Abstract:

Objective To understand the infestation situation of major vectors in public places in Henan for the provision of a scientific basis on which the measures for the control and prevention of the vectors in public places in the area were developed. Methods Survey of the infestation situation of major vectors in the area was implemented in four types of public places including hotels, restaurants, schools and medical facilities. Both Powder-spot method and rodent trace method were used for the surveillance of rodent, with sticky-paste method for cockroach, eyeballing method for flies, labor hour method for adult mosquito and container index method for mosquito larvae and pupae. Results With the powder-spot method and rodent trace method, the positive rate of rodent were 5.23% and 4.02% respectively. The positive rate per room for cockroaches was 11.97%, with an average of 8.81 cockroaches per room in the positive rooms, being highest in the restaurants. The positive rate room for flies was 22.38% with an average of 2.43 flies per room in the positive rooms, being highest in the restaurants. The adult mosquito density was 6.49/(man·hour)with Culex pipiens pallens being the dominant species. The positive rate of mosquito larva and pupae was 19.06%. Conclusion It is seen that only the average number of flies in the positive room meets the standards and all the other major indexes were beyond the acceptable limits, indicating that the infestation situation of important vectors in public palaces in Henan was serious, and great importance should be attached to the control and prevention of vectors in public palaces in Henan.
