病原菌上澄み製剤の殺アリマキ活性に及ぼすイソトリデシルアルコールのエトキシル化の効果

抄録

When the insect-killing (entomopathogenic) fungal supernatant is considered for biological pest control, incorporation of an appropriate surfactant is required to allow the supernatant to work on insect cuticles. The Beauveria bassiana (SFB-205) supernatant with less ethoxylated isotridecyl alcohol (TDE) had higher insecticidal activity against adults of the cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae). Incorporation of TDE to the supernatant increased the potency of the fungal supernatant in an ethoxylation-dependent manner, representing a practical approach to effectively control cotton aphids.
