Embodiment 1

[0027] Step 1: In the planting stage, when the crops are planted, 50% chlorantraniliprole seed treatment suspending agent is used for seed dressing, the weight ratio of the seed treating suspending agent and the seeds is 10g:100g, and the seeds are sown;

[0028] Step 2: In the monitoring and prevention stage, install the insect trap lamp in the area that needs to be controlled, put the insect attractant into the storage tank inside the insect trap lamp, and power on the insect trap lamp to make the insect trap lamp work normally;

[0029] Step 3: In the initial control stage, when the crops grow to the emergence stage, place the insect-repelling granules with repellent effect on the peripheral plants in the crop planting area, and the number of grains used for each crop is 50;

[0030] Step 4: In the mid-term control stage, spray the control agent evenly on the surface of the crops by means of spray control, plan and establish an artificial release base for noctuid parasitoids...

[0037] Step 2: In the monitoring and prevention stage, install the insect trap lamp in the area that needs to be controlled, put the insect attractant into the storage tank inside the insect trap lamp, and power on the insect trap lamp to make the insect trap lamp work normally;

[0038]Step 3: In the initial control stage, when the crops grow to the emergence stage, place the insect-repelling granules with repellent effect on the peripheral plants in the crop planting area, and the number of grains used for each crop is 80;

[0039] Step 4: In the mid-term control stage, use the spray control method to evenly spray the control agent on the surface of the crops, plan and establish an artificial release base for the noctuid p...

Embodiment 3

[0045] Step 1: In the planting stage, when the crops are planted, 50% chlorantraniliprole seed treatment suspending agent is used for seed dressing, the weight ratio of the seed treatment suspending agent and the seeds is 20g:100g, and the seeds are sown;

[0046] Step 2: In the monitoring and prevention stage, install the insect trap lamp in the area that needs to be controlled, put the insect attractant into the storage tank inside the insect trap lamp, and power on the insect trap lamp to make the insect trap lamp work normally;

[0047] Step 3: In the initial control stage, when the crops grow to the emergence stage, place the insect-repelling granules with repellent effect on the peripheral plants of the crop planting area, and the number of grains used for each crop is 100;

[0048] Step 4: In the mid-term control stage, use the spray control method to evenly spray the control agent on the surface of the crops, plan and establish an artificial release base for the noctuid...

Abstract

The invention belongs to the technical field of pest control, and particularly discloses a grassland spodoptera frugiperda control method which comprises the following steps: when crops are planted, selecting a seed treatment suspending agent for seed dressing, and sowing the seeds; the trap lamp is installed in an area needing prevention and control, and an attractant is put into a storage groove in the trap lamp; when the crops grow to a seedling emergence stage, throwing the insect-proof granules into cores of the crops; and finally, uniformly spraying the prevention and treatment agent on the surfaces of the crops in a spraying prevention and treatment manner. The corn essence and the maltodextrin are added into the attractant, fragrance emitted by the attractant can better attract the spodoptera frugiperda in cooperation with the main materials, a large number of the spodoptera frugiperda can be attracted to enter a trap lamp and killed before crops bear fruits, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a control method for Spodoptera frugiperda. Background technique [0002] Spodoptera frugiperda (scientific name: Spodoptera frugiperda) is an insect of the genus Spodoptera in the family Noctuidae of the order Lepidoptera. It damages crops in the larval stage, and completes a generation in about 24-30 days at 25°C. Adults are active at night, and the egg mass is usually laid on the back of the leaf. Usually, one egg mass contains 100-200 eggs, and the eggs are covered with scales. The eggs can hatch in 3 days at 25°C. There are 6 instars of larvae, and the body color and body length change with ages. The most obvious feature of larvae is that there are 4 black spots arranged in a square on the distal segment of the abdomen, and the head has obvious inverted "Y" pattern. Mature larvae mostly fall to the ground and use shallow soil to make a pupal chamber to pupate, and a fe...
