Ten entomopathogenic fungi were tested for the control of female adult Thrips palmi Karny in the laboratory. The most virulent fungus Purpureocillium lilacinum CKPL-053, two commercial bioinsecticides and a chemical insecticide were tested for control of T. palmi in two Dendrobium sp. orchid farms.

The cowpea aphid (Aphis craccivora Koch) was chosen for further studies in its adult stage using B. bassiana CKB-048 as a(More)
