The two-spotted spider mite, Tetranychus urticae, is an important mite pest worldwide. It often leads to reduced crop yields or poor marketability of the produce and has already developed resistance to many acaricides. In this study, the pathogenicity of the entomopathogenic fungus (EPF), Acremonium hansfordii, to T. urticae and its side effects on the predatory mite Neoseiulus barkeri were compared. The toxicity of A. hansfordii was evaluated on T. urticae at 1.0×104, 1.0×106, 1.0×108 conidia/mL concentrations and predatory mite N. barkeri at 1.0×108 conidia/mL under experimental conditions at 25±1°C, 75±5% RH and 16L: 8D photoperiod. The effects of EPF on the development of the F0 and F1 generation of predatory mites were also assessed at 1.0×108 conidia/mL concentration. The results showed that the corrected mortality of T. urticae at three tested concentrations were 36.67%, 53.67% and 66.33% within 11d, and the median lethal time were 14.39 d, 9.84d and 7.99d, respectively. The corrected mortality of N. barkeri was only 3.9% after 11d at 1×108 conidia/mL concentration. Some hyphae of A. hansfordii were detected on the surface of treated T. urticae but not on N. barkeri body after 7d. After N. barkeri females were treated with 1.0×108 conidia/mL, the preoviposition period of the F0 generation was prolonged 1.56 times and the other life history parameters have no significant differences; similar patterns were also shown in the F1 generation. A. hansfordii showed strong pathogenicity against T. urticae but did not significantly adversely influence N. barkeri. Therefore, the combination of A. hansfordii and N. barkeri has the potential to be used for the control of T. urticae in the future.

Prey Stage Preference

Raoiella indica Hirst (Acari: Tenuipalpidae) is a polyphagous pest widely dispersed worldwide and a particular threat to crops from the Arecaceae family. Control measures are still being evaluated in recently invaded countries. A possible control strategy for this pest is the use of predatory mites. A recent study has suggested Neoseiulus barkeri Hughes (Acari: Phytoseiidae) as a potential biological control agent of R. indica. In the present study we determined the prey stage preference of N. barkeri when offered different stages of R. indica besides its functional response and numerical over its prey stage preferred. The predatory mite N. barkeri showed a marked preference for eggs over other stages of the prey. The regression analysis indicated that the predatory mite N. barkeri exhibited a Type II functional response. The prey density needed to start the oviposition was 10 R. indica eggs. The number of eggs laid by N. barkeri females increased with an increase in the prey density and tended to stabilize when prey availability was greater than 80 R. indica eggs, with average oviposition of 2 eggs/female. Our study suggests that N. barkeri shows potential to reduce populations of R. indica, especially at low prey densities. However, further studies are needed to investigate whether R. indica supports the development of immature stages of N. barkeri.

Niemann Pick

In arthropods, a host of studies focused on insect olfactory systems, where most functional proteins including odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) have been identified. However, in other arthropods such as ticks and mites, genes encoding for OBPs and CSPs are absent. The Niemann-Pick type C2 (NPC2), as a third class of binding proteins, was indicated as potential carriers for semiochemicals and participants in chemical communication. Here, we cloned three full-length NPC2 genes (NbNPC2-1, NbNPC2-2 and NbNPC2-3) from a predatory mite Neoseiulus barkeri Hughes (Acari: Phytoseiidae) and investigated the expression levels of these genes by quantitative real-time PCR. These NPC2 proteins possessed a conserved motif of six cysteines paired in three disulfide bridges with a coincidence to insect OBPs. The 3D molecular modeling of NbNPC2 showed ligand-binding pocket of NbNPC2-1 was composed of a flexible β-structure that contributed to binding to a wide range of potential semiochemicals. Three NPC2 genes all possessed one signal peptide revealed their specific character as secretory proteins. Three NPC2 genes in N. barkeri displayed the highest expression levels in adult males, suggesting a putative role in detecting of the female sex pheromones and highly specific binding to female sex pheromone. The expression levels were lowest in the stage of eggs and increased with developmental stage growing, indicating that NPC2 genes were continuously expressed in post-embryonic stages. NbNPC2-1 in the stage of adult females was expressed 6 and 4 times higher than that of larva and nymph, suggesting NbNPC2-1 might contribute an important role in odor recognition of adult females to hunt for suitable areas for the oviposition and predation. These results showed that NPC2 genes might be involved in chemical communications of adult males, and that NbNPC2-1 preformed specified olfactory functions in adult females. This study provided a foundation for research to determine the roles of NPC2 proteins acting as odorant carrier and involved in chemical communication in phytoseiid mites.
