| Sumario: | <p>Control of <em>Plutella xylostella</em> L. can be done both biologically and chemically. Biological control is generally done by utilizing plant extracts to kill insect pests. This study aims to determine the effect of the extract of seeds on the mortality and development of parasitoid <em>Diadegma semiclausum </em>Hellen<em> </em>and its host, <em>P. xylostella</em>. The effect of Srikaya seed extract on <em>P. xylostella</em> larvae in the initial stage was tested by foliar rest method, while the residue method on the glass surface was used to test the effect of the extract of seed extract of Srikaya on the death of imago <em>D. semiclausum</em>. The effect of seed extract on parasitization and development of <em>D. semiclausum</em> was performed by exposing <em>P. xylostella</em> larvae contaminated by the extract of srikaya seeds in sublethal concentration (LC<sub>5</sub> and LC<sub>10</sub>) in imago <em>D. semiclausum</em>. The results showed that extract of srikaya seeds at a concentration of 0.0632<em>–</em>0.1% at 24-hour contamination affected the death of the larva <em>P. xylostella</em> and the imago parasitoids <em>D. semiclausum</em>. Imago parasitoids are more susceptible to increased concentration of extracts than <em>P. xylostella</em> larvae. The developmental resistance of <em>P. xylostella</em> by Srikaya seed extract at concentrations used is generally unreal. Similarly, the barriers to the development of parasitoid <em>D. semiclausum</em> in hosts contaminated with sublethal concentrations (LC<sub>5</sub> and LC<sub>10</sub>) of seed extract are generally not significantly different. The presence of Srikaya seed extract in the host also has no significant effect on the extent of parasitization, cocoon length, cocoon width, and cocoon weight. Therefore, there is a possibility to chemically and biologically integrate <em>P. xylostella </em>control.</p> |
