摘 要：Objective: To test the effectiveness of conidial spore formulations [Aspergillus tubingensis(***) and Trichoderma harzianum(***)] against tropical bed bugs, Cimex ***: Spore formulations were made from two fungal strains, *** and *** bed bugs were exposed to the conidial spores placed soaked onto a fabric cloth for 1 h and the mortality counts were recorded daily until 14 ***: Mean survival times based on Kaplan–Meier survival analysis showed no significant differences between all the concentrations in both the fungal isolates:*** and ***, the evaluation of both the isolates in terms of virulence resulted in low lethal hours in all the concentrations except for the high concentration of ***(LT_(50)= 44.629 h) at the conidial exposure of 1 × 10~6 spores/*** mortality of the bed bugs was observed from Day 6 to Day 12, ranging from 13% to 90% in all three concentrations of *** reference to the *** exposure, the concentration of 1 × 10~4 spores/mL displayed a gradual increase in the percentage mortality of 90 on Day ***: Approaches to the bed bugs treatment should be explored in-depth using a natural biological agent like fungus especially *** to reduce this pest population, in order to replace chemical methods.
