Objective: To investigate the Blomia tropicalis breeding status in the ground dust rice collected in Haikou City.
Methods: Totally 17 samples of ground dust rice were collected from 10 sampling sites in Haikou City. Then 10 g of dust rice was taken from each individual sample for isolation of the mites that were made of slide specimen, and the mites were identified and classified under a microscope.
Results: B. tropicalis mites were found in all the 17 samples with the detection rate of 100%. A total of 1 176 heads of B. tropicalis were isolated, with an average breeding density of 6.91 heads/g.
Conclusions: B. tropicalis breeding status is severe in Haikou City. The effective measures should be taken to prevent and control the harm associated with B. tropicalis contamination.
