Quarantine Identification Method for Khapra Beetle (Trogoderma granarium Everts)
1 Scope
This document describes the quarantine identification method for Trogoderma granarium Everts.
This document is applicable for the quarantine identification of Trogoderma granarium.
2 Normative References
There are no normative references in this document.
3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
hastisetae
Setae with arrowhead-like tips, possessing numerous small nodular structures along the shaft.
NOTE: Mainly distributed laterally on the dorsal plates of the larval abdomen, often clustered on the last four to five abdominal segments.
3.2
ensiform setae
Setae with finely pointed tips, overall sword-shaped.
NOTE: Ensiform setae are mostly distributed on the surface of the adult elytra.
3.3
spicisetae
Setae bearing many fine branches on the main shaft.
NOTE: Resembling awns or rat tails, distributed over most parts of the larval body, occasionally appearing on larval antennae.
3.4
epipharynx
The membranous lining attached to the inner surface of the labrum.
3.5
antecostal suture
A fine transverse groove on the anterior part of each thoracic tergite or most abdominal tergites of the larva.
NOTE: The external groove corresponding to the anterior internal ridge (antecosta) of the body segment.
3.6
antennal fossa
The groove or cavity where the antenna is located or hidden.
NOTE: In Dermestidae, located ventrally on each side of the pronotum, used to accommodate the antennal club of the adult.
3.7
subbasal band
A band structure formed by light-colored setae located on light-colored spots on the base of the anterior margin of the elytra.
NOTE: Also known as the "subbasal ring".
3.8
submedian band
A band structure formed by light-colored setae located on light-colored spots on the middle of the elytra.
3.9
subapical band
A band structure formed by light-colored setae located on light-colored spots on the apical part of the elytra.
4 Basic Information
Chinese name: Gu Ban Pi Lu
Scientific name: Trogoderma granarium Everts, 1898.
Synonyms: Trogoderma albonotatum Reiche in Mulsant & Rey, 1868; Trogoderma quinquefasciata Leesberg, 1906; Trogoderma khapra Arrow, 1917; Trogoderma koningsbergeri Pic, 1933; Trogoderma afrum Priesner, 1951; Trogoderma granarium ssp. Afrum Attia & Kamel, 1965.
English name: khapra beetle.
Taxonomic position: Order Coleoptera, Family Dermestidae, Genus Trogoderma Dejean.
The genus Trogoderma is one of the largest genera in the family Dermestidae and is also the most prominent genus in terms of economic significance and quarantine importance. Among them, eight species are of major economic importance: T. granarium, T. variabile, T. glabrum, T. inclusum, T. versicolor, T. sternale, T. anthrenoides, and T. teukton.
Other information on Trogoderma granarium is given in Annex A.
5 Principle of the Method
Based on the characteristics, distribution, host range, and damage caused by Trogoderma granarium, on-site quarantine is conducted to collect characteristic samples (larvae, cast skins, pupae, adults). Adult specimens are examined using a stereomicroscope for morphological characteristics and internal anatomical features. The morphological characteristics of larvae or cast skins need to be made into slide mounts and examined using a biological microscope. Larvae or pupae that are difficult to identify need to be reared to adults for observation. Identification is primarily based on the morphological characteristics of adults and certain larvae, biological characteristics, distribution, and pathways of transmission.
6 Apparatus and Reagents
6.1 Instruments and Equipment
Biological microscope, stereomicroscope, light incubator, oven, water bath (or metal bath).
6.2 Apparatus
Magnifying glass, scissors, forceps, insect dissecting needles, petri dishes, test tubes, rearing containers, sieves, glass slides, cover slips, alcohol lamp, beakers, perforated round sieves, wide-mouth bottles, specimen boxes, writing brushes, labels, etc.
6.3 Reagents
Hoyer's mounting medium [50 mL water (H₂O), 30 g gum arabic (C₂₂H₃₀O₂₉), 200 g chloral hydrate (C₂H₃Cl₃O), 20 mL glycerol (C₃H₈O₃)]; 10% sodium hydroxide (NaOH) or 10% potassium hydroxide (KOH) solution; 75% ethanol solution (C₂H₅OH).
Unless otherwise specified, all reagents are of analytical grade.
