Problems solved by technology

[0004] Although there are also some sex attractants that use rice leaf rollers for biological control, the sex attractants of rice leaf rollers are very poor in field attractants, and cannot reach the purpose of preventing and treating rice leaf rollers, and Sex pheromones mainly act on males and rarely attract females

Embodiment 1

[0020] A rice leaf roller attractant, comprising:

[0021]

[0022]

[0023] After the above components are fully mixed and uniform, the slow-release rubber is soaked into the above mixture, and after fully soaking, the lure is obtained and can be used for the following examples.

Embodiment 2

[0025] A kind of application of rice leaf roller attractant, the application process is as follows:

[0026] In this example, the following method is used to evaluate the attractant effect of the attractant prepared in Example 1 in the field: when carrying out field control, the prepared lure core is used with the boat trap on the market, and the bracket is used to The boat trap is suspended in the rice field (the height is preferably 20cm below the rice leaf surface).

[0027] Field lure effect evaluation:

[0028] With the attractant of the present invention in conjunction with the boat trap as the experimental group, the lure core soaked in liquid paraffin combined with the boat trap is a control group; the two are suspended in the paddy field respectively, and the rice verticals induced by each trap are recorded every two days. The number of leaf rollers, compare the effect of attracting insects between the two. At the same time, the number of traps was investigated ever...

Embodiment 3

[0042] Indoor lure effect evaluation:

[0043] The H-type olfactometer device used in this embodiment is as follows: figure 1 As shown, the device includes two containers with covers, and the two containers are communicated through circular tubes; the containers have ventilation holes, but insects cannot pass through them.

[0044] In the two containers of the device, put the lure core soaked by the attractant and the lure core soaked by liquid paraffin respectively, and 30 rice leaf rollers are placed in the circular tube. During the experiment, the light was turned off first, and the selection results of the rice leaf roller were recorded 1 hour later. The experiment was repeated 8 times.

[0045] The selection results of rice leaf roller are as follows

[0046] The average number of heads selected by the rice leaf roller (piece)

[0047] test group control group 26 4

[0048] The results showed that the attractant had a very significant attracting e...

Abstract

The invention belongs to the field of preventing and control of pests, and particularly relates to a rice leaf folder attractant and application. The rice leaf folder attractant is characterized in that the used substances are natural substances in the nature, or adopt the artificial synthesizing type of natural substances, or the artificially synthesized accepted safe and poisonless inert substances, so as to slowly and continuously release the attractant. The rice leaf folder attractant comprises an inert hydrophobic controlled-release carrier, and the volatile aroma is continuously releasedfrom the carrier, so as to trick and attract the rice leaf folder to get close; then, the insects are killed by poisonous baits, insect sticking plates and the like, so as to effectively control thenumber of harmful target (rice leaf folder), control the degree and scope of rice leaf folder hazard, and reach the purposes of output increase and income increase in agriculture.

Description

technical field [0001] In the field of pest control, the invention specifically relates to an attractant for rice leaf rollers and its application. Background technique [0002] The rice leaf roller is an important migratory pest of rice in my country and Southeast Asia. The larvae roll the leaves vertically to feed, leaving only the epidermis and forming white streaks, which affect the photosynthesis of the crops, generally causing a 20%-30% yield reduction. When it happened, the paddy fields were dry and white, and even the grains were not harvested. Since 2000, the occurrence of this insect has become more and more serious in my country, with an average annual occurrence area of ​​more than 20 million hectares and an average annual grain loss of 760,000 tons. Most of the rice areas in the south suffered from severe outbreaks, covering an area of ​​25.3 million hectares, the largest occurrence in the past 20 years. [0003] At present, the control of the rice leaf roller i...
