Abstract

Sphenophorus venatus vestitus responses to 4 bermudagrass cultivars and endophytic perennial ryegrass-overseeded bermudagrass were evaluated in greenhouse tests. ‘TifEagle’ appeared to be least preferred, compared to ‘Tifway’, ‘Celebration’ and ‘Tifdwarf ’. Pots of ‘TifEagle’ overseeded with endophytic perennial ryegrass had less adult damage and no larvae, compared to that of ‘Tifway.’ Using less susceptible cultivars and overseeding with endophytic turfgrasses can minimize billbug populations in warm season turfgrasses.

 

Se evaluó la respuesta de Sphenophorus venatus vestitus a 4 variedades de césped Bermuda con centeno (raigrás) endofítico perenne sembrado por encima en un ensayo de invernadero. La variedad ‘TifEagle ‘parece ser menos preferida, en comparación con las variedades ‘Tifway’, ‘Celebration’ y ‘Tifdwarf’. Las macetas de ‘TifEagle’ sembradas con centeno endofítico perenne por encima tuvieron menos daño hecho por los adultos y no tenían larvas, en comparación con las de ‘Tifway. Al utilizar variedades menos susceptibles y sembrar los céspedes endófitos por encima puede minimizar las poblaciones del picudo en céspedes de estación cálida.
