In recent years, with the increasing popularity of insect-resistant cotton, cotton cocoons have gradually risen as major pests, causing serious losses. In our district, the cotton-sucking beetle is mainly dominated by L. lucorum and L. japonicus. In order to explore a safe, non-toxic, pollution-free and low-cost prevention and control approach, a lure of insecticide was performed in 2010. The results of the test, the test results show that the trapping effect of the 12-watt electron-eliminating insecticidal lamp is better than that of the 16-watt electronic decoy insecticidal lamp; the trapping effect of the 16-watt electronic decoy insecticidal lamp against the black-claw Obviously better than 12 watts of electronic decoy insecticidal lamp, and the 16-watt electronic decoy insecticidal lamp in the cotton field is better than the 12-watt electronic decoy insecticidal lamp.
1. Test method Longqiao Village, Zoucheng Street was selected to be a contiguous piece of cotton field with flat terrain, convenient water source, good soil fertility, and convenient transportation. The total area was 13.33hm2, 6.67hm2 each, and 16W each was 16W. The lamp's two power-supply deceiving insecticidal lamps are respectively suspended in the two cotton fields. The 6.67 hm2 cotton field hoisting 16 watt lamp is abbreviated as a district, and the 6. 67 hm2 cotton field hoisting a 12 watt lamp is abbreviated as 2 districts.ç› Slide 1.5m away from the ground, 50m away from the light, conduct experiments on trapping and killing insects, see slide installation and location maps for experimental zones.
2. Methods and records The two slides are automatically designed to turn on the lights at night during the day. The 12 watts are purple and the 16 watts are pink. The pests are regularly cleaned at 7:30 in the morning and recorded according to the total insects. Percentage rate statistics analysis.
3. Results and analysis 3. 1 Comparison of two types of slide traps.
Table 1 The effects of two kinds of slide lamps on the killing effects of two species of blind stink bugs can be seen in Table 1. Under the same climatic conditions, fertilizer and water conditions, and the same plant species, the trapping effect of the two species is as follows: the kill rate in the two regions is 60.7%. The culling rate was 27.3%. The former was 33.4 percentage points higher than the latter. The trapping effect on the midge was 29.3%, the 1 area was 72.7%, and the former was 40.4% lower than the latter. The total culling effect: the cumulative amount of insects in the single lamp in Area 2 was 56. The cumulative insect population in Area 1 was 66, and the former was 15.2% lower than the latter.
3. 2 Comparison of two blind peak times The order of the peaks of each generation of L. lucidum was: 7/17~7/19 (three generations); 8/10~8/13 (fourth generation); 9/5~9 /7 (five generations).
The peaks of each generation of the genus Iris were sequenced as follows: 7/16~7/22; 8/7~8/8; 9/7~9/8, and the main peaks of the two species were similar (see Table 2). ).
Table 2 Comparison of the peak times of two generations of blind ticks 4 Summary and recommendations 4. 1 The 12-watt electron-induced lure lamp has a significantly better trapping effect on L. lucorum than the 16-watt electron-induced lure lamp.
4. The trapping effect of the 16-watt electronic decoy insecticidal lamp on black-sucking insects is significantly better than that of the 12-watt electronic decoy insecticidal lamp, and the total trapping effect of the 16-watt electronic decoy insecticidal lamp in the cotton field is better than 12 watts. Electronic temptation lamp.
4. 3 The use of electronic decoy insecticidal lamp to trap and kill insects has the advantages of no pollution, safety, and environmental protection. According to the visual inspection, it can be used to detect various types of tobacco moth, cotton bollworm, red bollworm, rice borer, rice planthopper, rice leaf roller, etc. There is also a booby trap effect, which does not significantly hinder crop growth.
5 Conclusion The 12-watt electronic decoy insecticidal lamp can be used in the cotton field dominated by the green locust; the 16-watt electronic decoy insecticidal lamp can be used in the cotton field mainly based on the mid-black maggot, and the mixed cotton field can be used 16 Watt's electronic temptation lamp.
6 Suggestions 6. 1 Insect bag joints are easily frayed after several times, unfavorable insects are removed, and the whole bag is changed to have no flash. And the quality of the bag is better.
6. 2 trapping insecticidal lamp high-voltage power grid is easy to loose, even the fire short circuit, fixed mesh wire should be on the insulating column to limit its sliding.
6. 3 attract insecticidal lamp high pressure wire welding point should be placed in the upper end of the canopy to prevent rain immersion.
6. The lower end of the hopper is made up of the size of the hopper. Do not add the leaf.
6. 5 The area of ​​the ceiling is slightly larger than the diameter of the funnel at the lower end to prevent rainwater.
