摘要

昆虫病原真菌（EPF）是专门感染并经常杀死昆虫和其他节肢动物的微生物。昆虫病原真菌是自然生态系统中最有效的昆虫生物控制剂，在生物密集型害虫管理中可以有效替代化学杀虫剂。Beauveria bassiana 是最普遍的土传昆虫病原体之一，对害虫具有毒力。本研究旨在评估从泰米尔纳德邦 Tirunelveli 地区棉田（Kuthukkal）土壤样本中分离出的本地昆虫病原真菌 B. bassiana 对 Dysdercuscingulatus 的致病性。用六种不同浓度的孢子（即 4.6 × 103、1.5× 104、5.0×105、2.7×106、3.2×107 和 2.8×108（孢子/毫升））对 D. cingulatus 的所有五个蛹态和成虫进行了生物效力试验。在处理后 120 小时，观察到高浓度 2.8 x 108（孢子/毫升）的死亡率为 100%。本研究的结果表明，该分离物似乎很有希望用于 D. cingulatus 的虫害防治。

PATHOGENICITY OF NATIVE BEAUVERIA BASSIANA (BALSAMO-CRIVELLI) VUILLEMIN ISOLATE ON DYSDERCUS CINGULATUS (HEMIPTERA: PYRRHOCORIDAE)

Entomopathogenic fungi (EPF) are the microorganisms thatspecifically infect and often kill insects and other arthropods. EPF is themost effective biocontrol agent against insects in the natural ecosystem whichcould be an effective alternative to chemical insecticides in bio-intensivepest management. Beauveria bassiana, one of the most prevalentsoil-borne entomopathogens, has virulence on insect pests. The present study isaimed to evaluate the pathogenicity of a native isolate of the entomopathogenicfungus B. bassiana isolated from the soil samples of a cotton field(Kuthukkal) in the Tirunelveli district of Tamil Nadu against Dysdercuscingulatus. Bio-efficacy trials were carried out with six differentconcentrations viz., 4.6 × 103,1.5× 104, 5.0 × 105, 2.7 × 106, 3.2 × 107,and 2.8 x 108 (spores/mL) in all the five nymphal instars and theadults of D. cingulatus. A 100% mortality was observed in higherconcentrations 2.8 x 108 (spores/mL) at 120hrs after treatment. The resultsof the present study show that the isolate seems to be highly promising in thepest management of D. cingulatus.
