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.
Insights
Acarus farris hypopus mites were found breeding in stored wheat. Their distinct morphological features, including a clear propodosoma-hysterosoma boundary and short bristles, were observed.
Area of Science:
- Agricultural Entomology
- Stored Product Pests
Background:
- Stored grains are susceptible to pest infestations.
- Mites can contaminate stored wheat, impacting quality.
Purpose of the Study:
- To document the morphological characteristics of Acarus farris hypopus.
- To confirm the presence of Acarus farris breeding in stored wheat.
Main Methods:
- Wheat samples were sieved to isolate mites.
- Microscopic examination was performed for identification and morphological analysis.
Main Results:
- Acarus farris hypopus was identified in stored wheat samples.
- Distinct morphological features were observed: a clear boundary between propodosoma and hysterosoma, short hysterosomal bristles, and an abdominal sucker plate.
Conclusions:
- Acarus farris hypopus actively breeds in stored wheat.
- The observed morphological characteristics are comparable to those of Acarus siro hypopus.
