Influence of the 2.1 different wave length spectrum to grey tea geometrid oviposition situation
Influence of the 1 different wave length spectrum of table to grey tea geometrid oviposition situation
| Processing | Single female egg laying amount/head | Single female highest egg laying amount/head | Spawning rate (%) | Preoviposition period (d) | Egg-laying season (d) |
| 590-595nm | 274.83±2.47b | 409 | 90 | 1.88±0.38a | 3.67±0.21b |
| 520-525nm | 242.53±2.39c | 367 | 83.33 | 1.93±0.33a | 3.43±0.57b |
| CK | 361.84±5.33a | 521 | 96.67 | 1.68±0.75a | 4.68±0.62a |
Note: the different letters of same column indicate that, in 0.05 horizontal upper significant difference, same letter indicates that difference is not significant.
As can be seen from Table 1, under two kinds of different wave length spectrum processing, the grey female egg laying amount of adults of ectropis obliqua list is substantially lower than
Natural light rearing conditions (CK).Single female egg laying amount has dropped 24% (yellow light) and 33% (green light) respectively, and difference reaches the level of signifiance.
Single female egg laying amount reduces by 112 and 154 respectively, hence it is evident that is lower than control treatment.In terms of spawning rate, the spawning rate of control is up to
96.67%, the spawning rate that yellow light and green light are handled is substantially reduced, and lighting process makes part adult not lay eggs.Two kinds of different waves
Under long spectral manipulation, preoviposition period of grey adults of ectropis obliqua postpones, but with the significance of difference of control group still in same level,
But the egg-laying season is obviously shortened, and 1.01d and 1.25d is respectively shortened, with compare up to the significance level of difference.
Illustrate that yellow spectrum and green spectral interfere significantly with the spawning habit of grey adults of ectropis obliqua, prolongs its preoviposition period
Long, the egg-laying season shortens, and egg laying amount decline, offspring flocks quantity is substantially reduced, and influences the expansion multiplying speed of its population.
Influence of the 2.2 different wave length spectrum to grey tea geometrid egg hatching rate
As seen from Figure 1, different wave length spectrum processing is affected to the hatching rate of grey tea geometrid ovum.Yellow light processing
Under, the hatching rate of ovum is 74.60%, and green light processing is 65.73%, and the egg hatching rate under the conditions of natural feeding is 83.33%,
The hatching rate for showing as ovum under the conditions of natural feeding is significantly greater than yellow spectrum and green spectral processing, difference between different disposal
Up to the level of signifiance.By Fig. 1, it can be concluded that, yellow spectrum and green spectral irradiate the hatching rate that can reduce grey tea geometrid ovum, make
Offspring flocks quantity is reduced, and reduces and quantity occurs, to reduce its harm.
Influence of the 2.3 different wave length spectrum to the grey adults of ectropis obliqua service life
Influence of the 2 different wave length spectrum of table to the grey adults of ectropis obliqua service life
| Processing | Male worm (d) | Female adult (d) |
| 590-595nm | 5.87±0.28a | 9.1±0.82a |
| 520-525nm | 6.12±0.44a | 9.7±0.15a |
| CK | 6.96±0.09a | 10.8±0.06a |
Note: the different letters of same column indicate that, in 0.05 horizontal upper significant difference, same letter indicates that difference is not significant.
As can be seen from Table 2, the service life of the lower grey tea geometrid male worm of yellow spectrum processing reduces 1.09d, at green spectral
Reason reduces 0.84d, and significance difference analysis is in same level.The service life of female adult is also reduced, respectively 1.7d and 1.1d,
Difference is not significant.It can be seen that two kinds of spectral manipulations have certain interference to the grey adults of ectropis obliqua service life, but have not yet been reached significant
It is horizontal.
Influence of the 2.4 different wave length spectrum to grey adults of ectropis obliqua eclosion rate
As seen from Figure 2, two kinds of wavelength are affected to the eclosion rate of adult after handling grey tea geometrid pupa.Green light processing
Under, eclosion rate 57.77%, yellow light 45.09%, and the eclosion rate compareed is up to difference between 82.25%, three processing up to significantly
It is horizontal.Illustrate that the irradiation of yellow light and green-light source has significantly affected the emergence number of grey adults of ectropis obliqua, hence it is evident that drop is to offspring flocks
Quantity.
