Study On Applied Fundamental Technology Of Vibration-type Insecticide Lamp In Phyllostachys Praecox

Phyllostachys praecox is an excellent bamboo species unique to China and occupies an important position in the economic development of bamboo producing areas.With the growing area of bamboo forest,the biodiversity and ecosystem stability of bamboo forest are decreasing.Increasingly rampant bamboo pests have become one of the important factors restricting the development of bamboo industry.In order to control insect pests in Phyllostachys praecox effectively,frequency vibration insecticidal lamp was applied to control pests in Phyllostachys praecox for the first time.Six insecticidal lamps with different wavelengths were selected for the experiment.The light source was 365 nm(A),380 nm(B),395 nm(C),and 420 nm(D),460 nm(E),and 520 nm(F).In order to clarify the insect species and composition under the light of Phyllostachys praecox and the occurrence dynamics of the main pests,to determine the trapping and killing effects of different light sources on the main pests,to study the upper light rhythm of the main pests,to explore the scientific use of insecticidal lamp control technology with medium frequency vibration of Phyllostachys praecox.The results are as follows:1.The experiment lasted 92 days.The insects trapped by the lamps were 120 species in 53 families and 11 orders,and the total number of insects was 76,314,and 24,399 species were identified.According to the total number of insects in each order,Lepidoptera and Coleoptera were the main insects during the experiment,Hemiptera,Diptera and Hymenoptera take second place,Orthoptera,Mantids,Pulptera,Euryptera,Dragonfly and Homoptera were relatively few.There are 4 main insect pests of bamboo shoot under the lamp,including Oligia vulgaris,Kumasia kumaso,Melanotus cribricollis,Chiagosnius sulcicollis.There are 6 kinds of main bamboo leaves pests under the lamp,including Algedonia coclesalis,Cicadella viridis,Circobotys aurealis,Eumorphobotys eumormorphalis,Eumorphobotys obscuralis,Latoia bicolor and Pantana sinica.There are two main insect pests of bamboo branch and pole under the lamp,including Hippotiscus dorsali and Aeneria pinchii.2.Research shows that the peak period of four kinds of light traping bamboo shoot pests are mainly distributed in the mid-June to mid-july.Six kinds of light traping main bamboo pests at the peak of the trap has a big overlap,can focus on prevention and control in July.The peak period of two kinds of bamboo pole pests are mainly distributed in mid to late July.In summary,the period when phyllostachys praecox stands was most damaged by major pests was concentrated in mid-June,mid-July,late July and early August,and they are also the most critical period for pest control.3.According to the results of observation of circadian rhythm,Algedonia coclesalis and Eumorphobotys obscuralis had similar trapping peaks,and there is a large overlap between 20:00-22:00,Latoia bicolor are trapped the most from 00:00 to 02:00.Therefore,for these three kinds of pests,turn on the lights for control in the corresponding time period,which has a high trapping efficiency and saves the cost of prevention and control.It is the best time to turn on the lights to trap.4.According to the test results,combined with the types of bamboo shoot pests,among the six wavelength insecticidal lamps,the trapping lamp 395nm(C)can be used to control the pests in the phyllostachys praecox stands.This lamp not only has the best trapping effect on Coleoptera pests such as Melanotus cribricollis(Faldermann)and Chiagosnius sulcicolis Candeze and Hemiptera pests such as Hippotiscus dorsalis stal and Notobitus meleagris Fabricius,but also has certain effects on Lepidoptera pests.It has good comprehensive control ability.In addition,the trapping lamp 365 nm(A)has the best trapping effect on Lepidoptera of bamboo forest,suitable for use in bamboo forests heavily infested with lepidoptera insects such as Oligia Vulgaris Butler,Algedonia Coclesalis Walker,Latoia Bicolor Walker.The trapping lamp 520 nm(F)has the best trapping effect on Hymenoptera and Hemiptera,suitable for Hymenoptera insects such as Aiolomorphus rhopaloides Walker,Tetramesa phyllostachitis Gahan and hemiptera insects such as Hippotiscus Dorsalis stal,Notobitus meleagris Fabricius that do serious harm to bamboo forests.
