Yellow board

from Wikipedia, the free encyclopedia
Yellow panel between balcony plants

Yellow boards or yellow stickers , also generally glue boards, color boards, insect boards or yellow traps, are yellow cardboard or plastic boards provided with adhesives which are mainly used for pest control and, in the case of individual pests, also for pest control . There are also adhesive boards in other colors such as white ( white board ), green, red or blue. The latter is also known as the blue board .

purpose

Used yellow panels especially for early detection of flying insect pests such as cherry fruit , cherry fruit fly , Green Rebzikade , whiteflies , winged aphids, carrot fly , leafminer , fungus gnats , asparagus fly , wood borers , Kohlstängelrüssler , pollen beetles and many others. In living spaces in particular, it is also possible to combat insect pests if there is little infestation. In this way, at best, the use of pesticides can be dispensed with.

nature

Yellow-colored boards made of cardboard or yellow plastic are used as the basis for yellow boards. These are coated with a colorless adhesive.

The composition of the used adhesive , the manufacturer makes Russell IPM following information: the material that is used in the adhesive is mainly composed of polymers petrochemical origin, which give the product its tackiness. However, many manufacturers have different makes on the market. One type of board is only coated with polyisobutylene . These boards feel wet and do not dry out. Another chalkboard is coated with a mixture of polyisobutylene and other thermoplastic plastics, hot-melt adhesive mentioned. This coating is very similar to the glue on the back of self-adhesive labels and not as sticky as the first type. The Rebell type yellow boards are made of polystyrene , are colored with cadmium-free paints and coated with insect glue. The adhesive can be washed off with pure gasoline. The boards can be reused.

The toxicity of all adhesives used is negligible. They have a low irritant effect on the skin and are normally even allowed to come into contact with food. These adhesives are also used, for example, for brand labels on fruit .

Different colored variants

Different hues attract different pests. Green glued plastic sticks (stick glue traps) are used, for example, to monitor the asparagus fly by making them look similar to growing asparagus stalks. White trapping boards are suitable for checking the apple saw wasp . The traps used for the wood drill are dark pink. In the case of some thrips species, the pest population can be reduced so that no treatment with insecticides is necessary using the blue-colored boards. However, the thrips are not 100% recorded.

Geometry variants

In order to make the boards more visible to the insects, they can be plugged into each other at right angles. To improve the catching results, carrot fly traps are placed in a wooden post with a prepared slot at an angle of 45 °. Some yellow panels also have a printed grid to simplify counting during pest control. Another variation is glue rings that are placed around the shoot of the plant.

Use of attractants

In an experiment, a cherry-colored ball with an attractant was built into the plastic yellow plate. The attractant anisaldehyde is used for thrips , which improves catch numbers when combating.

Place of use, functionality and effect

Yellow stickers after the “harvest” on a peach tree

Yellow stickers that are hung up or stuck in the plant substrate are intended for professional and private use. In different versions, they can be used in any closed rooms such as living rooms, greenhouses or winter gardens as well as in the open air or on balconies. Outdoor use is possible if boards, plastics and adhesives are insoluble in water and largely heat-resistant.

The way it works is based on the insects' affinity for the colors yellow, blue, green or white; if they touch the glue layer on the board they stick. The number of animals caught does not indicate the exact severity of the infestation, it is only an indicator of the first occurrence and is suitable for recording the respective intensity of the infestation. For this purpose, the catch panels, which are always the same size and color, are checked, counted and replaced with new panels every week. For this purpose, the yellow panels are fixed 10 cm above the stand up to a maximum of 30 cm above the plant surface (canopy).

The action against whiteflies in tomato culture was shown in Sicily, where good control effects were observed with 5 m² panels. However, the use of yellow panels as a control measure against the cherry fruit fly is unsuccessful. Good results are achieved against rhododendron leafhoppers, but without completely eliminating the infestation. Many other insects, especially flies, are also caught here.
