Frequency vibration insecticidal lamp control effect test
In recent years, due to the special climate, sudden forest pests have occurred seriously. Gypsum moths, caterpillars and other pests have exploded in the eastern part of Yingkou City, Liaoning Province. Large areas of natural secondary forests and tussah fields have been seriously damaged. The leaves were eaten light, and nearly 100,000 h of silkworm plague in the city could not be released normally, and the direct and indirect losses were serious. Under the condition that other prevention and control measures are not ideal, according to the strong phototaxis of lepidopteran pests and the similar characteristics of the two pests, the prevention and control test of the frequency-vibration insecticidal lamps was carried out, and the ideal control effect was obtained.
The use of frequency-vibration insecticidal lamps to trap the caterpillars and gypsy moths is basically normal distribution, which is basically the same as the two pests in this region. From the variation curve of the trapping quantity, it can be concluded that the adult larvae and the gypsy moth adult were first seen on June 28 and June 14 respectively. Compared with chemical control, the control of gypsy moth and the caterpillar caterpillar used more Killing Ding, when the cost of prevention and control is 140-160 yuan/h, it is much higher than the cost of the frequency-vibration insecticidal lamp, and it also kills the natural enemies and silkworms, and the use of insecticidal lamps avoids this problem.
It can be seen that the frequency-vibration insecticidal lamp can trap a variety of forest pests, especially the trapping of the caterpillars and the gypsy moths. Compared with the prevention and control of artificial egg picking, although the above two pests can adopt the method of egg removal and prevention, this method has high labor intensity and high labor costs. The daily wage per person is 40 yuan, and the cost of prevention and control is 5 days per hectare. At 200 yuan/h, the cost of prevention and control of each insecticidal insecticidal lamp is 37.8 yuan/h, which is 1/5 of the cost of artificial egg picking.
Frequency vibration insecticidal lamp 280 yuan per turn, 10h light every night, electricity costs 0.3 yuan per lamp, insect killing lights according to 60d calculation, a total of 18 yuan for electricity, labor costs 20 yuan per day, other accessories 60 yuan, a total of 378 yuan. 1 When the lamp can be controlled for 10 hours, the average cost of prevention and control can be calculated as 37.8 yuan/h. The above data shows that the use of frequency-vibration insecticidal lamps can save a certain amount of energy and cost, and is more convenient and effective than other traditional methods is a key advantage.
