In the application of black light for the lure work, the following points should be noted:
(1) When black light is used for the measurement of phototaxis forest pests, the staff of the surveying and reporting staff is required to have a high sense of responsibility and skillful business techniques. It is necessary to do careful observation, detailed records, timely analysis and accurate measurement.
(2) Strive for black light equipment (such as black light wattage, etc.), installation location, height, number of days of lighting in one year, opening in one night, closing time, etc., should be consistent throughout the year, to achieve standard uniformity, easy to compare analysis.
(3) As a black light for measuring and reporting, a worm-incorporated worm box should be used to quickly kill the light to induce adult worms, keep the body intact, and help the species identification and quantity statistics of the pests.
(4) Black light should be installed on the open space with high position in the forest to make the light source unobstructed. The installation height depends on the type of forest pests reported.
(5) The black light used for monitoring should be turned on during the year from the early spring outing activities of forest pests to the late autumn wintering dormancy. If there is a purpose to induce a certain forest pest, the light can be turned on in the first half of the first period of the adult's first sight, and the light is turned off half an month after the adult is terminated.
(6) During the period of forecasting, in principle, the lights should be turned on all night, that is, the lights are turned on in the dark, and the lights are turned off in the daylight.
(7) Increasing the type of light source is conducive to improving the effect of attracting insects. In parallel with a fluorescent lamp or incandescent lamp next to the black light, the effect of attracting insects can be increased several times. At the same time, if the black light is surrounded, the four transparent blocks are added. The insect-resistant board made of glass can also more than double the amount of insects.
(8) After sorting and arranging the collected forest pests in the morning after the lights are turned on, the original data should be filled into the black light lamp to inspect the forest pests.
(9) It is necessary to strengthen the management and maintenance of black light, to prevent the occurrence of circuit disrepair, lamp damage, leakage of poison in the insect box, etc., so as to avoid accidents such as electric shock and poisoning to humans and animals. At the same time, it is necessary to pay attention to the dramatic increase in the number of pest populations in the light-sensing locations caused by the concentrated feeding of pests caused by the lamps, which should be eliminated in time.
