Problems solved by technology

[0005] However, many problems have been found in the application of food attractants: (1) There are very few effective insecticides for adults of lepidopteran pests (Socorro et al., 2010), and the control effect of adults after feeding on food attractants is not good. (2) Some agents have good toxic effects on adults, but are not quick-acting, and can continue to lay eggs and reproduce for a period of time after feeding, which in turn will cause harm to offspring larvae; ( 3) Adults can continue to fly and spread between crops after eating the medicaments with poor quick-acting properties, which will easily bring the pesticides attached to the worms to the crops, causing the problem of excessive pesticide residues in agricultural products such as fruits and vegetables; (4 ) Methomyl and other pesticides commonly used in food attractants are highly toxic, which can easily lead to food safety problems for agricultural products

Embodiment 1

[0019] The preparation of embodiment 1 quick-acting insecticide

[0020] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] 1. Raw materials:

[0022] Chlorantraniliprole (95%, DuPont (Shanghai)), food attractant (Obali, Shenzhen Bailebao Biological Agriculture Technology Co., Ltd.)

[0023] 2. Preparation method:

[0024] Dissolve 100 mg of chlorantraniliprole into 1 L of food attractant to obtain an insecticide with a content of 100 mg / L of chlorantraniliprole.

Embodiment 2

[0025] The preparation of embodiment 2 quick-acting insecticides

[0026] The difference between this example and Example 1 is that 1 mg of chlorantraniliprole was dissolved in 1 L of food attractant to obtain an insecticide with a content of 1 mg / L of chlorantraniliprole.

Embodiment 3

[0027] The toxicity test of embodiment 3 chlorantraniliprole

[0028] Toxicity determination adopts the method of feeding poisonous nutrient solution, select 3-5 day-old adults and move them into plastic cups (upper diameter 68mm, height 74mm, bottom 48mm), and put them in honey water or honey water containing different concentrations of chlorantraniliprole. Cotton balls were put into plastic cups respectively as supplementary food for adults of cotton bollworm or Spodoptera litura, and 2 adults were placed in each tube, and 10 adults were treated for each treatment, repeated 3 times, and the result of inspection after 24 hours was recorded as die.

[0032]

[0033] The toxicity test results of 15 kinds of 26 kinds of insecticides to adults of cotton bollworm showed that the tested diamides (chlorantraniliprole, flubendiamide)...

Abstract

The invention relates to the field of pest control, and specifically provides a quick-acting insecticide for adult lepidopteran pests. The insecticide is a food attractant containing chlorantraniliprole, and the content of chlorantraniliprole in the insecticide is 1-100 mg / L. It has high toxicity to cotton bollworm and Spodoptera litura, good quick effect, and is safe to non-target organisms and the environment.

Description

technical field [0001] The invention relates to the field of pest control, in particular to a quick-acting insecticide for adult lepidopteran pests. Background technique [0002] Cotton bollworm [Helicoverpa armigera (Hübner)] and Spodoptera litura (Fabricius) belong to Lepidoptera Noctuidae, both of which are important agricultural pests worldwide. They not only affect the yield of food, vegetables and economic crops, but also cause Its quality deteriorates. [0003] At present, chemical control is still an important means of controlling the two kinds of pests. Since cotton bollworm and Spodoptera litura are pests mainly larvae, the past control method is to spray the larvae or eggs. However, with the emergence of pesticide resistance, farmers are forced to increase the amount of pesticides to control pests, which seriously threatens the safety of agricultural products and the ecological environment. [0004] Volatiles produced by host plants play an important role in the...
