Abstract
In this study, entomopathogenic fungi were isolated from dead Lychee stink bug (Tessaratoma papillosa) in Taichung and Nantou of Taiwan. White mats with pinkish purple conidia emerged from the intersegmental membranes of antennae, legs and body, and the spiracles of dead bugs. The fungi were identified as Purpureocillium takamizusanense (Kobayasi) S. Ban, Azuma ＆ Hirok. Sato based on morphology and molecular characters, sequencing intergenic transcribed spacer (ITS) rDNA, transcribed elongation factor 1α (EF-α), and β-tubulin genes. Moreover, pathogenicity test showed that it killed adult bugs 14 days post-inoculation and had 85.2% mortality rate after 28 days of inoculation. Therefore, it shows high potential on biological control of Lychee stink bug in Taiwan.
