Johnson-Cicalese, J., Baxendale, F.P., Riordan, T., & Heng-Moss, T. 1998 Identification of mealybug- (Homoptera: Pseudococidae) resistant turf-type buffalograss germplasm.. Journal of Economic Entomology 91: 340-346.
Notes: Two species of mealybugs, Tridiscus sporoboli (Cockerell) and Trionymus sp., have emerged as potentially serious pests of turf-type buffalograss, Buchloe dactyloides (Nuttall) Engelmann. Sixty-two buffalograss selections were screened for resistance to these mealybugs in 4 greenhouse trials. In field tests, mealybug infestations were highly variable, both within and among plots. However, in most cases, selections evaluated in the field showed similar responses as in greenhouse trials. Pubescence was positively correlated with buffalograss susceptibility to mealybugs. A glabrous leaf surface is suggested as a possible mechanism of resistance.
