Introduction

Ceratopogonidae is a tiny insect in the Diptera insect, which is more than 50 species of human and livestock diseases.

Pathogen transmission vector. The spread of blood-sucking mites carrying pathogens has long been reported. However, there is no ship that has entered the international voyage Reports with cockroaches. From.2002 to 2003, Qinhuangdao Entry-Exit Inspection and Quarantine Bureau conducted a special investigation on the inbound international navigation vessels and found that the positive rate of mites was 68.71%, and a total of 1256 imported mites were obtained, belonging to 9 genera; among them, the blood-sucking mites identified were 3 genera and 9 species.

Among them are Culicoidesfurens (Poey), CulicoidesmarksiLeeetReye, and the genus Lasio-HeleatenuidentisYuetWirth and abundant species such as LeptoconopsgrandisCarter and new species of Poseidon LasioheleacymodoceaYu, LietNie, 2003. This is the first time that China has discovered imported mites on ships entering international voyages.

Report.

Sea god 蠛蠓LasioheleacymodoceaYu, LietNie, 2003 is by Qinhuangdao Entry-Exit Inspection and Quarantine Bureau Nie Weizhong on April 26, 2003, the Panamanian "Tanfu" round (MV) arrived at the quarantine anchorage of Qinhuangdao Port from Davao Port (DAVAO) in the Philippines.

"TENFU") was collected from 5 adult mites, identified as a new species, named as the sea god 蠛蠓LasioheleacymodoceaYu, Li, etNiesp.nov 2003. The above specimens are modeled, with (male), 副3(female)(female), collected in the Medical Insect Museum (Beijing, Fengtai East Street) no. 20, 100071). This is an important new species and major achievement discovered by quarantine personnel in the field of imported medical media biological monitoring.

one.

In view of the new species named after the first discovery of the sea god, and there is no relevant standard data for reference, the relevant personnel cannot accurately Grasp the morphological characteristics and identification points. In order to improve the health, quarantine personnel at the border ports, carry out the monitoring, identification, prevention and control of imported mites Level, it is necessary to formulate this standard, scientific description and introduction of the morphological characteristics and identification points of male and female adults of P. striata, with Relevant identification points image, to provide you with a scientific, practical and operative quarantine identification methods and procedures to ensure Correct identification and identification of sea gods.
