Problems solved by technology

However, since 1997, with the large-scale commercial planting of Bt genetically modified cotton, the use of broad-spectrum chemical pesticides in cotton fields has been greatly reduced, making the pricking and sucking method that was originally used to control the cotton bollworm Helicoverpa armigera (Hübner) The outbreak of the pest Lygus viridatus in the cotton field caused serious yield loss and spread to sunflower and other crops as well as jujube, grape, apple, peach, pear and other fruit trees. It has become a major problem affecting the safe production of various crops in my country

Embodiment 1

[0019] Example 1 The effect of different types of trapping methods on the trapping effect of Lygus aureus adults

[0020] From 2010 to 2012, the trapping effect of 4 kinds of aromatic compounds (m-xylene, butyl acrylate, butyl propionate and butyl butyrate) on the adults of Lygus lucidum was studied by sticky board. First insert a 2.5m-long bamboo pole into the soil and keep it vertical, then staple the white sticky board (18×25cm, Henan Jiaduo Technology Industry and Trade Co., Ltd.) Fix the plastic card board on the bamboo pole so that the bottom is even with the top of the crop. The distance between two adjacent bamboo poles is 15m, and the glued side of the sticky board faces south. Hang 1ml of plant volatiles diluted with agar (100μg / μl) or the control in the center of the sticky plate, and after 3 days, the trapping of the green ligudrum on the sticky plate was identified and counted. Each plant volatile fraction was replicated 16 times. The result is as figure 1 Sho...

Embodiment 2

[0023] The preparation method and application of the botanical attractant of embodiment 2 Lygus chlorophylla adults

[0024] In 2013, a barrel trap was used to systematically evaluate the trapping effect of 4 kinds of aromatic compounds mixed in pairs in different proportions on Lygus japonica adults. A total of 5 ratios were set, followed by mass ratio 1:0, 3 :1, 1:1, 1:3 and 0:1, the field experiment method is the same as "Example 1". After 3 days, the identification and statistics of Lygus spp. trapped in the barrel trap were carried out. Each treatment was repeated 6 times. The results are shown in Table 1.

Abstract

The invention relates to the plant protection field and in particular provides a plant source attractant composition for adult green plant bugs. The plant source attractant composition is characterized in that firstly, the plant source attractant composition is prepared from butyl acrylate and butyl propionate with mass ratio of 3:1; or secondly, the plant source attractant composition is prepared from butyl acrylate and butyl butyrate with mass ratio of 1:1. The invention also provides application of the plant source attractant composition for the adult green plant bugs in plant protection. The plant source attractant composition for adult green plant bugs has simple preparation and application methods, low price and good pollution-free trapping effect.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to a plant-derived attractant composition for the green ligud bug adult and application thereof. Background technique [0002] In the past, the green ligus Apolygus lucorum (Meyer-Dür) has always been regarded as a minor pest on crops such as cotton, with a relatively low degree of damage and little need for special control. However, since 1997, with the large-scale commercial planting of Bt genetically modified cotton, the use of broad-spectrum chemical pesticides in cotton fields has been greatly reduced, making the pricking and sucking method that was originally used to control the cotton bollworm Helicoverpa armigera (Hübner) The outbreak of the pest Lygus viridatus in the cotton field caused serious yield loss and spread to sunflower and other crops as well as jujube, grape, apple, peach, pear and other fruit trees. It has become a major problem affecting the safe production of v...
