A specific colored sticky card that effectively trapped adults of Plutella xylostella

<p><i>Plutella xylostella</i> is a major vegetable pest in the world. In this study, when a single colored sticky card trapped a small number of adults of diamondback moth in one week in one greenhouse, and the maximum number on single sheet did not exceed 100, the sticky card C6 showed a strong trapping effect, which was significant higher than other colored sticky cards. When a single colored sticky card trapped more adults of <i>P. xylostella</i> in one week in one greenhouse, and the maximum number of single sheet exceeded 100, the colored sticky cards C1-8, 11, and 13 all exhibited relatively strong trapping effects. In short, the adults of <i>P. xylostella</i> preferred bright colors, and the darker colored sticky cards had relatively poor trapping effects. For the prevention and control of pests, choosing the right colored sticky card will do more with less.</p>
