[0004] Citrus psyllids tend to be tender and yellow. The traditional method of trapping citrus psyllids is to use yellow boards to trap them, but the trapping effect is not obvious.
In the prior art, a composition is also used to trap citrus psyllids, and the trapping effect is better than that of yellow boards. However, in the field of trapping citrus psyllids relying on the sense of smell, it is still necessary to find a more significant trapping effect. Chemical material

The invention discloses a chemical substance for trapping diaphorina citri. The chemical substance comprises 0.1-100muL / mL of caryophyllene, particularly 10muL / mL of caryophyllene. The diaphorina citri does not have obvious taxis to mixed volatiles of caryophyllene, trans-2-vinyl aldehyde, humulene and n-hexaldehyde, and adult diaphorina citri has obvious positive taxis to 10uL / mL of caryophylleneand can be trapped by using the 10uL / mL of caryophyllene.
Description
technical field [0001] The invention relates to the field of plant disease and insect pest control, in particular to a chemical substance for trapping citrus psyllids and a trapping method. Background technique [0002] Plant volatile substances are important semiochemicals between plants and insects. Insects can make corresponding behavioral responses based on chemical information from host plants. By sensing volatile substances released by plants, insects can avoid poisonous plants and find suitable food, mates, and places for survival and reproduction. [0003] The citrus psyllid, Diaphorina citri Kuwayama, is one of the important pests in citrus production, and it is the vector of citrus huanglongbing (Candidatus Liberibaeter asiatieu, Las) and American species (Candidatus Liberibaeter amerieanus, Lam). [0004] Citrus psyllids tend to be tender and yellow. The traditional method of trapping citrus psyllids is to use yellow boards to trap them, but the trapping effect i...
