“…Young and old kudzu bug adults treated with the commercial strain GHA showed low mortality and sporulation at all concentrations ( Figure 1 , Figure 2 and Figure 5 ). Similar results have been observed in several studies using commercial isolates of B. bassiana where moderately effective control of targeted insects was reported [ 18 , 21 , 31 , 32 , 33 , 34 ]. The present results support previous observations that pathogenicity of B. bassiana is not always related to the original host or geographical origin [ 33 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ].…”

The kudzu bug, Megacopta cribraria (F.), is an urban nuisance and significant agricultural pest. The median lethal concentrations of three strains of Beauveria bassiana (Balsamo), including the Mississippi Delta native strain (NI8) isolated from Lygus lineolaris (Palisot de Beauvois), the commercial strain BotaniGard® (GHA) (Victor, NY, USA), and the B. bassiana strain isolated from M. cribraria (KUDSC), were estimated on kudzu bug adults. A technique developed to evaluate B. bassiana against L. lineolaris was used. Younger adults (eight days after collection) were treated with NI8 and GHA and older adult (50 days after collection) were treated with NI8, GHA and KUDSC. Higher concentrations (n × 106, n × 107) of NI8 and GHA caused kudzu bug mortality two days after treatment in younger adults and similar concentrations of NI8, GHA, and KUDSC caused mortality one day after treatment in older adults. Lower concentrations (n × 104, n × 105) were not significantly different in mortality between strains. LS50 values of the KUDSC were significantly lower than NI8 and GHA values in older adults. This is the first available information on median lethal concentration of B. bassiana on kudzu bug adults bioassayed on artificial diet. It was determined that B. bassiana (KUDSC and NI8) are highly effective for young adults at very low doses (LC50 1.98–4.98 viable spores per mm2).

“…Reduced fecundity in Colorado potato beetle surviving treatment with B. bassiana was shown to be temperature dependent by Fargues et al (1991), whereas Wang and Knudsen (1993) found no difference in nymph production in surviving Russian wheat aphids. Noma and Strickler (2000) recently reported a reduction in the oviposition rate of lygus bugs treated with B. bassiana but only in insects that did not produce spores at the end of the experiment.…”

“…In the Noma and Strickler (1999) study, temperatures within the plant canopy were observed to be in excess of 30°C during the July trials; the upper thermal limit for this strain is 32-34°C. In subsequent laboratory experiments, Noma and Strickler (2000) demonstrated that infections were greatly reduced at 35°C, compared to 25°C. Temperatures below 16°C increasingly slow germination and growth rates for most of the fungal entomopathogens, and thus affect efficacy in terms of a longer survival of the target population (Inglis et al 1999;Ihara et al 2008).…”

Ecological factors in the inundative use of fungal entomopathogens

2009

View full text Add to dashboard Cite

Fungal entomopathogens have been developed in numerous countries as biocontrol agents with more than 100 mycoinsecticide products commercially available in 2006. The chief, perhaps sole, use of these mycoinsecticides has been as inundative agents, within a chemical paradigm. Large numbers of propagules are applied in an attempt to overwhelm by brute force many of the factors that keep a pathogen in nonepizootic equilibrium with its host. This review attempts to summarize what we know about the abiotic and biotic factors that affect the efficacy of these mycoinsecticides in both foliar and soil applications. Sunlight, humidity, temperature, and phylloplane-associated factors can affect both immediate efficacy and persistence on plants. Likewise, soil texture-moisture interactions, temperature, and a host of biotic factors can affect mycoinsecticides in the soil. Despite much research, our understanding of these ecological aspects is imperfect, especially in a holistic, dynamic sense.
