SN/T 1855-2017Detection and identification of Bruchidius atrolineatus(Pic) (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces SN/T 1855-2006 "Dark Bean Quarantine Identification Method", compared with SN/T 1855-2006, except for editorial repair in addition, the main technical changes are as follows.

--- Added basic information on dark beans (see Chapter 3);

--- Improve the principle of the method (see Chapter 4, Chapter 2 of the 2006 edition);

--- Increased the main morphological characteristics of the Beans and Beans (see 6.6.1 and 6.6.2);

--- Improved the morphological characteristics of the adult worms (see Appendix D, Appendix D of the 2006 edition);

--- Removed the preparation of reagents (see Appendix B of the 2006 edition);

--- Improved the search form (see Appendix C, Appendix C of the 2006 edition).

This standard is proposed and managed by the National Certification and Accreditation Administration.

1 Scope

This standard specifies the quarantine and identification methods for the dark-striped bean elephant Bruchidiusatrolineatus (Pic).

This standard applies to the quarantine and identification of dark bean images.

2 Terms and definitions

The following terms and definitions apply to this document.

Male basal lateral projection parameres it is a component of the male external genitalia. Located on the back of the Yangji, it consists of two leaves, which are spoon-shaped and have enlarged ends. In different groups, two Some of the basal protrusions are separated at the base, some are healed, and some are almost completely healed.

Male stalk, inner stalk and inner stalk pharyngeal phalus, endophalus anditssclerires the penis is a component of the male external genitalia. It is located on the ventral surface of the basal ganglia and is rod-shaped. The base is swollen and saclike (called the sac area), and the end is early.

Petal (called outer stalk). The stalk is divided into the outer stalk and the inner stalk. The outer stalk is the outer shell portion of the stalk. Inner stalk membranous, lined in the outer yang Inside the stem, when the males mate, they turn over the mountains through the end of the stem. A large number of ossified thorns are placed on the inner stalk, arranged in a certain pattern, with a species the specificity is one of the important basis for the identification of the insect species of the Beans.

3 Dark strips of beans like basic information

4 Principle of the method

According to the damage of the insects of the dark-striped insects, when the larvae or the mites are not determined, it is necessary to raise the adults and then in the stereo microscope.

Under the microscope, the species was judged according to the morphological characteristics of the adults. Morphological characteristics, distribution, transmission pathways and biological characteristics of adults Sex provides the basis for the development of this quarantine method.
