Abstract/Contents: | "Fall armyworm larvae (Spodoptera frugiperda) feed on most of the turfgrasses in Texas and cause damage to managed turf at least every third yr. Larval populations are routinely managed with pesticides, but alternative control strategies are being investigated. Laboratory studies were initiated to assay the efficacy of BioCide-TRF (Mycotrol GH-ES) Beauveria bassiana Vuill, an entomogenous fungus for management of FAW larvae. Terminal stolons of Common bermudagrass (Cynodon dactylon) were dipped in dilutions (1:100, 1:1,000, 1:10,000 and 1:100,000) of BioCide-TRF (2.0 x 10¹³ conidia/qt), and exposed to 5-d-old fall armyworm larvae in feeding chambers. Larvae treated with the highest dose (1:100 dilution) of Beauveria exhibited high mortality of 61.4% at 5 d, 90.3% by 8 d and 95.3% were dead within 15 d of exposure to the fungus. The only other inoculation to provide any control was the 1:1,000 dilution which provided 23.8% by 15 d, and 33.3% within 20 d of inoculation. Less than 5% mortality was present in the untreated check during the same 20-d test period." |
