The insect pest forecast lamp can use solar energy to power, and in the absence of supervision, it will automatically turn on the lights at night and turn off the lights automatically during the day to automatically complete various kinds of plants such as grain, cotton, oil, vegetables, fruit, flowers, grass and other moths. Butterfly pests are used for attracting insects, killing insects, collecting and packing, and are an insect trapping lamp. With the continuous increase of the area of ​​cotton, the layout of crops is relatively single, and the occurrence of cotton pests and diseases is becoming increasingly serious. In particular, the occurrence of insect pests has increasingly become an important factor affecting and restricting cotton production. The comprehensive prevention and control of pests has become the most pressing problem to be solved on the plant protection front, and pest monitoring is particularly important. The mastery of pest occurrence provides an important scientific basis for formulating pest control strategies. The pests and diseases of cotton are mainly divided into diseases and insect pests, and the specific diseases and insect pests are briefly described separately. The main diseases of cotton include cotton blight, cotton anthracnose, and cotton wilt disease. 1. Bacterial seedling blight is harmful to cotton. After the cotton is sown and the seeds germinate but not yet unearthed, it can cause bad shoots due to blight. After the cotton seedlings are unearthed, yellowish-brown lesions appear on the base of young shoots near the ground, which gradually enlarge, sag, and rot, and can be severely spread around the stems. The depressions are deepened, the color is dark brown, and cotton seedlings die. The leaves of diseased plants generally do not show special symptoms, but only show wither; but there are also cotton seedlings that suffer from damage, there are melasma on the cotyledons, and finally the lesions rupture, fall off and form perforations. Damaged cotton seedlings and surrounding soil often have mycelium adherence. In rainy years, cotton buds at the flowering and budding stage can also suffer damage, dark brown spots appear at the base of the stem, the surface of the stem rots, wood fibres are exposed, and death can be severely broken. Affected sites, sometimes tumor-like lesions. 2. The symptoms of cotton seedlings caused by anthrax on cotton: The cotton seedlings were killed before being exhumed, and the hypocotyls and young roots were brown and rot, and the light victims could be exhumed. At the base of the diseased plant, reddish-brown small spots first appeared, and afterwards, the spots were dark-brown and slightly sunken. The edges were reddish-brown and severely dehydrated and the seedlings died. Cotyledons suffer from yellow or gray-brown round or semicircular lesions on the leaf margins. The lesions were inhibited under dry conditions and the edges were purple-red. The stems are damaged and dark round or long lesions appear. Afterwards, they are sunken and the epidermis is broken. When the climate is humid, orange-red sticky conidiophores can be produced. In the dry climate, the xylem cracks open, exposing fibers and eventually dies. 3. Fusarium wilt of cotton: Fusarium oxysporum f. sp. tritici can infect and damage cotton in the whole growth and development season of cotton. Under natural conditions, the susceptible cotton plants at the seedling stage can show symptoms about one month after sowing. During the period, the first peak of onset occurred, with a large number of wilting and death of cotton seedlings. During the summer high temperature season, the growth of pathogenic bacteria was inhibited, the disease development was slow, the symptoms were subtle, and it was rainy in autumn, the temperature dropped, the sickness grew vigorously, and a second onset occurred. peak. Cotton pests are mainly bollworms. Cotton bollworms parasitize the cotton and cause the growth point of the cotton to be damaged. The cotton bollworm larvae damage the leaflets around the apoencephalon into a lack of shape, there are fine insect feces, and the leaves are deformed after being unfolded; the cotton growing point is often destroyed, making the cotton stems At the top, the growth is stopped. The thick leggy branches grow from the top of the leaf blade below the top, but the basic buds are not long enough to make the whole cotton into a long-leaved, rodless, bare-stem cotton, commonly known as "public cotton." The top young leaves were eaten into many small perforations. In the comprehensive prevention and control strategy of cotton pests, generally based on the characteristics of the reproductive characteristics of cotton and the occurrence of pests, in the early period of cotton growth (in the late mid-July to enter the boundary of the drought), the protection of natural enemies was developed to give full play to the cotton. Compensation-based prevention and control strategies, while cotton bolls are mainly controlled by chemical pesticides. The report of the disease and disease report light is based on the principle of black light measurement of insect pests, and utilizes the characteristics of light, wave, color, and taste characteristics of insect pests, and integrates light trapping, wave, color, and taste trajectory into one, with modern technology. Physical trap equipment. It is a new ideal forecasting tool that can accurately predict the occurrence and occurrence of insect pests. For many years, station monitoring stations in many places have been using black lights to measure their reports. After 2003, the forecasting station began to introduce the report of the report of the disease and insects, and through the observation, the effect of the report of insects and insects was very significant. The performance of the report was better than that of the black light, which could effectively improve the forecast quality of the insects and pests and control the damage. Plays a good role.
