摘要: Neoseiulus cucumeris (Oudemans) (Acari: Phytoseiidae) is one of the most widely used and important biological control agents for thrips other small pests worldwide. In present study, we cloned two cDNAs vitellogenins (Vgs, NcVg1 NcVg2) analyzed effect food source on expression both Vgs fecundity in female adults. NcVgs showed higher sequence similarity to from Parasitiformes. Both neighbor-joining maximum likelihood methods phylogenetic analysis yielded similar topologies that Parasitiformes except Haemaphysalis longicornis segregated into a single clade was separated subclades including N. cucumeris. transcripts, NcVg2 revealed trends during developmental periods reached level at pre-oviposition period. When fed with different sources, adults demonstrated significant difference (P < 0.05) Meanwhile, positive correlation between observed. Therefore, nutrients provided by sources affected resulting differential Vgs. Vitellogenin can be as molecular marker
