Bioactivity of Soil-dwelling Entomopathogenic Fungi against Tessaratom apapillosa (Hemiptera:Pentatomidae)
摘要
Abstract
Iitchi stink-bug, Tessaratom apapilhsa Drury, often cause serious damage on litchi, Litchi chinensis and lon-gan, Euphoria longan, which are common varieties in orchard of South China. It is urgent to develop valid biological agent for control the pest and improve IPM strategy on orchard farming. Entomopathogenic fungi was regarded as a vital ecological factor pressing pest populations in field, however, there were few researches conducted on entomopathogenic fungi against litchi stink-bug. In this study, strains or isolates of Beauveria bassiana, Metarhizium anisopliae, Isaria fumosorosea and Isaria javanicus were isolated from soil samples of litchi orchards in South China. Virulence of forty strains was assayed for their efficacies against T. Apapillosa. Two strains, Bb07 and Ma03 demonstrated high toxicity, LC50 values at 14 d were 2.20× 106 conidia·mL-1 and 2.34× 106 conidia·mL-1, respectively, and LT50 values at 1 × 10 conidia · mL-1 were 6.1 d and 6.6 d, respectively. Furthermore, when Bb07 and Ma03 were sprayed at a concentration of 1 × 108 conidia'mL-1 in field trials, they achieved efficiencies of 90.78% and 90.34%, respectively.关键词
