Redescription and new record of Odontoscirus nipponicus Shiba, 1985 (Bdellidae: Odontoscirinae) from China with a description of its ontogeny.

Odontoscirus nipponicus Shiba, 1985 is recorded from China and is redescribed; male, tritonymph, deutonymph, protonymph, and larva are described and illustrated for the first time. Morphological observations on the ontogeny of this species are also provided.

Redescription of Ewing, 1909 (Bdellidae: Bdellinae) from China with Its First Description of Ontogeny.

Ewing, 1909 was redescribed and illustrated in detail, and its ontogeny was described and illustrated for the first time, including pro dorsal apodeme and chaetotaxy. Chaetotaxy changes in are mainly focused on ventral hypostomal setae (), setae on palpal basifemur, aggenital setae (), genital setae (), anal setae () and leg setae. Furthermore, an original key to the species from China was also provided.

Juvenile Hormone Is an Important Factor in Regulating Dallas Diapause.

is a Chinese traditional edible and medicinal insect, which is in great demand in the society. This insect reproduces once a year which is caused by reproductive diapause resulting in insufficient production in wild resources. However, the mechanism of diapause in is still unclear.

First description of immature stages and redescription of female Bdella longicornis (Acari: Prostigmata: Bdellidae), with an ontogeny of chaetotaxy.

Bdella longicornis (Linnaeus, 1758) is a widespread species. There has been no description of its immature stages before. In this paper, we redescribe its female adult and describe its four immature stages for the first time based on the specimens from P.

[Long-range transport potential of typical organic pollutants in Nanjing].

In this study, the long-range transport potentials (LRTP) of typical organic pollutants including p,p'-DDT, gamma-HCH, BaP and HCB in air and water of Nanjing were estimated using the TaPL3 model. The research results showed that the characteristic travel distances (CTD) of BaP and p,p'-DDT through air were relatively low, 198 km and 255 km, respectively, indicating relatively low LRTP and difficulty in pollution dispersion. In contrast, gamma-HCH and HCB tended to transport over longer distances through water and air, with CTD values of 91 558 km and 19 056 km in water and 1 858 km and 21 104 km in air, respectively, indicating that the dispersion of pollution in air and water of the studied area was relatively easy.
