Description
Technical Field
The invention relates to the technical field of crop disinsection.
Background
Insect pests have become a major problem currently affecting the growth and quality safety of agricultural crops. The species of the farmland crop pests mainly comprise Helicoverpa armigera of Lepidoptera, corn borer, armyworm, Athetis lepigone, dichocrocis punctifera, other moths, scarab beetle of Coleoptera and the like. The cotton bollworms are eating impurities and almost can harm all farmland crops such as cotton, corn, millet, sorghum, vegetables and the like; the corn borers mainly damage crops such as corns, broomcorn, millet and the like; armyworm mainly harms crops such as millet, corn, sorghum and the like; athetis lepigone mainly damages summer corn seedlings; dichocrocis punctiferalis mainly damages sorghum, corn, fruit trees and the like; the chafer larva is an important underground pest, and adults eat various crops such as corn, millet, sorghum, vegetables and the like for harming; the rice is mainly harmed by snout moth pests such as cnaphalocrocis medinalis, chilo suppressalis, tryporyza incertulas and the like. The pests are distributed in various ecological types, the main pest types in different areas are different, but the damage is serious, and the plant damage rate of crops can reach more than 30% to 90%. Besides directly eating the fruit ears to influence the yield, the damage of insect pests is more likely to cause ear rot and generate chemical substances such as aflatoxin, fumonisin and the like which are harmful to the health of people and livestock, thereby seriously influencing the safety of food and animal husbandry.
The insect pest is large in population, strong in reproductive capacity and capable of alternatively generating in peak periods of several insects, the chemical control is carried out by spraying for many times, the control effect is achieved, the control cost and the dosage are greatly increased, and the insect pest control method does not accord with the green control policy advocated by the state. Particularly, the control effect of multiple medication is very little for the spike worms in the later period of the corn and after boring the female spike, so that farmers are more competent and do not take control measures, thereby causing the problems of corn yield loss and quality safety.
The adult pests appear at night in many days, and researches show that the activity rule of the pests mostly move and cross in the height range of 25cm-100cm above the canopy of crops. At present, the technical means for trapping and killing the pests by adopting the insecticidal lamp is adopted, the growth of crops is a process of gradually growing from low to high, and the height of the insecticidal lamp adopted at present is not adjustable, so that the insecticidal lamp cannot be ensured to be positioned in the range of the pests above a canopy, the highest design of the insecticidal lamp used at present is 3.5 meters, the plant height of the crops such as corn, sorghum and the like after the crops are spilt can reach about 2.7 meters, and the highest height of waxy corn can reach 3.5 meters, therefore, the lamp tube of the insecticidal lamp installed in the farmland can not expose the canopy after the crops grow high, and the trapping effect of the pests is seriously influenced, or the insecticidal lamp is higher than the canopy of the crops by more than 25cm at the early growth stage of the crops and is higher than the range of the pests, so that the insecticidal effect is not high. The use and the popularization of the insecticidal lamp on insect pest prevention and control are limited. The female insects in the egg laying period before the early spring overwintering generation of one pest can lay eggs for 300-500 grains, and because the pest killing lamp only traps and kills the pests in the egg laying period before the early spring overwintering generation of the pest, the geometric index of the number of the second or third generation larvae is increased.

Experimental data:
20-28 days in 2018, carried out in a corn demonstration base in Pingxiang county, four lamps are spaced at 200 meters, a No. 4 lamp tube with the length of 422mm is adopted as the insecticidal lamp, the main peak of the light wavelength of the light source emitted by the lamp tube is 360-440 nm, the height of the lower edge of the insecticidal lamp is 25cm higher than the top of a corn plant, 25cm lower than the top of the corn plant and 75cm lower than the top of the corn plant (respectively marked as 25cm, -25cm and-75 cm), the height of the insecticidal lamp is alternately adjusted every day, and the total quantity of borer pests such as corn borers, cotton bollworms and the like and scarab pests is counted. The moth-trapping amount is the largest when the insecticidal lamp is 25cm higher than the canopy of the corn plant (see table 1).
TABLE 1
| Insecticidal lamp higher than corn canopy (cm) | Daily quantity of insecticide |
| 25 | 122 |
| -25 | 36 |
| -75 | 7 |
As can be seen from Table 1, the height of the insecticidal lamp above the crop canopy is the primary factor affecting the trapping effect. So that the height of the insecticidal lamp can be adjusted, which is very important for the insecticidal effect.
In 2019, 8, 28 days to 9, 7 days, further tests are carried out in a Pingxiang corn demonstration base, the height of an insecticidal lamp is set to be 0, 0.5, 1 and 1.5m away from the top end of a corn plant, the insecticidal lamp adopts a No. 4 lamp tube with the length of 422mm, the main peak of the light wavelength of a light source emitted by the lamp is 360-440 nm, the height of the insecticidal lamp is alternately adjusted every day, the total quantity of snout moth pests such as corn borers, cotton bollworms and the like and scarab pests is counted (see table 2),
TABLE 2
As can be seen from Table 2, the lamp tube has the best insecticidal effect when being 1m higher than the crown layer. For pests in the early period, adult activity mainly moves nearby above the canopy, so the trap amount of the pests 25cm above the canopy is the largest, and the pests in the later period are few, the adults diffused from the adjacent area are mainly trapped and killed, the flying height is higher, and the trapping and killing effect of the pests 1m above the canopy is the best. The data in table 3 show that the 4# special lamp tube has a remarkable trapping effect on various lepidoptera and coleoptera pests compared with the conventional lamp tube.
Time for trapping and killing by turning on lamp
Setting two lighting times, lighting for trapping and killing in 3 and 15 days in 2018, starting to trap and kill in 10 days in 8 and 8 in 2018 and contrasting with the three plots without lighting, wherein the insecticidal lamp adopts a No. 4 lamp tube with the length of 422mm, the main peak of the light wavelength of the emitted light source is 360-440 nm, and the percentage difference of the panicle insect rate under different conditions is investigated (see table 3).
TABLE 3
| Time of turning on lamp | Properties of pests | Ear worm rate (%) |
| 3, 15 and 2018 | Trapping and killing overwintering generation pests | 1 |
| 8 month and 10 days 2018 | Trapping and killing harmful pests | 53 |
| Not putting lamp | Not trapping and killing pests | 82 |
The results in Table 3 show that the trapping, killing and preventing effects of the overwintering generation imagoes are very obvious, and the population density of the imagoes at the later stage is greatly reduced, so that the damage to the corns is reduced.
