Abstract:
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 vibra?tion sieve method and floating method. The glass specimens were prepared and T. palmarum and its hypopus were observed un?der 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;Theω1 in tarsus of legⅠ,Ⅱwas short rod,and its top was not tapered;the sucker plate in tarsus of legⅣlocated 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. Conclusion Light microscopy shows the morphological charac?teristics of T. palmarum and its dormant body,providing the basis for identifying the hypopus.
