    Bemisia tabaci is a major pest of soybeans and a vector of plant viruses. This study aimed to evaluate and compare the efficacy of four entomopathogenic fungi for suppressing B. tabaci populations on soybeans. The four treatments were L. lecanii, A. aleyrodis, M. anisopliae, and B. bassiana, a comparison with the insecticide thiamethoxam and a control group without treatment. The four types tested were able to suppress B. tabaci populations by up to 75%, with A. aleyrodis being especially effective. There was no significant difference in efficacy between the four types and the insecticide thiamethoxam. Validating the efficacy of entomopathogenic fungi, there were no significant differences in plant height, dry stover weight, or number of pods between treatments with the insecticide thiamethoxam. However, significant differences occurred in the number of empty pods and seed weight, reducing yield losses by up to 78%. There was a positive correlation between the B. tabaci population and the number of empty pods (r = 0.80), while there was a negative correlation between the B. tabaci population and plant height and soybean yield (r =-0.56 and r =-0.54, respectively).

    Two new Ophiocordyceps species from Thailand, which belong to Ophiocordyceps nutans species complex and attack adult and nymph of stink bugs, are described: Ophiocordyceps asiana and O. tessaratomidarum. Molecular phylogenetic analyses of ITS and a combined sequence data of LSU, RPB1 and TEF1 revealed that these two new species are distinct from other known species in Ophiocordyceps nutans species complex. Based on the findings on morphological studies, they further support the naming of these two novel species. Ophiocordyceps asiana is parasitic on adult and nymph stink bugs, members of Coreidae and Pentatomidae which were recorded from China, Japan and Thailand, while O. tessaratomidarum is reported from Thailand for the first time and is only found as a parasite on adult stink bug, Tessaratoma papillosa (Tessaratomidae, Hemiptera). The fertile heads of O. asiana are shorter than reported for O. tessaratomidarum, and the colours of fertile heads producing teleomorph of these two species differs from each other by having strong reddish orange or light yellowish pink in O. asiana and pale yellow in O. tessaratomidarum.
