In recent years, with the adjustment of agricultural structure, the types of crops have become increasingly diversified, the types of major pests have changed again, and the difficulty of treatment has increased year by year, and the demand for fruit products at home and abroad has become increasingly stringent. Therefore, an ideal is sought. Effective pollution-free pest management has become a top priority and this experiment was conducted for this purpose.
1 Materials and Methods
1.1 Materials
The Zaoyuan 3hm2, Lujia Village, Botou City, uses a solar-powered insect killer (produced by Zhejiang Top Instrument Co., Ltd.) to measure and control the forecast, with the model TOP and a power of 30W.
0133hm2, Nanzao Park, Zhangzhuangzi Village, Botou City, was monitored and treated with cotton bollworm sex attractants (the lure was 015mg/a).
Guotou Village, Botou City, 0166hm2, normal chemical control as a control.
The occurrence of pests in three jujubes is similar to that in the past, and the distance is more than 5km. They will not affect each other.
1.2 Methods
The Lujia Village Zaoyuan selected the central location as a test area. The solar insecticidal lamp was hung 2m away from the ground and fixed with wire to prevent wind sway. From June 5th to September 5th every night at 7pm. The lights were turned off at 5 o'clock the next morning and the trapped insects were collected to record the types and numbers of pests.
Zhangzhuangzi Zaoyuan from the May 15 to August 30 hung the bollworm lure core, 5 lure core /0133hm2, surveyed once a day the amount of moths, lures were replaced once a month.
The Guoyuan Village Zaoyuan was investigated from June 5 to September 5, and the investigation records were used to calculate the cost of pest control and pesticides.
Five trees were selected at random from the test park and the control park and on June 20th and September 5th. Each tree was selected from 5 branches in different directions to investigate and record the situation of leaf blow.
2 Results and Analysis
2.1 Monitoring effect
More than one hundred kinds of insect pests can be trapped by solar insecticidal lamps. Lepidoptera is the most common Lepidoptera, followed by Orthoptera, Hemiptera, Diptera and so on. The occurrence and development dynamics of Heliothis armigera H?bner, Ancylissativa Liu, Cnidocampaflavescens Walker, and Zeuzerasp. on the jujube tree were similar to those of natural surveys outside the experimental area, indicating that the solar insect lamp has a variety of pests Better monitoring effect. Take the Heliothis armigera H?bner as an example (Table 1).
Table 1 shows that the peak times of the moth traps of these two methods are basically the same, indicating that solar insecticidal lamps are feasible for the dynamic monitoring of pests and provide timely and accurate control basis for production.
2.2 control effect
The prevention and control effects are shown in Table 2. It can be seen from Table 2 that the intact rate of jujube leaf and fruit in the Lujia Village Test Garden is 96%, which is higher than that of sex attractants and chemical control. It can be seen that the use of solar insecticidal lamp to prevent and treat jujube tree pests has obvious effects. At the same time, it treats various pests of nearby farmland forests, other fruit trees and field crops, not only can control the hazards of the year, but also greatly reduce the population density, reduce the second The harm of the year also reduces the difficulty of controlling other pests and reduces the production cost. Sex attractants are highly effective but they are specific. The cost of chemical control is high, pollution is heavy, there is no selectivity to natural enemies, and it does not meet the requirements for the production of green food.
2.3 Control costs
Solar insecticidal lamp priced at 270 yuan each, can control the area of ​​3hm2, according to the two-year period of use, electricity charges 11 yuan per station per year, then the cost per hm2 is 4817 yuan; sexual lures per lure of 1 yuan, bowl Each 1 yuan, the annual cost of 300 yuan / hm2, is 612 times the insecticidal lamp; chemical prevention costs 900 yuan / hm2, removal of pest control lamps and other pests and other pest control costs 300 yuan, single The cost of controlling jujube pests is 1213 times that of insecticidal lamps.
3 Conclusion
Solar insecticidal lamps are easy to operate, safe to use, low in cost, large in control area, capable of accurately monitoring the occurrence of multiple pests in jujube trees, and have a significant insecticidal effect, and at the same time they have played a concurrent role in other forest fruit and crop pests. It is a new product that is practical, efficient and environment-friendly. It is recommended that it be widely used in production.
