Vector density monitoring method bug
1 Scope
This standard specifies methods for monitoring the density of bed bugs, including visual inspection and stick trapping.
This standard applies to indoor bed bug density monitoring, and the bed bug density monitoring in vehicles (sleepers) can be implemented by reference.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Bed bug
Bed bugs are insects of the genus Cimidae of the Insecta Hemiptera. They are incompletely metamorphic insects with three stages. egg, nymph and adult. To human property
The most harmful species are temperate bed bugs and tropical bed bugs.
2.2
Effective glue board
Sticky paper to bed bugs, or undamaged, unmoved and not sticking to bed bugs.
2.3
Signs of bed bug
The corpse, molting, eggs, feces of bed bugs, etc.
3 Monitoring method
3.1 Visual inspection
3.1.1 Appliances
Flashlight, magnifying glass, tweezers, dissecting needle, ziplock bag.
3.1.2 Operation method
In the monitoring room, select places where bed bugs inhabit, such as bed boards, mattresses (including holes, holes, and seams on them), bed frames, bed heads,
Drawers and other gaps and furniture joints, sofas, and furniture and pores around sofas and beds. Illuminate with a flashlight, use a magnifying glass, tweezers,
Dissecting needles and other tools, using direct visual inspection, tapping and other inspection methods to check and record the number of bed bugs caught in each place and the bed bugs found
trace. A single room with an inspection area less than 15 m2 is counted as one room, and a room larger than 15 m2 is counted as one room with 15 m2.Monitoring record table see
Table A.1 in Appendix A.
3.1.3 Presentation of results
3.1.3.1 Adult nymph density calculation
3.1.3.1.1 Infringement rate
Calculate the bed bug infestation rate according to formula (1).
3.1.3.1.2 Density
Calculate the bed bug density according to formula (2).
3.1.3.1.3 Density index
Calculate the bed bug density index according to formula (3).
3.1.3.2 Bed bug trace density calculation
Calculate the positive rate of bed bug traces according to formula (4).
3.2 Sticky trap method
3.2.1 Appliances
Sticky Worm (cockroach) paper. The glue surface specification is 170 mm×100 mm.
3.2.2 Operation steps
During the monitoring period, there should be people living normally in the monitoring room, and the bed bug stickers should be placed in places where bed bugs often inhabit and move, such as beds,
Around sofas, furniture, etc., the bed and sofa should be placed on the four corners that are in contact with the ground, and the number of sticky papers in each room
According to the specific choice of the furniture in the room. Leave the bed bug sticker for 7 days. Record the species and number of bed bugs caught, see Table A.2.for the monitoring record form.
3.2.3 Presentation of results
According to formula (5), formula (6), formula (7) and formula (8), respectively calculate the sticking catch rate, infringement rate, density and density index.
Appendix A
(Informative appendix)
Monitoring record sheet
Tables A.1 to A.2 give the record sheets suitable for bed bug density monitoring.
