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