| Sumario: | <p>The surveys of larval parasitiod <em>Plutella xylostella</em>, which have been done in cabbage plantations area in Batu and Poncokusumo, Malang east Java, found other larval parasitoid biside the commonly larval parasitiod <em>Diagdema semiclausum</em>. The parasitoid was <em>Teratichus howardi</em> (Hyminoptera: Eulophidae). The percentage of parasitism was dependent of the altitude of cabbage plantation and developmental stage of crop. The percent of parasitism could reach 82% when parasitized larvae sampled in cabbage plant and the crop stage. Parasitism was also higher at the medium lowland rather than it was that the upland. <em>T. howardi</em> is a gregrarious larval-pupa endoparasitoid. The life cycle of <em>T. howardi</em> was 14-16 days. The longevity of male and female was influenced by the availability of hosts or the change of mating. The longevity of mated female which was offered some host is 14-21 days, but the longevity of mated female without hosts was 38-56 days. The mated male parasitoid lived from 1 to 4 days, but they lived 12-16 days when they were not mated. One female could lay some cluster of egg varied from 35-60 eggs cluster or from 142 to 235 eggs during the lifespan. One eggs cluster consist of ±4 eggs. The parasitoid laid one or two clusters of egg per host. Parasitoid laid eggs soon after mating at day one from eclosion until day 19<sup>th</sup>. Four to 28 Parasitoids could emerge from one host. One parasitoid was able to parasitize 17-30 larvae of <em>P. xylostella</em>.</p> |
