Technical field
The invention belongs to agriculture field, specifically, is related to a kind of killing trapping device of effectively prevention and control spotted wing drosophila harm.
Background technology
Spotted wing drosophila (Drosophila suzukii) is a kind of primary pest that many orchard crops face, including：Cherry
Peach, blueberry, nectarine, strawberry, red bayberry, grape etc..Spotted wing drosophila appears in Japan and China earliest, has invaded its other country again recently
Family, for example, US and European.Since spotted wing drosophila is from the inside of the fruits such as cherry, blueberry, nectarine, strawberry, red bayberry, grape
Fruit is destroyed, so the exterior spraying insecticide even in these fruits also can not protect these fruits not to be subject to spotted wing drosophila
Harm.Further, since spotted wing drosophila is just to start to endanger fruit when the fruit of orchard crop is soon ripe, and the period one
As be in harmony again and meet fruit close to the collecting period, also should not be again to fruit spraying insecticide so in order to ensure the safety interval of pesticide.
So that harm of the spotted wing drosophila to industries such as cherry, blueberry, nectarine, strawberry, red bayberry and grapes is difficult to eliminate.
The method for traping spotted wing drosophila was all tested in the country such as US and European, these countries have been developed for
Attractant.The attractant is mixed by vinegar, sugar, wine and yeast.But it was verified that the attractant cannot be to spotted wing drosophila
The purpose effectively controlled is played in harm.In fact, the effect for the attractant trapping spotted wing drosophila being made of vinegar, sugar, wine and yeast
It is poor, it can even increase the extent of injury to orchard fruit sometimes.Although the appearance of such case be due to attractant in itself
With effect, but spotted wing drosophila is not partial to enter in trapper.The reason is that spotted wing drosophila instinct and not liking
Other spaces or container are entered by hole, because unknown place is dangerous for their part, only very small part spot wing
Drosophila can take a risk to enter.Therefore can only be used in the U.S., the method for this kind of trapping spotted wing drosophila of expert advice in orchard periphery, and
And could be used when there was only spraying insecticide at the same time, also so that it, which can only be used as monitoring instrument, carries out detecting and reporting pest information.
