi attacking whiteflies worldwide (Lacey et al 1993, 1996, Humber 2000, Faria & Wraight 2001, Quintela et al 2016, Boaventura et al 2021), but showed a median virulence to stink bugs and cotton boll weevil.…”

“…The two strains of Cordyceps javanica BRM 14526 and BRM 27666 were isolated from insects at epizootic conditions and showed a high virulence to the whitefly Bemisia tabaci (Mascarin et al 2018, Santos et al 2018, Boaventura et al 2021. The strain BRM 27666 of C. javanica was registered in August 2022 as a wettable powder named Lalguard Java for whitefly control after seven years of collaborative research between the Embrapa and Lallemand Plant Care Brazil (Patos de Minas, MG, Brazil) (Brasil 2022).…”

Entomopathogenic fungi stand out in the biological control of several agriculturally important insects. Six isolates of Metarhizium anisopliae, Cordyceps javanica, Beauveria sp. and B. bassiana were screened to control Anthonomus grandis, Euschistus heros, Oebalus poecilus, O. ypsilongriseus and Thyanta perditor, important insect pests of soybean, cotton and rice. The bioassays were conducted in a completely randomized design, with four replications (10 insects/replication). Significant differences for virulence were observed between the tested fungal species and isolates. For A. grandis, the most virulent isolate was M. anisopliae BRM 2335, followed by Beauveria BRM 14527 and BRM 67744 [82.5 to 97.5 % of mortality; average lethal time (LT50) of 5.9 to 7.8 days]. M. anisopliae BRM 2335 was also highly virulent to the four stink bug species (75 to 97.5 % of mortality; LT50 of 5.2 to 9.7 days). For the stink bugs, Beauveria sp. BRM 67744 was infectious to O. poecilus (75 % of mortality), but failed to control E. heros (16.9 % of mortality). C. javanica BRM 27666 and BRM 14526 showed average virulence to the stink bugs and A. grandis (17.5 to 57.3 % of mortality; LT50 of 6.0 to 9.7 days). M. anisopliae was consistently more virulent to the stink bugs than the other fungi. Therefore, M. anisopliae BRM 2335 was selected for further studies under screenhouse and field conditions to control A. grandis and other stink bug species, especially E. heros.

“…The mortality of G. brimblecombei nymphs, up to seven days after the application of the fungus isolates is similar to that observed for three Cordyceps sp. isolates causing mortality up to 88.6% (Boaventura et al, 2021) and C. javanica with 81% for the third instar B. tabaci nymphs (Sain et al, 2021). The mortality of insects by the fungi is related to the production of bioactive compounds, such as trichodermin, 5-methylmellein, brevianamide F, enniatin and beauvericin produced by C. fumosorosea (Wu et al, 2021) and the secondary metabolites emericellin and fumosorinone by C. javanica (Lin et al, 2019) with insecticide properties.…”

The Brazilian forestry sector stands out for its technology, forestry management practices, social and environmental responsibility and, mainly, for its high productivity and exotic pests can reduce it. The red gum lerp psyllid Glycaspis brimblecombei (Moore, 1964) (Hemiptera: Aphalaridae) is an important pest in Eucalyptus plantations. The parasitoid Psyllaephagus bliteus (Riek, 1962) (Hymenoptera: Encyrtidae), predatory bugs and entomopathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae are the natural enemies and used in the biological control of the red gum lerp psyllid. The use of entomopathogenic fungi against exotic pests is increasing in the forestry sector and the prospecting and identification of fungus isolates is important for integrated pest management. The objective of this work was the isolation and molecular identification of Cordyceps spp. And to evaluate the pathogenicity of isolates, obtained from Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) adults, against to the red gum lerp psyllid G. brimblecombei. The fungi were isolated from B. tabaci adults found in soybean and tomato crops and molecularly identified. The conidia obtained were suspended in solution with Tween 80 (0.1%) at a concentration of 1.0 × 108 conidia/mL and sprayed on ten G. brimblecombei nymphs per Eucalyptus leaf cut and placed on a hydroretentive gel inside per Petri dishes as a replication. The number of dead insects was quantified, daily, for seven days, and transferred to humid chambers. Cordyceps javanica (LCBPF 11) and C. fumosorosea (LCBPF 12 and LCBPF 63) were identified with a molecular analysis and all isolates were pathogenic to the insects and indicates that they could be used to manage G. brimblecombei and adds to reports that, normally, fungi cause greater mortality on insects of the same order as that from which they were isolated.
