[Morphological observation on hypopus of Lepidoglyphus destructor by optical microscope].

Objective To observe the external morphology of Lepidoglyphus destructor hypopus under an optical microscope. Methods The samples were collected in a store of Chinese medicinal herbs in Huainan City in September, 2016, the L. destructor and the hypopus were isolated, and then made of slide specimens. The slide samples were prepared and observed under an optical microscope. Results The L. destructor hypopus and protonymph were found. The inactive hypopus was oval in shape, the feet were not welldeveloped, there was a distinct transverse seam on its back, and there were 2 pairs of genital sensory organs. Conclusion The optical microscopy shows the morphological characteristics of L. destructor hypopus, which can provide the basis for the biological classification and the prevention.

[Hypopus of Acarus siro found in stored wheat].

OBJECTIVE: To observe the morphological characteristics of hypopus of Acarus siro in the stored wheat in Linquan County, Anhui Province. METHODS: The wheat samples were collected from the wheat which had been stored for more than six months. The hypopodes of A. siro were isolated from the stored wheat, and were made into the glass specimens, and then were identified under an optical microscope. RESULTS: The structural features of the hypopus were found under the microscope, such as the setae of tibia and setae of genu, and the foot claws were well-developed, and the genital seta bases and the pair of sucker were almost at the same baseline. CONCLUSIONS: The hypopodes of A. siro are found in the stored wheat, and therefore, the effective measures should be taken to control the hazard to the stored grain.

[Acarus farris hypopus found in stored wheat].

OBJECTIVE: To observe the morphological characteristics of Acarus farris hypopus. METHODS: The breeding mites from stored wheat samples were separated by a shake sieve and direct microscope. The isolations were used for slide preparation, and then the slide was observed under a light microscope for mite identification. RESULTS: The A. farris hypopus was found in the collected wheat samples. Under the microscope the boundary between the propodosoma and hysterosoma of the hypopus was obvious. The bristles on the hysterosoma were short, and the abdomen had a sucker plate. CONCLUSIONS: There is A. farris hypopus breeding in the storage wheat, and its morphological characteristics is similar with the characteristics of A. siro hypopus.

[Investigation and morphological observation of Histiostoma feroniarum breeding in Chinese herbal medicine Rhizoma Zingiberis].

OBJECTIVE: To understand the breeding situation of Histiostoma feroniarum in Chinese herbal medicine Rhizoma Zingiberis. METHODS: The Rhizoma Zingiberis sold on the market was selected and brushed. The dust from Rhizoma Zingiberis was screened under a microscope to search the mites. The mites were made into specimens to identify the species. RESULTS: The mites were H. feroniarum. Totally 14 mites were found in 100 g dust sample, with the density of breeding of 0.14/g. CONCLUSIONS: H. feroniarum could breed in Chinese herbal medicine Rhizoma Zingiberis, and the prevention and control measures should be adopted.

[Tyrophagus palmarum and its hypopus found in feed of Tenebrio molitor].

OBJECTIVE: To observe the Tyrophagus palmarum and its hypopus in feed of Tenebrio molitor. METHODS: Feed samples were collected from T. molitor farms, and T. palmarum and its hypopus were separated from the samples by the vibration sieve method and floating method. The glass specimens were prepared and T. palmarum and its hypopus were observed under an optical microscope. RESULTS: Under the light microscope, the skin of T. palmarum was smooth and bright, the color of legs and chelicerae was relatively dark, the length of dorsal seta d2 was 3-4 times longer than d1 and la; The ω1 in tarsus of leg Ⅰ, Ⅱ was short rod, and its top was not tapered; the sucker plate in tarsus of leg Ⅳ located in the middle of the section. The hypopus was oblate, and there were two pairs of legs in front which extended to body. The rear end of hypopus became pointless and round, wrapping around a transparent and ossification skin. CONCLUSIONS: Light microscopy shows the morphological characteristics of T. palmarum and its dormant body, providing the basis for identifying the hypopus.

Morphological observation on hypopus of Caloglyphus berlesei by optical mi-croscope / 中国血吸虫病防治杂志

Objective To understand the structure characteristics of hypopus of Caloglyphus berlesei. Methods The hy?popus of C. berlesei was collected from the feed of Chinese Polyphaga,and was made into the conventional glass specimens. The structure characteristics of hypopus of C. berlesei were observed by an optical microscope.
