Descripción
Gyropsylla spegazziniana is an important pest of yerba mate Ilex paraguariensis, due to its feeding and reproductive habits. It substantially impacts the development of the plant by forming galls in the young leaves and affecting the production and quality of the leaves, resulting in economic loss to the growers. Since yerba mate is consumed in natura, non-chemical ways to control this insect are needed. Previous laboratory studies showed the potential of attract-and-kill devices covered with conidiospores of the entomopathogen Beauveria bassiana to control G. spegazziniana. In this study, we conducted laboratory and field tests to evaluate the potential of two designs of devices (rectangular and roof-shaped) to manage G. spegazziniana populations and their capacity to protect conidiospores from direct sunlight (specially UV-B). We also conducted laboratory tests to evaluate horizontal transmission from living infected individuals and mycosed cadavers to healthy adult insects. Field tests were conducted in February and March, when the insect populations were at their highest annual densities. Attraction and infection levels were similar for both types of dispensers in both the laboratory and field tests. However, conidiospore viability last longer in the roof-shaped dispensers, which shaded the spores from direct sunlight. We also observed in laboratory high levels of horizontal transmission from both infected alive individuals and mycosed cadavers, with mortality rates reaching 87% and 72%, respectively. The results demonstrate the potential of attract-and-kill devices covered with B. bassiana conidiospores to control G. spegazziniana in yerba mate plantations.
