When should I hang a yellow roller trap?

As a non-toxic and environmentally friendly physical insect trapping tool, armyworm yellow belt is widely used in greenhouse vegetables, orchards, flower bases and other planting places. It uses the visual attraction of yellow to pests and traps flying pests such as aphids, whiteflies, wet fungus flies, leafhoppers and thrips. So, When should I hang a yellow roller trap?

It is generally recommended to hang the crop immediately after planting. At this time, the pests have not yet multiplied on a large scale, and the yellow sticky roll trap is laid in advance, which helps to achieve the management strategy of "prevention first". Through early monitoring, changes in insect conditions can be grasped in a timely manner and the risk of insect outbreaks can be reduced.

For the season of high incidence of insect pests, especially in spring and early summer, the density and number of hanging should be appropriately increased to enhance the booby trapping effect. If used for indoor crops, they can be laid all year round, but new belts should be replaced at regular intervals to ensure stickiness and effectiveness.

When the insect situation is serious or an outbreak has occurred, the yellow sticky roller trap can also be used in conjunction with other biological or chemical control methods to play an auxiliary control role. Especially in environments where the use of pesticides is restricted, the role of armyworm yellow band is particularly important.

Summary: Yellow insect roller trap should be laid at the beginning of crop planting, and the suspension time and number should be flexibly adjusted according to the insect dynamics, so as to achieve the ideal monitoring and control effect.
