Performance of the two parasitoid species, Aphelinus varipes and Lysiphlebia japonica against sugarcane aphid, Melanaphis sacchari
Sugarcane aphid, Melanaphis sacchari Zehntner, is an important piercing-sucking pest on sorghum, sugarcane, and other graminaceous crops, not only damaging host plants by direct feeding, but also transmitting plant viruses that is detrimental to crop production. To evaluate the performance of two native parasitoid species, Aphelinus varipes (Förster) and Lysiphlebia japonica (Ashmead), on M. sacchari, the age stage, two-sex life table analysis was conducted to evaluate the demographic parameters of the two species. The results showed that the two parasitoids parasitized M. sacchari and completed their whole life history. The number of eggs laid by A. varipes (F: 209.49 offspring/female) and the number of oviposition days (Od: 14.18 d) were significantly higher than those of L. japonica (F: 87.47 offspring/female, Od: 3.36 d). Moreover, the intrinsic rate of increase (r), finite rate of increase (λ), and net reproductive rate (R0) of A. varipes (r: 0.3746 d-1, λ: 1.4160 d-1, R0: 113.125 offspring/individual) were significantly higher for A. varipes than those of L. japonica (r: 0.3386 d-1, λ: 1.4030 d-1, R0: 48.092 offspring/individual). In addition, the net killing rate (C0) of A. varipes was 119.57 (eggs/female), which was significantly higher than that of L. japonica (53.34 eggs/female). These findings suggested that A. varipes had higher performance with promising potential as biological control agent for sugarcane aphid.
期刊介绍：
Biological control is an environmentally sound and effective means of reducing or mitigating pests and pest effects through the use of natural enemies. The aim of Biological Control is to promote this science and technology through publication of original research articles and reviews of research and theory. The journal devotes a section to reports on biotechnologies dealing with the elucidation and use of genes or gene products for the enhancement of biological control agents.
The journal encompasses biological control of viral, microbial, nematode, insect, mite, weed, and vertebrate pests in agriculture, aquatic, forest, natural resource, stored product, and urban environments. Biological control of arthropod pests of human and domestic animals is also included. Ecological, molecular, and biotechnological approaches to the understanding of biological control are welcome.
