“…To identify an appropriate Beauveria bassiana strain that causes mycosis of the sugarcane aphid for grain application in the field, two strains of B . bassiana , ABNB6 and Kudzu (Niland et al., 2019), were evaluated using a petri dish bioassay. Strain ABNB6 has been isolated from the coffee borer ( Hypothenemus hampei ) in Mexico (GenBank: KX196303.1) and soil samples from kudzu ( Pueraria montana var.…”

The sugarcane aphid [Melanaphis sacchari (Zehntner)] has become a persistent problem to sorghum [Sorghum bicolor (L.) Moench] producers in the United States since its first identification on grain sorghum near Beaumont, TX, in 2013. Since then, this aphid “super‐clone” has spread to almost all sorghum‐growing areas of the country. Growers have managed the sugarcane aphid using Insecticide Resistance Action Committee (IRAC) Group 4 insecticides and the use of resistant hybrids. In order to provide additional methods of control especially for organic sorghum production, two strains of the fungal entomopathogens Beauveria bassiana and one strain of Isaria fumosorosea as well as water and Sivanto (flupyradifurone) were applied to the sugarcane aphid susceptible sorghum hybrid DKS53‐53 in a randomized complete block design (RCBD) with four replications at Tifton and Fort Valley, GA. Aphid number, plant damage, grain yield, plant dry biomass, and plant height were measured for each treatment. As compared to the treatment with water, only the plots treated with Sivanto had significantly less aphid number and plant damage and significantly more grain yield and increased plant height. Thus, the applied entomopathogens did not reduce sugarcane aphid number, did not reduce plant damage, and did not increase grain yield in either location as compared to the treatment with water (the negative control). Thus, these three strains of entomopathogens were ineffective for controlling the sugarcane aphid under these field conditions.

Susceptibility of Different Life Stages of Kudzu Bug Megacopta cribraria (F.) (Hemiptera: Plataspidae) to Two Different Native Strains of Beauveria bassiana

This is the first study that examined and compared the survival, LC50, and RR50 estimates of Megacopta cribraria F. (Hemiptera: Plataspidae) nymphs and adults that were exposed to two native Beauveria bassiana isolates (Previously codified as NI8 and KUDSC strains) at four concentrations. The greatest reduction in survival and mortality was observed primarily on or after 10 d post-exposure to B. bassiana isolates. Survival of early instars (2nd, 3rd) were not affected by either strains or concentration at 3 d and 5 d post-exposure. Survival of later instars (5th) and adults was significantly reduced when exposed to the KUDSC strain at all concentrations. Comparison of dose–mortality values (LC50) using resistance ratios (RR50) were significantly different between life stages of the kudzu bug for both strains of B. bassiana. The LC50 values showed that kudzu bug adults are more susceptible than any other life stage when exposed to either strain. The KUDSC strain was more pathogenic than NI8 10 d after exposure, but NI8 exhibited significantly higher pathogenicity than KUDSC 20 d after exposure. Our results suggest potential field application of B. bassiana for kudzu bug control and their integration into pest management strategies to suppress them before they cause economic damage to soybean crops.
