Problems solved by technology

[0003] In the prior art, the most commonly used measures to prevent and disinfect citrus psyllids are to use chemical drugs such as cyfluthrin, imidacloprid, and thiamethoxam, but these drugs are difficult to use due to problems such as drug resistance, safety, and persistence. has certain limitations
Moreover, because the citrus psyllid reproduces rapidly, has a large number, and eats frequently, many drugs cannot defend against this type of pest for a long time.
In addition, the larvae of citrus psyllids secrete wax to protect themselves, block the damage of drugs, and reduce the effect of drugs
Therefore, it is difficult to completely control the harm of such pests to fruit trees by simply relying on chemical drug control.

[0025] Example 1Z,3 Hexenyl Z,3 Hexenoate Attraction to Citrus Psyllid

[0026] The yellow armyworm board was selected as a screening tool for a series of candidate attractant compounds for citrus psyllids. Candidate attractant compounds are listed in Table 1.

[0027] Table 1 List of candidate attractant compounds

[0028] Z,3 vinyl alcohol Z,3 hexene acetate Z,3hexenyl Z,3hexenoate Alpha-ionone beta-ionone Methyl Salicylate Nonanal D-Limonene

[0029] 1. Attraction Assay for Candidate Compounds

[0030] The compounds in Table 1 were mixed with mineral oil in a weight ratio of 1:4 and heat-sealed in a PVC pipe, the inner diameter of the pipe was 2 mm, the pipe length was 50 mm, and the wall thickness was 0.5 mm. The mineral oil was purchased from Zhejiang Zhengxin Petroleum Technology Co., Ltd. The actual fillable volume in the tube after heat sealing is about 125 microliters, ie, the volume is about 107 mg. Thus, each test...

Abstract

The invention provides a diaphorina citri attractant as well as a controlled release system and application thereof. The application of the Z, 3-hexenyl Z, 3-hexenoic acid salt as the diaphorina citri attractant is disclosed for the first time, and the Z, 3-hexenyl Z, 3-hexenoic acid salt can be used for attracting diaphorina citri and is remarkable in attracting effect, so that the diaphorina citri can be accurately attracted and killed, the number of field populations of the diaphorina citri can be reduced, and the diaphorina citri attractant can be used for preventing and treating the diaphorina citri, monitoring insect conditions and the like. The insecticidal composition does not harm beneficial insects, human and livestock, crops and natural enemies, target pests do not generate resistance, and the insecticidal composition has the advantages of being natural, environmentally friendly and the like.

Description

technical field [0001] The present invention relates to the technical field of crop disease and insect pest control, in particular to an attractant for citrus psyllid and a controlled release system and application thereof. Background technique [0002] Citrus psyllid (Diaphorina citri) is a major pest of Rutaceae crops, which can damage the shoots and leaves of navel oranges. For example, adults often feed on shoots and leaf backs, while larvae flock to feed on shoots and leaves. The infected young shoots and buds dry up and shrink, and the new leaves become twisted and deformed. In addition, the larvae often excrete white flocculent secretions, covering the activity of the worms. Citrus psyllids can also induce soot disease, leading to weakened trees and reduced yield and fruit quality. In addition, the citrus psyllid is the main transmission insect of the citrus bacterial disease Huanglongbing, which is extremely harmful to citrus production. In particular, even a few...
