In recent years, with the accelerating pace of structural adjustment of the planting industry, the planting area of ​​special economic crops such as lotus root, alfalfa, and vegetables has continued to expand. Soybeans, peanuts, and other crops still have larger planting areas. The occurrence and harm of Spodoptera litura is increasingly rampant. Local places have risen from major pests to major pests. Spodoptera litura can harm lotus, konjac, cabbage, radish, cabbage and other vegetables, as well as solanaceae, cucurbitaceae, leguminous, onion, scallion, spinach, sweet potato and other crops of more than 99 families and more than 290 species, can cause serious damage to the hillock Lost.
Spodoptera exigua prefers a high temperature and high humidity climate, showing an intermittent local outbreak. The severe period is from July to August. In particular, the occurrence of many crops that grow in lush crops is a serious problem. The rainfall from May to June in most parts of our province is higher than in previous years, and the higher temperature is conducive to the reproduction and occurrence of Spodoptera litura. It is necessary to guard against the outbreak of Spodoptera litura.
Using light to seduce the adults of the Spodoptera litura, the grayish-brown tan has many gray-white markings and line patterns. The wide-brimmed twill which consists of three grayish white horizontal lines in the middle of the wings is the most striking. It usually takes 5-6 generations, even 6-7 generations, and the generations overlap. In areas where the area is relatively large, a frequency-vibration insecticidal lamp can be installed on 40-50 acres, and the village or natural area can be used as a unit to unite the organization, raise funds, and manage it in a unified manner. This method has a good insecticidal effect and is worth promoting. It is also possible to seduce by artificial light in a small area, for example, 1 lantern per 5 acres, a basin under the lamp, and a small amount of diesel oil on the water. This method is more familiar to farmers and has a low cost.
The promotion of sweet and sour trapping and killing is based on the nocturnal activities of adults and has strong tropism for black light and sweet and sour liquid. It has strong flying ability and can be used for long-distance movement. In the period of adult growth, use 10 parts of sugar, 1 part of wine and vinegar, add 8 parts of water, mix into a mixture, and add it to the inside, add a little trichlorfon, and put it in the field at night; ~ 15 cm, 1 æ¯ per mu, recovered in the morning; each generation of the moth period even for about 10 days. Or use the twigs of the yang twigs to dip 500 times of dipterex liquid, 7 to 8 sticks each, each about 50 centimeters long; shoots upside down, slightly above the vegetable strains, hung on the bamboo poles in the field; 10 per mu; Can kill a large number of adults, which greatly reduces the occurrence and harm of larvae.
Artificial egg collection and larval capture due to spawning of Spodoptera litura concentrated on the bifurcation of the leaf blade at the back of the middle part of the plant. After hatching, the larvae had a false death. Before the 2nd instar, the leaves were fed with leaf meat near the egg and the damaged leaves were sieved. Easy to find. Therefore, it is possible to remove the "window leaf" (having eggs and insects) before the egg stage and the newly hatched larvae are not dispersed, and treat them in a concentrated manner to kill the eggs and larvae.
Grasp the control of drug use in the younger age In view of the 3rd instar larvae began to disperse the hazards and enter the overeating period after the 4th instar, it is necessary to seize the medication when not dispersed before the 3rd instar. Spodoptera litura larvae are feign dead and sensitive to sunlight and should be applied early in the morning or early evening. Can be used 2.5% Kung Fu EC 3000 times, 5% Ruijinte floatator 1000 times, 10% Distill the EC 2500 times, 75% Ravine WP 1000 ~ 1500 times, 25% W PhO 1000 to 1500 times liquid, 18% insecticidal double water 500 times liquid, 10% Doraemon suspension 600 to 800 times liquid, 20% eradication emulsion or 50% phoxim EC 2000 times spray; Mu with 15% vegetable cream EC 36 ml (3 bags), watered 50 kg on the positive and negative sides of the leaf spray, can cure old larvae.
In the winter, the mature larvae of the adult Spodoptera litura can be ploughed into the soil in winter. They can plow through the soil in the winter, eradicate the weeds in the field, clear the pasture, eliminate the overwintering insects, and reduce the number of occurrences in the coming year.
