[Biological characteristics of Asecodes hispinarum Boucek (Hymenoptera: Eulophidae), a parasitoid of Brontispa longissima(Gestro)(Coleoptera: Hispidae)]
Acta Entomologica Sinica 48 (6), 943-948
Abstract: Asecodes hispinarum Boucek, an important larval endoparasitoid of Brontispa longissima (Gestro), was introduced into Hainan Province of China from Vietnam in March, 2004. The morphology, development, reproduction and reproductive potential of this wasp parasitoid were studied. The results showed that under the laboratory condition of 24°C±2°C and RH 75%±10%, the mean developmental duration of egg, larva and pupa were 2.8 days, 6.7 days, and 7.5 days, respectively; the longevity of adults without nutritional supplement was 2.5 days on average. Both the temperature and nutritional supplement affected the longevity of adults, and the mean longevity of female adults was longer than that of male adults. Fecundity (per female) was 43 on average and the peak of oviposition occurred within 12 hours after mating. The functional response of A. hispinarum to 4th instar larvae of B. longissima belonged to Holling's type II, and the parasitization efficiency of A. hispinarum decreased with the increasing of A. hispinarum density.
