Tobacco leafminer, also known as potato tuber moth, tobacco farmers said that it is distributed throughout the world, and there are also different degrees of tobacco handling areas in China. Larvae like to eat yellow tobacco and safflower tobacco; vegetables like to eat potatoes, eggplant, tomatoes and so on. The worm is mainly responsible for the growth of tobacco in tobacco, followed by tobacco seedlings, and also damages the growth point of late tobacco plants. After the victim's tobacco leaves are modulated, the latent marks are dark brown or gray-brown, causing the tobacco leaves to produce variegated colors. In the grading operation, the tobacco leaves are often ruptured and the broken cigarette rate is increased, thereby reducing the commodity grade and price. First, living habits Adult activity at night, copulating spawning, eggs are prolific on the front and back sides of the feet. Around the branch veins and base of the stem, the eggs are scattered and there are also 2 to 3 capsules produced in one place. Most of the eggs hatched in the early morning. The newly hatched worms started to move leaves on the leaves or stems for about 30 minutes. It usually takes 2 to 3 hours from the start of larvae to break into the leaves. A larva eats about 10 square centimeters of tobacco on average. The mature larvae climb out of the latent marks and fall down to the ground, and they are gray in the ground, in the leaves of the feet, in the depressions of the stems, or in the fallen leaves. Tobacco leafminers are larvae, cockroaches and other insects in the tobacco residues, eggplant straw, potatoes and other places overwintering. The infestation of solanaceous vegetables near tobacco fields is particularly serious. Generally warm in winter, is conducive to the occurrence of pests the following year. There are many kinds of natural enemies of the tobacco leafminer. There are 12 known parasitic bee species, 10 species of wasp species, 8 species of genus werep species, 4 species of predatory natural enemies, and 6 species of parasitic pathogens. In nature, these natural enemies have a certain inhibitory effect on the occurrence of tobacco leaf miner. Second, the prevention and control measures 1. Clean the pastoral autumn and early winter, completely remove tobacco leaves and leaves of Somalia near the plant debris, concentrated burned to reduce the source of overwhelming winter, reduce the incidence of pests the following year. 2. Use insect-free tobacco seedlings to take seedlings and carefully examine and remove the seedlings when transplanting. 3. Strengthen field management Combine cultivating and weeding, remove bottom leaves, and focus on treatment (burning or deep burial, flooding, etc.) to reduce larval, pupal, and egg status. 4. Chemicals Control pest occurrence period, can choose the following low-toxicity and low-residue pesticides such as 1% virtu 2000~2500 times or 1% Burmese ink preparation 300 times, or 1% chlorate 2000 times, or 1.8 % Destruction 3000 times. One of the above appointments is used interchangeably. Pests occur every 10 days, spray 2 or 3 times. 10 to 15 days before the harvest to stop medication.
