Benefits of technology

The present invention relates to a trap for catching ecdysozoans, which are small arthropods that can cause damage to plants and trees. The trap has a floor, roof, vertical walls, and at least one interior surface coated with a sticky substance. The interior surface can be the interior surface of the roof or the inside of the walls. The trap has a sloping floor or roof, and may also have distinct slopes on both the floor and roof. The sticky substance can be tacky glue or double-sided adhesive tape, and may also contain attractive agents like sexual attractants or pheromones. The trap can be made of rigid materials like plastic, wood, or metal. It can also have a rough inner surface and openings for ecdysozoans to enter. The method for trapping ecdysozoans involves using the described trap.

Problems solved by technology

Pest eradication is time-consuming, expensive, and hard work with existing technologies.
However, mechanical control is time-consuming and requests many repetitions, most of the time without totally overcoming the infestation.
Chemical control uses pesticides or insecticides which provide various disadvantages: they may be toxic for humans, some are highly persistent and cause development of resistance to pesticides and / or insecticides.
Some of them are based on the use of natural or synthetic insecticides and thus present a risk to the health of the user.
However, insects are repelled by the contact between their legs, or their ventral side, and the sticky film applied on the floor.

Test

Experiment 1

Material and Methods

[0193]Two traps (one with smooth floor and one with rough floor) were placed in a plastic tray facing each other. The smooth floor was made of smooth plastic (polypropylene 55 μm, referred as smooth floor) from Pockets Din (Brony by doculine, 099007). The rough floor was made of sandpaper (240 grains / cm2, referred as rough floor). The roof of the traps was made of black paper coated with double-sided adhesive tape (AXTON®) on its interior surface. Twenty-five bedbug individuals (5 males, 5 females and 15 nymphs of all stags) were placed in the center of the tray. The number of individuals glued to the double-sided adhesive tape was noted after 15 hours.

Results

[0194]Results are presented in Table 1.

[0195]These results show that bed bugs significantly entered into traps with rough floor, compared to traps with smooth floor. On average, ove...

experiment 2

Material and Methods

[0196]A plexiglass plate comprising areas sanded with different densities of sandpaper (4000, 3000, 2000, 1000, 400, 280, 120, 80 and 60 grains / cm2) was used. Sandpaper of 4000 grains / cm2 provides a very fine sanding, while sandpaper of 60 grains / cm2 leads to important scratch on the plexiglass plate. The ease of bedbugs to travel on each sanded area was observed. Then the capacity of bedbugs to climb on the support when it is tilted was investigated.

Results

[0197]Bedbugs have great difficulty moving through plexiglass areas sanded with sandpapers of 4000 to 1000 grains / cm2 (they slide). However, the more the density decreases, the more bedbugs have facility to move, which is reflected by an increase of their travel speed (data not shown). When the plexiglass plate is tilted, bedbugs are not able to hold onto and slide along the plexiglass areas of 4000 and 3000 grains / cm2. From 2000 grains / cm2, bedbugs are able to hold on to the support even vertically.

experiment 3

Material and Methods

[0199]The same experiment as in Experiment 2 hereinabove was performed on two other materials with increasing roughness: sand paper and plastic rough-textured plastic.

Results

[0200]Bedbugs were found to slide on smooth materials and materials very slightly rough. The mobility of individuals increased up from a density of about 1000 grains / cm2 to 200 grains / cm2. Then, individuals have increasing difficulties in mobility on materials with a greater roughness, from 180 to 60 grains / cm2.

[0201]Therefore, the mobility of individuals to enter into the trap depends on roughness of the material. The results show that the most appropriate density increased up to 200 grains / cm2.

Abstract

A device (1) for trapping ecdysozoans, in particular insects and arachnids such as bedbugs, cockroaches, ants and spiders. In particular, the trap includes a sticky substance (7) on the interior surface of the roof (3) and / or of the walls (5b). Also, methods to trap ecdysozoans using the trap that includes the sticky substance on the interior surface.

Description

FIELD OF INVENTION[0001]The present invention relates to the field of pest infestations, in particular by ecdysozoans. More particularly, the present invention relates to a trap for catching ecdysozoans.BACKGROUND OF INVENTION[0002]Ecdysozoans are animals that grow through successive molts of the exoskeleton and that share characteristics of a multi-layered cuticle composed of organic material and appendages for locomotion. Ecdysozoans are the source of various pest infestations.[0003]Pest eradication is time-consuming, expensive, and hard work with existing technologies. In particular, ecdysozoans may hide in inaccessible places. Moreover, they are resistant to most pesticides and insecticides. After identification of the pest, two options are currently available: mechanical or physical control, and chemical control.[0004]Mechanical or physical control does not use pesticide or insecticide and is recommended to decrease and remove a maximum the parasitic load. Its principal advanta...
