  "abstract": "<p>This study aimed to determine&nbsp;1) the effects of fungal filtrates containing secondary metabolites&nbsp;from five different isolates of four different&nbsp;<em>Trichoderma</em>&nbsp;species (<em>Trichoderma afroharzianum</em>,&nbsp;<em>T. guizhouense</em>,&nbsp;<em>T. harzianum</em>, and&nbsp;<em>T. virens</em>)&nbsp;grown in different liquid media&nbsp;[malt extract broth (MEB), potato dextrose broth (PDB), yeast peptone glucose (YPG), minimal medium (MM), czapek-dox broth (CDB)]&nbsp;on&nbsp;<em>Tetranychus urticae</em>&nbsp;female,&nbsp;and&nbsp;2) the effects of&nbsp;<em>Trichoderma</em>filtrates obtained from YPG liquid media&nbsp;on the different biological stages of&nbsp;<em>T. urticae</em>&nbsp;in Petri dish and pot experiments.&nbsp;Results showed that the&nbsp;<em>Trichoderma&nbsp;</em>filtrates&nbsp;produced in the YPG medium exhibited the highest mortality rate of 67.6 - 83.1 % against&nbsp;<em>T. urticae</em>&nbsp;females at 7 days post-application (dpa) compared to other media. In Petri dish experiments, the mortality rates of&nbsp;<em>Trichoderma</em>&nbsp;&nbsp;filtrates&nbsp;on egg, larva, protonymph and deutonymph stages of&nbsp;<em>T. urticae</em>&nbsp;at 7 dpa were 54.0 - 57.8 %, 71.5 - 76.0 %, 72.5 - 79.8 % and 72.8 - 80.8 %, respectively. Significant differences were observed between the&nbsp;<em>Trichoderma</em>&nbsp;species and control (P &lt; 0.01) but not among the&nbsp;<em>Trichoderma</em>&nbsp;species (P &gt; 0.05).&nbsp;<em>Trichoderma afroharzianum&nbsp;</em>(83 %) and&nbsp;<em>T. virens&nbsp;</em>(84 %) showed the highest mortality rate on&nbsp;<em>T. urticae</em>&nbsp;adult females at 7 dpa and statistically significant differences were observed among&nbsp;<em>Trichoderma</em>&nbsp;species.&nbsp;Pot experiments revealed that the number of viable&nbsp;<em>T. urticae</em>&nbsp;eggs and mobile stages was significantly lower for&nbsp;<em>T. afroharzianum</em>&nbsp;(110.3 eggs, 105.8 mobile stages) and&nbsp;<em>T. virens</em>&nbsp;(118.5 eggs, 115.3 mobile stages) compared to the control (518.9 eggs, 452.5 mobile stages) at 7 dpa.&nbsp;Significant differences were observed between&nbsp;<em>Trichoderma</em>&nbsp;species and control, but not between&nbsp;<em>T. afroharzianum</em>&nbsp;and&nbsp;<em>T. virens.&nbsp;</em>These findings suggest that&nbsp;<em>Trichoderma</em>&nbsp;secondary metabolites are highly effective against economically important pest such as&nbsp;<em>T. urticae</em>, demonstrating their potential as bio-acaricides.&nbsp;Future research should focus on identifying the specific acaricidal compound(s) within these filtrates.</p>",
