Corynespora cassiicola f. sp. lantanae: a potential biocontrol agent from Brazil for Lantana camara

Identification of Corynespora cassiicola causing leaf spot on Syringa species

“…There was significant variation in the susceptibility of the different host species tested (Table 2), of which S. velutina was the most susceptible to the isolates from S. oblata. In the past, C. cassiicola was generally most aggressive when inoculated onto the same host as the host of origin (Dixon et al, 2009;Maurıćio Pereira et al, 2003).…”

“…Therefore, morphological traits cannot be used as the sole criterion for characterization in C. cassiicola. In recent years, polyphasic approaches have been used to reinforce the classification of the Corynespora species, incorporating a combination of DNA-based diagnostic tools, along with morphological and physiological characterization and pathogenicity tests (Dixon et al, 2009;Maurıćio Pereira et al, 2003;Shimomoto et al, 2011;Voglmayr & Jaklitsch, 2017). We performed multilocus DNA sequence analyses combining three loci (ITS, TEF1 and RPB2) commonly used in previous phylogenetic studies of C. cassiicola (Shimomoto et al, 2011;Voglmayr & Jaklitsch, 2017).…”

First report ofCorynespora cassiicolacausing severe leaf blight onEucalyptusin Brazil

“…This species has a broad worldwide distribution in warm climates and has been reported from over 300 hosts, including tree species of the genus Tabebuia (Ferreira & Alfenas, 1980). The species includes populations with a high degree of host specificity, which have been recognised at the level of forma specialis (Pereira et al, 2003). A representative specimen was deposited in the local herbarium at the Plant Disease Clinic of the Universidade Federal de Viçosa (VIC39663).…”

Feeding and mating behavior of Dorcacerus barbatus (Olivier, 1790) (Coleoptera: Cerambycidae) on Lantana camara L. (Verbenaceae)

“…However, effective control has not been achieved yet because the combined impact remains insufficient to reduce the weed to acceptable levels and the biocontrol of the weed is considered negligible (Anonymous, 1999). Most of the established biocontrol agents are leaf feeders, which directed the search towards new candidate agents that feed on different parts of the plant (Winder & Harley 1983, Cilliers & Neser, 1991Palmer & Pullen, 1995;Broughton, 1999;Broughton, 2000, Palmer et al, 2000Thomas & Ellison, 2000;Baars et al, 2003;Williams & Madire, 2007) or pathogens (Thomas & Ellison, 2000;Pereira et al, 2003).…”
