Embodiment Construction

[0031] Carry out an orthogonal test on conditions such as complex proteolysis substrates and products, and select the best plan. The factors involved in the orthogonal test are as follows:

[0032] (1) Composite hydrolysis substrate: the composition ratio of soybean protein and brewer's yeast protein is 1:1, 1:3, 1:9;

[0033] (2) Preservative content: 0.5, 1.0, 2.0;

[0034] (3) Spinosad content: 0.01, 0.05, 0.1;

[0035] (4) Final pH of hydrolyzate: unadjusted, 3.5, 4;

[0036] The hydrolytic enzyme is acid protease, the liquid-solid ratio of the enzyme is 10:1, the total amount of enzyme added is 5000 (U / g), the hydrolysis temperature during the hydrolysis reaction is 50° C., and the hydrolysis is 2 hours.

[0037] Table 1 shows the four factors and their values ​​that need to be studied in the orthogonal experiment.

Abstract

The invention discloses a bactrocera dorsalis hendel attractant, wherein the prescription of the attractant is a hydrolysate obtained by enzyme hydrolyzing soy protein and saccharomyces verevisiae protein according a certain ratio under some condition. The attractant not only is good for the environmental protection and the fruit safety, but also can prevent from environment pollution, and can not threaten human health and natural enemy of the bactrocera dorsalis hendel. The attractant has simple preparation method and low preparation cost, and can lead the hydrolysate to stably keep higher attractive force. The attractant has good attractive function to the female and fame bactrocera dorsalis hendel, thereby being capable of controlling the amount of species group of the bactrocera dorsalis hendel, reducing damage rate, and having good popularization meaning.

Description

technical field [0001] The invention belongs to the field of pest control, and in particular relates to an attractant for Bactrocera dorsalis. Background technique [0002] Bactracera dorasalis is a worldwide quarantine pest. It has a wide range of memory and strong reproductive ability. It can harm more than 250 kinds of fruits and vegetables, vegetables and flowers in 46 families such as guava and mango. It is a destructive pest. At present, it has caused serious economic losses to the fruit and vegetable industry and the flower industry in many countries. [0003] At present, the following methods are mainly used for the detection and control of Bactrocera dorsalis at home and abroad: [0004] 1. Chemically synthesized attractants: At present, it has been found that various chemical substances such as methyl eugenol, decoy ketone, and methoxybutyrophenone have a certain attractant effect on Bactrocera dorsalis, among which methyl clove is the most widely used phenol and...
