(1) The frequency-vibration insecticidal lamp has a wide spectrum of attracting insects, and has good trapping effect. It has a large trapping effect on cotton and rice pests, and has less trapping effect on natural enemies, lower energy consumption, and excellent comprehensive effect. Other lamps such as light lamps. Because the insecticidal lamp uses the physical method to eliminate the pests before the oviposition, it reaches the purpose of reducing the density of the insects and reducing the damage.
The control effect on important pests such as cotton bollworm and stem borer can reach 40%-60%. Using insecticidal lamps to eliminate insects and reducing the use of chemical pesticides 1-3 times is beneficial to protect natural enemies and has significant social and ecological benefits. It is worth promoting.
(2) According to the characteristics of trapping insect pests by frequency-vibration insecticidal lamps, and the occurrence of major pests in farmland, the use of insecticidal lamps to control pests should be used in pieces to achieve better results. It is best to organize them in units of villages. , unified management, unified maintenance. Large-scale use, using grid format cloth, the distance between the lamp and the lamp is 180)200m. It is used in cotton field, the lighting time is from the beginning of June) at the end of September, it is more suitable to light from 8:00 to 5:00 pm every night; The use of the rice in the rice season is more suitable from the peak of the emergence of the second generation of the phlegm and phlegm on May 15 to the end of the third generation of the dynasty of the dynasty. It is used in the pure single-season rice area and can be opened from the end of June to August 25. Lights are more suitable for lighting from 8 pm to 5 pm every night.
(3) The use of insecticidal lamps to control crop pests is only one of the measures in comprehensive prevention and control, and it is necessary to cooperate with other measures to achieve better results.
In the prevention and control of cotton pests and diseases, it is still necessary to prevent and control diseases and insect pests such as aphids, cotton leafhoppers, cotton locusts, etc., and the second-generation and fourth-generation cotton bollworms and Spodoptera litura can reduce the number of prevention and control. Apply at the peak of young larvae. In the prevention and control of rice pests and diseases, we must pay attention to the prevention and control of pests and diseases of rice leaf roller, rice blast, and other diseases. On the basis of not relaxing the control of sloping fields, reduce the number of use of chemical pesticides in Daejeon, and second-generation and third-generation Hey, master the medicine at the peak of egg hatching, and the main damage generation of rice planthopper should also pay attention to prevention and treatment.
(4) The use of insecticidal lamps requires cleaning the high-voltage network every day, which brings inconvenience to the use management. In addition, the insect tray of the insecticidal lamp is not smooth enough, the slope is small, and some insects are not easy to fall into the bag and escape. Improve. In the rice area, it is recommended that the factory develop a special lamp for trapping aphids, rice planthoppers, and leafhoppers. In addition, trapped insects can be used for aquaculture for comprehensive utilization.
