1. Hazard 1.1 The adult larvae and larvae can be harmed. The female adult flies, stabbing the plant leaves, feeding and spawning, larvae sneak into the leaves and petiole hazards, producing irregular serpentine white worms, chlorophyll is destroyed, affecting photosynthesis, causing damage to the leaves, causing flower buds, The fruit was burned and severely damaged. In the early stage of Liriomyza sativae, the insect tract was irregularly linear, and the terminal of the worm was often broadened to be different from the tomato leafminer. The affected field is subject to a rate of 30-100%, a 30-40% reduction in production, and a serious failure.
1.2 Adults of Liriomyza huidobrensis use the ovipositor to produce eggs in the leaves. The hatching larvae sneak into the mesophyll between the leaves and the epidermis, eating the ribs and veins, and the leaves are transparent plaques, causing the seedlings to die. Destructive. The larvae often form a submerged tract along the veins, and the larvae also feed on the sponge tissue in the lower layer of the leaves. The stalks are often incomplete from the leaf surface, unlike the Liriomyza sativae.
1.3 L. The terminal of the insect tract is not obviously widened, which is a special evidence that the worm is different from Liriomyza huidobrensis, Liriomyza huidobrensis, and Liriomyza sativae.
1.4 The larvae of the larvae of the larvae of the larvae of the larvae of the larvae, the foraging of the mesophyll leaves the upper epidermis, forming a tortuous tunnel, affecting the growth of vegetables After the peas are damaged, it affects the pods and the seed quality and yield.
2. Comprehensive control method 2.1 Low-temperature freezing and drying ridges Before the seedlings are planted in winter in January, the sheds are exposed to the low-temperature environment for 7-10 days, naturally frozen, and the overwintering insect source is eliminated.
The high temperature shack is to seal the shed for 7-10 days when the high temperature is changed in summer. The specific method is not to remove the remaining residual plants after harvesting the sorghum crops, that is, the sheds are all closed, and the shacks are not opened, so that they are sunny. The temperature reaches 60 ° C -70 ° C, killing a large number of pest sources. When the treatment is completed, the residual strain in the shed is eliminated, which saves labor and labor, and prevents the spread of the insect source to the open field.
2.3 Covering the insect net To set up an insect net at the vents of the autumn and spring protection sites to prevent the exchange of insects in the open field and the shed.
2.4 Hanging yellow plate to trap adult insects, erect yellow plate in the protective land to trap the adult larvae in the protected area. If you can keep the hanging height of the yellow plate at 20 cm above the growth point of the crop and keep the adhesion of the yellow plate, you can receive it very much. Good results.
2.5 chemical control
2.5.1 Smoke agents smoked and killed adults. That is to say, when the quantity is large in the protected area, the specific method is to use 500% of the 10% dichlorvos agent per mu, or the fenvalerate vinegar (according to the indicated amount) to smoke the adult, which is effective, but generally needs to be used continuously 2- 3 times.
2.5.2 Foliar spray to kill larvae. Spraying the foliage with plant-derived insecticides and high-efficiency and low-toxic pesticides: if it is a Liriomyza sativae and a tomato leafminer, it needs to spray on the front of the leaf. If it is a southern blotch, it needs to be positive and negative on the leaf. Spray on both sides. The specific agents are 3000 times solution of diflubenzuron, 2500 times solution of chlorbenzuron, 500 times solution of tobacco, 500 times of phlegm, 3,000 times of avermectin, and 3000-5000 times of avermectin.
