In order to validate Zhejiang Top Instrument Co., Ltd. modified insecticidal lamp (TPSC1-2), new-generation solar insecticidal lamp (TPSC3-4 type), lifting solar insecticidal lamp and self-cleaning automatic agricultural spectrum insecticidal lamp Insect Infestation Effect, July-September, We carried out the relevant trials. The summary is as follows:
1 Test materials and methods
1.1 Test Fixtures Retrofitted solar insecticidal lamp (TPSC1-2) and a new generation of solar insecticidal lamp (TPSC3-4), lifted solar insecticidal lamp, self-cleaning automatic agricultural spectrum insecticidal lamp.
1.2 Test site The experiment was selected in the Dahong Vegetable Garden. The vegetable area is relatively large and the terrain is open and flat.
1.3 Test methods
(1) Test time: July-September 2007. (2) Experimental design: Development of modified solar insect killer lamp (TPSC1-2 type), new-generation solar insect killer lamp (TPSC3-4 type), lift solar insecticidal lamp and self-cleaning automatic agricultural spectrum insecticidal lamp Contrast test on species and number of trapped insect pests, the height of the four lamp traps is basically the same, according to the design of the TPSC 1-2 solar insecticidal lamp, corresponding to the PS-IIIII type solar insecticidal lamp, lifting solar insecticidal lamp and automatic agricultural spectrum The height of the insecticidal lamp, according to the actual situation, chooses a height of about 130cm, and 4 lamps are installed in the adjacent position. Conduct comparative tests on the number and types of TPSC 1-2 solar insecticidal lamp, solar-powered insecticidal lamp, and automatic agricultural insecticide lamp. (3) Test investigation: Record the types and amounts of beneficial insects and pests under the lamp and weigh them, and investigate once every 5 days.
2 Test results and analysis
2.1 After being observed for 3 months, the beneficial insects and pests that were trapped and killed were found to be beneficial to the two kinds of beetle and coccothrax. According to the analysis of the trapping situation in the past 3 months from July 5th to September 30th, the ratio of hazards of the 4 types of solar insecticidal lamps is: The ratio of harm to damage of the new-generation solar insecticide lamp is 1:187; The modified solar insect killer lamp (TPSC1-2 type) Benefit ratio 1:87; Elevated solar insect killer ratio 1:98; Automatic agricultural insecticidal lamp benefit ratio 1:107.
2.2 Comparison of species of insect pests The trapping spectrum of solar insecticide lamps produced by different units in the experiment is basically the same, and it can basically be trapped on several kinds of insect pests like night beetles commonly found on vegetables, such as Spodoptera exigua, Spodoptera litura, Plutella xylostella, small tigers, pods, melon pods, beans, etc.
2.3 Comparison of insect pests Weighing insects in the last 3 months from July 5 to September 30 Weighing: Weighing insects from more to fewer: The new-generation solar insect killer (PS-IIIII) is 622.8 g; The converted solar insecticidal lamp (PS-III type) is 503.1g; the automatic agricultural spectrum insecticidal lamp is 370.8g (due to the relatively late installation, the amount of trapped insects is relatively less); the lifting solar insecticidal lamp is 265.1g.
3 Summary From the above data analysis, a new generation of solar insecticidal lamp trapping effect and automatic agricultural insect trap lamp effect is better. Although the solar-powered insecticidal lamp has the function of being able to move freely, it attracts less insects, especially the seizure ability of the beetle is worse than that of the other three lamps, and it is prone to technical problems, causing the insecticidal lamp to fail to work properly. It is recommended to promote the use of a new generation solar insect killer lamp in production.
4 It is recommended that the four solar insecticidal lamps be used during the course of use. If rain or cloudy weather occurs, the lights will not be on the night of the second night even in the evening, affecting the effect of attracting insects. In order to make the solar insecticidal lamp play its best role, it is recommended to charge the solar insecticidal lamp battery in time according to the battery charger for weather forecast.
