Significance of difference was calculated using SPSS 25. The data in the same column are labeled with different lower case letters indicating significant differences at a level of P < 0.05 as determined by the LSD test difference detection method.
From table 3 it can be derived: the number of times of disturbance is the lowest in the invention, and is only 5.00 times, and the other three devices are all obviously higher than the invention, wherein the number of the culture dishes is 29.33 times, which is about 6 times of the invention; the number of the transparent plastic tanks is 20.00 times, which is 4 times of the number of the transparent plastic tanks; the number of the tiny insect breeding boxes is 14.00 times, which is about 3 times of the invention (F) 3,11 =171.318,P=0.000)。
The escape rate of the tomato leaf miner adult insects observed in different devices is the lowest in the invention and is 0, the escape rate of the tomato leaf miner adult insects observed in different devices is 11.00 percent when the tomato leaf miner adult insects are raised in a culture dish and a tiny insect raising box, and the escape rate of the tomato leaf miner adult insects observed in a transparent plastic tank is 18.00 percent when the tomato leaf miner adult insects are raised in a transparent plastic tank for the second time (F) 3,11 =221.333,P=0.000)。
Firstly, analyzing the feeding result of the tomato leaf miner:
the results of feeding the tomato leaf miner show that the feeding device for the tomato leaf miner is obviously superior to the feeding method of the traditional culture dish, the transparent plastic tank and the tiny insect breeding box. The feeding device and the method are suitable for independently feeding the tomato leaf miner. As can be seen from the experimental species for breeding the tomato leaf miner, the breeding device has the advantages that the wall body is transparent, the change of moisture can be observed, so that the moisture is supplemented, and meanwhile, the ventilation net is arranged at the topmost part of the device, so that the moisture can be prevented from being condensed in the device, and further the observation is influenced.
Traditional culture dish is because only wrap up wet cotton for isolated plant leaf and keep water, but cotton moisture volatilizees soon, leads to the leaf very easily to die because of the lack of water, simultaneously because the reason of culture dish itself, leads to the larva to insert and moisturizing time on the long side. Therefore, the traditional method for breeding a large amount of single-head tomato leaf miners is long in time and labor-consuming, and the death rate of leaves is higher.
And transparent plastic tank is owing to need be to the lid screw and unscrew to this requirement to time is much higher than other devices, because the inside moisturizing device of transparent plastic tank is the centrifuging tube that punches simultaneously, therefore very easily leads to the blade deformation rate high, and then influences subsequent observation experiment.
The tiny insect feeding box needs a frame or a rubber band for re-fixing when being opened and closed, so that the operation time can be prolonged.
(II) analysis of results of observation experiments on tomato leaf miner
The observation experiment result of the tomato leaf miner shows that the observation device adopted by the invention is also obviously superior to three traditional devices, namely a culture dish, a transparent plastic tank and a tiny insect feeding box.
The observation device and the observation method are suitable for the tomato leaf miner. As can be seen from observation experiments of tomato leaf miners, the observation device has the characteristics of less times of disturbance, low escape rate of adults and the like. The other three devices are all higher than the present invention. The culture dish, the transparent plastic tank and the tiny insect feeding box are inconvenient to move due to the small width of the device, so that the number of times of the imagoes is increased; similarly, the traditional device needs to be opened and closed for water replenishing, the escape rate is high because the adult tomato leaf miner is active, and the tomato leaf miner cannot escape because an observation room does not need to be opened and closed during water replenishing.
Although the present invention has been described in detail with respect to the apparatus for individually raising and observing tomato leaf miner, the method of use and the results thereof, the present invention can be used to individually raise and observe small insects such as parasitoid wasps, cabbage caterpillars, green lacewings, predatory mites, ladybirds and ants by slightly adjusting the size of the soft rubber of the observation apparatus, the type of the leaves in vitro, the size of the observation chamber and the water replenishing chamber.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
