Pathogens Associated with Sugarcane Borers,Diatraeaspp. (Lepidoptera: Crambidae): A Review

Abstract

The objective of this paper was to analyze information related to entomopathogenic-associated Diatraea spp. Gaining a better understanding of the effects of these microorganisms will help in the development of successful microbial control strategies against stem borers that attack sugarcane plants.

Sugarcane borers: species, distribution, damage and management options

“…Notably, among bacteria, Bt (B. thuringiensis) stands out as a well-known classical biological agent (Sanahuja et al 2011). Diverse Bt strains (HD133 cryAa, cry1Ab, cry1C; HD559; GM7 cry1Aa, cry1Ab, and cry1B; GM10 cry1Aa, cry1Ab, cry1Ac, and cry1C; GM34 cry1Aa, cry1Ab, and cry1Ac; S76 cryAa, cry1Ab, cryAc, cry2Aa, and cry2Ab) and pure proteins have demonstrated efficacy in killing D. saccharalis (Hernández-Velázquez et al 2012;Daquila et al 2021). In South Africa, novel control strategies for E. saccharina have been developed using the sugarcane endophyte Gluconacetobacter diazotrophicus carrying Bt cry1Ac genes (Theo and Gustav 2013).…”

“…In India, natural occurrences of two GVs infecting larvae of C. infuscatellus (ChinGV) and C. sacchariphagus (ChsaGV) were widely distributed in Tamil Nadu (Easwaramoorthy and Jayaraj 1987). Additionally, viruses such as Anticarsia gemmatalis MNPV (AgM-NPV), Trichoplusia ni MNPV (TnMNPV) and AgMNPV-D10 have demonstrated lethal effects on D. saccharalis (Hernández-Velázquez et al 2012). These viruses provide potential insights for practical use in the biological control of sugarcane borer.…”

“…Laboratory studies have also indicated the pathogenicity of B. bassiana against S. inferens and S. grisescens (Varma and Tandan 1996;Sweet 1994). Other entomopathogenic fungi such as Hirsutella nodulosa, Isaria tenuipes, and I. farinosa, Cordyceps species have been studied on D. saccharalis, S. inferens and C. indicus, E. saccharina (Varma and Tandan 1996;Assefa et al 2010;Hernández-Velázquez et al 2012). Moreover, Fusarium oxysporum has exhibited pathogenicity against S. inferens (Varma and Tandan 1996).…”

Evaluation of the pathogenicity of entomopathogenic fungi isolated from the larvae of the corn stem borer Diatraea grandiosella Dyar (Lepidoptera: crambidae)

“…Los hongos entomopatógenos constituyen un grupo con más de 750 especies, diseminados en el medio ambiente, provocando infecciones fungosas a poblaciones de artrópodos, por lo que tienen un gran potencial como agentes de control de plagas (Toledo et al, 2021;Cardona y Giraldo, 2015), ya que prácticamente todos los órdenes de insectos son vulnerables a las enfermedades fúngicas (Hernández et al, 2012). Muchas especies de hongos se utilizan actualmente como agentes de control biológico de plagas porque brindan una alternativa efectiva al uso de productos químicos y son amigables con el medio ambiente (Lovera et al, 2020) y en general son inofensivos para el hombre, los animales y las plantas (Zeimmermann, 2007).…”

“…(Srikanth et al, 2011), Phaecilomyces. fumosoroseus, Hirsutella sp., Cylindrocarpon sp., Isaria spp y Nomuraea rileyi (Hernández-Velázquez et al, 2012y Vejar-Cota, 2016. Bajo ciertas condiciones climáticas, se ha informado que B. bassiana causa epizootias naturales en D. grandiosella (Hernández-Velázquez et al, 2012).…”
