The scientific name Tetranychus cinnabarinus (Boisduval) belongs to the order Acrididae. Alias ​​cotton red spider, cotton leafhopper, red leafhopper. Synonyms Telarius. Distributed throughout the country.
In the past, the host had mistakenly designated the red decaline of cotton and vegetables as cotton leafhoppers. Actually, the cotton leafhopper is a complex population of more than 3 species including Cinnamomum vulgaris and E. urticae, mainly responsible for corn and sorghum. , millet, sunflower, mulberry, straw, beans, cotton, dates, citrus, cucumber and so on.
Traits with truncated leaves.
The morphological characteristics of adult females are 0,48-0.55mm in length, 0.32mm in width, and oval in shape. The body color often varies from host to host, mostly rust-red to deep-red, with one pair of dark spots on each side of the body. Skin striae triangular to semicircular. The male body is 0.35mm long and 0.2mm wide. The front end is nearly circular, slightly pointed at the abdomen, and the body color is lighter than that of the female. Egg length 0.13mm, spherical, light yellow, slightly redder before hatching. The cubs have 3 pairs of feet. If çž’4 pairs of feet are similar to Chengyu.
Life habits are 10 to 20 generations (increasing from north to south). Overwintering species and sites vary from region to region. In North China, female adults grow in weeds, litter and earth seams. The wintering occurs in the weeds and the bark seams; wintering occurs in Sichuan, where the females become weeds in weeds or peas, broad beans and other crops. When the temperature in Hunchun is above 10°C, it begins to multiply. In March-April, weeds were first eaten on weeds or other hosts. After the fruit trees germinated, they migrated to the fruit trees one after another. Each of the females spawned 50-110 eggs and prolific in the leaves. The egg period is 2-13 days. The developmental duration of the young larvae and Ruoqiang is 5 to 11 days, and the worm life span is 19 to 29 days. Can be parthenogenetic, mostly male offspring. Young cubs and early raccoons are not active. In the later period, Ruoqiang was lively and bulimia, and had the habit of climbing upwards. First damage the lower leaves and then spread upward. When there are too many breeding numbers, they often cluster at the tip of the leaf, rolling down the ground, being blown away by the wind and crawling around. The starting temperature for the development of C. verrucosa is 7.7-8.8°C, the optimum temperature is 25-30°C, and the optimum relative humidity is 35%-55%. Therefore, the high-temperature and low-humidity of June-July will be a serious problem, especially in dry years. occur. However, if the temperature exceeds 30°C and the relative humidity exceeds 70%, it is unfavorable for its reproduction, and heavy rain has an inhibitory effect. There are more than 30 natural enemies.
Control methods (1) Agricultural control. Eradicate field weeds and remove stubborn leaves and leaves. (2) There are more than 30 species of natural enemies in this species, and attention should be paid to protection and natural enemies. (3) Chemical control. At present, bionic pesticides have a special effect on the cinnabar leafhoppers and the two-leafhoppers. The 1.8% aconazole EC is 2000 times effective, has a long duration, and has no phytotoxicity. In addition, we can use 20% chlorimethanol 2000 times solution, 20% 2000 times the emulsifiable solution, 40% 25% solution of mercaprol EC, 20% dimethylformamide EC 1000-1500 times, 10% Uranus EC 6000-8000 times liquid, 10% imidacloprid WP 1500 times, 1.8% EFOT (BA-1) EC anti-insecticide acaricide 5000 times, 15% oxime Cattle Star) EC 2500 times, 20% compound Liuyangmycin EC 1,000-1500 times, control 2-3 times.
Electric Heating Cape is quite similar to Electric Over Blanket. Their main difference is the shape. Heating cape is more like a clothes.
People can wear it during a cold night, and choosing the suitable heat setting to keep warm, as it has adjustable 4 temperature settings.
Heating cape is also not suggested to be used during sleeping.
It also has the function of automatic shut off, normally it is set up by 2 hours, which is approved to be the best for human health.
