一株寄生曲霉SF-2对甘蔗绵蚜的感染作用及其生物学特性初步研究
The Infection of a SF-2 strain of Aspergillus sp.on Sugarcane Aphid and Preliminary Study on Its Biological Characteristics
摘要
Abstract
[Purpose] Our aim was to provide the oretical basis for control of sugarcane aphid by using Aspergillus sp.SF-2.[Methods] The infection ratio of Aspergillus sp.SF-2 to Ceratovacuna lanigera (Zehntner) was tested by spore suspension spray method and its biological characteristics were preliminary studied by mycelium growth rate method and spore germination method.[Results] Aspergillus sp.SF-2 had infection effects on six kinds of homopteran pests,the infection effects were better on C.lanigera,Icerya purchasi Maskell and Unaspis yanonensis (Kuwana),the adjusted infection rate were 98.33％,98.25％ and 96.67％ spraying spore suspension 7 days after,respectively.At 32 ℃,pH 4.0 and light dark alternation,the mycelial growth of Aspergillus sp.SF-2 was the fastest.The best temperature of germination was about 32 ℃,and UV irradiation could significantly affect the germination of spores.[Conclusion] Aspergillus sp.has great potential in control of crop pests.关键词
