| Sumario: | <span>The objective of this research is to <span>study the effectiveness of <em>T. remus</em> as biocontrol agent for <em>S. exigua</em>. The <span>study was conducted by releasing a set of <em>T. remus</em> females on potted onion <span>plants that have been attacked by <em>S. exigua</em>. Three different parasitism level <span>was artificially created by releasing different numbers of females: low rate <span>parasitism (release of 4 adult females), moderate parasitism (7 females) and <span>high parasitism level (11 females). The result of this study showed that <em>T. </em><span><em>remus</em> is effective to control <em>S. exigua</em> population. Up to 48.2% of <em>S. exigua</em>. <span>population was able to be suppressed by the high parasitism level. Rate of <span>parasitisation was more when more adult female <em>T. remus</em> was released. <span>Release of 11 adult female of <em>T. remus</em> can increase the population level of <span>the parasitoid up to 24.1 times than the initial population. This express that <span><em>T. remus</em> is a mortality factor which can regulate the population of <em>S. exigua</em>. <span>However, the succesfull parasitisation of<em> T. remus</em> is also dependent on <span>environmental factors such as temperature, humidity, food, and host <span>suitability.</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span><br /></span> |
