Embodiment 1

[0041] Embodiment 1, the rapid identification in the field of rumworm larvae in Kalamaili Nature Reserve, Xinjiang

[0042] The present invention summarizes the morphological characteristics of more than 70,000 botfly third-instar larvae identified in the work in the past ten years, and designs a method for quickly identifying botly larvae in the field without a microscope. This method has universal It can be a convenient and practical method to carry out relevant research.

[0043] 1. In February 2014, the reintroduced Przewalski's wild horses in the Kalamaili Nature Reserve in Xinjiang were dewormed and 13,702 third-instar larvae were collected. Through the morphological observation of the number of spines, body color, head characteristics and spine morphology, 13702 collected third-instar larvae of rum flies were quickly classified and identified according to the following key table, and were classified and preserved.

Embodiment 2

[0062] Example 2. Population Dynamics of Przewalski's Wild Horses Infected with Rutonia larvae in Kalamaili Nature Reserve, Xinjiang

[0063] 1. From April to June 2014, a follow-up survey was carried out on the wild horses released in the Kalamaili Reserve in Xinjiang. A total of 328 third-instar larvae of the rum flies were collected and quickly identified in the field according to the following methods:

Abstract

The invention discloses a method for authenticating various third instar larvas of horse bot flies. The method can authenticate Gasterophiluspecorum, G.intestinalis, G.inermis, G.nigricornis, G.haemorrhoidalis and G.nasalis according to characters such as arrangements of calthrops of somites, body colors, arrangements of calthrops between mouth hooks at heads and mouth hooks at backs, shapes of calthrop tails on body surfaces, and arrangements of calthrops at the second somites. The method aims at defects in the prior art, and can quickly authenticate third instar larvas of six kinds of horse bot flies recorded in our country in the wild on the basis of morphological observation, detailed classification and results of comparison. The method can be used for accurately and timely classifying and authenticating third instar larvas of horse bot flies collected in the wild.

Description

technical field [0001] The invention relates to a method for identifying rum flies, in particular to a method for identifying third-instar larvae of rum flies, belonging to the field of insect species identification. Background technique [0002] The genus Diptera (Diptera), Cyclorrhapha (Gasterophilidae), originated in the Palaearctic and Ethiopian regions, and now it has spread all over the world, and 6 species have been found in my country, which are black-bellied stomach Gasterophilus specorum, G. intestinalis, G. inermis, G. nigricornis, G. haemorrhoidalis and G. nasalis ). [0003] The rum fly develops through four stages: egg, larva, pupa and adult, and completes a life cycle every year. Among them, the larvae are divided into three stages. The first-instar larvae parasitize in the submucosal or tongue surface tissue for 3-4 weeks, and then metamorphose into the second-instar larvae. third instar larvae. The third instar larvae, as an important stage in the developm...
